By the way, the tatami mat manufacturing apparatus 100 of Patent Document 1 is as disclosed in Patent Document 1.
・ Cutting process to cut the tatami floor to the specified dimensions,
・ Sewing process to sew (sew) the stretched tatami mat on the cut stile side,
The two work processes are performed.

However, in the manufacture of tatami mats,
・ When manufacturing a so-called "new tatami mat" in which a tatami mat is sewn (sewn) on a newly cut tatami floor
-In some cases, the old tatami mat is peeled off, the tatami mat is turned inside out, or the tatami mat is replaced with a new tatami mat and sewn.

In this "table change" work, the size of the tatami mat removed from the room in which it was laid is measured, the thread used to sew the old tatami mat table is cut, and the tatami mat table is peeled off.

For this peeling work, a table or a table made of a frame made of square lumber or the like is usually used.

However, since the store building is small in many small tatami stores, it is difficult to install a separate work table in the surplus space where the tatami manufacturing equipment is placed.

In particular, at the time of changing the table, it is necessary to peel off the existing tatami mat before sewing, and the tatami shop needs a work table on which one tatami mat can be placed. be.

Therefore, for a tatami store with a small store building, there are many uses (needs) required for one tatami manufacturing device, and the tatami manufacturing device can perform the four uses of workbench, cutting, floor bending, and sewing. Is required.
As will be described later, "floor bending" refers to a tatami floor in a state where the end of the tatami mat is chucked, "covered" and tension is applied to the tatami floor that has been bent. A tatami mat can be sewn on the stile, and the tatami mat is not wrinkled and is used to produce a tatami mat with a good finish.

However, the tatami mat manufacturing apparatus 100 of Patent Document 1 is provided with a pair of left and right cutting apparatus 114, 116 sandwiching the central turntable 118.

Therefore, when the pair of left and right cutting devices 114 and 116 are provided in this way, the cutting cutters 104a and 106a and the floor tightening members 114a and 116a are present at the upper part. For this reason, these members become an obstacle, and it becomes difficult to perform the work of peeling the tatami mat surface on the 100 tatami mat manufacturing apparatus of Patent Document 1.

As a result, the fixed pedestal 226 and the turntable 210 of the mobile pedestal 208 can be used as a work table.

However, the fixed pedestal 226 must be provided, the configuration is complicated, and the tatami mat surface cannot be peeled off at an arbitrary height depending on the height of the worker. Also, since the position of the fixed pedestal 226 is fixed, it is impossible to deal with tatami mats of various dimensions.

That is, even for 1 tatami mat, there are tatami mats with different dimensions such as Edo-ma and Honma. Due to their nature, they have become widely used these days, and it is impossible to deal with tatami mats of such various dimensions.

Further, in the tatami manufacturing apparatus 200 of Patent Document 2, one of the stiles must be cut and the turntable 210 must be rotated by 180 ° and sewn with the tatami floor placed on the tatami floor. It is complicated and it is impossible to cut both frames at once to improve work efficiency.

Further, in the tatami manufacturing apparatus 300 having the configuration shown in FIG. 36, the material input side can be used as a work table, but the whole is not flat, and the swivel arm 306 exists to obstruct the tatami mats. Or, some movements such as rotation will be restricted.

After sewing the stile side of one tatami floor A with the sewing unit, when the rotary table is rotated, the tatami floor A is rotated at the position in the lateral direction (width direction) of the tatami manufacturing apparatus main body. If the center of gravity of the tatami mat is not supported when the tatami mat is lifted, the tatami floor A may fall from the rotary table 50 when the rotary table is rotated.

In view of this situation, the present invention also makes a "new tatami mat" in which a new tatami mat floor stile is cut and a tatami mat table is sewn to the tatami mat floor stile. It can also be used for "table change" to change the table, and at the time of "table change", it can be used as a table (working table) that can perform the peeling process to peel off the old tatami mat, and the equipment does not become large. The purpose is to provide tatami-making equipment that is easy to use even in a small installation space such as a small-scale tatami store.
