The side side 202 of the tatami mat table 200 is projected from the side surface 208 of the tatami floor 206 (in this embodiment, the side side 206b on the lower front side) by a certain width.

Next, in step S2, as shown in FIG. 6, the vertical drive device 18 is driven to bend the positioning member 12 composed of the first positioning plate 12a and the second positioning plate 12b. It is lowered to a position slightly separated from the tatami mat 200 immediately before it comes into contact with the 200.

The lowering limit is detected by a sensor (not shown), for example, an optical sensor, and is controlled by a control device (not shown).

Specifically, the drive cylinder 34 is operated to drive the drive shaft 36 of the drive cylinder 34 in the extending direction, and the drive frame 30 connected to the drive shaft 36 is horizontally aligned with the arrow E in FIG. Move in the direction.

As a result, the first lever member 28a and the second lever member 28b rotate counterclockwise as shown by the arrow H in FIG. The moving frame 20 moves downward as the first lever member 28a and the second lever member 28b rotate.

With the downward movement of the moving frame 20, the positioning member 12 composed of the first positioning plate 12a and the second positioning plate 12b is configured to descend to the above-mentioned position.

In this state, that is, at a position where the lower end of the positioning member 12 composed of the first positioning plate 12a and the second positioning plate 12b is separated from the tatami mat table 200, as shown in FIG. 7 in step S3. , Activate the pinch moving device 44.

The protruding tip of the tatami mat 200 (in this embodiment, the lower front side side 202b) is sandwiched.
Then, in a state where the tatami floor 206 is placed on the back surface 205 of the tatami mat table 200, the direction away from the side surface 208 of the tatami floor 206 (in this embodiment, the side side 206b on the lower front side) (FIGS. 1 to 2 and 7). Move in the direction of the arrow J).

As a result, in step S4, as shown in FIG. 8, the first positioning plate 12a and the second positioning plate 12b of the positioning member 12 are on the side side of the tatami floor 206 (in this embodiment, the lower front side). By abutting on the side 206b), the first positioning plate 12a and the second positioning plate 12a and the second are opposed to the urging force of the first positioning mechanism 38a and the second positioning mechanism 38b composed of the urging member such as the spring member. The angle α formed with the positioning plate 12 of the above matches the shape of the habit and becomes a predetermined angle α.

Then, in step S5, as shown in FIG. 9, the vertical drive mechanism 40 is operated to lower the pressing member 42 to press the back surface 212 of the tatami floor 206.

In this case, as shown in FIG. 8A, the shape of the habit is recessed in a dogleg shape, or as shown in FIG. 8B, the shape of the habit is projected into a dogleg shape. If the angle formed by the first positioning plate 12a and the second positioning plate 12b of the positioning member 12 is set to be slightly 180 degrees to the upper side in FIG. 8 so as to cope with the habit. good.

Then, after this state is reached, the upper holding member 44a and the lower holding member 44b are separated from each other and opened.

In this state, in step S6, as shown in FIG. 10, the vertical drive device 18 is driven to bend the positioning member 12 composed of the first positioning plate 12a and the second positioning plate 12b. It is lowered to a position where it comes into contact with the tatami mat 200.

As a result, the tatami mat 200 is crushed by the lower ends of the first positioning plate 12a and the second positioning plate 12b, a bending line (bending streak) 203 is attached, and the protruding side side 202 of the tatami mat 200 (this). In the embodiment, the lower front side side 202b) can be bent upward.

In this case, if the protruding side side 202 of the tatami mat 200 cannot be bent slightly upward, the worker may manually bend it upward to some extent, or for example, a push-up member (not shown separately) may be used. , The protruding side side 202 of the tatami mat 200 may be slightly bent upward.

In this state, in step S7, as shown in FIG. 11, the drive mechanisms 50 and 54 of the bending member 46 are driven by the control of a control device (not shown) to match the side shape of the tatami floor 206. The first folding plate 46a and the second folding plate 46b of the bending member 46 are provided so that the angle formed by the first bending plate 46a and the second bending plate 46b of the bending member 46 is a predetermined angle β. , Rotates around the virtual center axis Q.

The predetermined angle β in this case is controlled by a control device (not shown) so as to be an angle α formed by the first positioning plate 12a and the second positioning plate 12.

Next, in step S8, as shown by the arrow in FIG. 12, the bending member 46 composed of the first bending plate 46a and the second bending plate 46b is bent upward to some extent by a drive mechanism (not shown). It is moved in the direction of contacting the protruding side side 202 of the tatami mat table 200 (in this embodiment, the lower front side side side 202b).

As a result, the protruding side side 202 of the tatami mat table 200 (in this embodiment, the lower front side side side 202b) is the first bending plate 46a and the second folding plate 46b of the bending member 46, and the first of the positioning member 12. It is sandwiched between the positioning plate 12a and the second positioning plate 12b so that the side side 202 of the tatami mat 200 can be bent inward (vertically).

The lowering of the pressing member 42 in step S5 and the lowering of the positioning member 12 in step S6 to the contact position can be performed at the same time or in the reverse order.

In the tatami mat folding device 10 of the present invention configured as described above, the above steps S1 to S8 are repeatedly operated.

In this embodiment, as the side side 202 of the tatami mat table 200, the case where the lower front side side side 202b is bent along the shape of the lower front side side side 206b of the tatami mat floor 206 is shown. As a result, it can also be applied to the case where the upper front side side side 202a is bent along the shape of the upper front side side side 206a of the tatami floor 206.

According to the tatami mat folding device 10 of the present invention configured as described above, the angle formed by the first positioning plate 12a and the second positioning plate 12b of the positioning member 12 is predetermined according to the side shape of the tatami floor. The first positioning plate 12a and the second positioning plate 12b of the positioning member 12 are rotated around the virtual center axis P so as to have an angle α of.

Then, in this way, the positioning member 12 positioned at a predetermined angle α according to the shape of the side side of the tatami floor 206 (in this embodiment, the side side 206b on the lower front side) drives the vertical drive device 18. As a result, it descends to a position where it comes into contact with the folded tatami mat table 200.

In this way, with the positioning member 12 (first positioning plate 12a and second positioning plate 12b) lowered to a position where the positioning member 12 (first positioning plate 12a and second positioning plate 12b) comes into contact with the folded tatami mat table 200, the bending member 46 (first bending plate 46a) The second folding plate 46b) is configured to bend the side sides of the tatami mat inward.

Therefore, the tatami mat 200 can be bent in the direction along the tatami floor (direction of the grass), and the side side 202 of the tatami mat 200 (upper front side side 202a and lower front side side 202b). ) Is aligned with the side sides of the tatami floor 206 (the side side 206a on the upper front side and the side side 206b on the lower front side) to form a dogleg shape or a habitual shape protruding into a dogleg shape. It is possible to provide a tatami mat folding device 10 that can be bent into a matching shape, is extremely convenient and has excellent versatility, and has improved work efficiency.

Further, in this way, the side side 202 of the tatami mat table 200 (the side side 202a on the upper front side and the side side 202b on the lower front side) is the side side of the tatami floor 206 (the side side 206a on the upper front side and the side side 206b on the lower front side). It can be bent into a shape that is dented in a dogleg shape or a shape that matches the shape of a habit that protrudes into a dogleg shape, so creases (folding habits) are firmly attached and the corners are rounded. Even when fixing the bent part to the side surface 208 of the tatami floor 206, it can be firmly fixed without becoming a so-called floating state, and a rimless tatami mat with good appearance and high commercial value is manufactured. It is possible to provide a tatami mat folding device 10 capable of performing the same.

Further, the first folding plate 46a and the second folding plate 46b of the bending member 46 are formed according to the shape of the side side 202 of the tatami floor 206 (the side side 202a on the upper front side and the side side 202b on the lower front side). The first bending plate 46a and the second bending plate 46b of the bending member 46 are rotated about the virtual central axis Q so that the angle becomes a predetermined angle β.

As a result, the side side 202 of the tatami mat table 200 (the side side 202a on the upper front side and the side on the lower front side) is formed by the folding member 46 in which the angle formed by the first bending plate 46a and the second bending plate 46b is a predetermined angle β. The side 202b) is aligned with the side side of the tatami floor 206 (the side side 206a on the upper front side and the side side 206b on the lower front side). It can be folded into a shape that matches the shape.

Further, it is configured to be driven by the vertical drive device 18 so as to descend to a position slightly separated from the tatami mat 200 immediately before abutting against the folded tatami mat 200.

Then, at a position separated from the tatami mat 200 in this way, the tatami floor 206 is placed on the back surface 205 of the tatami table 200 by pinching the protruding tip of the tatami table 200 by the operation of the pinching movement device 44. It is designed to move in a direction away from the side of.

As a result, the side sides of the tatami floor 206 (upper front side side 206a and lower front side side 206b) and the positioning member 12 (first positioning plate 12a and second positioning plate 12b) are brought into contact with each other. As a result, the angle formed by the first positioning plate and the second positioning plate becomes a predetermined angle according to the shape of the side sides of the tatami floor 206 (the side side 206a on the upper front side and the side side 206b on the lower front side). As described above, the first positioning plate 12a and the second positioning plate 12b of the positioning member 12 can be rotated about the virtual center axis P.

Therefore, for example, the angle α formed by the first positioning plate 12a and the second positioning plate 12b can be set to a predetermined angle with a simple structure without requiring numerical control, which is convenient.

In this embodiment, the tatami floor 206 is placed on the back surface 205 of the tatami mat 200 by pinching the protruding tip of the tatami mat 200 by the operation of the pinching movement device 44 at a position away from the tatami mat 200. It was configured to move in a direction away from the side of the floor 206.

However, without using such a holding movement device 44, the first positioning mechanism 38a and the second positioning mechanism 38b are not urging members such as spring members as in the embodiment of FIG. 1, and are not shown. However, it is composed of a drive mechanism (horizontal movement device) such as a cylinder mechanism, and the angle α formed by the first positioning plate 12a and the second positioning plate 12b is set to a predetermined angle by controlling a control device (not shown). You can also do it.

In this case, it is sufficient to omit step S2 in which the vertical drive device 18 is driven to descend to a position slightly separated from the tatami mat 200 immediately before abutting against the folded tatami mat 200.

Further, the tatami mat folding device 10 of the present invention has a side side 202 (upper front side side 202a) of the tatami table 200 with respect to the side side of the tatami floor 206 (upper front side side 206a and lower front side side 206b). When the lower front side side 202b) is bent inward, the tatami mat 200 may be configured to be fixed to the side side of the tatami floor 206.

For this fixing, for example, sewing, an adhesive, a tacker, double-sided tape, or the like may be used.

With this configuration, the side sides 202 of the tatami mat table 200 (upper front side side 202a and lower front side side 202b) are combined with the side sides of the tatami floor 206 (upper front side side 206a and lower front side side 206b). ), The tatami mat 200 can be fixed to the side of the tatami floor 206 at the same time as it is bent into a shape that is concave in a dogleg shape or a shape that matches the shape of a habit that protrudes in a dogleg shape. , Integrated production is possible and convenient.

Although not shown, the bending member 46 (first bending plate 46a and second folding plate 46b) is used to heat the bending member 46 (first bending plate 46a and second folding plate 46b). For example, a heater including a sheathed heater or the like may be provided.

This heater heats the vicinity of the bending line 203 when the tatami mat 200 is made of, for example, resin rush, and the folded side side of the tatami mat table 200 (side side 202 of the tatami mat table 200) is bent. It is intended to be softened to facilitate bending from the bending line 203.

The heater is not particularly limited, and a known heater can be adopted. In this case, the heating temperature is not particularly limited and may be appropriately set according to the type of resin rush, and can be set to, for example, 120 ° C.

In this embodiment, the bending member 46 is provided with a heater, but such a heater can be provided on at least one of the bending member 46 and the positioning member 12 described with reference to FIGS. 1 to 3. Of course there is.

Further, although not shown, a folding line forming means is provided as needed to facilitate bending along the folding line 203 for bending the folded side side of the tatami mat table 200 (side side 202 of the tatami mat table 200). A folding line may be formed.

As such a folding line forming means, for example, a squeak member made of a squeeze roller, for example, a heated squeak member made of an electric heating iron can be adopted.

In this case, in the case where the tatami mat 200 is, for example, a tatami mat 200 made of natural rush and a tatami mat 200 made of Japanese paper rush, it is sufficient to form a folding line by a rush member, but it is made of resin. In a tatami mat 200 made of rush, it is desirable to use a rush member and a heated rush member together.

With this configuration, when bending the folded side of the tatami mat 200 (side 202 of the tatami table 200), the vicinity of the folding line 203 is heated to soften it, and the folding line 203 of the tatami table 200 is used as a fulcrum. When folded inward, it becomes easy to bend, it is possible to prevent the side to be bent of the tatami mat 200 from being damaged and damaged, and it is possible to manufacture a rimless tatami mat having a good appearance and high commercial value.

Further, in this embodiment, the first positioning plate 12a and the second positioning plate 12b of the positioning member 12 are composed of plate members arranged perpendicular to the folded tatami mat table 200.

However, as shown in FIG. 13, the first positioning plate 12a and the second positioning plate 12b of the positioning member 12 may be composed of plate members arranged in parallel with the folded tatami mat table 200. ..

When the positioning member 12 is composed of plate members arranged in parallel, as described above, the tatami floor 206 and the tatami table 200 are not placed at the same time, but only the tatami table 200 is placed. It can be an embodiment of bending.

Further, in this embodiment, the bending member 46 (the first bending plate 46a and the second bending plate 46b) is configured to move in the horizontal direction, but as shown in FIG. 14, the bending member 46 (the first bending plate 46a) is configured to move in the horizontal direction. It is also possible to configure the bent plate 46a of 1 and the second bent plate 46b) to move up and down in the vertical direction with respect to the positioning member 12 from below.

Further, as shown in FIG. 15, the first positioning plate 12a and the second positioning plate 12b of the positioning member 12 may be configured to be mutually movable with respect to the virtual center axes P1 and P2, respectively. ..

In this case, as shown in FIG. 15, in the gap S between the first positioning plate 12a and the second positioning plate 12b, the auxiliary positioning member 56 is provided by a drive mechanism (not shown) in FIG. The gap S may be separated and contacted in the direction of the arrow.

Correspondingly, as shown in FIG. 16B, a plurality of bending members 46 composed of the first folding plate 46a and the second folding plate 46b are provided along the side sides of the tatami mat table 200. It may be arranged.

By configuring in this way, as shown in FIG. 20, for example, as in a booth, a plurality of squares are arranged according to the side sides of the tatami floor (the side side on the upper front side and the side side on the lower front side). It can be bent at once into a shape that is recessed in the shape of a dogleg or a shape that matches the shape of a habit that protrudes into multiple doglegs.
(Example 2)

Further, as shown in FIG. 17, the tatami mat folding device 10 of the present invention configured in this way can also be applied to the case where only the tatami mat 200 is bent.

The tatami mat folding device 10 of this embodiment has basically the same configuration as the tatami mat folding device 10 shown in FIGS. 1 to 16, and the same constituent members are designated by the same reference numbers. A detailed description will be omitted.

In this case, as shown in the flowchart of FIG. 18, the step S2, which is driven by the vertical drive device 18 and descends to a position slightly separated from the tatami table 200 immediately before abutting against the folded tatami table 200, is a pinch movement. Step S3 for operating the device 44 may be omitted.

Further, in step S4, the first positioning mechanism 38a and the second positioning mechanism 38b are shown in the second positioning mechanism 38b instead of the urging member such as the spring member as in the embodiment of FIG. However, it is composed of a drive mechanism (horizontal movement device) such as a cylinder mechanism, and the angle α formed by the first positioning plate 12a and the second positioning plate 12b is set to a predetermined angle by controlling a control device (not shown). You just have to do it.

In this case, although not shown, it is also possible to provide a dedicated tatami mat folding device 10 for bending only the tatami mat table 200 without providing the pinching movement device 44.

Although the preferred embodiment of the present invention has been described above, the present invention is not limited thereto, and for example, the tatami mat folding device 10 of the present invention is half tatami mat, although not particularly limited in the above embodiment. It can be configured to correspond to any of 1 and 1 tatami mats.
