And a cutting blade Mh attached to the lower end of the elevating and moving unit Mg, and the cutting material Mh can be moved up and down in any direction at a constant pitch to cut the processing material P. In addition, near the cutting blade Mh, the cutting blade Mh
A detection mechanism Mi is provided for detecting the position of the processing material P below and automatically driving and correcting the pulse motors Mb and Md and the servo motor Mf in cooperation with a controller (not shown).

Further, the cutting and processing apparatus M includes a transport film feeding roller M1 on which the transport film Mk is wound and a transport film winding roller Mm for winding the transport film Mk.
Are arranged below the cutting blade Mh with a space therebetween, and the processing material P is placed on the transport film Mk so as to be continuously moved and supplied immediately below the cutting blade Mh.

Further, the cutting apparatus M includes a conveying film feeding roller M1 and a conveying film winding roller Mm.
The cutting board Mn is installed just below the cutting blade Mh at the center of the fixed base Mj arranged along the lower surface of the transport film Mk between the cutting board Mk, and the cutting board Mn can be moved up and down by the lifting unit Mo.
The working material P can be set on a constant working surface by raising and lowering n.

In such a cutting apparatus M, the cutting blade Mh is attached to the cutter holder Mp, the cutter holder Mp is attached to the box-shaped tool box Mr, and the tool box Mr is attached to the lower end of the ascending / descending movement unit Mg. There is. The tool box Mr is provided with a stripper Ms that slides along the cutter holder Mp to move the cutting blade Mh in and out, and includes a spring Mt that elastically biases the cutting blade Mh in a direction to expose the cutting blade Mh.
The g is provided with a cylinder rod Mu that is responsive to air pressure and oil pressure that applies a pressing force to the stripper Ms in the direction opposite to the spring Mt. Therefore, by controlling the pressing force of the cylinder rod Mu, the processing material P
The pressing force of the stripper P with respect to can be adjusted, and the cutting blade Mh can be projected and retracted at an arbitrary position for vertical movement.

In contrast to the cutting apparatus M, the cutting blade cleaning mechanism C is mounted on the mounting portion 1 which is fixed to the horizontal linear moving portion Me and vertically installed along the elevating and moving portion Mg. It is composed of a road 2 and a traveling body 3 that travels on the moving road 2.

The moving path 2 is arranged at the position of the ascending dead center of the cutting blade Mh along the lengthwise direction of the cutting blade Mh, and below the guide shaft 21 in parallel with the guide shaft 21. The traveling shaft 22 is provided. The guide shaft 21 and the traveling shaft 22 are longer than the cutting blade Mh.

The traveling body 3 includes a guide cylinder 31 which fits on the guide shaft 21 and slides, a rodless cylinder 32 which is hung on the guide cylinder 31 and fits on the traveling shaft 22 to travel, and a rodless cylinder 32. The wiper 33 is made of an elastic material such as nitrile rubber and is supported by the wiper 33 to sandwich the cutting blade Mh from both sides, and a dish-shaped foreign matter receiver 34 supported below the wiper 33.

According to such an embodiment, in order for the cutting blade cleaning mechanism C to function, when the cutting blade Mh reaches the ascending dead center, the pressing force of the cylinder rod Mu is controlled and the stripper P is slid. Exposing the cutting blade Mh and moving path 2
The traveling body 3 is caused to travel. When the traveling body 3 travels, the wiping unit 33 sandwiching the cutting blade Mh from both sides moves in the blade length direction of the cutting blade Mh, and is formed of an elastic material.
The foreign matter D adhering to the cutting blade Mh can be efficiently scraped off by the wiping unit 33 that is in contact with the high pressure. The foreign matter D thus scraped off is stored in the foreign matter receiver 34 below the wiping unit 33 and is prevented from falling onto the processing material P. When the cutting blade Mh is moved up and down, the traveling body 3 can be retracted from the cutting blade Mh by using the moving path 2 formed longer than the blade length of the cutting blade Mh. It can be avoided that the cleaning mechanism C acts as a resistance to the vertical movement of the cutting blade Mh.

The above-mentioned operation of the cutting blade cleaning mechanism C is a linear movement operation of the traveling body 3 and can be quickly performed when the cutting blade Mh reaches the ascending dead center. It is not necessary to stop the servo motor Mf that drives the vertical movement of the cutting blade Mh (the vertical movement unit Mg) in response to the operation. Further, the cutting blade cleaning mechanism C is not necessarily required to operate when the cutting blade Mh moves upward, and is set to operate once for several times the cutting blade Mh moves up, or the cutting blade Mh is cut. It is also possible to detect the adhesion state of the foreign matter D on the blade Mh from the change in the time required for the up-and-down movement due to the deterioration of the sharpness of the cutting blade Mh and set it to automatically operate. You can also choose to drive or reciprocate.

In addition to the illustrated embodiment, the running body 3 may be driven by a screw, a motor or the like.
