Description

The present invention relates to a colored perforation device for applying a colorant such as ink to the inner peripheral surface of a hole formed in a sheet material to be cut, and a control method thereof.

Conventionally, it has been known that a sheet material such as a cloth is cut by a cutting machine or the like to cut out a part. Further, when cutting out such a part, a process called perforation may be performed in which a sheet material is perforated in order to serve as a mark when the parts are sewn together in a subsequent process. However, perforation that only perforates the sheet material has a problem that it is difficult to identify the perforated position when a large number of holes are formed in the fabric body such as lace fabric. Therefore, various methods for applying a colorant to the perforation position are known (see, for example, Patent Document 1). Patent Document 1 discloses a mechanism in which a hole is formed by a perforating member, and a coloring member is inserted therein to color the inner peripheral surface.

Patent No. 4467293

When the holes are hollowed out in advance, even if the same drilling member is used, with a material having many holes such as lace fabric, the hollowed-out object is difficult to maintain its shape and falls off from the inside of the drilling member. It may remain in the hole. In such a case, it is necessary to switch to a larger drilling member or the like so that the object to be drilled can maintain its shape. If the size of the hole is changed, the coloring performance on the inner peripheral surface of the hole is deteriorated, so that there arises a problem that the coloring member must be changed to a larger one.

An object of the present invention is to reliably color the inner peripheral surface of a hole formed in a sheet material by using a single coloring member.

The present invention has a table on which the sheet material is placed and a coloring member configured to be able to move and move in a plane relative to the table surface, and is formed at a preset perforation position of the sheet material. In a coloring type perforation device that applies a coloring agent to the inner peripheral surface of a hole by lowering and inserting the coloring member through the hole and then raising the coloring member and pulling it out from the hole.
It is characterized by including a movement control unit that controls the relative plane movement of the coloring member and the table so as to apply the coloring agent to the inner peripheral surface of the hole with the coloring member inserted through the hole. And.

Further, the present invention is characterized in that the shape of the hole is circular, and the relative planar movement between the coloring member and the table is a circular motion along the inner peripheral surface of the hole.

Further, the present invention is characterized in that the movement control unit raises the coloring member so as to pull it out from the hole while relatively moving the coloring member and the table in a plane.

Further, the present invention has a table on which the sheet material is placed and a coloring member configured to be able to move and move in a plane relative to the table surface, and is formed at a preset perforation position of the sheet material. In a coloring type perforation device that applies a coloring agent to the inner peripheral surface of a hole by lowering and inserting the coloring member through the hole, and then raising the coloring member and pulling it out from the hole.
It is characterized in that the coloring member and the table are relatively moved in a plane so as to apply a coloring agent to the inner peripheral surface of the hole with the coloring member inserted through the hole.

As described above, in the present invention, for coloring, the coloring agent is applied to the inner peripheral surface of the hole in a state where the coloring member is lowered and inserted into the hole at a preset perforation position of the sheet material. Since the member and the table are controlled to move relatively in a plane, the inner peripheral surface of the hole can be reliably colored.

Further, in the present invention, the relative plane movement of the coloring member and the table with respect to the circular hole is performed so as to form a circular motion along the inner peripheral surface of the hole, so that the inner peripheral surface of the hole is efficiently moved. Can be colored.

Further, in the present invention, since the coloring member is raised from the hole while relatively moving the coloring member and the table in a plane, the coloring member can be pulled out from the sheet material while coloring, and the working time can be shortened. .. Further, even when the height dimension of the portion to which the colorant is applied is shorter than the depth of the hole, the colorant can be applied to the inner peripheral surface while rising from the lower opening to the upper opening of the hole.

Reference numeral 31 denotes a bus, which is shown as one bus without distinguishing between a data bus and other instruction buses. In addition, it has an input / output interface (not shown), and can transfer data to and from external devices via various media and networks.

In addition to the above-mentioned X-direction drive mechanism 13 and Y-direction drive mechanism 14, the movement control unit 12 includes a drilling member 6, a coloring member 5, and a drilling member for raising and lowering the cutting blade with respect to the cutting table 3, respectively.

The perforation control unit 18 includes a perforation member rotation drive mechanism 19 and a perforated object discharge mechanism 20, and the coloring control unit 21 includes a coloring member rotation drive mechanism 22.

Reference numeral 26 denotes an operation unit, which receives an instruction from the operator to the cutting machine 40 (colored perforation device 1).

FIG. 3 is a flowchart showing the control of the colored perforation in the embodiment. Since the technique is the same as that of the known technique, the process of forming the holes 11 in the sheet material 10 laminated with the drilling member 6 is omitted. In this flowchart, after forming the holes 11 larger than the cross-sectional shape of the coloring member 5. The flow of is explained.

First, the process is started in step 1. The size of the hole 11 hollowed out by the drilling member 6 and the moving speed of the cutting head 2 are set in advance. In step 2, the coloring member 5 is aligned with the position of the hole 11 formed by the drilling member 6. In step 3, the coloring member 5 is lowered and inserted into the hole 11. FIG. 6A is a side sectional view showing a state at this time. Here, the shape of the coloring member 5 will be described with reference to FIG. FIGS. 4 (A) and 4 (B) show the appearance of the coloring member 5, and includes an absorber 34 in which a coloring agent such as ink is impregnated inside the member formed in a hollow cylindrical shape. ing. The colorant is supplied to the absorber 34 from a tank (not shown) located above the coloring member 5, and in the configuration of FIG. 4A, the colorant is supplied through a notch 32 provided in the cylindrical member in FIG. 4 (A). In the configuration of B), the coating is applied to the inner peripheral surface 35 of the hole 11 via a plurality of discharging portions 33 provided around the cylindrical member. Even if the portion without the notch in FIG. 4A abuts on the inner peripheral surface 35, the coloring agent cannot be applied. Therefore, in this configuration, the coloring member 5 is rotated about the axis by the coloring member rotation drive mechanism 22. Although it is necessary, it is easier to manufacture than the configuration shown in FIG. 4B, and the inner peripheral surface 35 is also improved in colorability by rotating. Note that L in FIG. 4 is the height dimension of the portion to which the colorant is applied.

In step 4, the coloring member 5 is moved in a plane inside the hole 11 to apply the coloring agent to the inner peripheral surface 35 of the hole 11. Here, FIG. 5A is a view showing the positional relationship between the hole 11 formed in the sheet material 10 and the coloring member 5 inserted into the hole 11 from above. Since the diameter D1 of the hole 11 is larger than the diameter D2 of the coloring member 5, it is difficult for the absorber 34 to touch the inner peripheral surface 35 simply by moving the coloring member 5 up and down with respect to the hole 11, and a coloring agent is sufficiently applied. Can not do it. Therefore, in the present invention, by moving the coloring member 5 in a plane while being inserted into the hole 11, the absorber 34 is brought into direct contact with the inner peripheral surface 35 to reliably apply the coloring agent. The plane movement may be reciprocated in the hole 11 in the front-back, left-right, and diagonal directions as shown in FIG. 5 (B), but as shown in FIG. 5 (C), it is circularly moved along the inner peripheral surface 35. Is preferable. FIG. 5D shows a locus when the coloring member 5 is circularly moved, and the coloring member 5 inserted through the center of the hole 11 is circularly moved by a half circle indicated by the locus of the arrow (1). The inner peripheral surface 35 is brought into contact with the inner peripheral surface 35, and then the circular motion of the trajectory of the arrow (2) is switched. After performing the desired number of circular motions, the locus of the circular motions for half a circumference indicated by the arrow (3) is returned to the center of the hole 11 again. By combining circular motions of different sizes in this way, the coloring member 5 can be continuously moved without stopping, and the time required for coloring can be shortened. The shape and size of the hole 11 may be included in the cutting data in advance, or may be specified by the user from the operation unit 26. The movement control unit 12 moves the coloring member 5 in a plane so as to abut on the inner peripheral surface of the hole 11 based on the input shape of the hole 11. It is preferable that the coloring member 5 is brought into contact with the inner peripheral surface 35 by pressure contact so that the colorant is sufficiently adhered.

In step 5, the coloring member 5 is raised and pulled out from the inside of the hole 11, and in step 6, the coloring type perforation process for one hole 11 is completed. Here, FIG. 6 (A) is a cross-sectional view of the state of FIG. 5 (C). The laminated sheet material 10 is placed on a cutting table 3 formed of a brush surface into which the cutting blade 7 can penetrate, and the coloring member 5 extends from the upper opening 36 to the lower opening 37 of the hole 11. The tip penetrates the brush surface while penetrating. In FIG. 6A, the depth of the hole 11 is larger than the height dimension (L) of the portion to which the colorant is applied, and the coloring member 5 is moved in a plane (circular motion) while rotating around an axis. It is not possible to color the periphery of the upper opening 36 of the hole 11 by itself. Therefore, by raising the coloring member 5 by the coloring member elevating mechanism 15 while moving the coloring member 5 in a plane, the inner peripheral surface 35 can be colored by the spiral locus shown in FIG. 6B.

In the above examples, the drilling member 6 and the coloring member 5 are provided on the common cutting head 2, but each may be provided with an individual drive source. Further, in the embodiment, the coloring member 5 is moved in a plane and moved up and down with respect to the cutting table 3, but the cutting table 3 is configured to be moved in a plane and moved up and down with respect to the fixed coloring member 5. Also, the mechanism for moving each part is arbitrary.

Further, although the circular hole 11 is used in the embodiment, a rectangular hole may be formed by pushing, for example, a hollow and rectangular punch blade that is not rotationally driven into the sheet material, and the shape of the hole is arbitrary. .. It is also possible to move the coloring member 5 in a plane along the inner peripheral surface of these holes to perform coloring.

If the holes 11 are formed after the parts are cut out from the sheet material 10, the laminated parts are not sufficiently fixed on the cutting table, so that there is a possibility that the parts are displaced at the time of drilling. Therefore, it is preferable that the holes 11 are formed in a state where the sheet material 10 is suction-fixed to the cutting table 3 and before the parts are cut out. However, if the individual sheet materials have sufficient weight and hardness and are not easily displaced, drilling may be performed before carrying the individual sheet material into the cutting machine or after cutting out the parts. In the embodiment, it has been described that the laminated sheet material 10 is marked, but it may be performed on one sheet material.
