    • A44B19/62—Assembling sliders in position on stringer tapes

Definitions

  • the present invention relates to a machine for the automatic installation of sliders on closure strips with coupling profiles, this machine comprising means for feeding the sliders one after the other and in a determined position, guide means a pair of cooperating closing strips along an essentially rectilinear path, and means for opening the sliders and introducing them onto the strips.
  • the invention relates more particularly to said means which are provided for opening the sliders and introducing them onto the closure strips.
  • the purpose of the present invention is to remedy these drawbacks and to create a new, simpler, weaker machine, allowing laying rates much higher than current rates, which will give welders their full performance, and thus increase production.
  • a slider laying machine of the type mentioned at the beginning is, in accordance with the invention, characterized in that said means for opening the sliders and introducing them onto the strips essentially comprise, on the one hand, a rotor coupled to motor means making it possible to drive it in step-by-step rotation, this rotor being provided at its periphery with housings opening in the radial direction and capable of each receiving, in turn, a cursor at a location for the arrival of the cursors successive, and on the other hand a stator, extending along a part of the periphery of said rotor, essentially between said location of arrival of the sliders and said path of the closing closing bands, said rotor housings having, towards the terminal end of the stator, a path practically tangent to said path, said stator being further off-center with respect to the rotor, and shaped so that it has internally, that is to say facing the rotor, a surface e of support for the ends of the insertion face of the sliders
  • said ramp system can advantageously, and simply be constituted by a conformation in " V "from the bottom of the rotor housings, along which the edges of said cheeks can thus slide when the cursor is gradually pressed towards the bottom of its housing by the action of said stator bearing surface, which causes the opening of said cursor while the latter is moving towards the bands.
  • said sliders are of a type comprising opposite their bottom, namely on the ends of their introduction face, one or two pairs of ears, and that, in such a case, to obtain the same effect as above, said system of ramps comprises, in said bearing surface of the stator, grooves or the like, receiving said ears and progressively moving them apart, to open the cursor while it moves to the bands.
  • FIGS. 1 to 4 The known machine has been shown in FIGS. 1 to 4, as adapted to engage on a pair of closure strips 1, with coupling profiles 2, known sliders of the type comprising on their bottom 3 outer cheeks 4.
  • the introduction face of the cursors has been referenced in 5; it is indeed the face, opposite the bottom 3, by which the sliders will be introduced on the pair of strips 1.
  • the sliders are made of an appropriate synthetic material, giving them a certain elasticity.
  • the sliders are brought one by one to the machine by any suitable feeding means (vibrating bowl, slides), capable of giving them a well-defined orientation. They are thus introduced between the two jaws 6 of the machine, which can pivot around axes 7 ( Figure 1).
  • Appropriate control means then pivot the two jaws, of which the heels 8, by pinching the cheeks 4, then cause the opening of the cursor, by elastic folding along the median line of its bottom 3 (FIG.
  • FIGS. 5 and 6 reference is made at 9 to the rotor mentioned above and provided at its periphery with housings 10 opening in the radial direction and suitable for receiving the sliders (generally referenced at 11).
  • the rotor 9 can be driven step by step, for example by means of a ratchet wheel (not shown) actuated itself by a jack controlled in synchronism with the supply of the successive sliders 11, as well as with the welding rate.
  • stator 12 Along a part of the periphery of the rotor 9, between the location of arrival of the sliders 11 (lower part of FIG. 5) and the path followed by the closure strips 1, extends an arcuate stator 12.
  • This stator has a bearing surface 13 with respect to the rotor 9 and it is eccentric with respect to the rotor so that the space between this surface 13 and the bottom 14 of the housings 10 goes gradually decreasing in the direction rotor rotation (arrow 15).
  • the bottom 14 of the housings has a particular shape to constitute what has been called above "the system of ramps or the like"; it has, as visible in FIG. 6, a doubly V-shaped profile, with two pairs of ramps 16 and 17, separated by a bearing 18.
  • the occupied housing 14 drives the cursor 11 in the direction of the arrow 15 and the edges of the part of the cursor which remains outside the rotor, that is to say the edges of this which have been called above "the insertion face of the sliders" are pressed against the bearing surface 13 of the stator 12. Because the space provided between this surface 13 and the bottom 14 of the housing 10 gradually decreases during rotation in the direction of the arrow 15, the edges of the outer cheeks 4 of the cursor are caused to slide along the ramps 17 of the bottom 14 of the housing, which causes the progressive opening of the cursor, to the position shown at the top of Figure 6.
  • a machine according to the invention is of a simplified constitution and also of a very simple and practically continuous operation; in particular, it does not require any adjustment and it has been found that it is also very weak in operation.
  • FIGS. 7a and 7b there is shown, as a variant, another type of cursor, referenced at 22, and which can also be placed, by a machine according to the invention.
  • these sliders have been provided with a pair of ears 23, a rune provided at one end of the slider on one of its lateral legs and the other on the other leg but at the opposite end.
  • These ears can thus be guided by grooves or by an appropriate ramp provided on the surface 13 of the stator, in such a way that they are progressively separated from one another to cause the opening of the cursor 22 during its movement in the direction of arrow 15.
  • the operation of the machine would therefore be essentially the same as that which has just been described.
