Description

  The present invention mainly relates to a tatami mat with no rim, that is, a tatami mat cutting / bending device with no rim.

  Conventionally, tatami mats have been mainly manufactured and used in a structure in which edge fabrics are sewn to the upper front side and the lower front side. However, in order to diversify the house and lay tatami directly on the floor between Western styles, to avoid the strong impression that the rim cloth gives even in the Japanese style, or to make the floor area wider on the exterior, the rim cloth is now used. Borderless tatami mats that are manufactured without sewing have been used frequently.

  There is no problem because the heel side is folded to the back side with the warp part of the tatami surface, but the upper front side and the lower front side in the width direction of the tatami mat are folded folds because wefts such as the weeds of the tatami surface are folded, and the edges In the case of an edgeless tatami that does not have a cloth, even if it does not cause a problem in an example in which a normal edge cloth is provided, the commercial value is often lowered. In particular, when the tatami mat is a grass, there is an attempt to make a shallow cutting line on the back side with a sharp blade to make a crease (valley fold line) along the upper front side and the lower front side. In many cases. In view of this, the apparatus disclosed in Patent Document 1 includes an up-and-down moving presser ruler plate with an acute cross section that presses and holds almost the entire length of the upper and lower front of the tatami mat with a predetermined width from above the machine base, and the almost entire length of the tatami mat to be held. The above-mentioned problem is to be solved as a configuration comprising a rotating bent version that supports the frame from the lower surface side and a holding frame.

  If the apparatus disclosed in Patent Document 1 is used, wefts such as weeds can be folded relatively neatly, and there is no edge cloth, but the finished state of the tatami edge is good and the edge has high commercial value. Without tatami mats can be manufactured. However, it is necessary to cut the tatami mat in advance before folding the tatami mat, and there has been a demand for simplification of this process. Prior to cutting the tatami mat, it was necessary to preliminarily mark the cutting position and the folding position on the tatami mat. In addition, the apparatus disclosed in Patent Document 1 may be provided with a cutting cutter that performs cutting while moving along the upper front side or the lower front side. At the time, because of the structure, a space for the holding frame and the rotating bent plate is necessary outside and above the tatami surface bent portion, which may interfere with the moving means of the cutting cutter, etc. (patent) Reference 1, Fig. 3).

The predetermined width referred to here is a width sufficient to fold back inward from the upper or lower front edge of the tatami surface to cover the tatami side surface.

  The long push-up member has a structure that pushes up almost the entire length of the tatami table from below and folds the tatami table, so the long push-up member and the like are less likely to interfere with the moving base, drive means, etc. A tatami mat cutting / bending device for borderless tatami mats, which can cut and bend tatami mats on a table.

  At this time, the long push-up member is an angle plate that pushes up the tatami table with the upper end of the rising portion in contact with the tatami table, and the angle plate pushes up the tatami table so that the bottom surface of the angle plate presses the tatami table. 2. The rimless tatami mat cutting of the rimless tatami mat according to claim 1, wherein a pressing means is provided to push the angle plate above the presser ruler plate after the height of the tip of the press blade is exceeded, and the tatami mat is folded back above the presser ruler plate. It can be a bending device.

  In the folding apparatus disclosed in Patent Document 1, it was difficult to bend the tatami table sharply because of its structure, but this makes it possible to fold the tatami table sharply and more beautifully. A tatami-face tatami mat cutting / bending device for borderless tatami mats, capable of cutting tatami mats and beautiful folding.

  The pushing means is preferably an edgeless tatami mat cutting and bending apparatus in which a rotatable base plate to which an elevating cylinder for raising and lowering the angle plate is fixed is rotated by the rotating cylinder.

  Thereby, the folding of the tatami mat by the pushing means can be performed while securing the function of the angle plate pushing up the tatami mat from below. Further, the pushing means does not interfere with the moving base, the driving means, etc., and it becomes a tatami-less tatami mat cutting and bending apparatus capable of cutting the tatami mat and sharply bending it with a single unit.

  The rimless tatami mat cutting / bending device described in any of the above is used as one unit, and the rimless tatami is provided symmetrically so that the pressing blades of the press ruler plate face the outside one unit at the left and right of the frame. It is also preferable to use a tatami mat cutting and bending apparatus.

  As a result, the upper front side and the lower front side (left and right) of the tatami surface can be cut and bent at the same time, so that the working time is greatly shortened and the production efficiency of the tatami mat is improved.

  5. An edgeless tatami mat folding according to claim 4, comprising adjusting means for adjusting the distance between the left and right units, wherein said adjusting means adjusts the distance between the tips of the pressing blades of the press ruler plate according to the width of the tatami mat. Bending device.

  By providing an adjustment means that adjusts the distance between the left and right units according to the width of the tatami mat, it is not necessary to mark the cutting position or the bending position on the tatami mat surface. Since the lower front side (left and right) can be cut and bent at the same time, the working time is further shortened and the production efficiency of tatami mats is further improved.

  The borderless tatami mat cutting and bending apparatus of the present invention is capable of cutting a tatami mat and beautifully folding it.

It is the perspective view of the tatami surface 8 cut and bent by the tatami mat surface cutting and bending apparatus of an edgeless tatami mat of one embodiment.

  As shown in FIGS. 1 to 2, the rimless tatami mat cutting / bending device of this example includes a table 2, a presser ruler plate 34, a moving base 4, a driving means 42, and an angle plate (long push-up member) 6. The moving base 4 is provided with a cutting device 5. A pushing means 7 for pushing the angle plate 6 to the upper side of the presser ruler plate 34 is provided on the lower side of the table 2.

  The table 2 is installed on the frame 1, and the tatami table 8 is placed on the table 2. The presser ruler plate 34 has a pressing blade 35 at its edge that presses substantially the entire length of the tatami table 8 from above the table 2 and attaches a crease. A press ruler plate 34 is installed so that the position of the tip of the pressing blade 35 coincides with the position of the edge of the table 2 in the vertical direction (see FIG. 8). In addition, the presser ruler plate 34 is installed at the lower part of the vertical movement base 3, and the first cylinder 31 and the second cylinder 32 that connect the vertical movement base 3 and the frame body 1 hold or release the tatami table 8. Vertical movement for is possible. At this time, the tatami table 8 is placed on the table 2 so that the folding direction is upward, that is, the back surface is upward. The folded part is easy to bend if it is humidified, steam sprayed or water applied.

  As shown in FIG. 4, the moving base 4 is connected to a driving roller 43 connected to a driving means 42 (motor) disposed on one end of the up-and-down moving base 3 and a timing belt 45 stretched over the driven roller 44, It is slidably fitted to a rail 41 provided on the upper surface of the vertical movement base 3. The moving base 4 moves forward or backward along the presser ruler plate 34 according to the forward rotation or reverse rotation of the drive roller 43. The transmission of power by the timing belt 45 realizes a detailed forward or backward movement of the moving base 4 and contributes to a good-looking edgeless finish.

  As shown in FIG. 1, the moving base 4 includes a stamping roller 46 that folds the tatami table 8 by reciprocating the entire length of the upper front 81 or the lower front 82 on the upper surface side as the tatami table 8 is cut. A stamping iron 47 is provided. The embossing roller 46 is provided with a ridge that makes it easy to bend the tatami surface when it is rolled to the roller surface while being pressed against the tatami surface. The ridges are provided near the presser ruler plate 34 on one side of the surface of the roller in order to effectively exhibit the action as the creasing blade. On the other hand, the embossing iron 47 has a built-in heater, and when the chemical tatami mat 8 is cut, it can be easily folded by reciprocating the folding position while heating. .

  As shown in FIG. 2, the cutting device 5 includes a rotary cutter 51 provided on the outer side of the pressing blade 35 of the press ruler plate 34 and attached to the moving base 4. In this example, a receiving roller 52 provided with a concave groove extending in the circumferential direction is provided in a pair with the rotary cutter 51. Thus, the tatami surface 8 can be cut without deviation while being sandwiched between the rotary cutter 51 and the receiving roller 52. A drive motor 53 of a rotary cutter 51 is attached to the moving base 4. Then, the tatami mat 8 exposed from the pressing blade 35 of the tatami mat 8 pressed by the presser ruler plate 34 is cut leaving a predetermined width. The predetermined width is a width W sufficient to fold inward from the edge of the upper front 81 or lower front 82 of the tatami surface 8 to cover the tatami side surface, and to match the thickness of the tatami floor, the width of the tatami surface 8, etc. The width is taken inward from the edge of the front 81 or the lower front 82 (see FIGS. 11 and 12). Further, in order to adjust the width W, an adjusting means that enables the cutting device 5 to move left and right with respect to the moving base 4 may be provided.

  The angle plate 6 (long push-up member) is almost equal to or longer than the length (total length) of the upper front 81 side or lower front 82 side of the tatami table 8 and is pressed to the side of the table 2 Parallel to the ruler plate 34, the upper end of the rising portion 61 is in contact with the tatami mat 8 and is pushed up. Further, it is installed in the horizontal direction with an interval of about the thickness of the tatami mat 8 from the tip of the pressing blade 35. On the bottom surface 62 of the bottom portion of the angle plate 6, a push-up bar 63 connected to the elevating cylinder 64 is connected to the left and right (see FIG. 4). The elevating cylinder 64 is fixed to the base plate 71, and the elevating rod 63 and the angle plate 6 ascend along the direction (vertical direction) of the rail 65 provided on the lower side surface of the elevating rod 63 by the action of the elevating cylinder 64. By doing so, the rising portion 61 pushes up almost the entire length of the tatami table 8 from below the tatami table 8, and a crease is made along the upper front 81 or the lower front 82 of the tatami table 8.

  As shown in FIG. 2, the push-in means 7 is formed by rotating a base plate 71 that is rotatable about a rotation shaft 72 to which the elevating cylinder 64 is fixed, with a rotation cylinder 73. The rising portion 61 of the angle plate 6 pushes up the tatami surface 8, and the lower surface 62 of the bottom of the angle plate 6 exceeds the height of the tip of the pressing blade 35 of the presser ruler plate 34 that presses the tatami surface 8, and then rotates. The cylinder 73 is retracted and the angle plate 6 is pushed into the upper side of the presser ruler plate 34. As a result, the tatami table 8 is folded back to the upper side of the presser ruler plate 34.

  Hereinafter, a procedure for cutting and bending the tatami surface 8 using the rimless tatami surface cutting and bending apparatus of the first embodiment of the present invention will be described. First, the folding position is marked on the back surface of the tatami surface 8 according to the desired width of the tatami mat. Thereafter, with the first cylinder 31 and the second cylinder 32 extended, as shown in FIG. 2, the tatami table 8 is placed on the table 2 with the direction of turning up, that is, the back side facing up. Then, the first cylinder 31 is retracted, and the presser ruler plate 34 installed on the vertical movement base 3 is brought close to the tatami mat 8. In this state, the presser ruler plate 34 does not press the tatami surface 8. In this state, the folding position of the tatami surface 8 is adjusted to the tip position of the pressing blade 35 of the presser ruler plate 34. At this time, the distance between the tatami surface 8 and the presser ruler plate 34 is preferably 20 mm or less. This is because if the interval is larger than 20 mm, it is difficult to accurately position the bending position marked on the tatami surface 8 at the tip position of the pressing blade 35 of the pressing ruler plate 34. The distance between the tatami surface 8 and the presser ruler plate 34 is more preferably 10 mm or less.

  Thereafter, as shown in FIG. 3, the second cylinder 32 is retracted, and almost the entire length of the tatami mat 8 is pressed by the presser ruler plate 34. In this state, the tatami table 8 exposed from the pressing blade 35 substantially coincides with the height of the gap between the rotary cutter 51 and the receiving roller 52. Then, as shown in FIG. 5, the tatami table 8 exposed from the pressing blade 35 is cut while being sandwiched between the rotary cutter 51 and the receiving roller 52. At this time, when the tatami table 8 is made of cocoon grass, the embossing roller 46 is used, and when the chemical fiber or the like is used (chemical tatami mat tatami table 8), the embossing iron 47 is fitted with the pressing blade 35 of the presser ruler plate 34. A crease is made in the tatami surface 8 at the tip.

  In the first embodiment, the first cylinder 31 and the second cylinder 32 are used in combination. However, the present invention is not limited to this, and only one of the cylinders may be used. However, the workability is greatly improved by combining the first cylinder 31 and the second cylinder 32. When placing the tatami table 8 on the table 2, both the cylinders are extended so that the distance between the table 2 and the presser ruler plate 34 is increased so that the upper front 81 side or the lower front 82 side of the tatami table 8 is It becomes easy to insert between the table 2 and the presser ruler plate 34. When positioning the tatami table 8, as described above, only the first cylinder 31 is retracted to facilitate positioning. In the first embodiment, the stroke of the first cylinder 31 is 70 mm and the stroke of the second cylinder 32 is 3 mm, so that the presser ruler plate 34 presses the tatami surface 8 when both cylinders are retracted. It is set.

  After cutting the tatami table 8, as shown in FIGS. 6 and 9, the elevating cylinder 64 is extended to cause the rising portion 61 of the angle plate 6 to push up almost the entire length of the tatami table 8 from below. As a result, the tatami table 8 is bent at a substantially right angle (see FIG. 12). In the first embodiment, the rising portion 61 of the angle plate 6 is configured to bend the tatami surface 8. However, the present invention is not limited to this. A long plate-like member may be used instead of the angle plate 6 as long as the entire length of the tatami table 8 is pushed up from below and the tatami table 8 is simply bent at a right angle. However, as will be described later, if the tatami surface 8 is bent at an acute angle, the angle plate 6 is used and the rising portion 61 needs to be configured to bend the tatami surface 8.

  Even in this state, the tatami surface 8 is sufficiently bent, but the bottom surface of the bottom of the angle plate 6 as shown in FIG. 7 and FIG. After 62 exceeds the height of the tip of the pressing blade 35 of the presser ruler plate 34 pressing the tatami surface 8, the rotating cylinder 73 is retracted and the angle plate 6 is pushed into the upper side of the presser ruler plate 34. As a result, the tatami table 8 is folded back to the upper side of the presser ruler plate 34.

  8 to 10 are enlarged views of how the tatami surface 8 is bent. In the first embodiment, the R portion (see FIG. 8) is provided on the side of the presser ruler plate 34 at the upper end of the rising portion 61, but this is not restrictive. However, it is preferable to provide the R portion on the side of the presser ruler plate 34 of the rising portion 61 so that the rising portion 61 of the angle plate 6 can bend the tatami surface 8 more easily.

  FIG. 11 shows the tatami table 8 that is bent by pressing the angle plate 6 onto the upper side of the presser ruler plate 34 after cutting. The tatami surface 8 is bent sharply and beautifully. By using the edge-less tatami mat cutting and bending apparatus of the first embodiment, it is possible to cut the tatami mat 8 and cleanly fold it with a single unit. This makes it possible to easily provide a tatami mat product having a good tatami rim finish and a high commercial value, although it is a tatami mat without an edge fabric.

  However, in the above process, only one of the upper front 81 side or the lower front 82 side of the tatami table 8 is cut and bent, and the other is not cut or bent (see FIGS. 11 and 12). Therefore, in the tatami mat cutting / bending device of the rimless tatami according to the first embodiment, after either the upper front 81 side or the lower front 82 side is cut and bent, the tatami surface is rotated 180 degrees, The lower front 82 side or the upper front 81 side also needs to be cut and bent. It is also necessary to measure the folding dimensions in advance and mark the folding position etc. on the tatami surface 8. Therefore, a second embodiment of the present invention that solves these problems all at once will be described below.

  FIGS. 13 to 14 show a rimless tatami mat cutting and bending apparatus according to a second embodiment of the present invention, and FIG. 13 is a front view of the rimless tatami mat folding and bending apparatus according to the second embodiment. FIG. 14 is a front view of the edgeless tatami mat cutting and bending apparatus in which the distance between the tips of the pressing blade 35 and the pressing blade 351 in FIG. 13 is widened from W1 to W2. FIG. 15 is a perspective view of the tatami table 8 that has been cut and bent by the rimless tatami table cutting and bending apparatus of the second embodiment in the state of FIG. 13.

  In the second embodiment of the present invention, the frame 1 is attached to the edgeless tatami mat cutting and bending apparatus (first unit A) provided at one end of the frame 1 shown in FIGS. The second unit B is added to the other end (left side in FIG. 13). Each unit is provided approximately symmetrically so that the pressing blade 35 of the presser ruler plate 34 and the pressing blade 351 of the presser ruler plate 341 face each outside, one unit on each side of the frame 1. . Further, there is provided adjusting means 9 for adjusting the interval between the left and right units of the frame body 1 according to the width of the tatami mat with reference to the interval between the tip of the pressing blade 35 and the tip of the pressing blade 351. Thereby, the upper front 81 side and the lower front 82 side (left and right) of the tatami surface 8 can be simultaneously cut and bent with desired dimensions.

  As shown in FIG. 13, the table 201 of the second unit B is provided with moving rollers 21 on the left and right, so that the table 201 can move the upper part of the frame 1 left and right. A positioning ball screw 93 (female screw) is fixed to the lower surface 62 of the table 201 and is fitted to a motion transmission screw 92 (male screw) that is rotated by a positioning motor 91 fixed to the inner surface of the upper portion of the frame 1. An adjusting means 9 for adjusting the interval between the left and right units of the frame 1 is configured.

  As a specific method for adjusting the interval between the left and right units of the frame 1, for example, a position sensor that detects the tip position of the pressing blade 351 of the presser ruler plate 341 of the second unit B is used as the first unit A. The presser blade 351 of the presser ruler plate 341 of the second unit B is provided with a plurality of locations according to the width of the desired tatami mat (Kyoma, Edo, etc.) with the tip of the presser blade 35 of the presser ruler plate 34 as a reference. It can be realized by providing a control means for rotating or reversing the positioning motor 91 until it reaches a position where the tip of the tatami reaches the desired tatami width. FIG. 14 shows a state in which the second unit B is moved away from the first unit A from the state of FIG. 13 so as to correspond to a larger tatami width W2.

  FIG. 15 shows a perspective view of the tatami table 8 that has been cut and bent by the rimless tatami table cutting and bending apparatus of the second embodiment in the state of FIG. According to the tatami width W1, the upper front 81 side and the lower front 82 side of the tatami surface 8 are both divided and bent. From this state, the upper front 81 side and the lower front 82 side are opened, and they are sewn on the tatami floor.

  In the tatami surface cutting and bending apparatus of the rimless tatami of the second embodiment, since the upper front 81 side and the lower front 82 side (left and right) of the tatami surface can be simultaneously cut and bent, the working time is greatly reduced. The production efficiency is improved. In addition, by providing an adjustment means 9 that adjusts the distance between the left and right units A and B according to the width of the tatami mat, there is no need to mark the folding dimensions etc. on the tatami surface 8, and quickly according to the type of tatami mat. Since the left and right sides of the tatami surface 8 can be cut and bent at the same time, the working time is further shortened and the production efficiency of the tatami mats is further improved. This makes it possible to more easily provide a product with a good tatami edge finish and a high commercial value, although it is a tatami mat without an edge fabric.
