Definitions

  • the object of the present invention is an improved machinery vibrating device that includes significant innovations and advantages compared to the presently existing devices with the same purpose.
  • the new invention refers to a device, particularly applicable to vibro-compressor machines for the manufacture of moulded parts in concrete or similar that includes a vibrator table operated by means that include a motor linked by at least two motorised toothed pulleys, by means of a drive axle that, through a belt, turns pulleys connected to two moving cylinders transferring the transmission axle movement of the motor to two drive pulleys.
  • the present invention according to claim 1 has been developed for the purpose of providing an improved vibrating device for machinery that solves the previously stated disadvantages, moreover, providing other advantages that will be clear from the description which is attached below.
  • the improved machinery vibrator of the present invention is especially applicable to vibro-compressor machines for the manufacture of moulded parts in concrete or similar, that includes a vibrator table activated by driving means that include a motor linked to at least two motorised toothed pulleys on a single one drive axle that, through a belt, turns pulleys connected to driving means, transmitting the movement of the transmission axle of the two eccentric masses, and is characterised in that the pulleys connected to the two cylinders are joined to some additional pulleys forming tandems that are displaceable in regard to an axis arranged in a nearby area or an imaginary union shaft between the centres of the pulleys that make up each tandem, said tandems being joined to each other by means of a connecting rod in such a way as to allow the relative movement between same so that the angle defined by the two axles of the opposing tandems present a variation such that the length of the complete travel of the belt around the pulleys remains constant and in which said tandems are connected to only one of the drive pull
  • a device is obtained with an improved working in comparison with those presently existing to align or to disalign eccentric masses, which in accordance with the relative position that they occupy, they are capable of bringing about vibration or not without the need of having to stop and resume the rotation of the pulley assembly likewise the motor that allows their turning movement.
  • the connecting rod allows a certain angle to be maintained (represented by means of the letter C in figure 2 ), it allows the belt to always maintain the same tension in all positions that can be taken up by the mechanism, this means, from its 100% performance working position to a position of rest.
  • the new device of the invention improves, on one hand, the angle included by the belt on the motorised and driven pulleys, so reducing the belt wear and, on the other hand, improves the greater mechanical precision in such a way that makes misalignment between the pulleys difficult, thus avoiding possible working irregularities.
  • the contact surface of the belt with the motorised toothed pulleys connected to the drive axle of the motor includes an angle of at least 175° that is considerably greater than that in the presently existing mechanisms.
  • the contact surface of the belt with the drive pulley takes in an angle of at least 200° in such a way that just the same as that stated in the previous paragraph, it is considerably greater than in the existing mechanisms.
  • the means of operation include operating cylinders that are slightly inclined in a convergent manner towards the toothed pulleys in respect of an imaginary horizontal axis.
  • the belt is in contact with the lower pulley of the tandem by the more outward zone whilst the upper pulley of the tandem the contact with the belt is carried out by the innermost part.
  • the vibrator device of the present invention includes operating means in order to carry out the vibratory movement of a table (11) (see Figure 3 ) that includes two motorised toothed pulleys (1), two drive pulleys (2), two tandems (3) each one of them made up of two pulleys (4) that can oscillate around some centres (5) that are connected to one of the drive pulleys (2), a connecting rod (6) that joins the two tandems (3) and pneumatic or hydraulic cylinders (7) that allows the movement of the tandems (3) to the required position.
  • the movement of the different pulleys is transmitted by means of a belt (8).
  • the mechanism or device object of the invention is shown in figure 3 in phantom lines, the rest of the mechanism represented being of a known type.
  • the contact surface of the belt (8) with the motorised toothed pulleys (1) linked to the transmission axle (9) of the motor (10) takes in an angle of at least 175° represented by the letter B in contrast to the device represented in figure 1 that is around 130°, whilst the contact surface of the belt (8) with the drive pulley (2) takes in an angle of at least 200° represented with the letter A in contrast to the device represented in figure 1 that is around 115°.
  • the belt (8) is in contact with the lower pulley (4) of the tandem (3) at the most outward area whilst the contact with the upper pulley (4) of the tandem (3) with the belt is made at the innermost part.
  • connection points of the connecting rod (6) with the tandems (3) likewise the length of said connecting rod (6) have values that are in line with the rest of the dimensions of the mechanism, such as the distance between the centres, the distance between the pulleys of each tandem, the distance between the centres of the motorised and drive pulleys, the distance between the centre of the motorised pulley and the line that links the points, in addition to the first diameter of each one of the pulleys around which the toothed belt runs and the total length of the belt.
