Problems solved by technology

When such a raw material is mechanically cut by a cutting blade, the fibers are cut at the cut end, etc., which becomes the starting point of tissue destruction, and if an external force is applied, there is a risk of thread slipping such that the damage of the tissue is likely to expand.

Embodiment 1

[0035] figure 1 (a) The structure of the main part of the cutting machine 1 which is Example 1 of this invention is shown in simplified form. The cutting machine 1 includes a cutting table 2 and a cutting blade 3 provided on a cutting head movable along the surface of the cutting table 2 . The cutting blade 3 is, for example, provided with a linear blade 3a in a direction perpendicular to the surface of the cutting table 2, reciprocates in this direction, and at the same time, cuts and is placed on the cutting table 2 by the blade portion 3b having the blade 3a as the front end. Sheet material 4. In the cutting table 2 , for example, a vacuum suction device is installed below, and the sheet material 4 is sucked and held by the surface of the cutting table 2 . During cutting, the cutting blade 3 penetrates into the surface of the cutting table 2 with a blade width W including the blade portion 3b and the blade portion 3c. The surface of the cutting table 2 is formed of brist...

Embodiment 2

[0053] exist Figure 6 In the cutting machine 21 shown in (a), the sheet material 4 is cut by the cutting blade 23 of the blade width W2 which is used fixedly without moving up and down. Although the blade 23a is inclined relative to the surface of the cutting table 2, it can be used with figure 1 The same heating member 5 heats the periphery of the blade 23a including the front in the cutting direction to perform off-line locking. In the cutting blade 23, if the sharpness of the blade 23a becomes poor, the cutting blade 23 is raised and lowered to change the position of the blade 23a within the blade width W2. When using to the vicinity of the lower end of the cutting blade 23 , the heating surface 6 may extend to the left in the drawing to surround the entire cutting blade 3 from the outside.

Embodiment 3

[0055] exist Figure 6 Also in the cutting machine 31 shown in (b), the sheet material 4 is cut by the cutting blade 33 which is used fixedly without moving up and down. In the cutting blade 33, blades 33a are provided on both sides of the lower end within the blade width W3. The heating member 5 is provided in front of the blade 33a used for cutting. When changing the direction of the blade 33a used for cutting, it is only necessary to replace the cutting blade 33 .

Abstract

The invention provides a cutting machine that can cut off thermoplastic sheet material while performing off-line locking. A heating member (5) has a heating surface (6) that is in contact with the surface of a sheet material (4) when cutting the thermoplastic sheet material (4) on a cutting table (2). The heating surface (6) can heat a scope to the front side of a blade (3a) of a cutting knife (3), so that the sheet material (4) can be bonded locally. The heating surface (6) can heat the cutting part of the cutting knife (3) first, and perform off-line locking by bonding before cutting. At the same time, the sheet material (4) is cut by the cutting knife (3).

Description

technical field [0001] The present invention relates to a cutting machine for cutting sheet material with a cutting blade. Background technique [0002] Conventionally, sheet materials of various raw materials were cut by cutting machines. In recent years, there has also been a need to cut nylon textiles for air bags used to ensure the safety of car passengers. As air bag base fabrics, non-coated materials that are not coated with synthetic rubber resins are frequently used. If such a raw material is mechanically cut by a cutting blade, the fiber is cut at the cut end or the like, which becomes the starting point of tissue destruction, and if an external force is applied, there is a risk of thread slipping such that the damage of the tissue is easy to expand. Since nylon fibers are thermoplastic fibers, if they are thermally fused instead of mechanically cut, the fibers at the ends will be welded and will not be disconnected. As an example of using heating, cutting is per...
