Description

Detailed Description of the Invention (Field of Application in M Business) The present invention relates to an apparatus for manufacturing a skin member for a vehicle seat such as an automobile, and more specifically, to The present invention relates to an apparatus for manufacturing a skin member by welding the frame part using high frequency in orthogonal directions to join the body part and the frame part together.

(Prior Art) Conventionally, a method has been practiced in which a body part cut into a predetermined shape and a frame part are bonded together using a high-frequency welding machine to form a skin member. This method has the advantage that the bonding work can be performed easily and accurately. However, in the body part,
In the case where the end of the picture frame is joined to the end of the body part perpendicularly to the decorative weld pattern, the picture frame must be integrally joined to the body part after forming the welder pattern on the body part in advance. There was a problem that I couldn't do it. This is because the edges of the frame and body part are overlapped in the same direction so that the welded part that forms the joint is not exposed to the outside. Because the electrodes were in the way, it was not possible to simultaneously join the edges of the body part and the frame part in the direction orthogonal to the welder pattern of the body part. In addition, in the case where both ends of the body part and the frame part are bonded in parallel to the Welgie pattern, the above-mentioned problem does not occur because the electrode for forming the Welgie pattern does not get in the way.

(Purpose) Therefore, an object of the present invention is to form a welgie pattern on the body part and at the same time to join the ends of the body part and the frame part in a direction perpendicular to this pattern. be.

(#I formation) In the present invention, a joining electrode for joining both ends of the body part and the frame part, which is arranged in a direction perpendicular to the electrode for forming the Welgo pattern, is provided between the electrode for forming the pattern and the electrode for forming the pattern. It is characterized by being removably attached and close enough to create a gap equal to the thickness of the frame. Therefore, the frame part can be inserted into the gap between the pattern forming electrode and the bonding electrode and stacked with both ends facing the same direction, so that the body part and the frame part can be connected by the bonding electrode at the same time as the pattern is formed on the body part. Both terminals can be glued together.
