Claims

An apparatus for producing a sheet fusion body having a seal edge fused in a state where edges of a plurality of sheets overlap with each other,
A belt-like sheet laminate having a first surface and a second surface located on the opposite side and having a plurality of sheets including a resin material at least partially overlapped is supported on the first surface over the longitudinal direction. A support member;
An irradiation head disposed on the second surface side of the support member and having a lens for condensing laser light;
The support member has a slit-like opening that is long in the width direction of the sheet laminate, through which laser light irradiated from the second surface side can pass.
An air suction part for sucking air from the opening is disposed at a position on the first surface side of the support member so as to face the slit-like opening.
The sheet laminate supported on the first surface of the support member is irradiated with laser light from the second surface side along the slit-shaped opening, and the sheet laminate is divided in the width direction. At the same time, a sheet fusion body having the seal edge is manufactured by fusing the divided edges in an overlapping state, and the gas generated by the division is sucked and removed by the air suction part. The manufacturing apparatus for the fused sheet.

The support member has a first surface facing outward and a second surface facing inward, and is formed of a cylinder rotatable in one direction,
A pressurizing head for pressurizing the sheet laminate supported on the first surface of the support member;
The pressurizing head includes the air suction portion and can circulate along the peripheral surface of the support member in the same direction as the rotation direction of the support member and at the same speed as the peripheral speed of the support member. The apparatus for producing a sheet fusion body according to claim 1.

The air suction section, the extending in the same direction as the direction of extension of the slit-shaped opening, and a sheet fusing member of claim 1 or 2 having the slit-shaped opening arranged to face the air suction port Manufacturing equipment.

Before KiKa圧head includes a local pressure member having a locally pressurizing pressing surface pre Symbol said sheet stack supported on the first surface of the support member,
The local pressure member, said extending in the same direction as the direction of extension of the pressing surface is the air suction port, and as the pressurized pressure surface is positioned across the air suction port, to claim 3 which is disposed a pair The manufacturing apparatus of the sheet fusion body of description.

The pressurizing head further includes a pair of tension applying members that apply tension to the sheet laminate supported on the first surface of the support member,
The pair of tension applying members extends in the same direction as the air suction port extends, and is disposed so as to sandwich the pair of local pressure members.
The tension applying member is made of a flexible material, and a surface facing the sheet laminate is protruded from the pressurizing surface of the local pressurizing member. Prior to pressurizing the sheet laminate, the pressure surface is deformed so that the pair of tension applying members abut against the sheet laminate and are separated from each other, thereby being positioned between the pair of tension applying members. The apparatus for producing a sheet fusion body according to claim 4 , wherein tension is applied to the sheet laminate.

The peripheral surface of the front Symbol cylinder, the slit-shaped opening extending match the axial length direction parallel to the direction of the rotation axis of the cylinder is provided with a plurality at predetermined intervals in the circumferential direction of the cylindrical ,
Before KiKa圧head while the pressurizing head is circulating along the circumferential surface of the support member, said local pressing member of the pressurizing head is tangent to the first surface of the support member The apparatus for producing a sheet fusion body according to any one of claims 2 to 5, wherein the separation operation is repeated.

The pressurizing head has a hinge-shaped support portion at one end in the extending direction of the air suction portion, and swinging motion is possible in a plane passing through the rotation shaft of the support member with the support portion as a fulcrum. The apparatus for producing a sheet fusion body according to claim 6 , wherein the pressure head is adapted to move toward and away from the first surface of the support member.

The pressure head can reciprocate along the radial direction of the support member, whereby the pressure head makes contact with and separates from the first surface of the support member. The apparatus for producing a sheet fusion body according to claim 6 .

A method for producing a sheet fusion body having a seal edge fused in a state where edges of a plurality of sheets are overlapped,
A strip-shaped sheet laminate in which a plurality of sheets including at least a part of a resin material are stacked on a first surface of a support member having a first surface and a second surface located on the opposite side thereof over the longitudinal direction. Support,
Laser light is emitted from an irradiation head that is disposed on the second surface side of the support member and has a lens that collects laser light toward the sheet laminate supported on the first surface of the support member. Having a process,
Laser light is irradiated to the sheet laminate along a slit-like opening provided in the support member and extending in the width direction of the sheet laminate, and the sheet laminate is divided in the width direction. At the same time, a sheet fusion body having the sealing edge is manufactured by fusing the divided edges in an overlapping state, and the gas generated by the division is disposed on the first surface side of the support member. A method for producing a sheet fusion product that is sucked and removed by an air suction unit.

The sheet laminate supported on the first surface of the support member is locally pressurized at positions on both sides of the slit-shaped opening, and directed toward the sheet fusion body under the local pressure. The manufacturing method of the sheet fusion body of Claim 9 which irradiates a laser beam.

The sheet laminate supported on the first surface of the support member is pressed at positions on both sides of the slit-shaped opening, thereby tensioning the sheet laminate between two pressing positions. And grant
The sheet melt according to claim 10 , wherein the sheet laminate is locally pressurized at a position between each pressing position and the slit-like opening under a state where tension is applied to the sheet laminate. A manufacturing method of a kimono.
