  The above-mentioned plotter of Patent Document 1 performs printing on the surface of the processed material and also performs cutting from the surface of the processed material. By the way, as for the cutting blade generally used for a cutting | disconnection, as shown to Fig.7 (a), in a side view, the blade edge is diagonal with respect to the direction which a cutting blade advances. For this reason, when cutting is performed by inserting a cutting blade from the surface of the workpiece as shown in the drawing, the surface is excessively cut (overcut) when the cutting blade is advanced to a position where the back surface of the workpiece is cut off. It will be. In addition, the cutting blade has a wedge shape whose width becomes narrower toward the cutting edge in the thickness direction. Therefore, the cutting width when the workpiece is cut may be narrow on the back surface but wide on the surface. . That is, when a cutting blade is inserted from the printed surface, a necessary printed portion is deleted, and the appearance is impaired. In particular, when a thick workpiece is cut, the overcut length becomes longer and the cut width becomes wider. In addition, when trying to cut the workpiece into a curved shape, there may be a slight mark appearing on the side where the cutting blade is inserted, which also impairs the appearance. Further, when the single blade shown in FIG. 7B is used as the cutting blade, as shown in the drawing, the cutting blade being cut is once pulled out from the workpiece before the position where the cutting is desired to be finished, and then progressed so far. Rotate the cutting blade so that it is opposite to the direction, then insert it again into the workpiece from the position where you want to finish cutting, then move it in the opposite direction to the previous direction of travel and cut the remaining part By adopting this technique, overcutting can be prevented. However, there is a problem that the cutting process becomes complicated and it takes time to cut.

  On the other hand, the cutting plotter of Patent Document 2 performs a cutting operation from the back surface of the processed material, but printing on the processed material is performed by another apparatus. That is, since the work material must be transferred from the printing apparatus to the cutting plotter, it takes time and effort. In addition, when setting the printed processed material on the cutting plotter, variations in attachment are inevitable, and there is a difficulty in processing accuracy.

  An object of the present invention is to solve such problems, and it is possible to perform high-precision printing on a surface and cutting a predetermined shape on a processed material.

Accordingly, the printer head moving unit 80 can print an arbitrary character or image by moving the printer head 70 in the XY directions.

  Next, a method for printing on the workpiece W and cutting it into a predetermined shape using the cutting apparatus 1 of the present embodiment will be described.

  First, the workpiece W is placed on the belt 12 as shown in FIG. Next, the belt 12 is sandwiched by the holding unit 60, and the lower frame 31 and the upper frame 51 described with reference to FIGS. 2A and 4 are moved in the Y direction (−Y direction). Thereby, since the belt 12 moves forward, the workpiece W can be carried to a position where printing and cutting are possible. Thereafter, the printer head moving unit 80 is driven to move the printer head 70 to print a desired image, character, or the like. After that, the cutting head 20 is driven, and the cutting blade 21 is moved up and down while being oscillated in the vertical direction, so that the workpiece W enters from the back surface of the workpiece W. At this time, the blade receiving head 40 is driven to lower the roller 41 and press it against the surface of the workpiece W so that the workpiece W does not escape upward when the cutting blade 21 enters. I have to. Note that the gap 41 a of the blade receiving head 40 is located immediately above the cutting blade 21, so that even if the cutting blade 21 protrudes from the surface of the workpiece W, it does not contact the roller 41. Then, the workpiece W can be cut into a predetermined shape by driving the cutting head moving unit 30 and the blade receiving head moving unit 50 and moving the cutting head 20 and the blade receiving head 40 in the XY direction in synchronization. . Since the cutting blade 21 is inserted from the surface opposite to the printing surface of the workpiece W as shown in FIG. 7C, the printing surface even if the cutting blade 21 is moved to a position where the cutting is desired to be finished. Is never overcut. Further, when cutting the workpiece W, the holding of the belt 12 by the holding unit 60 is released. Thereby, even if the cutting head 20 and the blade receiving head 40 are moved, the belt 12 does not move. After the workpiece W is cut, the belt 12 is held again by the holding unit 60 and the lower frame 31 and the upper frame 51 are moved in the Y direction (+ Y direction). As a result, the belt 12 moves backward, so that the workpiece W that has been printed and cut can be carried out.

  As mentioned above, although one Embodiment of the cutting device according to this invention was described, this invention is not limited to embodiment mentioned above. For example, the belt 12 described above is clamped by the holding unit 60 and moves back and forth by moving the lower frame 31 and the upper frame 51 in the Y direction. However, the holding unit 60 is connected to the printer head moving unit 80. It may be provided.

  Further, if at least one of the four rollers 17a to 17d is driven like a roller 17a shown in FIG. 5B, the belt 12 can be moved back and forth regardless of the holding portion 60. Can do.

  Further, when the workpiece W can be set on the belt 12 without being carried in and out, for example, when the cutting device is small, both ends of the belt 12 are fixed as shown in FIG. Also good.

  In addition, the printer head moving unit 80 in the above-described embodiment can move the printer head 70 in the XY direction. However, when the printer head 70 is a line head extending in the X direction, Does not need to be moved in the X direction. Further, as shown in FIG. 6B, printing may be performed when the workpiece W is carried in by the belt 12 (may be carried out). In this case, the printer head 70 is moved in the Y direction. There is no need to let them.

  In the above-described embodiment, when the belt 12 is recessed to form the space S, the four rollers 13a to 13d are used as shown in FIG. Five or more may be used. Similarly, the number of the eight rollers 16a to 16h used for supporting the second belt 15 can be appropriately changed. Further, in the present embodiment, the belt 12 is employed as the placing means for placing the workpiece W. However, various types such as a long and flexible member that can be deformed similarly to the belt 12 can be used. For example, the belt 14 may be omitted and the tube 14 may be used as the placing means. In the cutting head moving unit 30 of the above-described embodiment, the lower frame 31 supports the rollers 13 a to 13 d that form the space S in the belt 12 and the rollers 16 a to 16 h that support the second belt 15. The space S is moved together with the cutting head 20, but another moving part (movable in the Y direction in synchronization with the cutting head moving part 30) different from the cutting head moving part 30 is provided. The rollers 13a to 13d and the rollers 16a to 16h may be provided in the moving part. In the above-described embodiment, the workpiece W is cut after printing. However, the workpiece W may be cut first. As described above, as long as the claims are followed, some of the constituent members may be omitted, the constituent members may be appropriately replaced between the above-described embodiments, and other configurations may be added. .
