  The stopper 92 and the fixing member 98 configured as described above are arranged in the lateral direction (left and right direction in FIG. 1) of the tatami mat folding apparatus 10 along the side 202 of the tatami mat 200 as shown in FIG. It extends.

The tatami surface folding apparatus 10 of the present invention configured as described above will be described below with reference to FIGS.
1 and 2, reference numeral 130 denotes a control panel for controlling the tatami mat folding apparatus 10 of the present invention.
(1) Arrangement process of tatami mat

  First, as shown in FIGS. 6 and 10, the tatami table 200 is arranged on the upper surface of the mounting table 24 so that the back surface of the tatami table 200 is positioned upward. That is, the bent side of the tatami table 200 (one side 202 of the tatami table 200) is positioned on the upper surface of the mounting table 24 and is positioned on the bending side end portion 26 of the mounting table 24.

  At this time, by driving the lifting drive cylinder 34 of the bending mechanism 28, as shown in FIG. 6, the upper surface of the mounting table 24 and the upper end surface 44 of the bending member 30 have a horizontal height. Make sure the positions match.

  At this time, the folding line 206 of the tatami mat table 200 set in advance according to the height of the side surface of the tatami floor is positioned at the folding side end portion 26 of the placing table 24 and the folding side of the placing table 24 is also folded. The tatami surface 200 is placed so as to protrude from the end portion 26 in the direction of the bending member 30 by a predetermined bending width.

  In this adjustment, the other bent side of the tatami table 200 that has not been bent yet (the other side 202 of the tatami table 200) is brought into contact with a stopper 92 disposed on the rear end side mounting table 90. Thus, the side to be folded of the tatami table 200 (one side 202 of the tatami table 200) may be positioned with respect to the end 26 of the placing table 24. In other words, the folding line 206 of the tatami table 200 may be set so as to be positioned at the folding side end portion 26 of the placing table 24.

  Further, in this case, the driving mechanism 22 is driven along the guide rail 16 in advance so that the folding line 206 of the tatami table 200 is positioned at the bending side end portion 26 of the mounting table 24. Then, the tatami surface folding unit 14 is moved in the front-rear direction (left-right direction in FIGS. 4 to 6 (in the direction of arrow E)) to adjust the position.

Thereby, according to the tatami floor which has various width | variety, the to-be-folded side edge (side 202 of the tatami surface 200) of the tatami surface 200 can be bent now.
Note that the first folding side is the upper front side of the tatami mat, and the tatami mat has no habit, so that the folding support member 56 is arranged so that the desired folding position of the tatami surface 200 (the crease position of the grass) becomes the folding line 206. It is also possible to set the position without using the stopper 92 in particular, with the tip 56d and the like as a guide.

  In addition, instead of moving the tatami mat folding unit 14 in the front-rear direction (left-right direction in FIGS. 4 to 6 (in the direction of arrow E)) by driving the drive mechanism 22 in this way, for example, mounting is performed. A scale may be engraved on the side surface of the mounting table 24, and the folding line 206 of the tatami table 200 may be manually positioned at the folding side end portion 26 of the mounting table 24 in accordance with this.

  In this case, although not shown, a bending accelerator is applied, immersed, or sprayed on the bent side of the tatami table 200 (the side 202 of the tatami table 200, particularly in the vicinity of the fold line 206 of the tatami table 200). (Blowing) is preferable because bending becomes easy.

As such a folding accelerator, for example, water, high-temperature steam, a highly permeable surfactant, or the like can be used. As a result, when the folded side of the tatami table 200 (side 202 of the tatami table 200) is folded inward with the folding line 206 of the tatami table 200 as a fulcrum, the folded side of the tatami table 200 is damaged and damaged. It is possible to produce an edgeless tatami mat that has a good appearance and high commercial value.
(2) Bending preparation process

  Next, in this state, as shown in FIGS. 6 and 11, the drive cylinder 58 of the bending support mechanism 54 is operated, the drive shaft 60 of the drive cylinder 58 is extended, and the bending support member 56 is lowered. . And the front-end | tip 56d of the inclination support part 56b of the bending support member 56 is located in the bending line 206 of the tatami surface 200. FIG. As a result, the tatami mat 200 is sandwiched between the lower surface of the bending support member 56 and the upper surface of the mounting table 24, and is fixed so that the positional displacement of the tatami mat 200 does not occur.

  In this case, as shown in FIGS. 6 and 11, the lower surface of the bending support member 56 and the mounting table are operated by operating the link mechanism 66 in advance to contract the drive shaft 68 a of the drive cylinder 68. The upper surface of 24 is kept parallel.

  At this time, the driving cylinder 100 of the tatami surface end fixing mechanism 96 is operated to extend the driving shaft 1 driving shaft 102 and to lower the fixing member 98, so that the lower surface of the fixing member 98 and the rear end side mounting are placed. The tatami mat 200 is sandwiched between the upper surface of the table 90 and fixed so that the positional deviation of the tatami mat 200 does not occur.

  In this case, although not shown, the folding side of the tatami table 200 (side 202 of the tatami table 200) is predetermined on the mounting table 24 from the bending side end portion 26 of the mounting table 24 in the direction of the bending member 30. In a state where the tatami table 200 is placed on the placement table 24 so that the tatami table 200 is placed so as to protrude by the folding width of the tatami table 200, the side to be bent of the tatami table 200 (side 202 of the tatami table 200) is A cutting means for cutting may be provided.

  Thereby, the folding side of the tatami table 200 (side 202 of the tatami mat 200) is bent along the side of the tatami floor by a predetermined folding width, and the bent side is turned to the side of the tatami floor, or Sewing to the back surface or fixing with an adhesive can be performed reliably.

  Note that the folding support member 56 and the fixing member 98 may be fixed to the tatami surface 200 at the same time, or one of them may be performed first.

  In this manner, with the folding support member 56 and the fixing member 98 fixed to the tatami table 200, as shown in FIG. A fold line that facilitates bending may be formed along a fold line 206 that folds the fold side (side 202 of the tatami table 200).

  In the embodiment shown in FIG. 11, as the folding line forming means 104, as shown in FIG. 1, for example, a yoke member 108a made of a yoke roller, for example, a heating yoke member 108b made of an electric heating iron is provided. Yes.

  As shown in FIG. 1, the yoke member 108a and the heating yoke member 108b are bent by the side of the tatami table 200 (the side 202 of the tatami table 200) by the moving mechanism 110 including the drive motor 110a and the chain 110b. ) And a folding line that facilitates folding can be formed along the folding line 206.

  In this case, when the tatami table 200 is, for example, a tatami table 200 made of natural rush grass or a tatami table 200 made of Japanese paper rush grass, it is sufficient to form a fold line by the yoke member 108a. In the tatami table 200 made of grass, etc., it is desirable to use the yoke member 108a and the heated yoke member 108b in combination.

  With this configuration, when the folding side of the tatami table 200 (side 202 of the tatami table 200) is folded inward with the fold line 206 of the tatami table 200 as a fulcrum, the folding line forming means forms the folding line. It is easy to bend along the gusset line, and the bent side of the tatami table 200 (side 202 of the tatami table 200) can be prevented from being damaged and damaged, and an edgeless tatami mat that has good appearance and high commercial value can be manufactured. it can.

Further, in this case, as shown in FIGS . 8 and 11, the base end portion 40 of the bending member 30 is provided with a heater 50 made of, for example, a sheathed heater for heating the bending member 30. Is desirable.

With this configuration, when the side to be folded of the tatami table 200 (the side 202 of the tatami table 200) is folded, the vicinity of the fold line is heated and softened, and the fold line 206 of the tatami table 200 is used as a fulcrum. When folding, it becomes easy to bend, the side to be folded of the tatami surface 200 can be prevented from being damaged and damaged, and an edgeless tatami mat having a good appearance and high commercial value can be manufactured.
(3) Startup process

  Next, after heating and folding lines are formed as necessary as described above, the ascending / descending drive cylinder 34 of the folding mechanism 28 is driven as shown by the arrows in FIG. Accordingly, the tatami surface rising surface 46 constituting the rising portion of the bending member 30 is raised.

  Accordingly, as shown in the enlarged views of FIGS. 12 and 16, the folding side 206 (side 202 of the tatami mat 200) of the tatami mat 200 is bent by the tatami mat rising surface 46 with the folding line 206 of the tatami mat 200 as a fulcrum. Stand up vertically.

  Thus, only the tatami table 200 can be bent in advance in a direction perpendicular to the weave texture direction (the direction of the weeds) without damaging the surface of the tatami table 200.

In this case, as shown in the enlarged view of FIG. 16, the width H between the folding side end portion 26 of the mounting table 24 and the tatami surface rising surface 46 constituting the rising portion of the bending member 30 is as follows. The thickness of the tatami mat 200 is preferably set to be slightly smaller . This makes it easy for the bent side of the tatami table 200 (side 202 of the tatami table 200) to rise in the vertical direction.

  The adjustment of the width H in this case is performed by moving the bending mechanism 28 in the direction of contacting / separating the bending side end portion 26 of the mounting table 24 by driving the drive cylinder 32.

Further, in this case, the ascending degree of the bending member 30 driven by the raising / lowering drive cylinder 34 of the bending mechanism 28 exceeds the tatami surface rising surface 46 of the bending member 30 and is in the middle of the tapered inclined surface 48 constituting the press surface. The bending side end portion 26 of the mounting table 24 is located at the height position.

  Thus, after the vertical start of the bent side of the tatami table 200 (the side 202 of the tatami table 200) by the tatami surface rising surface 46 of the bending member 30 is completed, the enlarged views of FIGS. As shown, the drive cylinder 32 of the bending mechanism 28 is driven.

That is, as shown by the arrows in FIGS. 13 and 17, the bending member 30 is moved in a direction approaching the bending side end portion 26 of the mounting table 24. In this case, the mounting table 24 side of the intermediate portion 38 of the folding member 30, so enter recesses 42 are formed, bent end 26 of the loading table 24 and enter the entrance recess 42, It is comprised so that this movement may not be inhibited.

  As a result, the bent side of the tatami table 200 (side 202 of the tatami table 200) and the tapered inclined surface 48 constituting the press surface of the bending member 30 are brought into contact with each other, and the bent side of the tatami table 200 is brought into contact with the tatami table 200. Is bent inward with the fold line 206 as a fulcrum.

  In this case, as shown in the enlarged view of FIG. 17, the angle α formed between the tapered inclined surface 48 of the bending member 30 and the horizontal plane, and the angle β formed between the inclined guide surface 56c of the bending support member 56 and the horizontal plane are expressed by α> β It is set to be a relationship.

If the angle α formed between the tapered inclined surface 48 of the bending member 30 and the horizontal plane and the angle β formed between the inclined guide surface 56c of the bending support member 56 and the horizontal plane are set in such a relationship, the bent side of the tatami table 200 is set. When the (side 202 of the tatami mat table 200) is folded inward with the fold line 206 of the tatami mat table 200 as a fulcrum, the tatami mat table is inclined between the inclined guide surface 56c of the fold support member 56 by the tapered slant surface 48 of the fold member 30. The bent side of 200 (side 202 of the tatami table 200) is not firmly sandwiched.
Further, if the angle is set to satisfy the relationship of α> β as described above, the taper inclined surface 48 ensures that the folding pressure of the tatami surface 200 is applied to the tip 56d of the folding support member 56. Therefore, it is possible to bend the tatami surface with good dimensional accuracy.

Therefore, when the folding line 206 of the tatami surface 200 is folded inwardly, the side to be folded of the tatami surface 200 (the side 202 of the tatami surface 200) can be prevented from being damaged and damaged, and has a good appearance and high commercial value. Without tatami mats can be manufactured.
(5) Separation process of the bending support member 56

  Next, from this state, as shown in the enlarged views of FIGS. 14 and 18, the folding support member 56 is moved away from the bent side of the tatami mat 200 (the side 202 of the tatami mat 200) (see FIG. 14). 14, see arrow in FIG.

  That is, as shown in FIGS. 14 and 18, the drive cylinder 68 of the link mechanism 66 of the bending support mechanism 54 is operated to extend the drive shaft 68 a of the drive cylinder 68.

  Accordingly, as shown by the arrows in FIGS. 14 and 18, the drive cylinder 58 rotates, and the bending support member 56 is moved to the side to be bent (tatami table) of the tatami table 200 as the drive cylinder 58 rotates. It is turned in a direction away from the side edge 202 of 200.

At the same time, by operating the drive cylinder 58 of the folding support mechanism 54, reducing the drive shaft 60 of the driving cylinder 58. As a result, as shown by the arrows in FIGS. 14 and 18, the folding support member 56 connected to the tip of the drive shaft 60 is separated from the bent side of the tatami table 200 (side 202 of the tatami table 200). Move to.

In this case, the amount of movement of the bending support member 56 is determined by pressing between the bent side of the tatami mat 200 (side 202 of the tatami mat 200) and the tapered inclined surface 48 constituting the press surface of the bending member 30 in the next pressing step. It is configured to the extent that it does not get in the way.
(6) Pressing process

  Next, in this state, as shown in the enlarged views of FIGS. 15 and 19, the elevating drive cylinder 34 of the bending mechanism 28 is driven to lower the bending member 30.

  That is, by moving the bending member 30 so as to be in a lower position with respect to the placement table 24, as shown by the arrows in FIGS. The side 202) is further bent inward with the fold line 206 of the tatami surface 200 as a fulcrum.
