Abstract

Closer of the front flap of boxes, in a sealing machine, of the type comprising a frame with its ground support legs, normally adjustable in height, and a means of driving, regulating and controlling the various organs of the machine, as well as as a table provided with means to facilitate the movement over it of the full boxes to be closed and sealed, said boxes moving rectilinearly and centeredly according to the longitudinal axis of said table of the machine and passing below and/or above the corresponding ones sealing means, which apply suitable adhesive means above and/or below, respectively, the current box, after folding the flaps of said box to its horizontal closing position, and the upper head of the machine referred to presents means for supplying and applying the aforementioned adhesive means, means for closing the lateral flaps of the box and means for closing the single front and rear track thereof, said head being mounted on a bridge transverse to the longitudinal axis of the machine, bridge that is in turn mounted on at least one side and vertical column, provided with means to guide and regulate the vertical displacement of said bridge, existing in the repeated machine means detectors of the arrival and, in his case, of the dimensions of the boxes to close and to seal; characterized in that it is constituted by a longitudinal lever and preferably provided with a flat area for contact with the upper part of the corresponding box, whose lever is articulated, by a point thereof located above said flat area, in the front and lower part of said upper head; because the power arm of this lever is articulated to the rod of a cylinder, in turn tilting in said head and said lever is driven by an elastic means towards a downward and backward inclined position, so that the displacement of a box on the table of the sealing machine causes the push of the resistance arm and, consequently, the rotation of the lever to a horizontal position; and because there is a valve fixed to the repeated upper head, which is operated by the said rotation of the lever, through a convenient means, which produces the activation of the aforementioned cylinder and the maintenance of the lever in a horizontal position, all this in relation to the detection means of the arrival of the boxes to be sealed and sealed.
