Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutting device for a half tatami size tatami mat used for edgeless tatami mats for half tatami mats, for example.

Conventionally, for example, half tatami mats such as rimless square tatami mats for half tatami mats such as Ryukyu tatami mats have recently come to be widely used from the standpoint of interior decoration.

When manufacturing half tatami mats such as rimless tatami mats for such half tatami mats, the upper front side, lower front side, and frame of the tatami floor are cut by a tatami floor cutting device before the tatami surface is sewn or pasted. The sides are cut to size to match the dimensions of the room in which they will be laid.

By the way, as a conventional tatami floor cutting apparatus, for example, Patent Document 1 (Japanese Unexamined Patent Publication No. 9-294886) discloses a tatami manufacturing system.

Among them, there is a frame cutting machine that cuts the frame part of the tatami floor, a tatami facing machine that overlaps the tatami mat on the tatami floor and sews both sides of the tatami mat, and a flat stitching machine that performs flat stitching and cutting of the upper front and lower front. machine is disclosed.

This patent document 2 (Japanese Laid-Open Patent Publication No. 9-250229) discloses a mechanism for trimming the frame side of tatami mats and cutting the tatami mats to a predetermined size.

Further, Patent Document 3 (Japanese Patent Application Laid-Open No. 4-216901) discloses a plate-like body cutting device that turns a rectangular plate-like body precisely 90° and cuts the four sides of the rectangular plate-like body. It is

That is, in Patent Document 3, a pair of cutting tools facing each other in the width direction are provided so as to move forward and backward in the width direction, respectively, with the central portion of a linear transport rail extending in the front-rear direction sandwiched therebetween.

A plate-like object transport vehicle that reciprocates on the transfer rail is provided with a swivel support that vertically holds the central portion of the plate-like object and rotates horizontally by 90 degrees.

JP-A-9-294886 JP-A-9-250229 JP-A-4-216901

By the way, when using the tatami manufacturing system disclosed in Patent Document 1 to cut the four sides of a square tatami mat for a semi-tatami mat, an operator turns the tatami mat by 90° and uses the frame cutting machine. A process of cutting twice is required.

Also, in Patent Document 2, when cutting the four sides of a tatami mat for a half tatami mat, the worker needs to turn the tatami mat 90 degrees and cut it twice with a frame cutting machine.

Therefore, in both cases of Patent Document 1 and Patent Document 2, it is necessary to manually turn the tatami floor, which is troublesome and costly.

By the way, as shown in FIG. 25, the threshold of a room is not necessarily 100% square or rectangular. should be a right angle.

In this case, as shown in FIG. 25, since the tatami mat is finished and laid out by smoothing the lower front side so that it fits exactly along the threshold, the shape of the tatami mat in plan view is different from the side of the upper front side and the lower side that face each other. If the front side edge is peculiar, it will not be perfectly parallel.

In this case, the straightness of each side of the unfinished tatami floor is unstable, so that, for example, two cutting operations as shown in FIG. 6 are required.

For example, as shown in FIG. 6A, a case of cutting a finished tatami floor 300 as indicated by a dotted line from an unfinished tatami floor 200 as indicated by a solid line will be described.

That is, as shown in FIG. 6A, one frame side D2 is perpendicular to the upper front side D0 of the finished tatami floor 300 (no peculiarity), and the other frame side D3 has a peculiarity. This shows the case where the front side D0 is not perpendicular to the frame side D3.

In this case, after cutting the frame sides D2 and D3 in the first cutting, the tatami mat is turned clockwise by 90° as indicated by the arrow in FIG. Cut the front side D1.

However, in both the cases of Patent Document 1 and Patent Document 2, the worker is responsible for at least two sides (upper front side) sandwiching the right angle of the unfinished tatami mat (in the case of FIG. 6, the upper front side D0 and the frame side D2). ), it is necessary to turn the tatami floor 90 degrees, but there is a possibility that the turning direction is wrong.

Furthermore, Patent Document 1 discloses a plate-like body cutting device that turns a rectangular plate-like body precisely 90° and cuts the four sides of the rectangular plate-like body disclosed in Patent Document 3. If it is applied to a tatami mat manufacturing system and cut by turning 90 degrees, the installation space of the device becomes large, and a precise and complicated mechanism is required for turning 90 degrees accurately. The larger the size, the higher the cost.

The tatami floor 200 has tatami floor seams F formed at regular intervals. It overlaps F, cuts the sewing thread, and overlaps the sewing hole.

In addition, as shown in FIG. 25, for example, in the case of a square tatami floor with no peculiarity, such as in the central part of the room, the same problem occurs in the lower front cutting line on the lower front side. .

That is, for example, as shown in FIG. 26(A), the tatami mat 200 before cutting is arranged such that the upper front side D0 of the tatami mat 300 after cutting does not overlap the seams F of the tatami mat. is positioned at a distance Z from the end of the upper front side 202 of the .

In this case, as shown in FIG. 26A, the cutting line on the lower front side D1 of the tatami floor 300 after cutting does not overlap the seams F of the tatami floor.

However, depending on the dimensions of the tatami floor 300 after cutting, the cutting line on the lower front side D1 of the tatami floor 300 after cutting may not overlap the seam F of the tatami floor, as surrounded by an ellipse Q in FIG. 26(B). Sometimes I end up

As a result, the surfaces and side surfaces of the upper front side D0 and the lower front side D1 have jagged unevenness, and when the tatami facing is sewn or attached to the surface of the finished tatami floor, the upper front side D0 and the lower front side D1 become difficult. The tatami mats become uneven and look bad, the straightness of the upper front side deteriorates, and when the tatami mats are laid all over, there will be gaps.

In view of the current situation, the present invention provides a tatami mat that is cut by a tatami mat cutting device before the tatami surface is sewn or pasted when a half tatami mat such as a rimless tatami mat for a half tatami mat is manufactured. To provide a tatami floor cutting device capable of cutting the upper front side, the lower front side and the stile side of a tatami mat into predetermined dimensions matching the dimensions of a room to be laid.

In addition, the present invention eliminates the need for complicated turning work of tatami mats by hand, reduces the work process, saves labor and cost, eliminates the possibility of making a mistake in the turning direction, and ensures accurate finishing dimensions and equipment. To provide a tatami floor cutting device which does not increase in size.

For convenience of explanation, the control of the control device 60 is shown as steps in the following.

As an example, in the case of cutting the tatami mat at part J shown in FIG. 25, as shown in FIG. A case of cutting the finished tatami mat 300 as shown will be described.

That is, as shown in FIG. 6A, one frame side D2 is perpendicular to the upper front side D0 of the finished tatami floor 300 (no peculiarity), and the other frame side D3 has a peculiarity. This shows the case where the front side D0 is not perpendicular to the frame side D3.

Then, in step S1, first, a dimension input step is performed in which numerical values such as the finished dimensions of the finished tatami floor 300 are input to the operation input screen constituting the input device of the control device 60, and the start button is pressed. .

In this case, of course, numerical values such as finishing dimensions may be automatically input from a mobile terminal such as a smartphone or a personal computer using a communication means such as LAN or wireless LAN. I don't mind.

Next, in step S2, based on the information such as the finished dimensions of the finished tatami floor 300 input in step S1, as shown in FIG. A cutting position determining step for determining the cutting position of the tatami mat after cutting is performed on the tatami mat before cutting in accordance with the dimensions.
That is, although not shown, the control device 60 includes an information processing device and a storage device that stores the dimensions of the tatami mat after cutting input by the input device. A cutting position determination step for determining the cutting position of the tatami floor after cutting is performed on the tatami floor before cutting according to the dimensions of the tatami floor after cutting input by the input device.

That is, in the cutting position determining step, as shown in FIG. 7, the upper front cutting position A is set to the upper front side of the tatami mat 200 before cutting according to the dimensions of the tatami mat after cutting input in the dimension inputting step. The upper front cutting line is set at a position spaced apart from the edge 202 by a distance X1 and away from the seam F of the tatami mat 200 before cutting.

Further, as shown in FIG. 7, in the cutting position determination step, the lower front cutting position B is set above the tatami floor 200 before cutting according to the dimensions of the tatami floor 300 after cutting input in the dimension input step. It is set at a position separated by the longest distance X2 from the front edge 202 and the shortest distance X3 from the upper front edge 202 of the tatami mat 200 before cutting and out of the seams of the tatami mat.

As shown in FIG. 8, when the lower front side D1 of the finished tatami floor 300 has no peculiarities, the longest distance X2=the shortest distance X3.

Also, in the case of this embodiment, since the tatami floor of FIG. The shortest distance X3 from is located at D2 (frame side), but depending on the shape of various tatami mats, the longest distance X2 can be set on one frame side, and the shortest distance X3 can be set on the other frame side. Of course.

As shown in FIG. 7, the position of one frame side D2 (left side in FIG. 7) of the tatami mat 300 after cutting is from the frame side 206 which is the left end of the tatami mat 200 before cutting. It is set to a distance separated by a distance X4.

In this case, as will be described later, in step S5, the worker inserts the uncut (unfinished) tatami mat 200 from the front side of the cutting device main body 12 of the tatami mat cutting device 10. These dimensions are determined in the tatami floor setting step.

Next, in step S3, as shown in FIG. 9, a stopper position adjusting step of adjusting the position of the stopper 16 according to the cutting position of the tatami mat 300 after cutting determined in the cutting position determining step of step S2. is done.

That is, in the stopper position adjusting step of step S3, the position of the stopper 16 is determined according to the distance X1 determined in the cutting position determining step of step S2.

Specifically, as indicated by the dotted line in FIG. 9, a reference value for the distance X1 is set in advance, and the stopper is moved by the deviation α from this reference value.

Next, in step S4, a cutting unit moving step is performed to move the pair of left and right cutting units 32 according to the width of the inserted tatami mat 200 on the basis of the input data input in step S1. .

Then, in step S5, a tatami floor setting step is performed in which the worker inserts the uncut (unfinished) tatami floor 200 from the front side of the cutting device main body 12 of the tatami floor cutting device 10 .

In this case, it is of course possible to perform the tatami floor setting step immediately after the start.

Then, in step S6, as shown in FIGS. 4 and 10, the upper front side 202 of the inserted tatami mat 200 is pressed against the stopper 16 by the pressing member 30. A first pressing step is performed to push the lower front side 204, which is the front side (front side) of the tatami mat.

That is, the pressing member 30 of the pressing device 24 is tilted from the retracted position (dotted line in FIG. 4) to the pressing position (solid line in FIG. 4) by the expansion and contraction of the drive cylinder 26 .

Then, the pressing member 30 pushes the lower front side 204, which is the front side of the tatami mat 200, so that the upper front side 202, which is the rear side, of the inserted tatami mat 200 contacts the stopper 16 (FIG. 4). (dotted line)), the tatami floor 200 is pushed in by moving backward in the direction of arrow C in FIGS. 4 and 10 .

Next, in step S7, the tatami floor pressing member 38 of the cutting unit 32 is lowered by the cylinder drive mechanism 36 against the tatami floor 200 placed at the predetermined position in the first pressing step of step S6, A first tatami floor pressing step for pressing the tatami floor 200 is performed.

Then, in step S8, as indicated by the arrow H in FIG. 11, the frame sides 206 and 208, which are the left and right ends of the tatami mat 200 pressed in the first tatami mat pressing step of step S7, are cut by a cutting unit. A first cutting step is performed by cutting with 32 cutting blades 46 .

1 and 3, a cutting blade 46 is rotated by a drive motor 44 along a guide rail 40 extending in the longitudinal direction. , and moves backward (arrow H in FIG. 11) to cut the frame sides 206 and 208, which are the left and right ends of the tatami floor 200. As shown in FIG.

As a result, as shown in FIG. 6A, one frame side D2 that is perpendicular to the upper front side D0 of the finished tatami floor 300 and the other frame side D3 that has a wavy shape are formed.

Also, as shown in FIG. 12, in step S9, from the upper front side 202, which is the rear side of the tatami mat 200 inserted during the first cutting step of step S8, the front side of the tatami mat 200 is cut. A first width measurement step is performed to measure the distance T1 of the lower front side 204 .

That is, for example, a detection sensor such as an optical sensor (not shown) is used to detect whether or not the end surface of the inserted tatami mat 200 is sandwiched between the stopper 16 and the pressing member 30, and the amount of movement of the pressing member 30 is detected. Based on this, by measuring the distance between the stopper 16 and the pressing member 30, the distance T1 from the upper front side 202, which is the rear side of the tatami floor 200, to the lower front side 204, which is the front side of the tatami floor 200, is measured. (See FIG. 12).

Next, in step S10, the tatami floor pressing members of the cutting unit 32 are applied to the tatami floor 200 from which the frame sides 206 and 208, which are the left and right ends of the tatami floor 200, have been cut in the first cutting step of step S8. 38 rises to perform the first tatami floor pressing release step for releasing the tatami floor pressing.

Then, as shown in FIG. 13, in step S11, the turning table 48 moves the tatami floor 200 onto the tatami floor 200, the pressure of which has been released in the first tatami floor pressure release step in step S10. A tatami floor turning step is performed in which the tatami floor is moved upward from the lower side of and turned 90° with the tatami floor 200 placed thereon to turn the tatami floor 90°.

In this case, as shown in FIG. 13, the center P of the swivel table 48 is measured from the upper front side 202, which is the rear side of the inserted tatami mat 200 measured in the width measurement step of step S10). It is moved in advance so as to be located at a substantially middle position (a position of T1/2) of a distance T1 on the lower front side 204, which is the front side of 200. As shown in FIG.

In this case, under the control of the control device 60, based on the input data input in step S1, according to the position where the angle between the upper front side 202 of the inserted tatami mat 200 and the frame side is a right angle, step S11 is performed. In the tatami floor turning step, the turning direction for turning the tatami floor by 90° is determined.

That is, in this embodiment, as shown in FIG. 6A, one frame side D2 is perpendicular to the upper front side D0 of the finished tatami floor 300, and the other frame side D3 Because of the peculiarity, as indicated by arrow G in FIG. Pivoted to position on the right side.

In this state, one frame side D2 of the finished tatami floor 300 is positioned on the stopper 16 side, as shown in FIGS. 6(B) and 14 .

Therefore, the angle formed between the upper front side D0 of the finished tatami floor 300 (that is, the upper front side 202 of the tatami floor 200) and the frame side D2 located on the stopper 16 side is a right angle.

Next, in step S12, a stopper origin return step is performed.

That is, in the stopper origin return step of step S12, as indicated by the dotted line in FIG. steps to be taken.

In the stopper origin return step, the stopper 16 is moved to its original position as indicated by the arrow in FIG.

Of course, in the stopper position adjustment step of step S3, the preset reference value of the distance X1 is equal to the distance X1 determined in the cutting position determination step of step S2, and the stopper is moved by the deviation α. If not, it is not performed and it is configured to proceed to the next step S14.

In this state, in step S13, as shown in FIG. 16, the arm members 54 are moved from the left and right to the left and right ends of the tatami floor 200, which has been turned 90 degrees in the tatami floor turning step of step S11. The upper front side 202 of the tatami floor 200 located on the right side and the lower front side 204 of the tatami floor 200 located on the left side are in contact with each other, and the upper front side 202 and the lower front side 204 that are the left and right ends of the tatami floor 200 are predetermined.

As a result, the sewing thread is not cut and does not overlap the sewing hole.

In addition, when the tatami facing is sewn or attached to the surface of the tatami floor on which the tatami facing is finished, the upper front side does not become uneven, and the appearance is good, and the straightness of the upper front side is good. Also, there are no gaps.

As shown in FIG. 19, when the arm member 54 (in this embodiment, the right arm member 54) on the side of the upper front end 202 of the tatami mat 200 is actuated, the arm member 54 is adjusted. The contact member 56 is put in a stretched state.
After that, while the other arm member 54 (in this embodiment, the left arm member 54) on which the lower front side 204 of the tatami floor 200 is located is in contact with the lower front side 204 of the tatami floor 200, the left arm member 54 The adjustment abutment member 56 is extended to move the lower front side 204, which is the other end of the tatami floor 200. As shown in FIG.

As shown in FIG. 19, in this cutting position adjustment step, the left arm member 54 is once rotated to release it from the state of contact with the lower front side 204 of the tatami floor 200 . .

Then, the other cutting unit 32 where the lower front side 204 of the tatami mat 200 is located is moved to the lower front side cutting position B according to the size input in the size input step S1.

In this state, as shown in FIG. 20, in step S13, the upper front side 202 and the lower front side 204, which are the left and right ends of the tatami mat 200, are moved to predetermined cutting positions in the cutting position adjusting step. The front side of the tatami floor 200 is pushed by the pressing member 30 so that the frame side 206 (one frame side D2), which is the rear side of the tatami floor 200, is in contact with the stopper 16. A second pressing step is performed to push the frame side (the other frame side D2) (FIG. 6(B)).

In this case, as shown in FIG. 20, based on the data input in advance, according to the inclination angle (habit) of the frame side D3 (the frame side 208 of the tatami floor 200) that contacts the pressing member 30, The pressing member 30 may be inclined so as to come into contact therewith.

Further, in step S15, as shown in FIG. 21, the tatami floor pressing member 38 of the cutting unit 32 is lowered with respect to the tatami floor 200 placed at the predetermined position in the second pressing step of step S14, A second tatami floor pressing step for pressing the tatami floor 200 is performed.

Next, in step S16, as indicated by arrow H in FIG. 21, the upper front side 202 and the lower front side 204, which are the left and right ends of the tatami floor 200 held down in the second tatami floor holding step of step S16, are pressed. , a second cutting step of cutting by the cutting blades 46 of the cutting unit 32 is performed.

As a result, as shown in FIG. 22, the upper front side 202 and the lower front side 204, which are the left and right ends of the tatami floor 200, are cut as shown in FIG. An upper front side D0 (that is, the upper front side 202 of the tatami floor 200) and a lower front side D1 of the finished tatami floor 300 (that is, the lower front side 204 of the tatami floor 200) are formed.

The above steps are repeated when the finished tatami mat 300 is taken out and another new tatami mat 200 is cut.

According to the tatami floor cutting apparatus 10 of the present invention configured as described above, according to the dimensions of the tatami floor 300 after cutting input in the dimension input step of step S1 for inputting the dimensions of the tatami floor 300 after cutting, Then, in the cutting position determination step of step S2, the cutting position of the tatami floor 300 after cutting is determined with respect to the tatami floor 200 before cutting.

Specifically, the upper front cutting position A is a position separated by a distance X1 from the upper front end 202 of the tatami floor 200 before cutting, and the upper front cutting line is the seam F of the tatami floor 200 before cutting. is set to a position away from

In this way, the position of the stopper may be fixed regardless of the cutting position of the tatami floor after cutting determined in the cutting position determining step.

That is, the position of the stopper 16 is fixed in advance, and accordingly, the upper front cutting position A is located at a distance X1 from the upper front end before cutting, and is separated from the seams of the tatami mat. The upper front cutting line does not overlap the seams F of the tatami floor.

As a result, the sewing thread is not cut, it does not overlap with the sewing holes, and when the tatami facing is sewn or attached to the surface of the finished tatami floor, the upper front side will not be uneven. It looks good, has good linearity on the upper front side, and does not leave any gaps when the tatami mats are laid out.

Even in this case, the cutting position of the tatami floor after cutting can be determined so that the cutting line on the lower front side D1 of the tatami floor 300 after cutting does not overlap the seam F of the tatami floor.

In addition, the lower front cutting position B is the position separated from the upper front edge before cutting by the longest distance X2 and the shortest distance X3 from the upper front edge before cutting, and away from the seam of the tatami mat. and the lower front cutting line does not overlap the seams F of the tatami floor.
