Definitions

  • the invention concerns a device to connect plugs to the dies of presses used for the formation of ceramic tiles, comprising an electric circuit based on the exploitation of the energy supplied by two fields with permanent magnet, operat­ing on a joint ferrous yoke.
  • the parallel placing of the two fields with permanent magnet energizes the work surface, while their connection in series causes de-energization.
  • said magnetic systems to function, must always be under voltage, so all the dies must be equipped with mains connections, with relevant safety and protection devices, and the rooms to be used for pressing workshops equipped with over­ducts and raceways built into the walls or floors, to contain the supply cables of each die.
  • a further problem is that, if there is even a temporary black-out, the upper movable plugs may come loose and fall, with the risk of considerable damage to the dies and, even more, to the operators.
  • the object of the present invention is to eliminate the abovementioned problems.
  • the invention solves the problem by means of devices connecting the plugs to the press dies used for the formation of tiles, with which the following results and advantages are obtained:
  • the devices are of the magnetic type in which the supply with line or battery voltage is only required at their energization or de-energization; the voltage supply system is preferably freed from the presses, it is only involved in said energi­zation and de-energization operators and can be used for an unlimited number of presses, separately; the magnetic force applied to the connecting devices is guaranteed sufficient to keep any type of plugs in perfect position for unlimited times; current supply expenses are cut to a negligible level; all systems are substantially safer; the upper plugs cannot fall, even without current, as the magnets of the devices be­come permanent, and remain so until they are de-energized.
  • a press for the formation of tiles (1) comprises an upper movable plate (2) with mobile plugs (3), and a fixed base (4), supporting the plug holder (5), the matrix or case (6), the sub-plugs (7) and the lower fixed plugs (8).
  • the press is equipped with magnets (9), which, fixed to said mobile plate (2) and said sub-plugs (7) stiffly engage the mobile plugs (3) and fixed plugs (8).
  • the magnets (9) are applied, in adjoining longitudinal or transversal parallel rows, or adjoining or reticulate oblique rows, on the entire surface (17) of the upper mobile plates (2) and on the entire surface (18) of the fixed sub-plugs (7), on which the mobile plugs (3) and fixed plugs (8) are fixed.
  • the operation of the abovementioned magnets (9) is based on the exploitation of the energy supplied by two fields with permanent magnets, operating on a joint ferrous yoke.
  • the placing in parallel of the two fields energizes the work surface, thus causing the fixing of the plugs (3) and (8) to the relevant upper mobile support (2) and lower fixed support (7), while de-energization is obtained putting these two fields in series, which short-circuit each other in turn in­side the joint ferrous yoke.
  • magnetictoconversion i.e. the switch from the phase in parallel to that in series, or viceversa
  • magneticconversion is given by the polar inversion or semi-hysteresis of one of the two permanent magnetic cores used through the action of an elec­tromagnetic field of high intensity, but of very short dura­tion, generated by the solenoid valve in which the reversable permanent magnetic core is immersed.
  • the joint ferrous yoke takes on the characteristics of permanent magnet (9), and remains in that state until de-energization is produced.
  • the magnets (9) Withhold and stiffly fix the plugs (3) and (8), maintaining them in this state even after termination of the supply of electric energy which has generated the energizing electromagnetic field.
  • magnets (9) are equipped with lead wires (10), ter­minating with sockets (11), applied, respectively, on the upper mobile plate (2) and the plug holder (5).
  • the command unit (12) is supplied either by the standard electric energy distribution system through a pin (14), or by one battery or more (15), preferably of rechargeable type.
  • Said unit (12) and any batteries (15) are preferably installed on a mobile support or trolley (16).
  • a single trolley (16) with a command unit (12), supplied by mains or batteries (15), can be used to energize or de-energize the magnets (9) corresponding to the upper supports (2) and lower supports (7) of any number of presses (1) placed in the same room or in different rooms.
  • the job of the command unit (12) is to supply the electric energy necessary to generate the abovementioned electromagnetic field in suitable directions and intensities to the magnets (9) which are connected to it by means of the pin (14), so­ckets (11) and leads (10).
  • the unit can be separated and used for other presses (1).
  • the command unit (12) is therefore used only to carry out the phases of energization and de-energization of the magnets (9), while, in other periods, it is separated from the presses (1), which can perform their processing cycles freed from the power supply systems.
  • the command unit (12) can therefore be used for an unlimited number of presses, separately, while the magnetic force applied to the energized magnets (9) is sufficient to guarantee a per­fect permanence in required position of the plugs (3) and (8) of any shape and size, for unlimited times and without conti­nuous consumption of electric energy.
  • any batteries of the command unit (12) can be maintained under voltage for recharging.
