Further, the tatami-mat facing that is originally hard to be bent can be easily bent, thereby responding to a requirement of thinning of tatami-mat facing.SELECTED DRAWING: Figure 1

Description

  The present invention relates to a processing apparatus and a processing method for a tatami mat, and more specifically to a processing apparatus and a processing method for a tatami mat (so-called goza) used for manufacturing a tatami mat.

5A and 5B are a plan view and a sectional view of a general tatami mat known from the past.
As shown in FIG. 5, the tatami 2 is composed of a tatami floor 12 that is a core material and a tatami surface 3 that covers the tatami floor 12. The tatami mat 3 (goza) is composed of, for example, rushes or rushed linear members knitted with yarn. This point is the same in the present invention.

A conventional tatami mat manufacturing process is shown in FIG.
In the step (a) shown in FIG. 6, a tatami mat material made of rush or the like is prepared, and an unnecessary portion 9 is cut out to finish the tatami mat 3 of a design size.
Next, in the step (b), the tatami mat 3 having the design size is relatively overlapped with the tatami floor 12. As shown in FIG. 6B, the tatami table 3 has a size that protrudes from both ends of the tatami floor 12.
Next, in the step (c), both end portions of the tatami mat 3 that are overlapped relative to the tatami floor 12 are bent into a substantially U-shape, and both end portions of the tatami mat floor 12 are wrapped with both end portions of the tatami mat 3. The end of the tatami table 3 is bent manually.
Through the above steps, as shown in FIG. 6 (d), a state where both ends of the tatami floor 12 are covered by both ends of the tatami table 3 bent into a substantially U-shape is ensured.

  However, the work of bending both ends of the tatami table shown in FIG. 6 (c) is a work of processing a large number of linear members such as rushes in the bending direction at the same time. Met. That is, the folding operation of the tatami surface is a manual operation that requires a lot of time and labor, so that there is a problem that the working efficiency is remarkably poor.

  Further, when a large number of linear members such as rushes are bent, resistance due to the linear members (such as rushes) acts strongly. For this reason, it is not easy to bend the end portion of the tatami surface 3, and much effort is required to fold the end portion of the tatami surface 3 straight and cleanly. In addition, when folding the tatami surface, there is a risk that the appearance of the tatami may be impaired by cracks at the folding location.

  In recent years, there has been an increasing demand for “thinning the tatami mat”. However, due to the difficulty of bending the end of the tatami surface 3 (resistance at the time of folding, etc.), the demand could not be met.

  Therefore, in view of the above-described problems of the prior art, the object of the present invention is to be able to perform folding of a tatami surface simply and as designed with labor-saving, and further to meet the demand for “thinning the tatami mat”. It is an object of the present invention to provide a tatami table processing apparatus and processing method.

  The above-described object is achieved by a processing apparatus for use in manufacturing a tatami mat, which is provided with a grooving means for forming a groove along a planned folding position of the tatami surface.

  In the processing apparatus, the grooving means includes, for example, two rotary and coaxial grooving blades.

  Moreover, in the said processing apparatus, it is preferable that the two grooving blades are provided so that a space | interval can be adjusted freely.

  Moreover, it is preferable that the said processing apparatus is further equipped with the length cut blade for cutting unnecessary length from a tatami surface.

  Moreover, in the said processing apparatus, it is preferable that the length cut blade is provided so that the space | interval with a grooving means can be adjusted freely.

  Moreover, it is preferable that the said processing apparatus is further equipped with the groove depth holding means for keeping constant the depth of the groove | channel formed in a tatami surface.

The above-mentioned purpose is
Form a groove along the planned folding position of the tatami surface,
Overlay the tatami mat on the tatami floor with the groove forming surface facing inward (towards the tatami floor)
The side of the tatami mat is folded into a substantially U shape so as to cover the side of the tatami floor, and the tatami mat is folded along a groove formed inside the planned folding position of the tatami mat. Achieved by the method.

  In the said processing method, it is preferable to form the said groove | channel along a ruler.

  Moreover, in the said processing method, it is preferable that the said groove | channel formed in a tatami surface is a curved concave shape.

  Moreover, in the said processing method, it is preferable that the depth of the said groove | channel formed in a tatami surface is 1 mm or less.

  The processing apparatus of the present invention includes grooving means for forming a groove along a planned bending position of the tatami mat (goza). By using such a processing apparatus, it is possible to easily add a groove to the expected folding position of the tatami surface, and as a result, it is possible to easily fold the tatami surface which is difficult to bend along the groove with labor saving. Further, by providing a groove in advance, the bent portion of the tatami surface becomes a smooth bend (without cracks or the like), and the end portion of the tatami surface can be finished cleanly. Furthermore, since a tatami surface that is difficult to bend can be bent smoothly and easily, it is possible to meet the conventional demand for thin tatami mats.

  The grooving means included in the processing apparatus of the present invention is configured to include two rotary and coaxial grooving blades. By providing such two rotary grooving blades in an aligned state, grooves can be simultaneously formed at two planned folding positions (substantially U-shaped folding positions) of the tatami surface.

  In the processing apparatus of the present invention, the two grooving blades are provided so that the interval can be freely adjusted. Thereby, since the space | interval of the parallel groove | channel can be adjusted freely, it can respond to the tatami floor of various thickness. That is, it becomes possible to deal with the production and mass production of tatami mats with various thicknesses.

  The processing apparatus of the present invention includes a length cutting blade for cutting an unnecessary length from a tatami mat. This makes it possible to cut an unnecessary length at the same time as grooving the tatami mat and further improve the efficiency of tatami mat processing.

  In the processing apparatus of the present invention, the length cutting blade is provided so that the interval with the grooving means can be freely adjusted. Thereby, it can respond to the process of the tatami mat of various sizes.

  The processing apparatus of the present invention includes groove depth holding means for keeping the depth of grooves formed on the tatami surface constant. As a result, it is possible to reliably prevent the tatami surface from being folded at the planned folding position and to maintain the optimum groove depth for folding.

  In the processing method of the present invention, grooves (grooves for facilitating the folding of the tatami mat) are formed along the planned folding positions of the tatami mat, and the tatami mat is relatively overlapped with the tatami floor with the groove forming surface facing inward. In addition, the side of the tatami mat is folded into a substantially U shape so as to cover the side of the tatami floor, and the tatami mat is folded along a groove formed inside the planned folding position (folding planned position) of the tatami mat. At the time of folding the tatami surface, the groove forming portion is located inside the bent portion (corner portion). By processing the tatami mat in such a way, it is possible to easily fold the tatami mat which is difficult to bend along the groove with labor saving. In addition, by providing a groove in advance, the bent portion of the tatami surface becomes a smooth bend, and the tatami surface can be finished finely. Furthermore, since it is possible to easily fold a tatami table that is inherently difficult to bend, it is possible to meet the conventional demand for “thinning tatami mats”.

  In the processing method of the present invention, grooves are formed along a ruler. As a result, the tatami table can be folded along a straight line at the planned folding position, so that the folds of the tatami table do not meander or bend. That is, it is possible to finish the tatami mat with the tatami table cleanly.

  In the processing method of the present invention, it is desirable that the groove formed on the tatami surface is a curved concave shape. For example, when the shape of the groove is substantially V-shaped, there is a risk of cracks from the V-shaped groove toward the opposite side of the tatami surface when the tatami surface is bent. Thus, occurrence of such cracks (occurrence of cracks starting from the grooves) can be prevented. That is, the corner portion after the bending process becomes smooth on both sides, and the processed tatami surface can be finished cleanly.

  In the processing method of the present invention, the groove formed on the tatami surface preferably has a groove depth of 1 mm or less. This makes it possible to fold the tatami table without damaging the expected folding position of the tatami table.

(Tatami surface processing method)
First, a tatami mat processing method according to the present invention will be described with reference to FIGS.
FIG. 1 is a process diagram showing a tatami mat processing method according to the present invention.
FIG. 2 is an enlarged view showing a grooving process for the tatami mat.
FIG. 3 is a plan view showing the appearance of the tatami mat before and after the grooving step.
In addition, process ac demonstrated below respond | corresponds to Fig.1 (a)-(c).

Step a:
A tatami surface material (so-called goza) used for manufacturing tatami mats is prepared, and grooves 5 and 6 are formed along the planned folding positions of the tatami surface 3 as shown in FIGS. At the same time as grooving, an unnecessary length 9 is cut from the tatami mat surface material. By cutting the unnecessary length, the tatami table 3 having the design size can be obtained.

The grooves 5 and 6 form grooves along the planned folding position of the tatami mat 3 (specifically, the inner corner portion of the planned folding position). The planned folding position means a corner portion of the tatami table 3 that can be formed when the tatami table 3 is folded. Means the position of two folds (scheduled crease position) formed in a straight line and in parallel at the inner corner portion of the.
Further, as shown in FIG. 3, the grooves 5 and 6 are formed in a direction crossing a linear member such as an rush that constitutes a tatami (specifically, in a substantially perpendicular direction).

  In forming the grooves 5 and 6, a processing apparatus 1 as shown in FIG. The details of this processing apparatus (grooving and cutting apparatus) will be described later.

  When the grooves 5 and 6 are formed, it is preferable to form them straight using a ruler as shown in FIG. The ruler is used to advance a grooving blade and a length cutting blade of the processing apparatus 1 described later straight. That is, a ruler is used to form the grooves 5 and 6 straight and parallel to the tatami mat 3 and to cut the unnecessary length 9 straight.

  The shape of the grooves 5 and 6 formed in the tatami mat 3 (the shape in the cross-sectional direction) is not particularly limited, but as shown in the enlarged view of FIG. 2B, it is a curved concave shape (for example, a semicircular shape or a semielliptical shape). Preferably there is. By forming the grooves 5 and 6 into curved concave shapes, it is possible to prevent occurrence of cracks (generation of cracks starting from the grooves 5 and 6) when the tatami surface 3 is bent. That is, the corner portion after the bending process becomes smooth, and the processed tatami mat can be finished finely.

  The size of the grooves 5 and 6 formed in the tatami surface 3 is not particularly limited, but the depth of the grooves is preferably 1 mm or less. This makes it possible to fold the tatami table without damaging the expected folding position of the tatami table.

  The material of the tatami mat to be used (tatami mat surface material) is not particularly limited, and in addition to the natural rush material, an rush-like material (a material that looks like an rush, or a material that imitates an rush) can be used. Specific examples of the rush-like material include, for example, a material obtained by processing Japanese paper or the like into an rush-like shape (in the form of an elongated stem or a line). In addition to Japanese paper, it is also possible to use resin.

Step b:
After attaching the grooves 5 and 6 to the tatami mat 3 and cutting the unnecessary length 9 through the procedure described above, the tatami mat 3 is placed on the tatami floor 12 (core material) with the groove forming surface facing inward as shown in FIG. ) Relative to each other. Although the material of the tatami floor 12 is not particularly limited, for example, a generally used insulation board can be used as the tatami floor.

Step c:
Next, as shown in FIG.1 (c), the side part of the tatami surface 3 is bend | folded by substantially U shape so that the side part of the tatami floor 12 may be covered. At that time, the tatami mat 3 is folded along the grooves 5 and 6 formed at the planned folding positions of the tatami mat 3. When bending, the grooves 5 and 6 are located at the inner corners of the tatami mat 3.

  Through the above steps a to c, as shown in FIG. 1 (d), the side portion of the tatami mat 3 is bent into a substantially U shape, and the side portion of the tatami floor 12 is wrapped by the U shape side portion. State is secured.

(Tatami surface processing equipment)
Next, the configuration and function of the processing apparatus 1 (grooving apparatus) used in the above-described step a will be described. This will be described with reference to FIG.

  The processing apparatus 1 shown in FIG. 4 is a processing apparatus used for manufacturing a tatami mat. Specifically, the processing apparatus 1 is a device for attaching the grooves 5 and 6 to the tatami mat 3 and simultaneously cutting the unnecessary length 9.

As shown in FIG.
A grooving means 21 for forming grooves along the planned folding position of the tatami surface;
A groove depth holding means 23 for keeping the depth of the grooves formed on the tatami surface constant;
A length cutting blade 25 for cutting unnecessary lengths from the tatami surface;
A rotating shaft 27 for rotating the grooving means and the length cutting blade;
A motor (not shown) for rotating the rotating shaft,
Etc.

  The grooving means 21 includes two rotary and coaxial grooving blades 31 and 32. In this embodiment, the grooving blades 31 and 32 are constituted by a rotary disk-shaped cutter having a predetermined-shaped blade on the outer periphery. By providing such two rotary grooving blades in an aligned state, grooves can be simultaneously formed at two planned folding positions (substantially U-shaped folding positions) of the tatami surface.

  On the outer periphery of the grooving blades 31 and 32 (disk-shaped cutter), a plurality of blades 35 having a predetermined shape are projected at equal intervals. The shape of the blade 35 provided in the grooving blades 31 and 32 is not particularly limited, but it is preferable that the curved surface can be provided with a curved concave groove. More preferably, the dimension is such that a groove having a depth of about 1 mm can be provided.

  The two grooving blades 31 and 32 are provided so that the interval (interval D1 shown in FIG. 4) can be freely adjusted. Thereby, since the space | interval of the parallel groove | channel can be adjusted freely, it can respond to the tatami floor of various thickness. That is, it becomes possible to deal with the production and mass production of tatami mats with various thicknesses.

  The length cutting blade 25 plays a role of cutting an unnecessary length at the same time as grooving the tatami mat. Since the length cutting blade 25 is provided so as to be able to freely adjust the interval (interval D2 shown in FIG. 4) with the grooving means, it can cope with processing of various sizes of tatami mats.

  The groove depth holding means 23 includes a bottom plate member 41 provided at the bottom of the processing apparatus 1. This groove depth holding means 23 can surely prevent the tatami surface from being cut at the expected folding position, and can maintain the optimum groove depth for folding.

  The bottom plate member 41 is formed with slits 51 and 52 through which the grooving blades 31 and 32 can partially protrude. Since the grooving blades 31 and 32 protrude from the slits 51 and 52 by a predetermined length, the groove depth formed on the tatami surface is always kept constant.

  The dimension in which the grooving blades 31 and 32 protrude from the slits 51 and 52 (dimension D3 shown in FIG. 4) can be freely adjusted.

(Excellent effect of the present invention)
According to the present invention described above, the grooves 5 and 6 can be easily attached to the folding position of the tatami mat 3, and as a result, the tatami mat which is difficult to be folded can be easily folded along the grooves 5 and 6 with labor saving. it can. In addition, by attaching grooves 5 and 6 in advance, the bent portion of the tatami surface 3 can be smoothly bent (without cracks, etc.), and the end of the tatami surface 3 (particularly the corner portion to be bent) can be finished finely. it can. Furthermore, since a tatami surface that is difficult to bend can be bent smoothly and easily, it is possible to meet the conventional demand for thin tatami mats.
