DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tatami mat straightening device, and more particularly, to input room size data obtained by a room size measuring device through a communication line and process the size data to obtain a tatami mat. It is configured to take a habit.

[0002]

2. Description of the Related Art When laying a tatami mat in a room, prepare a tatami mat floor that is slightly larger than the finished size, cut the side edge (upper front) on the side that contacts the next tatami mat into a straight line, and As a reference, cut the stile on the side that touches the next tatami at a right angle to the front,
The side edge (bottom front) on the side that contacts the sill and the stile on the side that contacts the sill are each cut into a bent shape or an angle according to the shape of the sill.

For example, as shown in FIG. 4, a tatami floor of a rectangle ABCD consisting of upper front (AD), lower front (BC), left stile (AB) and right stile (CD) shown by dotted lines is used as a reference,
When three sides other than the upper one touch the sill, deviations Xa, Xb, Xc, Xd in the length direction of points Aa, Ba, Ca, Da corresponding to the sill
And the widthwise deviations Yb, Ye, Yc at one end B, the center E, and the other end C in the lower front are measured, respectively, and the pentagons (Aa, Ba, Ea, Ca, Da) shown by the solid line are measured. Tatami floors are designed. When the right and left stiles contact another tatami, the deviations Xa, Xb and Xc, Xd are set to zero.

A conventional tatami matting device for automatically cutting the right and left stiles and lower fronts of tatami mats as designed has been proposed (see Japanese Patent Publication No. 60-55662).

As shown in FIG. 5, the conventional tatami mat shaving device comprises a stile cutting machine 19, a flat stab machine 20, and a control device 21.

The stile cutting machine 19 includes a pair of parallel rails 19
a and a pair of cutting boards 19b, and these two cutting boards
Both ends of 19b are independently slid along a pair of parallel rails 19a by a feed screw driven by a motor, so that the two cutting boards 19b can be set at desired positions and directions. .

The flat pricking machine 20 is provided with a tatami mat transfer table 20a, a stationary upper front sewing machine main body 20b, and a lower front sewing machine main body 20c, and linearly moves in the direction of arrow R by the tatami mat transfer table 20a. With respect to the tatami floor, the upper front sewing machine main body 20b sews the hem cloth and the underneath sewn on the tatami mat with sewing machine needles to perform a flat stab at the upper and lower sides, and at the same time, it is controlled by the control device 21. This is a device for performing flat stab and cutting of a tatami floor at the lower front by the lower front sewing machine main body 20c which moves in the width direction Q.

The control device 21 includes a terminal device for a sword cutting machine.
22 and a flat-piercing machine terminal device 23 are connected, and both have a built-in microcomputer. The control device 21 includes a large number (for example, 200 sheets) of tatami floors, a deviation Xa in the length direction of the four corners from a standard size tatami floor,
Deviations Yb, Ye, Yc in the width direction of Xb, Xc, Xd and the three points below
It has a memory for storing each.

As shown in FIG. 6, the controller 21 draws a key for inputting each deviation Xa, Xb, Xc, Xd and Yb, Ye, Yc, and a rectangular frame 24 representing a tatami floor. Input instruction lamps 24a, 24b, 24c, 24d provided at the four corners
And the indicators 25a, 25b, 25c, which are installed close to these lamps and display the deviations Xa, Xb, Xc, Xd in the length direction,
25d, lower front input instruction lamps 26b, 26e, 26c, and the lamps are installed close to these lamps, and the deviation Yb, Y in the width direction is provided.
Indicators 27b, 27e, 27c for displaying e and Yc, a tatami number input instruction lamp 29, and a tatami number indicator 28 for displaying the tatami number
And a panel on which a switch 30 for selecting whether the size of the tatami mat is a single tatami mat or a half tatami mat and lamps 30 and 31 for displaying the switching state of the switch 30 are arranged.

When the control device 21 is activated, the respective lamps are turned on one by one in the input order. Therefore, when the tatami number and the deviation are input by operating the keys in accordance with the lighting order, the input tatami number and the deviation are entered. Data is sequentially stored in the memory.

The stile cutting machine 19 calls each data of the deviations Xa, Xb, Xc, Xd in the length direction stored in the control device 21 by the stile cutting machine terminal device 22 in the order of tatami number, and
Since the pair of cutting bases 19b are set and fixed at predetermined positions and angles, both ends of the tatami floor are cut into a predetermined shape by driving the tatami floor cutting cutter after attaching the tatami floor. .

Next, the trapezoidal tatami mat obtained by the stile cutting step is transferred to a tatami mattress, the tatami mat is overlaid on the tatami mat, and the both mats are sewn and fixed.

Then, this tatami mat is placed on the tatami mat transfer table 20a of the flat stab machine 20. The flat pricking machine 20 calls each data of the deviations Yb, Ye, Yc in the width direction stored in the control device 21 by the flat pricking machine terminal device 23 in the order of the tatami mat number, and the arrow R of the tatami floor is used.
With the movement in the direction, the lower front sewing machine main body 20c is moved in the direction of arrow Q according to the sizes of the deviations Yb, Ye, Yc, and the upper front flat pricking and cutting, the lower front flat pricking and cutting are performed. It is done at the same time.

[0014]

In such a conventional tatami mat shaving device, the key must be operated based on the room dimensions actually measured and recorded at the site to input the tatami number and deviation data. There is a problem that this input is troublesome and an input error occurs, which must be solved.

When the size measuring device of this room is used, as shown in FIG. 7, the size of each side L _{1 to} Ln and the angle between the two sides are centered around the place where the measuring device A is installed. θ ₂
It is possible to obtain polar coordinate data consisting of ˜θn (where n is the number of measurement points).

Such polar coordinate data is collected for each room to be measured, and the data of each room is attached to the room number and stored in the memory.

Since the data stored in the memory is polar coordinate data centered on the place where the measuring apparatus A is installed, the opposite side length Si (where i = 2) is obtained by coordinate conversion.
The above integer) can be obtained by Si = {L ₁ ² + Li ² −2L ₁ · Li · cos θi} ^1/2 , and L ₁ and Si in the triangle formed by L ₁ , Li and Si are The unknown included angle φi of is cosφi = (L ₁ ² + Si ² −Li ² ) / (2L ₁ · Si), and φi = cos ⁻¹ {(L ₁ ² + Si ² −Li ² ) / (2L ₁ Si)}. In this way, the actual shape of the room can be measured.

In the case of coordinate transformation into an orthogonal coordinate system, for example, a straight line connecting both ends (L ₁ , θ ₁ and L ₃ , θ ₃ ) of the upper side of the room is taken as the X axis and perpendicular to this. If a straight line passing through the points (L ₁ , θ ₁ ) is taken as the Y-axis at, each point (L 1
i, θi) can be obtained as a point (xi, yi) by xi = L ₁ cosφ ₃ −Licos (θi + φ ₃ ) yi = L ₁ sinφ ₃ −Lisin (θi + φ ₃ ).

Therefore, in the tatami matting device of the present invention, the keyboard is read by reading the room size data expressed by the local coordinates obtained by such a measuring device or the room size data converted into the orthogonal coordinate system.
