Definitions

  • the tamping machine has a frame including rollers and vibrating means, and the frame includes two longitudinal beams interconnected by cross beams secured at their ends to the longitudinal beams.
  • a respective bar of plastic composition material is interchangeably secured to each longitudinal frame beam and each bar has two vertically spaced rows of longitudinally spaced apertures serving as bearings for the rollers.
  • the rollers are mounted in the lower row of apertures and, if a bar is damaged, it may be inverted so that the rollers can be rotatably mounted in the former upper row of apertures.
  • the vibrating means comprises at least two parallel connected magnetic vibrators secured at central portions of the cross beams, and noise-reducing insulating material is associated with each vibrator.
  • the cross beams are preferably inverted channels whose legs or flanges are secured to the longitudinal beams, and the longitudinal beams are preferably angles.
  • the channels of the cross beams are preferably filled with a sound-absorbing material such as plastic foam.
  • an eccentric'motor may be mounted on an intermediate cross beam with its axis extending; parallel to the axes of the rotor, and one or more weights, which may be either units or multi-part weights, may be supported on the frame.
  • SHEET '4 (IF 4 1 TAMPING MACHINE FOR SETTING FLOOR COVERING TILES FIELD OF THE INVENTION
  • This invention relates to tamping machines for setting floor covering tiles and, more particularly, to a novel and improved tamping machine in which the supporting rollers are rotatably mounted in plastic composition bars interchangeably secured to longitudinal beams of the machine frame.
  • the rollers are mounted directly in the longitudinal beams of the frame, which also mount the vibrating means of the machine, such as magnetic blow or impact vibrators.
  • the vibrating means of the machine such as magnetic blow or impact vibrators.
  • Such a design has the result that the blows or impacts of the vibrators, which act directly on the supports of the rollers, not only cause considerable noise but are transmitted directly, through the rollers arranged in the range of the impact zones of the supportspto the tiles to be set.
  • This localized impact of the vibrations on the tiles can lead, in the case of brittle tile material, to cracking or destruction of individual tiles. Additionally, it requires a high degree of strength of the frame connec tions and of the bearings of the rollers.
  • the tamping machine embodying the invention avoids these disadvantages in that the ends of cross beams of the lower frame interconnect two longitudinal frame beams with each other, and each longitudinal frame beam has interchangeably or exchangeably secured thereto, as by screws, a respective plastic composition bar, with the rollers being rotatably mounted in these bars. Since the impacts of the vibrators do not act directly on the longitudinal beams, the blow or impact energy is distributed evenly over the rollers.
  • the plastic bars, serving as bearings for the rollers not onlyhave a noise-reducing and impact-reducing effect, but also prevent possible deflection of the roller bearings causing damage to the longitudinal beams and thus tothe frame. By exchanging the plastic bars, any damaged bearings can be easily replaced.
  • the vibrating means has at least two parallel-connected magnetic vibrators whose working chambers are arranged in closed housings which are secured on the center parts of the cross beamsnlthas been found to be advantageous to provide two cross beams'each carrying at least two vibrators, and to design the cross beams as inverted channels whose bases are connected to the housings of the vibrator blow or impact chambers.
  • These cross beams have the edges of their downturned flanges secured to the horizontal arms of the longitudinal beams, which preferably have an angle cross-section.
  • the downwardly extending legs or arms of the longitudinal beams carry, on the surfaces facing each other, the plastic composition bars formed with bearing openings for the rollers.
  • the interior of the cross beams which is open at the bottom, preferably is filled with a noise-reducing material, for example, with plastic foam.
  • the housing jacket enclosing the vibrator impact chambers preferably is provided with a cuff of noise-reducing insulating material.
  • the machine is substantially improved, in this respect, by securing, at least substantially in the center of the roller frame, an eccentric motor with the axis of rotation of the eccentric body extending parallel to the rollers.
  • the eccentric motor can form the vibrating means alone, or can act in cooperation with magnetic vibrators as mentioned above and, in the latter case, it can be started and stopped independently of the magnetic vibrators.
  • the eccentric motor which preferably works at a relatively high speed of 2,800 rpm, for example, also produces a sort of vibration which, if magnetic vibrators are also provided, is superposed on the vertical vibration effected by the magnetic vibrators, but which does not act strictly vertically, due to the revolving eccentric body, but rather uniformly in a vertical plane through the roller axis.
  • the bearing pins of the rollers preferably are mounted with relatively great radial play in the plastic bars. This also avoids a slightly projecting cover plate from being dis placed by a striking roller.
  • An object of the invention is to provide an improved tamping machine for setting floor covering tiles.
  • Another object of the invention is to provide such a machine which isfree of the disadvantages of known prior art tamping machines.
  • a further object of the invention is to provide such a machine in which the impacts of magnetic vibrators do not act directly on the longitudinal beams of a frame and in which the impact energy is distributed evenly over the supporting rollers.

  • Bars 12 are formed with two vertically spaced rows of bores 13 and, in the bores 13 of the bottom row, there are mounted end pins 14 of rollers 15.
  • the rows of bores 13 are arranged so that, when wear damage appears in the bores 13 of bars 12 receiving roller pins 14, these bars can be removed and used again as bearing bars by turning them through I80".
  • bars 12 are placed on end pins 14 of the rollers to form a unit including rollers and bars, and this unit is inserted as a whole into the frame and secured therein by screws engaged through bars 12 and into longitudinal beams 1.
  • two magnetic vibrators 3 are arranged on the center of each cross beam 2 between longitudinal beams l, and the impact chambers of vibrators 3 are formed in cylindrical housings 4 which are enclosed or embraced by a cuff 5 of noisereducing material, as best seen in FIG. 4.
  • An impact-damping plastic disc is inserted into the impact chamber of each housing 4, and housings 4 are welded on cross beams 2.
  • the cross beams 2 are drilled at the respective points 7 and welded again with the housing bases, as shown in FIG. 4.
  • the parallel-connected vibrators 3 are connected by cables with a junction box 8 arranged on one cross beam 2, and to which there can be connected a current supply cable, which has not been shown, leading to a switching apparatus including a pulse transmitter.
  • the switching apparatus preferably is arranged on a guide yoke 9 by means of which the machine can be guided by hand over the tiles to be set, and whose arms are pivotally mounted on flanges or ears 10 secured on longitudinal beams l.
  • the downwardly opening interiors of cross beams 2 are filled with sound-absorbing material 11, such as plastic foam, for example.
  • the vibrator impacts are transmitted to all rollers in a manner distributed evenly over the entire length of longitudinal beams 1. This, and the sound reduction attained by discs 6 and bars 12, not only protects the machine parts but also prevents damage to the tiles to be set. While the described embodiment mentions four parallel-connected vibrators 3, it is possible to provide only three, or more than four, vibrators. Thus, for example, one or two additional vibrators could be arranged fixedly or disengageably on the cross beams 2, or on one or two additional, and possibly disengageable, cross beams in order to be able to adapt the operation of the vibrating machine to the respective conditions.
  • FIGS. 5 and 6 the same reference numbers have been used for the same parts, as were used in FIGS. 1 and 2.
  • the crossbeams 2 carrying the magetic vibrators are connected with each other by a center bridge 20 on which is secured, at the center of the frame, an eccentric motor 30.
  • the axis of rotation a of the eccentric which has not been specifically indicated, extends parallel to the axes of rollers 15. Since the machine is rolled backward and forwardly during use, by means of guide yoke 9, the direction of rotation of eccentric motor 30 is immaterial.
  • Bores 33 of plastic bars 12, serving as bearings for the end pins 14 of rollers 15, have a larger diameter than pins 14 so that rollers 15 are mounted with a relatively large radial play in bars 12.
  • the rollers thus can adapt themselves better to unevenness of the floor. The striking of a roller against the floor elevation thus is facilitated, and the practically continuous contact of all rollers with the floor is ensured to a great extent.
  • eccentric motor 30 superposes, on the vertical impacts of the magnetic vibrators, a rotating vibration, which leads to a particularly quiet and smooth running of the machine and to particularly good and rapid setting. If desired, it is possible also to work temporarily alone with the magnetic vibrators, or alone with the eccentric motor, or to omit the magnetic vibrators entirely for smaller machines.
  • the vibrating means comprises only the eccentric motor 30.
  • removable weights 35, 35a, or 35b are arranged laterally of eccentric motor 30 on cross beams 2.
  • each weight can consist of a single piece and be provided with a handle for easier handling.
  • the left side of FIG. 7 shows a variation in which the weight is a two-part weight comprising the components 35a and 35b.
  • Weights 35 are arranged only loosely on cross beams 2, so that they can thus move freely in a vertical direction, while they are secured against lateral displacement by pin connections as shown, for example, in FIG. 7 on the left side. If two-part or multi-part weights 35 are provided, the weight load can be adapted to the respective requirements. With the vibration machine running, the weights will begin to jump so that vertical impacts are produced through frame 1,2 and the rollers 15, which are superposed on the vibrations provided by motor 30. The combined vibrations effect a compression of the binding material for the covering tiles, the impacts on the main axis being produced by the jumping weights and acting directly on the tiles still projecting above the desired plane of the covering.
