Definitions

  • the subject of the invention is a device for guiding a relatively rigid pushed wire along a path of length which can be modified as required, closing in on itself as a whole.
  • the ligature is made up by a head (which is not part of the present invention) which cuts the wire to the necessary length, puts it in tension and coils together in twist the two extreme parts.
  • the thread comes from a spool of thread from which it is unwound, pushed in a first channel through the tying head and guided around the articles to be tied together; then it borrows a second channel from the binding head to cross it again. After which, it is cut, stretched and twisted, as we said.
  • the object of the invention is a device which guides the thread around the articles to be tied between its exit from the tying head and its return therein.
  • the path that the thread has to travel closes substantially on itself; it follows an outline which reproduces the outline of the cross section of the articles to be linked.
  • This outline can be circular; it is most often oblong with straight parts connected by semi-circular parts.
  • Binding is often used to join together the different turns of the metal wire crowns, the size or importance of which is modified by a change in the length and the difference between the inside diameter and the outside diameter of the crown. This leads to modifying to a fairly large extent the length of the straight parts of the oblong path which must be followed by the tying thread which closes on itself by making a loop whose two strands are not in the same plane.
  • the main object of the invention is to provide a device for guiding a tying wire capable of giving it the desired configuration around articles to be tied, to the length just necessary, eliminating the obligation to swallow up an excess length. any.
  • a guide device is similar to a plate divided into a first part and a second part applied against each other, on either side of a median joint plane parallel to the faces main opposites of this plate.
  • a guide channel which, for example, starts from an inlet channel open to the outside and leads to an outlet channel also open to the outside.
  • a central opening is provided in the device, internally on the layout of the guide channel, to receive the articles to be bound.
  • the two parts are movable and can be spaced from each other relative to the joint plane to allow the wire loop to exit the guide device.
  • the device can be opened to receive the articles to be tied thanks to the fact that the two parts each have a general U-shaped profile with two spaced parallel branches; on the two parts joined together, the branches of one and the other are directed towards each other from opposite respective junction zones.
  • the two parts are movable by sliding one against the other of their internal faces, on either side of the joint plane, in the direction of the branches.
  • the central opening has two opposite curved extreme sides which are each located respectively on one and on the other part at the junction of the branches of these parts and two straight sides each formed by the joined branches of one and the 'other party.
  • the relative arrangement of the two parts against each other is possible between a first extreme position in which the central opening is formed by the two semicircles complementing each other and a second extreme position in which the central opening is constituted by one and the other semicircle spaced and each extended by the branches, which gives an oblong central opening, very elongated, with two opposite rectilinear sides joined at their ends by two semicircles.
  • the guide channel is hollowed out alternately in one then in the other of the internal faces of the two parts.
  • the guide channel is, for example, itself in a semicircle; it can be in the junction of the branches of the part where it is located and it can be opened towards the inside of the central opening.
  • the guide channel is spaced from the central opening and hollowed out in a branch of one part on one side and in a branch of the other part on the opposite side.
  • Ramps can be provided at the downstream ends, in the direction of passage of the tying wire, on each of the semicircular sides of the guide channel to connect each semicircular side to the straight side which follows it and which is hollowed out in the branch of the opposite side.
  • Figures 1 and 2 show a ring of son 1 shown in phantom, of cylindrical annular shape, which must be linked in several planes; it is placed in a binding machine represented only by its binding head 2 through which a binding wire is pushed, in the direction indicated by an arrow F, which must wrap a section of the crown 1.
  • a guide device 3 surrounds this section of the crown to guide the wire in a guide channel 4 and bring it back into the binding head 2 as indicated by an arrow F 2 .
  • the guide device 3 is analogous to a plate; it is composed of a first part 3A and a second part 3B which separate on either side of a joint plane parallel to the opposite main external faces of the plate.
  • FIG. 2 shows that when the tying wire surrounds an article to be tying, the opening of the device by relative spacing of the two parts 3A, 3B, allows this wire to be released so that the binding head 2 ties it.
  • Figures 1 and 2 are schematic; they show a tying head 2 which is separate and located outside the guide device 3. It is preferable in practice to integrate the tying head 2 with the guide device 3 as shown in FIG. 3, so that the inner channels of this head 2 become a fraction of the guide channel 4, which shortens the length of the binding wire put in place before the execution of the ligation.
  • the tying head 2 Although integrated inside the guide device 3, the tying head 2 remains independent since it must rotate on itself to twist the two free ends of the tying wire together. Before performing this twist, the tying wire makes a loop whose two ends cross, preferably being spaced apart by a distance equal to the diameter of this wire.
  • a detailed description of such a binding head can be found in French patent FR-A-2502582. In Figures 5, 6 the tying head has been omitted, for the simplification of the drawing.
  • the two parts 3A, 3B each have the profile of a U with two spaced branches respectively 6A 1 , 6A 2 for the first part 3A and 6B 1 , 6B 2 for the second part 3B. These branches are turned towards each other, from their junction zones, 7 and 8 respectively.
  • This central opening 9 has two opposite opposite curved sides 10,11, which are located one on the part 3A (side 10), the other on the part 3B (side 11) in the junction zones 7 and 8.
  • This central opening 9 also has two opposite rectilinear sides 12, 13 which are each constituted by a branch of the first part and by a branch of the second part (the branches 6A, and 6B, for the side 12 and the branches 6A 2 and 6B 2 for side 13).
  • the guide channel 4 is alternately hollowed out in one then in the other of the internal faces 5A, 5B of the two parts 3A, 3B.
  • the guide channel 4 can be dug in those of the two parts 3A, 3B which constitutes an extreme side 10, 11 of the central opening 9.
  • the first part 3A there is a first section in a quarter circle 4A (FIGS. 3 and 5) which is open towards the inside of the central hole 9 on the curved side 10.
  • the first section 4A departs from the straight edge 12. It is advantageously in a quarter of a circle tangent to the curved edge 10, which has a greater radius of curvature. It is interrupted as soon as it has started in branch 6A 1 , in the direction F 1 of the path of the tying thread pushed into channel 4.
  • a ramp 14 which rises to the level of the internal face 5A.
  • This ramp 14 provides the connection with a second straight section 4B hollowed out in the internal face 5B of the branch 6B, which can slide on the face 5A of the branch 6A 1 .
  • the second section 4B is continued by a third section 4C, in a semicircle, which is tangent to the curved end edge 11 and which opens towards the inside of the central opening 9.
  • the third section 4C departs from the edge straight 13 and ends with a ramp 15 which rises to the level of the internal face 5B.
  • This ramp 15 provides the connection with a fourth section 4D hollowed out in the face 5A of the straight branch 6A 2 of the first part 4A.
  • the fourth section 4D is followed by a fifth section 4E in a quarter circle, which is tangent to the extreme edge 10 and which is open towards the inside of the central opening 9.
  • the first section 4A communicates with a rectilinear inlet channel 16 in the direction F1 of arrival of the binding wire; the fifth section 4E ends in a rectilinear outlet channel 17 in the direction F2 of the binding wire outlet.
  • These rectilinear channels 16, 17 are in correspondence with the channels of the binding head 2 or, preferably, as explained above, are part of this head.
  • the binding wire is always well guided in the direction from F 1 to F z in all successive sections 4A to 4D of the guide channel 4.
  • These curved end edges 10, 11 of the central opening 9 can be brought into contact with the articles to be bound, as shown in the figure 6; in other words, the tying wire itself is brought into contact in the junction zones 7, 8 with the articles to be tied, whatever the size given to the central opening 9.
  • the tying wire n has practically no excess length in relation to the perimeter of the articles to be tied.
  • the second part 3B in the junction zone 8, in the interval between the branches 6A,, 6A 2 of the first part 3A, the second part 3B is provided with an extra thickness 18 which serves to limit outwards the section 4D of the channel 4.
  • the channel 4 In the straight sections 4B, 4C, the channel 4 is limited by the corresponding opposite internal face of the branches of the opposite part.
  • the two sections 4A and 4E in a quarter circle are not in the same plane; they are offset perpendicular to the plane of Figure 5 so that the inlet channels 16 and outlet 17 are spaced apart by a distance equal to the diameter of the binding wire.
