Description

  The present invention relates to a cutting device for a tatami floor having a size of a semi-tatami mat, for example, used for an edge-less tatami mat.

  2. Description of the Related Art Conventionally, for example, a semi-tatami tatami mat such as a rimless tatami mat for a semi-tatami mat, such as a Ryukyu tatami mat, has been widely used recently because of interior interior characteristics.

  When manufacturing a semi-tatami mat such as an edgeless tatami mat for such a semi-tatami mat, before sewing the tatami mat or attaching the tatami mat, the tatami floor cutting device is used to cut the upper and lower tatami floors. It is cut into a predetermined size that matches the size of the room where the side is laid.

  By the way, as a conventional tatami floor cutting apparatus, for example, Japanese Patent Laid-Open No. 9-294886 discloses a tatami mat manufacturing system.

  Among them, a scissor cutting machine that cuts the buttock of the tatami floor, a tatami mating machine that lays the tatami mat on the tatami floor and sews both sides, and flat stab that performs top and bottom front stabs and cuts. A machine is disclosed.

  This Patent Document 2 (Japanese Patent Laid-Open No. 9-250229) discloses a mechanism for cutting a tatami floor on the heel side and cutting it into a predetermined dimension.

  Further, Patent Document 3 (Japanese Patent Laid-Open No. 4-216901) discloses a plate-shaped cutting apparatus that turns a rectangular plate-like body accurately by 90 ° and cuts four sides of the rectangular plate-like body. Has been.

  That is, in Patent Document 3, a pair of cutting tools facing in the width direction are provided so as to be able to advance and retreat in the width direction across the central portion of the linear conveyance rail extending in the front-rear direction.

  The plate-like conveyance vehicle that reciprocates the conveyance rail is provided with a turning support base configured to sandwich the center of the plate-like body up and down and turn 90 degrees horizontally.

JP-A-9-294886 JP-A-9-250229 JP-A-4-216901

  By the way, in the case of cutting four sides of a square-shaped semi-tatami mat floor using the tatami mat manufacturing system disclosed in Patent Document 1, the operator turns the tatami floor by 90 °, The process of cutting twice is required.

  Also in Patent Document 2, when cutting four sides of a semi-tatami tatami floor, an operator needs to turn the tatami floor 90 degrees and cut twice with a scissors cutting machine.

  Therefore, in both cases of Patent Document 1 and Patent Document 2, it is necessary to manually turn the tatami floor, which is troublesome and costly.

  By the way, as shown in FIG. 18, the room sill is not necessarily 100% square or rectangular. Therefore, when tatami is spread, the upper front side is finished in a straight line, and the upper front side and the heel side on the side that is not hazy. It is necessary that the angle formed by

  In this case, as shown in FIG. 18, the lower front side is squeezed along the sill to finish and lay the tatami mat, so that the shape of the tatami mat in plan view is the opposite side of the upper front side and the lower side. The front side is not completely parallel when there is a habit.

  In this case, since the straightness of each side of the unfinished tatami floor is unstable, for example, two cutting operations as shown in FIG. 6 are required.

  For example, as shown in FIG. 6A, a case will be described in which a finished tatami floor 300 shown by a dotted line is cut from an unfinished tatami floor 200 shown by a solid line.

  That is, as shown in FIG. 6A, with respect to the upper front side D0 of the finished tatami floor 300, one heel side D2 is perpendicular (no habit) and the other heel side D3 has a habit, The case where the front side D0 is not perpendicular to the heel side D3 is shown.

  In this case, after cutting the heel sides D2 and D3 in the first cutting, the tatami floor is turned 90 ° clockwise as shown by the arrow in FIG. Cut the front side D1.

  However, in either case of Patent Document 1 or Patent Document 2, the operator can use two sides (upper front side) that sandwich at least a right angle of the unfinished tatami floor (in the case of FIG. 6, the upper front side D0 and the heel side D2). ), It is necessary to turn the tatami floor 90 °, but there is a possibility that the turning direction may be wrong.

  Further, Patent Document 1 discloses a plate-shaped body cutting device disclosed in Patent Document 3, which rotates a rectangular plate-shaped body precisely 90 ° and cuts four sides of the rectangular plate-shaped body. When applied to a tatami mat manufacturing system and configured to cut by turning 90 °, the installation space for the device increases, and a precise and complicated mechanism for turning 90 ° accurately is required. It will be large and costly.

  Further, the tatami floor 200 is formed with a tatami floor seam F that is spaced apart by a predetermined distance. Depending on the position of the upper front cutting line that cuts the upper front side D0, this cutting line may be a seam of the tatami floor. It overlaps with F and cuts the sewing thread and overlaps the sewing hole.

  In addition, for example, as shown in FIG. 18, this problem also occurs in the lower front cutting line on the lower front side in the case of a square tatami floor without a habit, such as the central part of the room. .

  As a result, jagged irregularities occur on the surface and side surfaces of the upper front side D0, and when the tatami mat is sewn or pasted on the surface of the tatami floor that has finished the tatami mat, the upper front side D0 becomes uneven and looks bad. And the linearity of the upper front side will deteriorate, and when the tatami mats are laid down, gaps will be opened.

  In view of such a current situation, the present invention, when manufacturing a semi-tatami mat such as an edgeless tatami mat for semi-tatami mats, before sewing the tatami mat or attaching the tatami mat, by using a tatami floor cutting device, An object of the present invention is to provide a tatami floor cutting device capable of cutting into a predetermined size that matches the size of the room in which the upper front side, the lower front side, and the heel side are laid.

  In addition, the present invention eliminates the need for complicated swiveling work of the tatami floor by hand, reduces the number of work steps, does not require labor and cost, and does not cause a mistake in the swiveling direction. An object of the present invention is to provide a tatami floor cutting device that does not increase in size.

  Further, the present invention is such that the upper front side cutting line and the lower front side cutting line do not overlap the seam F of the tatami floor, do not cut the sewing thread, do not overlap the sewing hole, and When the surface of the finished tatami floor is sewn or pasted, the upper front and lower front sides do not become uneven, the appearance is good, the upper front side has good linearity, and when the tatami is laid down An object of the present invention is to provide a tatami floor cutting device in which no gap is left.
