Manufacturing apparatus and method for stitched surface leather.

Abstract

To suppress positional deviation in stitches in a skin.SOLUTION: A manufacturing device of skin with stitch includes: a skin receiving jig 1 having a three-dimensional-shaped receiving surface 7 for receiving a three-dimensional-shaped skin 40, and a fixing device (adsorption device) for fixing the skin 40 which the receiving surface 7 has received; a sewing machine 20 for sewing stitches on the skin 40; a robot 30 for taking out the skin from the skin receiving jig 1, moving it to the sewing machine 20 and feed-driving it; and a control device for controlling the sewing machine 20 and the robot 30.SELECTED DRAWING: Figure 1

Claims

[Claim 1] A skin receiving jig comprising a three-dimensional receiving surface for receiving a three-dimensional skin, and a fixing device for fixing the skin received by the receiving surface, A positional misalignment detection device that detects the positional misalignment of the surface received by the receiving surface relative to a reference position on the receiving surface, A sewing machine that stitches onto the surface, A robot that removes the epidermis from the epidermis receiving jig, moves it to the sewing machine, and drives the feed mechanism, A control device that controls the sewing machine and the robot, A manufacturing apparatus for stitched epidermis, including the stitching. [Claim 2] The apparatus for manufacturing a stitched epidermis according to claim 1, wherein the fixing device is an adsorption device that adsorbs multiple locations on the epidermis. [Claim 3] The apparatus for manufacturing stitched skin according to claim 2, wherein the suction device comprises a suction pad facing the receiving surface and a depressurizing device connected to the suction pad. [Claim 4] The apparatus for manufacturing stitched skin according to claim 1, wherein the positional misalignment detection device uses a camera provided on the skin receiving jig. [Claim 5] The apparatus for manufacturing stitched epidermis according to claim 1, wherein the positional displacement detection device recognizes multiple characteristic areas of the epidermis captured by the camera. [Claim 6] The apparatus for manufacturing stitched skin according to claim 1, wherein the control device does not operate the robot and sewing machine when the misalignment detection device detects a misalignment greater than a set value. [Claim 7] The apparatus for manufacturing a stitched skin according to claim 1, wherein the control device reflects the positional deviation detected by the positional deviation detection device into the sewing program. [Claim 8] The apparatus for manufacturing stitched skins according to claim 1, wherein the receiving surface of the skin receiving jig is made of metal. [Claim 9] The apparatus for manufacturing a stitched skin according to claim 1, wherein the receiving surface of the skin receiving jig is made of resin. [Claim 10] The three-dimensional skin is supported by the three-dimensional receiving surface of the skin receiving jig, and the skin supported by the receiving surface is fixed by the fixing device of the skin receiving jig. The misalignment of the surface layer received by the receiving surface relative to a reference position on the receiving surface is detected by a misalignment detection device. The robot removes the skin from the skin receiving jig, moves it to the sewing machine, and drives the feed mechanism. A method for manufacturing stitched leather, in which a sewing machine sews stitches onto the leather surface.
