Abstract

Press for gluing shoe soles, characterized essentially because the press performance is carried out by means of a hydro-pneumatic circuit which is integrated by an input reducer with filter and lubricant, which connects the external pneumatic network with a three-way distributor, two of they are destined to the feeding of electrically controlled solenoid valves by a timer that will regulate the pressing time, each one of which electrovalves determines by means of its excitation the action of a press cylinder and a hydro-pneumatic converter in communication with the cylinder, as well as the control of a non-return valve located between the converter and the cylinder and of a membrane valve, which is fed through a pressure reducer through the third way of the distributor and is communicated through a quick exhaust valve with a pad inflatable provided at the end of the cylinder plunger of pressing, all arranged in such a way that when the press is at rest each solenoid valve keeps its input in communication with the pressing cylinder whose piston will be picked up by the pneumatic pressure inside, and in communication with the check valve and the membrane valve carrying out a pneumatic pilot, while the output of the aforementioned solenoid valve will be communicated with the converter that will be full of oil, which when the solenoid valve is activated when the press is operated, will displace the oil inside it. Pressing cylinder whose piston will rise to verify its entire course, at which time to decrease the pneumatic pressure that piloted the membrane valve, it will feed the pad through a quick exhaust valve, inflating the aforementioned pad and making more effective the pressing.
