Abstract

Press for gluing shoe soles, which being those used in the gluing of shoe soles and those involving a hydropneumatic lifting cylinder and two tires for the positioning of the shoe, is essentially characterized in that and for the control of these cylinders it has been equipped with a hydropneumatic circuit integrated by an input, with filter and lubricator, which connects the pneumatic external network with a three-way distributor, one of which is intended for the supply of a solenoid valve electrically piloted by a timer that regulates the pressing time, which solenoid valve determines by its excitation, the performance of a hydro-pneumatic converter in communication through the cylinder of a multiplier, with the lifting cylinder; in such a way that this multiplier is pneumatically operated by another valve fed from the three-way distributor and piloted pneumatically from a membrane valve, according to its ends, which pneumatically controls two other cylinders intended for fastening the shoe to be manufactured, counting likewise and for the control of said membrane valve with a pneumatic conduction from the drive of the lifting cylinder; all arranged in such a way that when the lifting cylinder is at rest the solenoid valve keeps its input in communication with the lifting cylinder, whose piston will be picked up by the internal pressure and in communication with the membrane valve, making a pilot pneumatic, while the output of the aforementioned solenoid valve will be communicated with the converter that will be partially filled with oil, which when the solenoid valve is energized when the device is put into operation, will move the oil from its interior to the lift cylinder through the cylinder of smaller section filled with multiplier oil, whose piston corresponding to the lifting cylinder will ascend until it is fully verified, at which time and by sealing the pneumatic supply to the membrane valve, the pressure inside it that piloted it decreases. Which causes it to feed on the one hand to a valve in charged for the control of the multiplier and for the actuation of the positioning cylinders by another, in which case the actuation of the multiplier produces an increase in pressure in the lifting cylinder and consequently a greater tightening thereof in the soles of the shoes to be glued.
