Definitions

  • a device for grouping and bundling rod-like members having a conveyor comprised by at least a pair of adjacent endless chains rotatably driven and connected by an adjustment device for permitting relative movement to occur between said chains as desired so as to vary the phase relationship therebetween.
  • Each of said chains has bundling members secured thereto which cooperate to define a substantially V-shaped grouping and bundling space for receiving the rod-like members.
  • the bundling space is defined by a front wall member secured to one of the chains and a rear wall member secured to the other chain, where by relative movement between the chains permits adjustment of the spacing between the wall members to vary the size and configuration of the bundling space.
  • This invention relates to an installation for binding oblong fagots comprising binding means provided with at least one binding head adapted to place, tighten and knot ties around an oblong fagot placed in the binding position and conveyor means for receiving said oblong fagot and bringing it first into the binding position, then into the discharge position.
  • Installations of this type have already been employed, especially for the purpose of forming bundles from a predetermined number of bars or other structural sections, or alternatively for the purpose of forming fagots from a predetermined number of bundles.
  • the conveyor means which are employed in such plants fail to ensure that the bars or bundles which are presented to the binding heads in the form of fagots correspond with a sufiicient degree of approximation to a circular cross-sectional configuration. Consequently, after being tightened together and bound, the bars or bundles tend to settle and the tie no longer holds them together with the requisite firmness.
  • a further well-known disadvantage of installations of this type lies in the fact that they do not always operate with optimum efliciency. In fact, it frequently occurs that an installation which is designed to tie bundles for the purpose of constituting fagots follows an installation which ties structural sections for the purpose of forming bundles. It is manifestly apparent that, under these conditions, the rate of production of the second installation is a submultiple of the production rate of the first; if the number of ties is the same and if the fagot is made up of n bunles, the second installation places n times less ties than the first and therefore has a highly unsatisfactory performance from an economic standpoint.
  • the present invention is intended to circumvent the disadvantages referred to and, with this object in mind, is directed to a binding installation which is essentially characterized in that the conveyor means are cradles which are carried by endless chains constituting the base of said cradles and that the upstream and downstream side-plates of said cradles are coupled to two adjacent chains having adjustable relative longitudinal positions.
  • the cross-sectional configuration of a cradle can be adapted either to the number of bars or to the number of bundles which it is intended to accommodate by adjusting the relative longitudinal positions of the adjacent chains in such a manner as to ensure that the shapes assumed by the fagots will be as close as possible to their final shape when tied.
  • all the chains fitted with upstream cradle-plates are coupled for rotation with each other so as to form a group of thrust chains and all the chains fitted with downstream cradleplates are coupled for rotation so as to form a group of traction chains, the relative longitudinal positions of the two groups being adjustable.
  • This arrangement makes it possible to adjust the shape of the cradles in a single operation for the entire binding installation.
  • the driven sprockets of the chains are carried both by the countershafts and by at least one drive shaft on which the driven sprockets of one group are keyed and on which the driven sprockets of the other group are mounted to rotate freely as well as by an adjustment shaft on which the arrangement is the reverse and which can be driven either at low speed for adjustment purposes or in synchronism with the drive shaft for normal operation.
  • the drive shaft is provided with a brake which is applied during the adjustment operation performed by the adjustment shaft.
  • the cradles thus formed have the shape of a semihexagon. A shape which is fairly close to that of a hexagon is thus imparted to the pile of fagots received by said cradles and formed between the two cradle-plates.
  • the number of binding heads must in certain cases be smaller than the number of ties to be knotted around a same fagot, and the binding means are accordingly adapted to move transversely for the purpose of executing a number of binding operations beneath the carrying run of the conveyor-means within a space which is left free by the return runs.
  • the conveyor means can in such cases be provided with four countershafts or drive shafts so arranged as to define a space of substantially rectangular cross-sectional configuration inside which a binding machine is mounted on rails.
  • FIG. 1 is a sectional view of the installation
  • FIG. 2 is a diagrammatic view showing the arrangement of the shafts.
  • FIGS. 3 and 4 are respectively a side view and an overhead plan view on a large scale showing the manner in which a cradle-plate is mounted on one of the chains of the installation.
  • an installation according to the invention can be mounted in a pit 1 which is designed to accommodate alternately bases 2 in the form of an inverted U and flat bases 3 which rest on the bottom of the pit.
  • Each inverted-U base is in turn adapted to accommodate an upstream bearing unit 4 and a downstream bearing unit 5 on which are supported respectively a top upstream countershaft 6 and a downstream drive shaft 7.
  • Each fiat base 3 is in turn adapted to accommodate a bottom downstream bearing unit 8 on which is supported an adjustment shaft 9 and, at the upstream end, a casing 10 in which is mounted a jack 11, said jack being in turn H adapted to actuate an arm 12 which is pivotally mounted at 13.
  • the series of arms 13 carries the bottom upstream countershaft 14 which thus operates as a tension regulator.
  • the four shafts 6, 7, 9 and 14 carry a certain number of sprockets 15, 16, 17, 18, 19 and 20 which are placed at the level of the intervals between two bases 2, there being passed over said sprockets continuous chains 21 and 22 which therefore have an active top run 23, or carrying run, and return runs 24, 24 and 25.
  • Rails 27 have been laid across the entire width of the transverse space referred to above and therefore span the gaps between the bases 2, a binding machine 28 of known type being adapted to run on said rails.
  • a machine of this type is composed, for example, of a stationary frame 29 and a frame 30 which are interconnected by a number of arms 31, said arms being pivotally attached at 32 to the stationary frame and elbowed in order to be subjected to the action of a jack 33 which accordingly permits the possibility of adjusting the height of the frame 30 between a position in which it is shown in full lines to a position shown in chain-dotted lines.
  • the top face of the frame 30 is provided with two binding jaws 34 which are shown in the work position and in chain-dotted lines in the open position.
  • the arms 34 are adapted to clamp together a bundle assembly of structural shapes or sections, then to place and knot a length of binding twine around said bundle assembly.
  • an upstream conveyor 35 which is capable of bringing one by one or in groups a predetermined number of bundles 36 so as to form at the upstream end the bundle assembly 37 which will be tied at 38, then discharged at 39 in the form of fagots by any conventional means which have not been illustrated.
  • FIGS. 3 and 4 show the manner in which there is formed a chain of the type designated by the reference 21 or 22, the links of which are fitted in the usual manner with roller link plates 40 which are fitted over roller pins 41 and spaced by means of bushings 42.
  • roller pins 41 are fitted at 43 with bar-link extensions 44 which are pivotally connected in pairs by means of a common pivot-pin 45.
  • FIG. 3 shows that the bar-links 44 have approximately the same length as the interval between two roller pins 43 on which they are carried, the resultant configuration being approximately that of an equilateral triangle when looking on the side.
  • the plates 46 or 47 which join two parallel bar-links 44 are therefore inclined at an angle of approximately 60 with respect to the horizontal plane determined by the chains 21 or 22.
  • the intended function of the plates 46 and 47 is to form either the downstream side 46 or the upstream side 47 of the successive cradles which are shown diagrammatically in FIG. 1 and the bottom of which is constituted by the chains themselves.
  • the chains 21 work in conjunction with sprocket-wheels 16 which are keyed to the shaft 7 and with sprocket-wheels 18 which are mounted to rotate freely on the shaft 9.
  • Each sprocketwheel is adjacent to a chain 22 which, on the contrary, works in conjunction with a sprocket 17 which is mounted to rotate freely on the shaft 7 and with a sprocket 19 which is keyed to the shaft 9.
  • the group 21 on the one hand and the group 22 on the other hand are intended to be driven by the shaft 7 and receive the upstream cradle-plates 47.
  • the second group 22 or so-called traction chains are intended to be driven by the shaft 9, and receive the downstream cradleplates such as the plate 46.
  • FIG. 1 there can be seen a chain 21 with the upstream cradle-plates 47 concealing a chain 22 with the downstream plates 46 of the corresponding cradles.
  • the shaft 7 is equipped with a driving motor M and a brake F Whilst the shaft 9 is equipped with a driving motor M a dogclutch C and a regulating motor R.
  • all of the chains 21 and 22 are in turn driven in synchronism and the controlled operation of the motors permits the step-by-step displacement of said chains so that the cradles are moved successively from position 37 to position 38, then to position 39.
  • the cradles receive bundles 36 which form an assembly or pile having a cross-sectional configuration which is generally similar to that of a regular hexagon.
  • the bundle assembly thus formed is tied. Then, in position 39, the completed fagot can be discharged by any known means.
  • the binding machine is placed in the binding or tying position in readiness for the first tie.
  • the machine By means of the jack 33, the machine is set in the position shown in full lines in which it is in readiness to execute the binding operation.
  • the jack 33 is then once again actuated so as to produce the downward motion of the frame 30 while the jaws 34 remain open, thereby permitting the displacement of the complete unit along the rails 27 so as to reach a second binding position.
  • the jack 33 is again put into operation so as to raise the frame 30, a second tie is placed in position and so forth until a given fagot has received all its ties.
  • the bundles may take up at 37 a volume which is either too large or too small and therefore do not correspond with sufiicient approximation to a circular cross-sectional configuration to permit them to be correctly assembled at 38.
  • the dog-clutch C When the installation is at rest, the dog-clutch C is disengaged and the brake F is applied.
  • the motor R is started up and accordingly initiates the displacement of the group of chains 22 with respect to the group of chains 21, that is to say a displacement of the downstream cradle-plates with respect to the upstream cradle-plates. This operation makes it possible to adjust the width of the cradles, whereupon the brake F is released and the dog-clutch C is engaged.
