DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
In the laminate cutting device disclosed in Japanese Patent No. 13836, a knife-shaped cutter penetrates a laminate that is compressed and held on a support surface by intake air, and the tip of the cutter is located near the support surface of the support member. Because it is a cantilever type cutter that also penetrates,
At the time of cutting, the tip of the cutter is distorted due to the resistance of the laminate and the supporting member, which makes it difficult to obtain a highly accurate cut product. In addition, there are some that use a band saw type cutter as a cutting tool, but at the time of cutting it is necessary to cut the laminate and the supporting member at the same time by the cutter and replace the supporting member at a high frequency, resulting in a good operating rate. There was a problem that it did not exist.

Further, in the cutting device for a laminate disclosed in Japanese Patent Laid-Open No. 1-306200, when the sheet material constituting the laminate has a low air permeability, the intake ports of the intake duct are provided on both side surfaces of these sheet materials. Even if the sheet is aspirated by contacting with each other, the close contact force of the sheet material of each layer is weak at a position away from the intake port, the cutting state of the cutter breaks the laminated state, and a highly accurate cut product cannot be obtained. Then, in the case where the intake port of the intake duct is brought into contact with both side surfaces of the laminate, it is necessary to move the intake duct laterally each time the width of the laminate changes.
There is a problem in that it takes time and the operating rate decreases.

Further, in the present invention, since the holding belt has the air passage formed between the non-air-permeable member of the lower layer and the air-permeable member of the upper layer, from the entire lower surface of the laminate placed on the holding belt. Air can be sucked almost uniformly, so even when the air permeability of the laminate is sufficient, even if the air permeability is low, the entire laminate can be uniformly compressed and held securely on the holding belt. The cutting resistance of the cutter does not disturb the laminated state such as the sheet material that makes up the laminate is displaced, and the cutter has both upper and lower holding types for cutting. Even when cutting a complicated shape, the deformation due to the distortion of the cutter is small, and a highly accurate cut product can be easily obtained.

Further, since the holding belt is not cut at the tip of the cutter, it is not necessary to replace it, and it is not necessary to move the intake duct in the lateral direction even if the width of the laminate is changed. And the cut product can be obtained efficiently.

When the movable concave portion is moved, the supporting plate supporting the lower surface of the holding belt in front of the traveling body moves the traveling body to bring the cam plate fixed to the traveling body into proximity by an appropriate means. Upon detection, the brake is released and the descent is possible. Then, as the traveling body travels, the roller pivotally attached to the support plate engages with the cam groove of the cam plate, and as the traveling body travels, the support plate descends while maintaining the horizontal state, and moves below the movable concave portion. . The support plate located below the movable concave portion is guided by the cam groove as the traveling body travels and ascends from the rear one, and when it is separated from the cam plate, the support plate lower surface of the holding belt is supported. In this state, the brake stops the brake releasing operation, so that the brake is locked at the raised position and the locked state is maintained. Therefore, as the movable recess moves, the supporting plate located below the movable recess changes only. Only the supporting plate corresponding to the cam plate in the vertical direction is positioned below the movable recess. Always support.

In the present invention, in the above-mentioned embodiment,
Although the driving force is transmitted from the electric motor by using the timing belt and the toothed pulley, the driving force may be transmitted by using a ball screw shaft, a chain or the like instead of these. In the present invention, if necessary for work, a sheet of air-permeable material or a sheet of paper having a large number of air holes is placed on the lower surface of the laminate as an underlay paper, and is supported together with the laminate on the holding belt through the underlay paper. However, cutting may be performed.

As described above, the laminate cutting apparatus according to the present invention places a laminate of sheet material such as cloth at a predetermined position on the laminate holding belt, and the laminate and the upper surface of the holding belt. Almost all the part exposed to the atmosphere is covered with a flexible non-breathable sheet, and in this state, from the air inlet of the air intake duct to the non-air permeable member of the lower layer of the holding belt and the air permeable member of the upper layer. By inhaling air through the air passage formed between the air-permeable member and the breathable member, the laminate and the non-breathable sheet are held on the holding belt, and the entire laminate is uniformly compressed.

While maintaining this state, the knife-shaped cutter is penetrated through the non-breathable sheet and the laminate to allow the tip of the cutter to penetrate into and be supported by the cutter receiving tube, and the cutter head provided in the traveling body in the lateral direction. By moving and running the running body in the vertical direction, the movable recess formed in the holding belt and the cutter receiving cylinder disposed in the moving recess are moved in the vertical and horizontal directions in accordance with the running body and the cutter head to form a laminate. To cut.

Further, in the present invention, since the holding belt has the air passage formed between the non-air-permeable member of the lower layer and the air-permeable member of the upper layer, the whole surface of the lower surface of the laminate placed on the holding belt is Air can be sucked almost uniformly, so even when the air permeability of the laminate is sufficient, even if the air permeability is low, the entire laminate can be uniformly compressed and held securely on the holding belt. The cutting resistance of the cutter does not disturb the laminated state such as the sheet material that makes up the laminate is displaced, and the cutter has both upper and lower holding types for cutting. Even when cutting a complicated shape, the deformation due to the distortion of the cutter is small, and a highly accurate cut product can be easily obtained.
