Further, in the embodiment of the present invention, the position detecting unit may be configured to detect the lower limit position of the movable mold 300 and the lower limit position of the movable mold 300 as the operation start state of the finishing operation unit 900 Contact detecting means composed of the limit switch 110 and the probe 340 is applied but any element such as the non-contact type detecting means can be adopted as long as the element can detect the position of the upper limit and the lower limit of the movable mold 300 will be.

Hereinafter, the operation of the automation equipment for finishing work of the interior material according to the present invention will be described in detail.

The control unit 1000 controls the operation of the adsorption unit 400 located on the bottom surface portion 320 of the movable mold 300 in a state where the operation standby position which is the upper limit position of the movable mold 300 is detected via the position detection unit . The negative pressure provided through the negative pressure nozzle 410 of the adsorption unit 400 enables the semi-finished state interior material T to be effectively mounted on the bottom surface portion 320 of the movable mold 300.

The control unit 1000 precedes the wrapping operation of the fabric F with respect to the gentle curvature portion of the entire portion of the injection core C in the course of performing the wrapping operation by the finishing operation unit 900 , A more complete finishing operation can be performed by performing a series of sequential controls that allow the wrapping operation of the fabric F to follow a round portion with a relatively small curvature.

Then, when the wrapping operation by the finishing work unit 900 is completed, the control unit 1000 releases the operation of the finishing work unit 900 and cuts off the negative pressure supplied to the suction unit 400. [ Accordingly, the interior material T in the finished product state in which the wrapping operation is completed can be left on the upper portion of the seating metal mold 800 by its own weight without being adsorbed on the bottom surface portion 320 of the movable metal mold 300.

Next, the control unit 1000 controls the operation of the elevation unit 200 to raise the movable mold 300 to the initial standby position, thereby waiting for the subsequent wrapping operation for the other semi-finished products. In this process, the worker removes the interior material T in the finished product state remaining in the seating mold 800 by its own weight, and then removes the interior material T in the semi-finished product for finishing work T) may be newly installed.
