Abstract

An apparatus for manufacturing a surface-layered part comprises: a main support that supports a surface layer member to be placed under a base member; a pulling device arranged at a periphery of the main support, wherein the pulling device includes a pulling member that pulls an edge of the surface layer member, which is in a position away from the edge of the base member, outward with respect to the base member; a base member clamping device that fixedly clamps the surface layer member, having been pulled outward by the pulling member of the pulling device, against the main support via the base member placed over the surface layer member; and a relieving device that separates the pulling member from the edge of the surface layer member, which has been moved outward with respect to the base member by the pulling device, to allow the edge of the surface layer member to wrap around the edge of the base member by an elastic restoring force of the surface layer member, thereby integrating them; and a control device that drives and controls the base member clamping device, the pulling device, and the relieving device.

First claim

What is claimed is:

1. An apparatus for manufacturing a surface-layered part, comprising:
a main support that supports a surface layer member placed under a base member;
a pulling device at a periphery of the main support, wherein the pulling device includes comprises
a pulling member that pulls an edge of the surface layer member, the edge of the surface layer member being in a position away from an edge of the base member nearest the edge of the surface layer member, outward with respect to the base member,
a pulling mechanism configured to move the pulling member inward and outward with respect to an edge of a lip of the main support, and
a vertical movement mechanism configured to move the pulling mechanism vertically;

a base member clamping device that fixedly clamps the surface layer member, after having been pulled outward by the pulling member of the pulling device, against the main support via the base member placed over the surface layer member;
a relieving device that separates the pulling member from the edge of the surface layer member, the edge of the surface layer member having been moved outward with respect to the base member by the pulling device, to allow the edge of the surface layer member to wrap around the edge of the base member owing to an elastic restoring force of the surface layer member, thereby integrating the surface layer member and the base member; and
a control device configured to drive and control the base member clamping device, the pulling device, and the relieving device, and the control device is configured to execute instructions stored in memory to
drive the vertical movement mechanism to move the pulling mechanism toward the edge of the lip of the support member until the pulling member faces the edge of the surface layer member, then drive the pulling mechanism to move the pulling member in the outward direction with respect to the main support by a distance and pull the surface layer member outward with respect to the base member by hooking the pulling member on the edge of the surface layer member;
drive the vertical movement mechanism to move the pulling mechanism upward away from the edge of the lip of the support member and drive the pulling mechanism to move the pulling member in the outward direction by a distance in a state where the base member clamping device fixes and clamps the surface layer member to the support member via the base member, to pull the edge of the surface layer member in the outward direction further, then release the pulling member from the edge of the surface layer member; and
cause the edge of the surface layer member to wrap around the edge of the base member by an elastic restoring force of the surface layer member, and thereby the surface layer member is integrated with the base member.

2. The apparatus of claim 1 , further comprising:
a peripheral support along an edge of a lip of the main support, wherein the peripheral support serves as a bending restraint on the surface layer member as the surface layer member is being bent back outward over the peripheral support by the pulling member while being fixed, together with the base member, to the main support by the base member clamping device.

3. The apparatus of claim 2 , wherein the peripheral support comprises one or more round rail along the edge of the lip of the main support.

4. The apparatus of claim 1 , wherein:
the base member clamping device pushes the base member into the main support so that a peripheral edge of the base member comes in close contact with the surface layer member to thereby clamp the surface layer member.

5. The apparatus of claim 1 , wherein:
the pulling member is shaped to hook the edge of the surface layer member outward with respect to an edge of a lid of the support member and to be separated from the edge of the surface layer member away from the edge of the lid of the support member.

6. A method for manufacturing a surface-layered part using the apparatus of claim 1 , the method comprising:
first, placing the surface layer member on the main support;
second, pulling the edge of the surface layer member outward with respect to the base member by the pulling member;
third, fixedly clamping the surface layer member against the main support by the base member clamping device via the base member placed over the surface layer member; and
fourth, separating the pulling member from the edge of the surface layer member by the relieving device to allow the edge of the surface layer member to wrap around the edge of the base member owing to the elastic restoring force of the surface layer member, thereby integrating the surface layer member and the base member.
