Definitions

  • the invention relates to positioning devices for sliders on closures constituted by interlockable profiled elements; it relates more particularly because it is in this case that its applicationseems to offer most advantage, but not exclusively among these devices, to those intended for the positioning of sliders on closures of bags or pouches'in the course of manufacture from a folded sheet of plastic film advancing in intermittent manner, these closures being constituted by complementary profiled elements occurring at the edges of the sheet and capable of interpenetration or of interlocking, but also of being separated, the said elements having been previously fixed to the edges of the sheet in the form of strips or constituting integral parts of the sheet.
  • the slider positioning device comprises, a spacing member arranged in the direction of this movement of the profiled elements which keeps the complementary profiled elements spaced from one another, coacting with guide members constituting a first clamp adapted to immobilize the profiled elements on the spacer at the moment of positioning of the slider, and downstream of the spacing member, a second clamp adapted to mutually interlock these profiled elements and to ensure their immobilization for their said positioning, and on the other hand, ar-
  • a pusher device for the positioning of sliders on the said profiled elements perpendicularly to their longitudinal direction.
  • An object of the invention is to provide an improved mechanism for installing sliders by pressing them over the top edge of fastener strips in a single improved operation.
  • the slider positioning device is principally characterized by the fact that it comprises, mounted on a common support, two clamps, the pusher device and a common movable actuating member connecting the closing and opening of the two clamps on the advance and on the retreat respectively of the pusher, the assembly of these parts thus. constituting a single and compact apparatus.
  • the mobile actuating device is constituted by a shaft capable of rotation around it axis and bearing, on the one hand, a cam cooperating with thevend of the pusher, especially by means of a small roller borne by this end to produce alternate movements of the pusher in the direction of it axis against elastic return members, and on the other hand, cams inserted between the arms of the first and second above-said clamps, to cause the arms of these clamps to pivot around their respective pivoting points against theaction of elastic return members.
  • FIG. 2 shows in front view the device of FIG. 1, the clamps being open.
  • FIG. 3 shows a section of the device of FIG. 1, along the line III-III, with the first clamp closed.
  • FIG. 4 shows a section of the device of FIG. 1, along the line IVIV, with the pusher advanced.
  • FIG. 5 shows a section of the device of FIG. 1, along the line V--V with the second clamp closed.
  • closure elements can form part of strips fixed to the edges of the folded sheet or can be in a single part with the sheet, which can then be obtained with the closure elements by extrusion.
  • the closure elements are interlocked and the tube 1 thus obtained is flattened.
  • the tube is guided and driven (in the direction of the arrow F), upstream of the device 2, by wheels 7, 7a and is directed downstream of the device 2 in the partially open and partially closed state towards a cutting and welding apparatus (not shown) adapted to separate each bag from the rest of the tube and to form the lateraledgesof the said bag.
  • slider positioning device 2 shown in FIGS. 1 to 5, it comprises on one hand, and arranged in the direction of the movement of the profiled closure elements:
  • a spacing member 8 which holds separated, or separates, from one another, the complementary profiled elements 5 and 5a and cooperates with a guide device with movable jaws, adapted to form a first clamp 9, 9a, of which the jaws or arms are arranged on both sides of the spacer and which in their clampingposition, immobilize these profiled elements gripping their support on the spacer;
  • a second clamp 10, 10a which, in its closed position, cooperates with the immobilization of the profiled elements 5, 5a, in ensuring their partial reinterlocking;
  • This device includes a pusher l3 intended to engage a slider 14 (FIG. 4) on the said profiled elements 5, 50 when they are immobilized by the clamps 9, 9a and 10, 10a.
  • the separator member 8 is advantageously provided with two grooves 16, 16a in which are housed respectively the closure elements 5, a of the flattened tube 1 which form projections or.ribs on the inner surface of this tube.
  • the clamping which ensures the iminogrooves 17, 17a, whose height is selected so that this clamp whilst ensuring the interlocking of the complementary closure elements over a portion of their length which corresponds to the width of the clamp 10, exerts its final pressure which ensures the immobilization of the closure elements on the walls of their support l'outside the'said closure elements.
  • the pusher device 12 has advantageously included a channel 18 through which the slider 14 to be engaged are introduced on one surface 19, one by one facing the pusher 13 along a direction substantially perpendicular to the plane of the flattened tube 1 (FIG. 1 and 4).
  • the sliders 14, which are intended to slide astride the closure constituted by the profiled complementary elements 5, 5a, borne by the wall 6, 6a include a small plate 20 (FIG. 4) bearing, on one hand, two lateral walls 21, 21a bounding, on the inside of the slider a channel with convergent walls to ensure the interlocking of the enclosure elements, and on the other hand, a median partition 22 extending over a portion of the length of the slider (perpendicularly to the plane of FIG. 4 which shows the slider 14 in section), this partition forming a wedge and ensuring the de-interlocking of the said closure elements.
  • a small plate 20 bearing, on one hand, two lateral walls 21, 21a bounding, on the inside of the slider a channel with convergent walls to ensure the interlocking of the enclosure elements
  • a median partition 22 extending over a portion of the length of the slider (perpendicularly to the plane of FIG. 4 which shows the slider 14 in section), this partition forming a wedge and ensuring the de
  • the spacer 8, the two clamps 9, 9a and 10, 10a and the pusher device 12 are mounted on a common support 23, the closing, then opening of the clamps 9, 9a and 10, .10a, in synchronism with the advance, then the retreat of the pusher 13, being actuated by means of a common movable rotary cam shaft member 24, also mounted on the common support 23, the assembly of these parts thus constituting a single and compact apparatus.
  • the width of the spacer and the distance between the latter and the second clamp 10, 10a are determined so that the closure elements form between themselves, in the interval between the spacer and the second clamp when the latter is clamped, an angle which corresponds to the angle of the walls of the above-said channel inside the slider.
  • the above-said movable shaft member 24 is advantageously constituted by shaft bearing cams 26, 27 and 28 adapted to act respectively against the action of elastic return members 29, 30 and 31 on the clamps 9, 9a and 10, 10a and on the pusher 13.
  • clamps 19, 19a and 10, 10a are hinged at 32, 32a
  • the cams 26 and 27 and the elastic return members 29 and 30 are respectively arranged between the branches of the clamps 9, 9a and 10, 10a on both sides respectively of the hinges 32, 32a and 33, 33a of these branches on the support 23.
  • the return members 29 and 30 of the clamps are arranged so that they act in the direction of opening of the said clamps but it is evident that in reversing the positions of the cams 26, 27 and of the return members 29, 30 withrespect to the above-said hinges, it would be possible to arrange that the return members 29 and 30 act in the direction of closure of the clamps;
  • the pusher 13 (FIG. 4) is guided by the support 23 so that it can slide in a direction transverse with respect to the edge 3 of the flattened tube 1.
  • the corresponding elastic return member 31 is constituted by a spring interposed between the support 8 and a collar 34 borne by the pusher 13.
  • This pusher 13 is supported against the cam 28 by means of a roller 36.
  • the cams 26, 27 and 28 advantageously have shaped such that the closing, then the opening of the clamps 9, 9a and 10, 10a, on one hand, and the advance, and then the retreat of the pusher 13, on the other hand, are respectively caused by rotations in reverse directions of the shaft 24 between two predetermined angular positions (which positions are substantially separated by 90 in the example selected), the same shaft 24 effecting these rotations under the action of a jack 37 borne by the support 23 and placed in operation when the tube 1 is immobile, through a rack 38 by the same jack 37 and driving a pinion 39 borne by the same shaft 24.
  • the jack 37 can, for example, be actuated by a fluid under pressurerespectively introduced and evacuated through channels 41 and 42.
  • the jack 37 holds the shaft 24 in such a position that the clamps 9, 9a and 10, 10a are open and that the pusher 13 is withdrawn into the position shown in FIG. 1. The distance between the active ends of the clamps 10, 10a is then sufficient to enable the passage of the profiled elements 5, 5a with a slide 14 engaged on them.
  • a slider 14 has arrived through the channel 18 on the surface 19, formed on a ledge of the support 23, in a position for which the lateral walls 21,
  • the jack 37 communicates to the shaft 24 a rotation such that the clamps 9, 9a and 10, 10a close thereby immobilizing firmly the complementary elements 5, 5a, whilst the'pusher 13 effects its advance and engages by elastic deformation the slider 14 on the elements 5, 5a of the closure formed on the tube 1 (FIGS. 3, 4, 5).
  • a further intermittent movement of the tube 1 is preceded by a further rotation of of the shaft 24, in opposite direction caused by the jack and which results in the opening of ,the grippers 9, 9a and 10, 10a (the latter then allowing the slider to pass engaged on elements 5, 5a) and the withdrawal of the pusher 13.
  • a device for the positioning of sliders on closures constituted by interlockable profiled elements which advance in intermittent manner with respect to the said device which includes,
  • first clamp adapted to immobilize the elements on the spacer
  • second clamp adapted to interlock the elements and to immobilize them
