Machine to repairing shuttering panels and repair method
First Claim
1. Machine to repair formwork panels of a composite sandwich type having a core of plastic material and at least one structural skin, and an external film or finishing skin which comes in contact with concrete, characterized in that the machine comprises a peeling module which incorporates a battery of suction pads which are applied on an upper face of a previously heated external film, and are raised detaching and separating the film from the composite sandwich, as the panel advances horizontally, said suction pads being mounted on a horizontal support suspended from rails pertaining to a gantry which is displaced vertically by the action of a pneumatic cylinder with respect to a frame.

Abstract
Of application for sandwich type composite panels (1) formed by a synthetic core, a structural skin and an external film or finishing skin (3) which is in contact with the concrete. The machine comprises a peeling module (4) which incorporates a battery of suction pads (5) which are applied on the upper face of the previously heated external film (3) and are raised detaching it and separating it from the composite sandwich (2), said suction pads (5) being mounted on a horizontal support (6) suspended from some side rails (7) pertaining to a gantry (8) which is displaced vertically by the action of a pneumatic cylinder (10) with respect to a frame (9), having also means of displacement (9) on which the panel (1) is mounted which is moved in the horizontal direction facilitating, together with the vertical movement of the suction pads (5), the peeling of the formwork panel (1).

5. Procedure to repair formwork panels consisting of a composite sandwich having a core of plastic material and at least one structural skin, and an external film or finishing skin which comes in contact with concrete, the procedure comprising the following steps:
-
heating the panel by means of a hot plate head for fusing and deactivating adhesive present between the composite sandwich and the external film, applying suction pads on the external film of the panel, raising of the suction pads with simultaneous horizontal displacement of the panel, for detachment of the external film, cleaning of the composite sandwich, when the external film has been removed, by means of cleaning rollers, applying a new external film on the composite sandwich pressing and heating of the new external film by means of the hot plate head on the composite sandwich; and
withdrawal of the panel with the new film.
