APPARATUS FOR LAYING COATING F RESINOUS MATERIAL Tests have shown that it is not possible to properly lay linings comprising synthetic resins, generally used as a binding agent, with the aid of machines or of reduced scale machines currently used for the laying of bituminous or other coatings. As a matter of fact, these coatings or linings comprising synthetical resins in the form of a very pitchy mass prior to laying. Therefore, the existing laying machines become rapidly clogged and do not permit a satisfying laying. In particular, the vibrating element of the conventional laying machines becomes rapidly covered with a layer of these lining materials. In fact, the material to be laid was found to be more easily adhere to the vibrating element and the other mechanical parts of the laying machine than to the ground to be covered, and this evidently renders proper laying of the lining or the coating impossible.
The present invention intends to remedy these drawbacks and has for its object a device for the laying of bottom linings comprising synthetic resins which comprises a driven frame and a partition preventing the material to be laid from contacting the frame and permitting a progressive setting into place of this material.
The attached drawing shows schematically and by way of example one embodiment and some variants of the laying device according to the invention.
FIG. I is a side elevational view of the laying device;
FIG. 2 is a detail in cross section and on an enlarged scale.
FIG. 3 is a detail in elevation and on an enlarged scale as seen from A in FIG. 2;
FIG. 4 shows on an enlarged scale and partially in cross section a variant of a part of the device shown at Fig. 2;
FIG. 5 is a cross section on line lV-IV of FIG. 4;
FIG. 6 is an elevation on an enlarged scale seen from the rear of a variant of the laying device;
FIG. 7 is a cross section on lineVIl-Vll of FIG. 6.
The laying device for linings comprising synthetic resins comprises a frame having two parallel beams I, connected at their fore ends by crossmember 2 and at their rear ends by a structure 3. Each of these beams carries two pulleys 4, 5, revolving freely and provided with trapezoidal grooves. Laid in these grooves and tightened between each set of pulleys 4,5 is a trapezoidal belt 14 forming a driving track for the forward movements of the laying device.
It is to be noted, as it is particularly well shown at FIG. 5, that the trapezoidal belt projects out of the grooves of the pulleys 4, 5 in order to compact the ground.
The structure 3 carries a plate 6 on which are fixed on the one hand a driving motor 7 and on the other hand a gear reducer 8 which may be of the radicon' type for example. The motor 7 may be an electric motor or a combustion engine, according to the desired embodiments.
The outlet shaft 9 of motor 7 is provided with a chain pinion connected by means of a transmission chain 10 to a chain wheel carried by the entrance shaft 11 of the gear reducer 8. The outlet shaft 12 of the gear reducer 8 carries a chain pinion connected by means of a transmission chain 13 to a chain wheel 15 which is fast with the shaft of a pulley 4. An identical driving linkage connects the other pulley 4 to the mechanical reducer 8 so that the two trapezoidal belts 14 forming the tracks are driven in synchronism by the motor 7.
The use of trapezoidal belts as driving tracks is very advantageous since:
a. they are of a low cost and may thus be inexpensively replaced, they are easily taken off and can be rapidly cleaned, and they insure a good adherence with the ground without damaging it.
This bottom lining layer device comprises further a vibrating beam located at the rear of the device and shown on an enlarged scale in Figs; 2 and 3.
This vibrating beam is constituted by an angle iron 16 mounted on the free end of a leaf spring 17. The spring 17 is tightened between the upper surface of the angle iron 16 and the lower face of a ruler 18, the ruler I8 and the angle iron 16 being connected together by means of screws, for example. The other end of spring 17 is rigidly fixed on an angle piece 19 which is fastened on the structure 3 by means of a tightening device 20 in such a manner as to be height adjustable.
The lower surface of this vibrating beam is constituted by a rod 21 of synthetic material, for example Teflon (TM) or in Nylon, fixed on the wing of the angle iron.
The upper surface of the ruler 18 is covered over at least part of its length with synthetic material 22, such as Nylon or Teflon' (TM).
Via the leaf spring 17, the part consisting of the components l6, l8 and 21 is fixed to the frame of the device but may, with respect to the frame undergo displacements in a substantially vertical direction having an amplitude which may be up to several centimeters.
The laying device comprises further for actuating device for imparting to the vibrating beam its vertical displacements. In the example shown in Flg. I, this actuating device comprises a cam constituted by three rollers 23 fonned in the example shown by roller bearings each carried by one end of an arm 24. The arms 24 are disposed in a star-shaped relationship and fixed on a hub 25 joumaled on a horizontal axis 26.
The hub 25 carries a chain wheel connected by means of a transmission chain 27 to a chain pinion carried by the entrance shaft of the reducer 8. This cam (23, 24, 25) is thus driven in rotation by the motor 7 also.
An adjusting device makes it possible to modify the height of the axis 26 so that during the rotation of the cam its rollers 23 enter in contact with the upper surface of the ruler I8 covered with a synthetic material. This cam acting as an cecentric during its rotation causes vertical displacements of the vibrating beam against the action of the leaf spring. The synthetic material 22 serves to reduce the wear between the rollers 23 and the ruler 18.
The oscillatory frequency may be adjusted by means of the teeth ratios of the wheels and pinions of the chain transmission. This frequency may for example be comprised between I50 and 250 oscillations per minute.
The laying device comprises further a partition intended on the one hand to prevent any contact between the material M to be laid and the vibrating beam and, on the other hand, to shape progressively the material M.
This partition is constituted in the embodiment by a blade or plate of thin spring steel 28, one end or edge of which is rigidly fixed on the angled part 19 by any tightening means, and the other end or free edge of which is applied through its own elasticity against the ground.
This blade or plate 28 extends thus from the lower extremity of the angled part 19 to slightly beyond the vibrating beam. The material M to be laid located between the ground and the plate 28 tends to displace the latter resiliently upwardly (see Fig. l). The blade 28 therefore assumes a curved as shown on the drawing. Further, the material M to be laid applies this blade 28 against the rod of the vibrating beam so that its free end is subjected to the displacements of this vibrating beam. This blade 28 extends over the whole width of the vibrating beam, that is to say over nearly the entire width of the laying device.
The shape of the blade 28 is such that the material M to be laid located between the blade 28 when the latter is in service position and the ground will progressively stretch during the displacement of the device in direction of the arrow f, and be compressed to form the ground lining.
It is to be noted that the material to be laid does not enter in contact with the vibrating beam so that this beam cannot become clogged. Furthermore, the material to be laid, which is very sticky, enters in contact with smooth parts only, the lower face of the angled piece 19 and the spring blade 18, which are caused to be in continuous translatory motion with respect to this material. Therefore, the said material slides on these surfaces without adhering to them, which renders possible the correct laying of a coating comprising a synthetic material. The operation of the laying device is as follows:
The material M comprising the synthetic resin is placed in bulk between the beams 1. Then, the motor 7 is activated, which causes on the one hand the advancement of the device in direction of the a arrow f, and on the other hand, the continuous oscillation of the vibrating beam.
As the laying device advances in direction of the arrow f, the material M to be laid is pressed against the bottom by means of the lower part of the piece 19, stretched by contact with sliding blade 28 and compressed by the oscillations imparted to theblade 28 by the vibrating beam. The vibration of the blade 28 causes a progressive shaping as well as a progressing compression of the material M so that to the rear of the advancing laying device a floor lining is formed. Tests have shown that the material to be laid forms a hill before the angled part 19, which hill moves in the direction of the arrow f during the advancement of the device. In this manner, all the material M is continuously in movement with respect to the laying device and cannot adhere to any part of it.
The forward speed on the device is for example of the order of some meters per minute, and the laying capacity may be of some square meters'per minute. it is evident that the laying capacity of the device may vary within wide ranges depending on the dimensions and on the forward speed of the laying device.
FIGS. 4 and 5 show a modification of the vibrating beam of the laying device. In these figures, the vibrating beam is constituted by a plate 29 driven in reciprocal displacement by means of an eccentric 30 driven in rotation through a chain pinion 31 connected to the motor 7 and journaled on the structure 3.
The lower edge of this plate 29 is provided with a ruler 21 of synthetic material, the lower surface of which is used as an abutment for the spring blade or plate 28 of the partition.
The operation of this embodiment is in all ways similar to the one of the embodiment described above.
In the drawing the spring blade 28 is shown as being disposed at substantially a 30 angle with respect to the ground. This angle is of course adjustable and may be comprised between l0' and 50 for example. Further, this blade 28 is planar but deflected to curved configuration because it bears on the ground through its own elasticity, and the convex part of it is directed toward the ground. Even though this is a preferred embodiment, it'is evident that the blade 28 could also be made curved per se.
Numerous modifications are possible without departing from the scope of the invention. The main feature of the device resides, however, in the spring blade 28.
FIGS. 6 and 7 show an embodiment of the laying device in which the driving device for the vibrating beam is independent.
In this embodiment the actuating device of the vibrating beam is constituted by a vibrator having an eccentric 32 of a well-known type disposed longitudinally transversally of the laying device. This eccentric vibrator 32 comprises a shaft which is eccentcred and pivoted in bearings 33 fixed inside a protective tube 34. The latter is mounted by means of fixing parts 35 on a plate 36 which is itself mounted on the rear part of the angled piece 19 through the intermediary of so called 7 blade 28 fastened on the angled piece 19 abuts against the ruler 28 under the effect of the material M.
In this embodiment, the shaft is provided with a pulley 39 intended to be connected by means of a trapezoidal belt 40 to one of the stages of a multiple stage pulley 41 fastened on the shaft of a motor 42 which latter fixed on the vertical part of the angled piece 19, or on another part of the frame of the laying device. This motor 42 may be an electric one or a combustion engine according to the embodiments.
The advantage of this embodiment resides in the fact that on the one hand, it provides for actuation of the vibrator independently of the drive for the laying device and, on the other hand, it permits read variation of the oscillatory frequency of the vlbratlng beam ecause of the presence 0 the multiple stage pulley 41.
Tests have shown, in fact that it is possible to obtain a correct laying of the material M even without the beam being vibrated. The material is compressed and stretched by the shape of the spring blade 28. it suffices that the rear edge of the blade 28 bears against an abutment replacing the ruler 21 or even that the blade be sufficiently rigid to sufficiently stretch the material M.
