Definitions

  • ABSTRACT A machine for binding together a number of bars, 1 Forelgn Appllcailoll Prwrlty Data tubes or the like elongated objects by means of an ad- Feb. 3, 1972 Netherlands 7201437 hesive tape including means for holding the objects in parallel relationship, clamping means for clamping the [52] U5.
  • the objects are usually supported fixed to the frame and the machine is provided with a mechanism with the aid of which the tape reel is rotated several times around the bundle of objects, after the free tape end has been fixed to a point on the periphery of the bundle of objects.
  • the supply of the objects takes place in longitudinal direction of the objects, which may be onerous in case of larger length sizes, appears to lead to low dependability whereas the relatively high costs of con struction are not too attractive.
  • the present invention aims at providing a machine of the type as described in the preamble, in which has been tried to eliminate the objections of the known embodiment, as well as to increase the productivity.
  • one or more transverse supports for the objects are present, said supports being mutually spaced in the longitudinal direction of the machine, and clamping means have been arranged adjacent at least one of said transverse supports, said clamping means being active from aside on the supported objects, by which clamping means the objects may be combined into a compact bundle, said clamping means, together with the objects to be clamped, being rotatably supported to the frame about the longitudinal axis of the bundle to be formed, whereas adjacent at least one of the clamping stations for the objects to be clamped, a member supported on the frame and carrying along the free tape end being movable to the periphery of the bundle to be formed and away therefrom.
  • the tape Since the bundle of objects rotates about the longitudinal axis thereof, the tape, after its free end has been brought into contact with the periphery of the bundle, is simply unwound from the spatially fixed arranged reel, which stimulates a quick course of the binding of the bundle.
  • the transverse support constitutes the bottom of a recess in a disc-shaped means, said recess extending from the periphery of said means to beyond said axis of rotation, said disc-shaped means being rotatably supported in the vertical plane by means of a number of support rolls arranged along the periphery of said means, each of said support rolls being rotatable about a fixed shaft connected to the frame, in which the said clamping means are movably positioned adjacent the recess of the disc-shaped means.
  • the recess of the discshaped means permits in a simple way supplying of the objects to be bundled transverse to the longitudinal axis of the machine.
  • the clamping means are constituted by two levers provided with a claw, which levers each being swingable in a manner about an axis directed transversely to a side face of the discshaped means and arranged reversed symmetric with respect to a centre line of the disc-shaped means passing through the said recess, such that the objects to be arranged in the recess, are clampable to a compact bundle between a surface at the recess bottom and an engaging surface at each of the said claws, the longitudinal axis of said bundle being concentric with the axis of rotation of the disc-shaped means.
  • the member carrying the free tape end is constituted by a guide and pressure roll, which is rotatably arranged at the angle portion of a cantilever, at which free lever end also the reel for the tape is supported and which cantilever is swingable to the frame adjacent its other lever end in a plane transverse to the longitudinal axis of the machine such that the tape end is adapted to be pressed via said guide and pressure roll against the periphery of the bundle to be formed.
  • a lever is rotatably supported, a cutting blade, having the shape of an isosceles triangle with an acute apex angle, of which angle the legs constitute the knife edges and of which the base is parallel to the axis of rotation, being secured transversely to the free end of which of the levers extending beyond the periphery of said roll. Since in the previously described embodiment and arrangement of the knife blade, the tape part leading from the reel to the windings around the bundle will almost be hit in the centre line on movement of the cantilever, the separation of the tape can take place in a faultless way.
  • the apex angle of the knife blade lies advantageously between 60 and
  • the free end of the cantilever, the claw-levers and the knife levers is pivotally connected to a piston-cylinder mechanism, the supply conduits, in particular those which lead to the mechanisms of the claw-levers, consisting of flexible material and being shaped according to a helical line having a large number of convolutions.

  • a pistoncylinder mechanism 8 has been arranged, by means of which mechanism a bar 9, connected to the piston of said mechanism, can be brought transverse to the strip 7 and inclining upwardly in the path of movement of the continuously supplied tubes 3, which can be caught by the bars 9 in case the binding machine is in operating condition.
  • an electronic pulse counter coupled to the above mentioned sawing mechanism, can be used, by means of which pulse counter the tubes 3, admitted to the guide strips 7, can be counted, and, as soon as the required number oftubes have passed the time necessary for bundling a preceding group oftubes in the machine and then discharging same from the machine, will be amply sufficient a signal for withdrawing of the bars 9, which, after passing of the blocked group of tubes will return by spring action into their blocking position, can be passed to the mechanism 8 as well as a signal for actuating of the binding machine.
