Definitions

  • the present invention relates to vibrating tables fitted to the presses used for the manufacture of concrete products, such as, for example, pavers, blocks, curbs, and others.
  • Conventional presses are generally equipped with a vibration device for the concrete itself, conventional and consisting of a single table driven in the vertical direction by unbalance vibrators, synchronized with one another and driven in rotation by motors, in particular electric motors.
  • the vertical unidirectional vibration force cannot be adjusted independently of the speed of rotation of the unbalances during the different phases of the vibratory cycle of the production of a product.
  • the intensity of the force, the amplitude of the displacement of the table and the accelerations transmitted to the mold and to the concrete which it contains are determined only by the only speed of rotation, possibly variable, always determined once for all and not susceptible of any other adaptation.
  • the machines used are almost always versatile, that is to say intended for the manufacture of a very wide variety of products for which it is often impossible to obtain favorable manufacturing conditions for various products, both at the level of quality than that of the optimal duration of the manufacturing cycle.
  • the present invention aims to achieve, by seeking to optimize as simply as possible the physical conditions of the pre-vibration, intended essentially for the proper filling of the molds, and of the vibration proper intended to ensure good compaction. of the material before final solidification.
  • the duration of pre-vibration and vibration is of the order of a third of the duration of the complete cycle.
  • the engines are started and eventually braking and stopping before restarting and restraining for the actual vibration.
  • the vibrating table 1 carrying a molding board 2 is usually carried by a frame 3 with the interposition of damping pads 4.
  • the table 1 is animated in vibration by four lines of shafts 5 to 8 superimposed in pairs and equipped with weights or unbalances 51, 61, 71, 81 fixed on these shafts.
  • the support bearings of these shafts are carried by two housings 9, 10 axially offset, comprising bearings lubricated by bubbling in an oil bath.
  • the housings 9, 10 are rigidly fixed under the bearing face of the table 1. Between the two housings 9, 10, the connection between each part of each shaft 5 to 8 is ensured by an elastic transmission with floating shaft 11 and designed to withstand the very severe stress conditions under acceleration and impact.
  • the shafts 5 to 8 are also connected, each end, to a drive device described below by an equally elastic transmission 12.
  • one acts on the vibration frequency by playing on the drive speed of the shafts 5 to 8 without the need for repetitive stops and restarts, and one acts on the vibratory force (acceleration) by playing on the relative positions unbalances 51, 61, 71, 81 without the need either to interrupt the rotation in each pre-vibration-vibration cycle.
  • each shaft 5 to 8 supported in a housing 13 receiving the necessary bearings is equipped with a toothed drive pulley 52, 62, 72, 82.
  • a toothed drive pulley 52, 62, 72, 82 At each of these pulleys drive, and supported by the housing 13, is associated in the same horizontal plane on the outside with the shaft lines 5 to 8, a crazy toothed pulley 53, 63, 73, 83 ( Figure 3).
  • a double notched belt 14 passes successively over and under each contiguous pulley, as in FIG. 3.
  • This belt 14 is intended for driving in rotation the pulleys 52, 62, 72, 82 carried by the lines of shafts 5, 6, 7, 8, the idler pulleys 53, 63, 73, 83 providing the belt 14 with an optimal winding arc on the drive pulleys 52, 62, 72, 82.
  • the path of the belt 14 relative to the pulleys 52, 62, 72, 82 and 53, 63, 73, 83 gives them a sense of opposite rotation at each level of the two stages of shafts 5, 6, 7, 8.
  • the resulting vibration imparted to the table 1 is therefore unidirectional and in the vertical direction.
  • the motors 15, 15 ′ are supported by a fixed frame 16, in the same way as the casing 13, completely independent of the frame 3 of the press.
  • the motors (or the motor and the gear) 15, 15 ′ are carried by a slide 17 movable axially relative to the casing 13 and to the fixed chassis 16 and controllable in displacement by a jack 18.
  • FIGS. 4A to 4D schematically illustrate this result where a maximum vibration in intensity is obtained in position A of the slide and minimum in position D, the positions C and B corresponding to intermediate values.
  • the motors 15, 15 ′ are assumed to be rotating when the unbalances produce their maximum effect downwards.
  • Figures 4B to 4D show in the upper part what happens when moving to positions B, C and D respectively by the effect of the tension induced on the toothed belt (assuming that the motor is at a standstill, which is never necessary).
  • the situation is illustrated at a given instant during walking, but when the passage into the corresponding position A, B, C or D has been carried out.
  • the solution proposed by the invention meets the current requirements of industrial production operations: reliability, precision and performance.
  • the synchronization of rotation of the unbalanced shafts, ensured by the toothed belt, makes it possible to avoid the usual pinion trains whose lubrication is not compatible with high speeds of rotation and a satisfactory longevity.
  • the bearing support casings contain only the necessary special bearings, the unbalances being fixed at the outside of these casings, on the ends of intermediate shafts.
  • the double notched belt is maintenance-free and has a long service life.
  • the loads it induces on the bearings are low and the maximum linear speed can be very high to produce a vibration frequency of up to 100 Hz. It also allows automatic movement of the motors without mechanical components other than the slide to cylinder, fast and precise movement allowing continuous adjustment of the vibration force between a maximum value and a zero value.
