2. Description of the Related Art Conventionally, as a processing material feeding mechanism, for example, there has been proposed by the present applicant as Japanese Patent Application No. 3-138058.

The conventional feed mechanism of the working material according to the prior proposal of the present applicant is one mechanism constituting a cutting processing device for continuously cutting the ceramic green sheet or the like in a plurality of directions. The belt-shaped conveying member wound on the winding roll is arranged so as to move horizontally, and the processing material is placed on the horizontally-moving belt-shaped conveying member and fed to the machining work unit composed of a cutting blade. is there.

In the conventional feed mechanism for a processed material according to the prior proposal of the present applicant, since the belt-shaped conveying member is formed of the non-air-permeable synthetic resin film, it is placed on the belt-shaped conveying member. There is a problem that the processing material is likely to be displaced on the belt-shaped conveying member.

[0005]

The present invention has been made in consideration of the above-mentioned problems, and is a mechanism for feeding a working material capable of effectively preventing a positional deviation of the working material on a belt-shaped conveying member. The challenge is to provide.

[0006]

In order to solve the above-mentioned problems, in the processing material feeding mechanism according to the present invention, the belt-shaped conveying member wound around the feeding roll and wound around the winding roll moves horizontally. In a processing material feeding mechanism in which a processing material is placed on a horizontally moving belt-shaped conveying member and is fed to a machining unit, the belt-shaped conveying member is formed of a Japanese paper or a Japanese paper-like breathable material, and the processing material is A means characterized in that it can be adsorbed to the belt-shaped conveying member by vacuum is adopted.

[0007]

According to the above-mentioned means, since the belt-shaped conveying member is made of the Japanese paper or the air-permeable material like Japanese paper, the vacuum is applied from the lower side of the belt-shaped conveying member to suck and hold the processing material on the belt-shaped conveying member. Therefore, the problem of providing a processing material feeding mechanism capable of effectively preventing the positional deviation of the processing material on the belt-shaped conveying member is solved.

The processing material P can be cut and processed by moving up and down in the direction of with a constant pitch. In addition, in the vicinity of the cutting blade Mh, the position of the processing material P under the cutting blade Mh is detected and the pulse motors Mb, Md, the servo motor M are linked with a controller (not shown).
A detection mechanism Mi that automatically drives and corrects f and a cleaning mechanism Mj that removes foreign matter attached to the cutting blade Mh are provided.

Further, the cutting processing device M includes a cutting blade M.
A work table Mk is installed below h. The work table Mk includes a fixed base Mka horizontally installed below the cutting blade Mh, a cutting board Mkb vertically movable just below the cutting blade Mh at the center of the fixed base Mka, and a cutting board Mk.
and a raising / lowering section Mkc for raising / lowering the cutting board Mkb provided below the kb. The fixed table Mka forms a fixed feed guide surface for the processing material P, and the raising / lowering section Mkc raises / lowers the cutting board Mkb. A variable working surface of the working material P corresponding to the thickness of the work material is formed.

In this embodiment, which is provided in the cutting machine M, the work table Mk is provided with a feeding roll 2 which is arranged at one end of a fixed base Mka of the work table Mk and on which a belt-shaped conveying member 1 is wound. And a winding roll 3 around which the belt-shaped transport member 1 arranged on the other end side of the fixed base Mka is wound, and the belt-shaped transport member 1 wound around the feeding roll 2 and wound around the winding roll 3 is machined. Section below the cutting blade Mh is horizontally moved along the fixed table Mka of the work table Mk, and the processing material P is placed on the horizontally moving strip-shaped conveying member 1 and is fed below the cutting blade Mh which is a machining section. I am doing it. The feeding roll 2, the winding roll 3 and the like are supported inside lids 4 and 5 that are formed to be openable and closable on the side of the work table Mk, and the feeding rolls 2 and 5 are opened and closed by opening and closing the lids 4 and 5. The take-up roll 3 and the like can be hidden below the work table Mk or exposed from the work table Mk.

The strip-shaped conveying member 1 of this embodiment is made of Japanese paper. Washi has a thinness and a considerably high toughness similar to a synthetic resin film, is not inferior in terms of material quality on the conveying surface of the processed material P, and is characterized by having air permeability. It is also possible to form the entire band-shaped conveying member 1 with a uniform Japanese paper, or to form reinforced ears along the edges. Further, in addition to Japanese paper, it is also possible to reinforced and mix synthetic resin fibers and the like.

Furthermore, in this embodiment, a suction mechanism 6 for the processing material P utilizing the following vacuum is provided.

The suction mechanism 6 cuts the processing material P, the periphery of which is surrounded by the guide frame F, into a grid-like chip portion P'to collect the chip portion P'and the guide frame F separately. It corresponds to the configuration described above, and includes a holding portion 61 and a separating portion 62. The holding portion 61 is provided with the cutting board Mk.
