Description

Technical Field

[0001] The present invention relates to a cutting device for tatami mats used for tatami mats such as seamless tatami mats and bordered tatami mats, for example.

[0002] More specifically, the present invention particularly relates to a cutting device for tatami mats for cutting a tatami mat such that, in a cross-sectional view, the upper part is a vertical plane (blade insertion depth H) in the vertical direction and the lower part is an inclined plane (cutting angle) inclined inward.

Background Art

[0003] Conventionally, when manufacturing a tatami mat, before sewing or pasting the tatami mat surface, the tatami mat floor is cut to a predetermined size by a cutting device for the tatami mat floor.

[0004] In this case, as shown in FIG. 16, for the cutting on the side of the frame 402, in order to easily spread out the tatami mat, in a cross-sectional view, the upper part of the tatami mat floor 400 is a vertical plane 408 in the vertical direction, and the lower part is an inclined plane 412 inclined inward to cut the tatami mat floor 400.

[0005] In such cutting, as shown in FIG. 16, when manufacturing a thick tatami mat (for example, thickness 30 mm to 60 mm), the tatami mat floor 400 is cut at a cutting angle α of about 8° with respect to the vertical plane 408 of the tatami mat floor 400.

[0006] On the other hand, when manufacturing a thin tatami mat (for example, thickness less than 10 mm to 30 mm), the tatami mat floor 400 is cut at a cutting angle α of about 13° with respect to the vertical plane 408 of the tatami mat floor 400.

[0007] In order to realize such a cutting state, as conventional cutting devices for tatami mat floors, for example, cutting devices for tatami mat floors as disclosed in Patent Document 1 (Japanese Patent Application Laid-Open No. 2010-042505), Patent Document 2 (Japanese Patent Application Laid-Open No. 2009-166174), and Patent Document 3 (Japanese Utility Model Laid-Open No. 1983-169994) are disclosed.

[0008] In both Patent Document 1 and Patent Document 2, in order to address the difference in cutting angle α for thick and thin tatami mats, a virtual pivot center is provided in the tatami mat cutting device, and the cutting angle α is made changeable.

[0009] Furthermore, as shown in Figure 17, the tatami mat cutting device 300 of Patent Document 3 is provided with a pivot 302, which is the actual axis, and the tilting table 304 can be fixed at any tilt angle around this pivot 302, thereby enabling the angle of the cutting angle α to be changed.

[0010] In other words, as shown in Figure 17, in Patent Document 3, a tilting table 304 supported by a pivot 302 is attached to a feed table 306. Furthermore, the head of the bolt 308, which is fitted into the upper part of the tilting table 304, protrudes from the arc groove 310 provided in the bracket of the feed table 306, and is fastened with a fastening member 312 such as a nut.

[0011] Since the arc groove 310 is arc-shaped with respect to the pivot 310, the tilting base 304 can be fixed at any angle. The intermediate cutter 314 and the successor cutter 316 are attached to the tilting base 304 via vertically elongated holes and bolts, respectively, so that their vertical positions can be adjusted. [Prior art documents] [Patent Documents]

[0012] [Patent Document 1] Japanese Patent Publication No. 2010-042505 [Patent Document 2] Japanese Patent Publication No. 2009-166174 [Patent Document 3] Utility Model Publication No. 1983-169994 [Overview of the Initiative] [Problems that the invention aims to solve]

[0013] By the way, when manufacturing thick tatami mats and thin tatami mats, it is desirable to adjust (change) the cutting angle α of the tatami base 400 relative to the vertical surface 408 of the tatami base 400, as well as the cutting depth H of the vertical surface 408 of the tatami base 400.

[0014] As shown in Figure 18, the tatami mat cutting device 100 of Patent Document 1 has a rotating blade 106 on a support part 104 that is movable along a rail 102.

[0015] The rail 102 is supported by a lifting cylinder 108 supported by a frame 114. This configuration allows a support part 104 that moves along the rail 102 and a rotating blade 106 provided on the support part 104 to move up and down relative to the tatami mat floor 400 placed on the table 112.

[0016] As a result, when manufacturing thick tatami mats and thin tatami mats, the cutting angle α of the tatami base 400 with respect to the vertical surface 408 of the tatami base 400 is modified in both cases.

[0017] However, the tatami mat cutting device 100 in Patent Document 1 is described as having a configuration that does not allow for adjustment (change) of the cutting depth H of the vertical surface 408 of the tatami mat 400, regardless of the tilt of the tilting body 116, as the virtual tilting axis P is always in the same position relative to the tatami mat 400 placed on the table 112.

[0018] On the other hand, as shown in Figures 19 to 20, the tatami mat cutting device 200 of Patent Document 2 includes a frame 202 arranged in the cutting direction and a traveling member 204 that travels along this frame 202. Furthermore, it includes a support base plate 208 fixed to the running member 204, which has multiple arc-shaped elongated holes 206, 206 that share a pivot center P at a single point passing through the cut surface.

[0019] The blade base 212 is provided with multiple pins 210, 210 embedded in multiple arc-shaped elongated holes 206, 206 of the support base 208, into which each pin is inserted. It is provided with a blade assembly 218 which consists of a circular cutting blade 216 mounted on a mount 214 fixed to the blade substrate 212 for this tool and rotated by a motor.

[0020] And, the relative position of the blade substrate 212 with respect to the support substrate 208 is configured such that the angle of the circular cutting blade 216 can be set by the rotation (C direction) of the blade substrate 212 about the rotation center P.

[0021] In addition, in FIGS. 19 to 20, for the sake of convenience of explanation, the case of cutting the tatami mat 400 at a cutting angle α of about 8° is illustrated.

[0022] And, in the tatami mat cutting device 200 of Patent Document 2, as shown in FIG. 19, when manufacturing a thick tatami mat (for example, thickness 30 mm to 60 mm), at the blade penetration depth H of the vertical surface 408 of the tatami mat 400, and with respect to the vertical surface 408 of the tatami mat 400, the tatami mat 400 is cut at a cutting angle α of about 8°.

[0023] On the other hand, in the tatami mat cutting device 200 of Patent Document 2, as shown in FIG. 20, a spacer 224 is disposed below the floor presser 222. Thereby, when manufacturing a thin tatami mat (for example, thickness less than 10 mm to 30 mm), at the blade penetration depth H of the vertical surface 408 of the tatami mat 400, and with respect to the vertical surface 408 of the tatami mat 400, the tatami mat 400 is cut at a cutting angle α of about 13°.

[0024] However, in the tatami mat cutting device 100 of Patent Document 1, a lifting mechanism such as a lifting cylinder 108 must be provided, which has a complicated structure, a large number of parts, and high costs.

[0025] Also, in the tatami mat cutting device 200 of Patent Document 2, in the case of a thin tatami mat, a spacer 224 must be disposed below the floor presser 222, which requires complicated processes, takes time and effort, and results in high costs. Furthermore, it is necessary to prepare spacers 224 of multiple heights to match the thickness of the tatami mats, which requires a complicated process, is time-consuming, and results in high costs.

[0026] Furthermore, in devices such as those described in Patent Documents 1 and 2, where a pin shaft engages with an elongated hole and rotates around the pivot axis of a virtual shaft, minute gaps and looseness make it impossible to set an accurate cutting angle α and cutting depth H.

[0027] On the other hand, the tatami mat cutting device 300 of Patent Document 3 does not consider, at all, the adjustment (change) of the cutting angle α of the tatami mat 400 relative to the vertical surface 408 of the tatami mat 400, in addition to changing the cutting angle α of the tatami mat 400 relative to the vertical surface 408 of the tatami mat 400, when manufacturing thick tatami mats and thin tatami mats.

[0028] In view of the current situation, the present invention aims to provide a tatami mat cutting device that allows for easy setting of the precise cutting angle α and blade depth H when manufacturing thick tatami mats, thin tatami mats, and tatami mats of sizes other than conventional sizes, has a simple structure, eliminates complicated processes, saves time and effort, and reduces costs. [Means for solving the problem]

[0029] The present invention was made to achieve the problems and objectives of the prior art described above, and the tatami mat cutting device of the present invention is Tatami floor A frame member positioned along the cutting direction of the side to be cut, A running member that is movable along the cutting direction of the frame member, Connected to the aforementioned traveling member 、 A tilting member configured to be able to tilt about a pivot center in a direction perpendicular to the cutting direction, A cutting device for cutting the side edge of a tatami mat, comprising: a tilting member provided with a rotating blade for cutting the tatami mat at an inclined angle in cross-section; The pivot point of the tilting member is located at the lower end of the tilting member, above the cutting position X of the tatami mat base. 、 When cutting a tatami mat base, the end of the floor-holding member that is positioned on the upper surface of the tatami mat base along the side of the tatami mat base to be cut. and It is positioned so as not to interfere with the side to be cut, and the cutting angle α of the tatami mat relative to the vertical surface of the tatami mat is determined according to the thickness of the tatami mat. Adjustments , the depth of cutting into the vertical surface of the tatami mat base H too adjustment It is possible It is characterized by the following:

[0030] With this configuration, the pivot point of the tilting member is located at the lower end of the tilting member, above the cutting position X of the tatami mat base, and the pivot point of the tilting member is positioned so as not to interfere with the end of the floor-holding member on the side of the tatami mat base that is cut along the side of the tatami mat base that is cut when the tatami mat base is cut.

[0031] Therefore, even when the tilting member rotates to set the cutting angle α of the tatami mat with respect to the vertical surface of the tatami mat, it does not interfere with the end of the floor-holding member on the side of the tatami mat that is to be cut.

[0032] Furthermore, the cutting angle α of the tatami mat with respect to the vertical surface of the tatami mat, and the cutting depth H of the blade into the vertical surface of the tatami mat, can be adjusted according to the thickness of the tatami mat base.

[0033] As a result, when manufacturing thick tatami mats, thin tatami mats, or tatami mats of sizes other than conventional sizes, it is possible to easily set the precise cutting angle α and cutting depth H. Moreover, it is possible to provide a tatami mat cutting device with a simple structure, no complicated processes required, requiring little effort or time, and reducing costs.

[0034] Furthermore, the tatami mat cutting device of the present invention is In the cutting direction of the tatami mat base, it is positioned upstream of the rotating blade and connected to the running member. 、 It is characterized by having a vertical cutting blade positioned perpendicular to the cutting direction.

[0035] With this configuration, the tilting member tilts around the pivot center in a direction perpendicular to the cutting direction, and the rotating blade provided on the tilting member tilts around the pivot center at a cutting angle α of the tatami mat relative to the vertical plane of the tatami mat. This makes it possible to maintain a vertical cutting blade in a direction perpendicular to the cutting direction.

[0036] Therefore, the vertical cutting blade positioned upstream of the rotating blade cuts the upper part of the tatami mat in a direction perpendicular to the cutting direction. After that, the tilting member is tilted around the pivot point, and the rotating blade provided on the tilting member allows for precise cutting at the cutting angle α of the tatami mat relative to the vertical surface of the tatami mat.

[0037] Furthermore, the tatami mat cutting device of the present invention is The vertical cutting blade is characterized by being configured to be movable up and down.

[0038] By configuring it in this way, the depth to which the upper part of the tatami mat is cut vertically in a direction perpendicular to the cutting direction can be adjusted by moving the vertical cutting blade up and down.

[0039] Furthermore, the tatami mat cutting device of the present invention is The floor-holding member is characterized in that the end of the tatami mat base that is to be cut has an inclined surface on the cutting side so as not to interfere with the running member and the tilting member.

[0040] With this configuration, the end of the floor-holding member on the side of the tatami mat that is to be cut has a shape that has an inclined surface on the cutting side, so that it does not interfere with the running member and the tilting member.

[0041] Therefore, even when the tilting member rotates to set the cutting angle α of the tatami mat with respect to the vertical surface of the tatami mat, the running member and the tilting member do not interfere with the end of the floor-holding member on the side of the tatami mat that is to be cut.

[0042] Furthermore, the tatami mat cutting device of the present invention is The tilting member connected to the aforementioned traveling member is configured to be movable horizontally with respect to the side of the tatami mat to be cut.

[0043] With this configuration, the tilting member connected to the running member is configured to be able to move horizontally with respect to the side of the tatami mat to be cut. Therefore, by adjusting the tilting member in the horizontal direction, the cutting angle α of the tatami mat with respect to the vertical surface of the tatami mat, and the cutting depth H of the blade into the vertical surface of the tatami mat, can be adjusted steplessly and accurately according to the thickness of the tatami mat.

[0044] As a result, the cutting angle α and blade depth H can be easily and precisely set steplessly, whether manufacturing thick tatami mats, thin tatami mats, or tatami mats of non-conventional sizes.

[0045] Furthermore, the tatami mat cutting device of the present invention is The aforementioned traveling member is equipped with a horizontal bracket member, The horizontal bracket member is provided with a tilting portion horizontal movement member that is connected to it so as to be movable in the horizontal direction, The tilting member is characterized in that it is connected to the horizontally moving tilting member so as to be able to tilt around the pivot center.

[0046] By configuring it in this way, the tilting horizontal movement member can be adjusted to move horizontally relative to the horizontal bracket member, and the tilting member can be adjusted to tilt around the pivot center relative to the tilting horizontal movement member, thereby accurately adjusting the cutting angle α of the tatami mat with respect to the vertical surface of the tatami mat, and the cutting depth H of the blade into the vertical surface of the tatami mat, according to the thickness of the tatami mat.

[0047] Furthermore, the tatami mat cutting device of the present invention is The horizontal bracket member has a horizontal guide groove extending in the horizontal direction. The tilting horizontal movement member is provided with a horizontal movement fixing member. By sliding and fixing the horizontal movement fixing member of the tilting portion horizontal movement member into the horizontal guide groove of the horizontal bracket member, The tilting portion horizontal movement member is configured to be movable and fixed horizontally relative to the horizontal bracket member.

[0048] By configuring it in this way, the horizontal movement fixing member of the tilting section horizontal movement member can be slid and fixed into the horizontal guide groove of the horizontal bracket member, thereby allowing the tilting section horizontal movement member to be moved and fixed horizontally relative to the horizontal bracket member.

[0049] As a result, the cutting angle α of the tatami mat with respect to the vertical surface of the tatami mat, and the cutting depth H of the vertical surface of the tatami mat, can be precisely adjusted according to the thickness of the tatami mat base.

[0050] Furthermore, the tatami mat cutting device of the present invention is The horizontal bracket member has a horizontal indicator portion that shows the amount of horizontal movement of the tilting portion horizontal movement member, and a horizontal indicator groove portion formed in the horizontal direction. The tilting portion horizontal movement member has a horizontal pointer portion that can move within the horizontal indicator groove portion of the horizontal bracket member. The horizontal bracket member is configured to allow setting the amount of horizontal movement of the tilting horizontal movement member.

[0051] By configuring it in this way, the amount of horizontal movement of the tilting horizontal movement member can be accurately set relative to the horizontal bracket member by using a horizontal pointer that can move within the horizontal indicator groove of the horizontal bracket member.

[0052] As a result, the cutting angle α of the tatami mat with respect to the vertical surface of the tatami mat, and the cutting depth H of the vertical surface of the tatami mat, can be precisely adjusted according to the thickness of the tatami mat base.

[0053] Furthermore, the tatami mat cutting device of the present invention is The tilting horizontal moving member has a tilt angle indicator portion that shows the tilting angle of the tilting member, and a tilt angle indicator groove portion that is formed in an arc shape at the pivot center of the tilting member. The tilting member is formed with a tilting angle indicator portion that can move within the tilting angle indicator groove of the tilting portion horizontal movement member. The device is characterized in that it is configured to allow setting the tilting angle of the tilting member with respect to the horizontal moving member of the tilting section.

[0054] By configuring it in this way, the tilt angle of the tilting member can be accurately set relative to the tilting horizontal moving member by a tilt angle indicator that is movable within the tilt angle indicator groove of the tilting horizontal moving member.

[0055] As a result, the cutting angle α of the tatami mat with respect to the vertical surface of the tatami mat, and the cutting depth H of the vertical surface of the tatami mat, can be precisely adjusted according to the thickness of the tatami mat base.

[0056] Furthermore, the tatami mat cutting device of the present invention is When cutting thick tatami mats with a thickness of 30mm to 60mm, The cutting angle α is set so that the tatami mat base is cut at a cutting angle α1 of 8° relative to the vertical surface of the tatami mat base, The cutting depth H of the vertical surface of the tatami mat base is set to cut the tatami mat base with a cutting depth H1 of 13 mm. When cutting thin tatami mats with a thickness of 10mm to less than 30mm, The cutting angle α is set so that the tatami mat base is cut at a cutting angle α2 of 13° relative to the vertical surface of the tatami mat base, The cutting depth H of the vertical surface of the tatami mat is set to cut the tatami mat with a cutting depth H2 of 3 mm.

[0057] By configuring it in this way, when cutting thick tatami mats with a thickness of 30mm to 60mm, The cutting angle α allows the tatami mat to be cut at a cutting angle α1 of 8° relative to the vertical surface of the tatami mat, The cutting depth H on the vertical surface of the tatami mat base allows the tatami mat base to be cut with a cutting depth H1 of 13 mm.

[0058] Also, when cutting thin tatami mats with a thickness of 10mm to less than 30mm, The cutting angle α allows the tatami mat to be cut at a cutting angle α2 of 13° relative to the vertical surface of the tatami mat, The blade penetration depth H on the vertical surface of the tatami mat base allows the tatami mat base to be cut with a blade penetration depth H2 of 3 mm.

[0059] As a result, the precise cutting angle α and blade depth H can be easily set whether manufacturing thick or thin tatami mats.

[0060] Furthermore, the tatami mat cutting device of the present invention is The pivot point of the rotating blade, which tilts together with the tilting member, is above the cutting position X of the tatami mat, From the cutting surface of the aforementioned vertical cutting blade 、 It is characterized by being configured with a horizontal shift outward by a distance E.

[0061] By configuring it in this way, the pivot center Q1 of the tilting member's rotating blade is shifted horizontally outward by a distance E (for example, 0.2 mm) from the cutting surface of the vertical cutting blade, allowing for precise adjustment of the relationship between the cutting angle α and the cutting depth H so that it is 13 m at a cutting angle of 8 degrees and 3 mm at a cutting angle of 13 degrees. [Effects of the Invention]

[0062] According to the present invention, the pivot point of the tilting member is located at the lower end of the tilting member, above the cutting position X of the tatami mat base, and the pivot point of the tilting member is located in a position that does not interfere with the end of the floor-holding member on the side of the tatami mat base that is to be cut, which is positioned on the upper surface of the tatami mat base along the side of the tatami mat base that is to be cut when the tatami mat base is cut.

[0063] Therefore, even when the tilting member rotates to set the cutting angle α of the tatami mat with respect to the vertical surface of the tatami mat, it does not interfere with the end of the floor-holding member on the side of the tatami mat that is to be cut.

[0064] Furthermore, the cutting angle α of the tatami mat with respect to the vertical surface of the tatami mat, and the cutting depth H of the blade into the vertical surface of the tatami mat, can be adjusted according to the thickness of the tatami mat base.

[0065] Furthermore, the tilting member connected to the running member is configured to be movable horizontally relative to the side of the tatami mat to be cut. Therefore, by adjusting the tilting member in the horizontal direction, the cutting angle α of the tatami mat with respect to the vertical surface of the tatami mat, and the cutting depth H of the blade into the vertical surface of the tatami mat, can be adjusted steplessly and accurately according to the thickness of the tatami mat.

[0066] As a result, the cutting angle α and blade depth H can be easily and precisely set steplessly, whether manufacturing thick tatami mats, thin tatami mats, or tatami mats of non-conventional sizes. Moreover, it is possible to provide a tatami mat cutting device with a simple structure, no complicated processes required, requiring little effort or time, and reducing costs.

[0070] In Figures 1 and 2, reference numeral 10 indicates the tatami mat cutting device of the present invention.

[0071] The tatami mat cutting device 10 of the present invention includes a frame member 12 arranged along the cutting direction B of the side of the tatami mat 400 to be cut, as shown in Figures 1 to 3. As shown in Figures 1 to 3, the frame member 12 has a substantially L-shaped cross-section, with an upper guide rail 12a provided at its upper part and a lower guide rail 12b provided at its lower side end.

[0072] Furthermore, the frame member 12 is provided with a running member 14 that is movable along the cutting direction B. Specifically, the running member 14 has an upper guide groove 14a and a lower guide groove 14b formed therein, which fit into the upper guide rail 12a and lower guide rail 12b of the frame member 12, respectively.

[0073] As a result, the running member 14 is configured to be able to move along the cutting direction B of the frame member 12 by a drive mechanism (not shown).

[0074] Furthermore, as shown in Figures 1 to 3, the device is equipped with a tilting member 16 connected to the traveling member 14, which is configured to tilt relative to the traveling member 14 in a direction perpendicular to the cutting direction B (direction of arrow C) around the pivot center Q1, which is the actual axis.

[0075] The tilting member 16 is equipped with a rotating blade 18 that cuts the tatami mat base 400 at an inclined angle in cross-section.

[0076] As shown in Figures 1 to 3, a drive motor 20 is provided on the upper part of the tilting member 16, and a drive belt (not shown) stretched between the pulley 20a of the drive motor 20 and the pulley 18b of the rotation shaft 18a of the rotating blade 18 allows the rotating blade 18 to rotate at a constant speed.

[0077] Furthermore, as shown in Figures 1 to 8, the pivot center Q1 of the tilting member 16 is located at the lower end of the tilting member 16, above the cutting position X of the tatami mat floor 400. As shown in Figure 8, the pivot center Q1, which is the actual axis of the tilting member 16, is positioned so as not to interfere with the end portion 22a of the floor retaining member 22, which is positioned on the upper surface of the tatami mat 400 along the side of the tatami mat 400 to be cut, when the tatami mat 400 is cut. Furthermore, the pivot center Q1 of the tilting member 16 is positioned so as not to interfere with the side of the tatami mat floor 400 that is to be cut.

[0078] With this configuration, the pivot center Q1 of the tilting member 16 is located at the lower end of the tilting member 16 above the cutting position X of the tatami mat base 400, and the pivot center Q1 of the tilting member 16 is located in a position that does not interfere with the end portion 22a of the floor-holding member 22 that is positioned on the upper surface of the tatami mat base 400 along the side of the tatami mat base to be cut when the tatami mat base 400 is cut.

[0079] Therefore, even when the tilting member 16 rotates to set the cutting angle α of the tatami mat 400 with respect to the vertical surface 408 of the tatami mat 400, it does not interfere with the end portion 22a of the floor-holding member 22 on the side of the tatami mat that is to be cut.

[0080] Furthermore, the cutting angle α of the tatami mat base 400 relative to the vertical surface 408 of the tatami mat base 400, and the cutting depth H of the vertical surface 408 of the tatami mat base 400 can be adjusted according to the thickness of the tatami mat base 400.

[0081] As a result, when manufacturing thick tatami mats, thin tatami mats, or tatami mats of sizes other than conventional sizes, it is possible to easily set the precise cutting angle α and cutting depth H. Moreover, it is possible to provide a tatami mat cutting device 10 that has a simple structure, does not require complicated processes, requires little effort or time, and can reduce costs.

[0082] Furthermore, as shown in Figure 3, the tatami mat cutting device 10 of the present invention is positioned upstream of the rotating blade 18 in the cutting direction B of the tatami mat 400, and is connected to the traveling member 14, and is equipped with a vertical cutting blade 24 perpendicular to the cutting direction B.

[0083] As shown in Figure 3, the vertical cutting blade 24 has an adjustment groove 24a formed therein, and is configured so that its vertical position can be adjusted relative to the holding member 27 by fastening members 25 such as bolts and nuts.

[0084] With this configuration, the tilting member 16 tilts in a direction C perpendicular to the cutting direction B, around the pivot center Q1, and even when the rotating blade 18 provided on the tilting member 16 tilts around the pivot center Q1 at a cutting angle α of the tatami mat with respect to the vertical surface of the tatami mat, it is possible to maintain the vertical cutting blade 24 positioned upstream of the rotating blade 18 in a direction perpendicular to the cutting direction B.

[0085] In other words, as described above, the tatami mat cutting device 10 of the present invention, as shown in Figure 3, has a vertical cutting blade 24 with an upper and lower adjustment groove 24a formed therein, and is configured so that the vertical position of the vertical cutting blade 24 can be adjusted relative to the holding member 27 by fastening members 25 such as bolts and nuts.

[0086] Therefore, by configuring it in this way, it becomes possible to adjust the depth to which the upper part of the tatami mat base 400 is cut vertically in a direction perpendicular to the cutting direction by adjusting the vertical cutting blade 24 by moving it up and down.

[0087] Therefore, the vertical cutting blade 24, positioned upstream of the rotating blade 18, cuts the upper part of the tatami mat base 400 in a direction perpendicular to the cutting direction B. After that, the tilting member 16 is tilted around the pivot center Q1, and the rotating blade 18 provided on the tilting member 16 can accurately cut the tatami mat base 400 at the cutting angle α of the tatami mat base with respect to the vertical surface 408 of the tatami mat base.

[0088] Therefore, even when the tilting member 16 rotates to set the cutting angle α of the tatami mat with respect to the vertical surface of the tatami mat, the vertical cutting blade 24 does not interfere with the end portion 22a of the floor holding member 22 on the side of the tatami mat that is to be cut.

[0089] Furthermore, as shown in Figure 8, the tatami mat cutting device 10 of the present invention has a shape in which the end portion 22a of the floor holding member 22 on the side of the tatami mat to be cut has an inclined surface 22b on the cutting side so as not to interfere with the running member 14 and the tilting member 16.

[0090] With this configuration, the end portion 22a of the floor-holding member 22 on the side of the tatami mat that is to be cut has an inclined surface 22b on the cutting side, so that it does not interfere with the running member 14 and the tilting member 16.

[0091] Therefore, even when the tilting member 16 rotates to set the cutting angle α of the tatami mat 400 with respect to the vertical surface 408 of the tatami mat 400, the traveling member 14 and the tilting member 16 do not interfere with the end portion 22a of the floor-holding member 22 on the side of the tatami mat that is to be cut.

[0092] Furthermore, the tatami mat cutting device 10 of the present invention is configured such that the tilting member 16 connected to the traveling member 14 is movable horizontally with respect to the side of the tatami mat 400 to be cut.

[0093] With this configuration, the tilting member 16 connected to the running member 14 is configured to be able to move horizontally with respect to the side of the tatami mat floor 400 that is to be cut. Therefore, by moving the tilting member 16 horizontally with respect to the side of the tatami mat base 400 to be cut, the cutting angle α of the tatami mat base 400 with respect to the vertical surface 408 of the tatami mat base 400 and the cutting depth H of the vertical surface 408 of the tatami mat base 400 can be accurately adjusted according to the thickness of the tatami mat base 400.

[0094] Specifically, in the tatami mat cutting device 10 of the present invention, as shown in Figures 1 to 7, the traveling member 14 is equipped with a horizontal bracket member 26. Furthermore, the tilting portion horizontal movement member 28 is provided, which is connected to the horizontal bracket member 26 so as to be movable in the horizontal direction. Furthermore, the tilting member 16 is connected to the tilting horizontal movement member 28 so as to be able to tilt around the pivot center Q1.

[0095] By configuring the device in this way, the tilting horizontal movement member 28 can be adjusted to move horizontally relative to the horizontal bracket member 26, and the tilting member 16 can be adjusted to tilt around the pivot center Q1 relative to the tilting horizontal movement member 28. This allows for precise adjustment of the cutting angle α of the tatami mat 400 relative to the vertical surface 408 of the tatami mat 400, and the cutting depth H of the vertical surface 408 of the tatami mat 400, according to the thickness of the tatami mat 400.

[0096] Furthermore, in the tatami mat cutting device 10 of the present invention, as shown in Figures 4 and 7, the horizontal bracket member 26 has three horizontal guide grooves 30a to 30c that extend in the horizontal direction. Furthermore, as shown in Figures 5 and 7, the tilting horizontal movement member 28 is equipped with three horizontal movement fixing members 32a to 32c at positions corresponding to the horizontal guide grooves 30a to 30c of the horizontal bracket member 26.

[0097] Then, as shown in Figure 7, the horizontal movement fixing members 32a to 32c of the tilting section horizontal movement member 28 are slid and fixed into the horizontal guide grooves 30a to 30c of the horizontal bracket member 26. As a result, the tilting portion horizontal movement member 28 is configured to be movable and fixed in the horizontal direction D relative to the horizontal bracket member 26.

[0098] By configuring it in this way, the horizontal movement fixing members 32a to 32c of the tilting section horizontal movement member 28 are slidably fixed to the horizontal guide grooves 30a to 30c of the horizontal bracket member 26, thereby allowing the tilting section horizontal movement member 28 to be moved and fixed in the horizontal direction D relative to the horizontal bracket member 26.

[0099] As a result, the cutting angle α of the tatami mat base 400 relative to the vertical surface 408 of the tatami mat base 400, and the cutting depth H of the vertical surface 408 of the tatami mat base 400 can be precisely adjusted according to the thickness of the tatami mat base 400.

[0100] As shown in Figure 4, a viewing opening 43 is formed that is larger than the tilting groove 42a, corresponding to the tilting groove 42a. Furthermore, a viewing opening 45 is formed that is larger than the tilting groove 42b, corresponding to the tilting groove 42b.

[0101] Furthermore, in the tatami mat cutting device 10 of the present invention, as shown in Figures 4 and 7, the horizontal bracket member 26 has a horizontal indicator section 30 formed on it, which indicates the amount of horizontal movement of the tilting section horizontal movement member 28, for example, by a scale. Furthermore, the horizontal bracket member 26 has a horizontal indicator groove 32 formed in the horizontal direction.

[0102] Furthermore, as shown in Figures 5 and 7, the tilting horizontal movement member 28 has a horizontal pointer portion 34 that can move within the horizontal indicator groove portion 32 of the horizontal bracket member 26. This configuration allows the amount of horizontal movement of the tilting horizontal movement member to be set relative to the horizontal bracket member.

[0103] With this configuration, the amount of horizontal movement D of the tilting horizontal movement member 28 relative to the horizontal bracket member 26 can be accurately set by the horizontal pointer portion 34, which is movable within the horizontal indicator groove portion 32 of the horizontal bracket member 26.

[0104] As a result, the cutting angle α of the tatami mat base 400 relative to the vertical surface 408 of the tatami mat base 400, and the cutting depth H of the vertical surface 408 of the tatami mat base 400 can be precisely adjusted according to the thickness of the tatami mat base 400.

[0105] Furthermore, in the tatami mat cutting device 10 of the present invention, as shown in Figures 5 and 7, the tilting horizontal moving member 28 has a tilting angle indicator 36 formed on it, which indicates the tilting angle of the tilting member 16, for example, a scale. Furthermore, the tilting horizontal movement member 28 is equipped with a tilt angle indicator groove 38 formed in an arc shape at the pivot center Q1 of the tilting member 16. Furthermore, the tilting member 16 has a tilting angle indicator part 40 that can move within the tilting angle indicator groove part 38 of the tilting part horizontal movement member 28. This configuration allows the tilting angle of the tilting member 16 to be set relative to the tilting horizontal movement member 28.

[0106] Furthermore, the horizontal bracket member 26 has a viewing opening 11 that allows the tilt angle indicator groove 38 and the tilt angle pointer 40 to be viewed from the outside.

[0107] With this configuration, the tilt angle indicator 40, which is movable within the tilt angle indicator groove 38 of the tilt horizontal movement member 28, allows for the precise setting of the tilt angle of the tilt member 16 relative to the tilt horizontal movement member 28.

[0108] As a result, the cutting angle α of the tatami mat base 400 relative to the vertical surface 408 of the tatami mat base 400, and the cutting depth H of the vertical surface of the tatami mat base can be precisely adjusted according to the thickness of the tatami mat base 400.

[0109] In the tatami mat cutting device 10 of the present invention, as shown in Figures 5 and 7, the tilting horizontal moving member 28 has two tilting movement grooves 42a to 42b formed in an arc shape at the pivot center Q1 of the tilting member 16.

[0110] Furthermore, the tilting member 16 has two tilting fixing members 44a to 44b, which are movable within the tilting movement grooves 42a to 42b of the tilting horizontal movement member 28, and are made of, for example, screws.

[0111] This configuration allows the tilting member 16 to be fixed at a predetermined angle by fixing the tilting fixing members 44a to 44b of the tilting horizontal movement member 28 within the tilting movement grooves 42a to 42b of the tilting horizontal movement member 28.

[0112] As shown in Figure 8, the tatami mat cutting device 10 of the present invention, configured in this way, cuts the tatami mat 400 in a cross-sectional view with a vertical surface 408 on the upper side of the tatami mat 400 and an inclined surface 412 on the lower side, in order to make it easier to lay the tatami mats when cutting on the frame 102 side.

[0113] In this type of cutting, the tatami mat cutting device 10 of the present invention, as shown in Figure 8(A), when cutting thick tatami mats with a thickness of 30 mm to 60 mm, The cutting angle α is set so that the tatami mat base 400 is cut at a cutting angle α1 of 8° relative to the vertical surface 408 of the tatami mat base 400, The cutting depth H of the vertical surface 408 of the tatami mat base 400 is set to cut the tatami mat base with a cutting depth H1 of 13 mm. When cutting thin tatami mats with a thickness of 10mm to less than 30mm, The cutting angle α is set so that the tatami mat base 400 is cut at a cutting angle α2 of 13° relative to the vertical surface 408 of the tatami mat base 400, The cutting depth H of the vertical surface 408 of the tatami mat base 400 is set to cut the tatami mat base with a cutting depth H2 of 3 mm.

[0114] By configuring it in this way, when cutting thick tatami mats with a thickness of 30mm to 60mm, The cutting angle α allows the tatami mat base to be cut at a cutting angle α1 of 8° relative to the vertical surface 408 of the tatami mat base 400, The cutting depth H of the vertical surface 408 of the tatami mat base 400 allows the tatami mat base to be cut with a cutting depth H1 of 13 mm.

[0115] Also, when cutting thin tatami mats with a thickness of 10mm to less than 30mm, The cutting angle α allows the tatami mat to be cut at a cutting angle α2 of 13° relative to the vertical surface of the tatami mat, The cutting depth H of the vertical surface 408 of the tatami mat base 400 allows the tatami mat base to be cut with a cutting depth H2 of 3 mm.

[0116] As a result, the precise cutting angle α and blade depth H can be easily set whether manufacturing thick or thin tatami mats.

[0117] In Figure 8(A), distance E indicates a horizontal offset of, for example, 0.2 mm from the cutting surface of the vertical cutting blade 24 to the pivot center Q1 of the tilting member 16. In other words, the pivot point Q1 of the rotating blade 18 of the tilting member 16 is located outward (to the right in Figure 8(A)) from the cutting surface of the vertical cutting blade 24.

[0118] In this way, by shifting the pivot center Q1 of the rotary blade 18 horizontally outward by a distance E (for example, 0.2 mm) from the cutting surface of the vertical cutting blade 24, the relationship between the cutting angle α and the cutting depth H can be precisely adjusted so that it is 13 m at a cutting angle of 8 degrees and 3 mm at a cutting angle of 13 degrees.

[0119] Furthermore, by adjusting the tilting horizontal movement member 28 in the horizontal direction relative to the horizontal bracket member 26, the tilting member 16 (rotating blade 18) can be adjusted to move horizontally further outward (to the right in Figure 8(A)) than in Figure 8(A), as shown in Figure 8(B). Furthermore, the cutting angle α can be adjusted by tilting the tilting member 16 around the pivot center Q1 relative to the tilting horizontal moving member 28.

[0120] This allows for stepless and precise adjustment of the cutting angle α of the tatami mat base 400 relative to the vertical surface 408 of the tatami mat base 400, and the cutting depth H of the vertical surface 408 of the tatami mat base 400, according to the thickness of the tatami mat base 400.

[0121] In the tatami mat cutting device 10 of Embodiment 1 configured in this way, the pivot center Q1 of the tilting member 16 is located at the lower end of the tilting member 16 above the cutting position X of the tatami mat 400, and the pivot center Q1 of the tilting member 16 is located in a position that does not interfere with the end portion 22a of the floor holding member 22 that is positioned on the upper surface of the tatami mat 400 along the side of the tatami mat 400 to be cut when cutting the tatami mat 400.

[0122] Therefore, even when the tilting member 16 rotates to set the cutting angle α of the tatami mat 400 with respect to the vertical surface 408 of the tatami mat 400, it does not interfere with the end portion 22a of the floor-holding member 22 on the side of the tatami mat that is to be cut.

[0123] Furthermore, depending on the thickness of the tatami mat base 400, the cutting angle α of the tatami mat base 400 with respect to the vertical surface 408 of the tatami mat base 400 and the cutting depth H of the vertical surface of the tatami mat base can be adjusted.

[0124] Furthermore, the tilting member 16 connected to the running member 14 is configured to be movable horizontally relative to the side of the tatami mat floor 400 to be cut, as shown in Figure 8(B). Therefore, by moving and adjusting the tilting member 16 in the horizontal direction, the cutting angle α of the tatami mat 400 with respect to the vertical surface 408 of the tatami mat 400, and the cutting depth H of the vertical surface 408 of the tatami mat 400 can be adjusted steplessly and accurately according to the thickness of the tatami mat 400.

[0125] As a result, the cutting angle α and blade depth H can be easily and precisely set steplessly, whether manufacturing thick tatami mats, thin tatami mats, or tatami mats of non-conventional sizes. Moreover, it is possible to provide a tatami mat cutting device 10 that has a simple structure, does not require complicated processes, requires little effort or time, and can reduce costs. (Example 2)

[0126] Figure 9 is a front view of the tatami mat cutting device 10 of another embodiment of the present invention, showing a case where a thick tatami mat is cut at a cutting angle α1 of 8° relative to the vertical surface 408 of the tatami mat base 400. Figure 10 is a front view of the tatami mat cutting device 10 of another embodiment of the present invention, showing a case where a thin tatami mat is cut at a cutting angle α2 of 13° relative to the vertical surface 408 of the tatami mat base 400. Figure 11 is a side view of direction A in Figures 9 and 10. Figure 12 Figure 13 is an exploded view of the horizontal bracket member 26 of the running member 14 of the tatami mat cutting device 10 of the present invention, Figure 14 is an exploded view illustrating the assembled state of the horizontal bracket member 26 and the tilting member 16 of the running member 14 of the tatami mat cutting device 10 of the present invention, and Figure 15 is a partially enlarged view illustrating the general case of cutting a thick tatami mat and cutting a thin tatami mat using the tatami mat cutting device 10 of the present invention.

[0127] The tatami mat cutting device 10 in this embodiment has basically the same configuration as the tatami mat cutting device 10 in Embodiment 1 shown in Figures 1 to 8. The same reference numerals are used for the same components, and their detailed descriptions are omitted.

[0128] In the tatami mat cutting device 10 of Embodiment 1 shown in Figures 1 to 8, the tilting member 16 connected to the traveling member 14 is configured to be movable horizontally with respect to the side of the tatami mat 400 to be cut. In contrast, in the tatami mat cutting device 10 of this embodiment, as shown in Figures 9 to 15, the tilting member 16 connected to the traveling member 14 is structured in such a way that it cannot move horizontally relative to the traveling member 14, but can only rotate in the tilting direction.

[0129] Therefore, in this embodiment of the tatami mat cutting device 10, the tilting horizontal moving member 28 is omitted.

[0130] In the tatami mat cutting device 10 of this embodiment, the horizontal bracket member 26 of the traveling member 14 has a single tilting movement groove 46 formed in an arc shape at the pivot center Q1 of the tilting member 16, as shown in Figures 12 to 14.

[0131] Furthermore, the tilting member 16 has a tilting fixing member 48 formed on it, at a position corresponding to the tilting movement groove 46 of the horizontal bracket member 26, which is movable within the tilting movement groove 46 of the horizontal bracket member 26 and is made of, for example, a screw.

[0132] This configuration allows the tilting member 16 to be fixed at a predetermined angle by fixing the tilting fixing member 48 of the tilting member 16 within the tilting movement groove 46 of the horizontal bracket member 26.

[0133] In the tatami mat cutting device 10 configured in this way, as shown in Figures 9 to 15, the pivot center Q1 of the tilting member 16 is located at the lower end of the tilting member 16, above the cutting position X of the tatami mat 400. As shown in Figure 15, the pivot center Q1, which is the actual axis of the tilting member 16, is positioned so as not to interfere with the end portion 22a of the floor retaining member 22, which is positioned on the upper surface of the tatami mat 400 along the side of the tatami mat 400 to be cut, when the tatami mat 400 is cut. Furthermore, the pivot center Q1 of the tilting member 16 is positioned so as not to interfere with the side of the tatami mat floor 400 that is to be cut.

[0134] With this configuration, the pivot center Q1 of the tilting member 16 is located at the lower end of the tilting member 16 above the cutting position X of the tatami mat base 400, and the pivot center Q1 of the tilting member 16 is located in a position that does not interfere with the end portion 22a of the floor-holding member 22 that is positioned on the upper surface of the tatami mat base 400 along the side of the tatami mat base to be cut when the tatami mat base 400 is cut.

[0135] Therefore, even when the tilting member 16 rotates to set the cutting angle α of the tatami mat 400 with respect to the vertical surface 408 of the tatami mat 400, it does not interfere with the end portion 22a of the floor-holding member 22 on the side of the tatami mat that is to be cut.

[0136] Furthermore, the cutting angle α of the tatami mat base 400 relative to the vertical surface 408 of the tatami mat base 400, and the cutting depth H of the vertical surface 408 of the tatami mat base 400 can be adjusted according to the thickness of the tatami mat base 400.

[0137] As a result, when manufacturing thick tatami mats, thin tatami mats, or tatami mats of sizes other than conventional sizes, it is possible to easily set the precise cutting angle α and cutting depth H. Moreover, it is possible to provide a tatami mat cutting device 10 that has a simple structure, does not require complicated processes, requires little effort or time, and can reduce costs.

[0138] While preferred embodiments of the present invention have been described above, the present invention is not limited thereto. For example, in the above embodiment, the tatami mat cutting device 10 is configured to have a movable mechanism that can move in the cutting direction B of the tatami mat 400. However, it is also possible to make the movable mechanism immovable (fixed) and cut the tatami mat 400 by moving the mounting table on which it is placed. Various modifications are possible without departing from the object of the present invention. [Industrial applicability]

[0139] The present invention can be applied, for example, to a cutting device for tatami mat bases used in tatami mats, such as borderless tatami mats and bordered tatami mats.

[0140] More specifically, the present invention can be applied to a tatami mat cutting device for cutting a tatami mat in cross-section, with the upper part cut with a vertical plane (cutting depth H) and the lower part cut with an inclined plane (cutting angle) that is inclined inward.
