Definitions

  • the present invention relates generally to a machine for the manufacture of plastic bags consisting of two superimposed sheets welded along their lateral edges, the bottom remaining open or being closed by a welding or folding line, these bags being equipped with profiled coupling elements extending along the edges of their opening and capable of being coupled by elastic deformation by pressure under the effect of the sliding of a slider, this machine comprising, inter alia, in known manner , downstream of an extruder producing the sheets, on the one hand an apparatus for automatically placing sliders, in operational position, on profiled coupling elements which extend along the longitudinal edges of two sheets superimposed in movement, and on the other hand, a welding and cutting blade suitable for carrying out at the desired rate, and this during periodic stops in the running of the sheets, transverse welding lines constituting the side edges of the bags.
  • Said profiled coupling elements can be extruded at the same time as the sheet and constitute an integral part thereof, or be produced separately and be attached continuously to the respective longitudinal edges of the sheets, by welding or by bonding.
  • a suitable device such as for example that which is the subject of French patent application filed in the name of the Applicant October 14, 1980 under No. 80 21974, automatically performs the laying of said sliders to come, in the operational position , cover said coupling coupling elements on each bag width.
  • This automatic positioning of the sliders is carried out - of course also at the desired rate - upstream of the welding station and cross section of the sheets.
  • One of the aims of the present invention is to avoid the disadvantage of having to move the slider installation device, which is relatively heavy and bulky, more or less frequently, and to ensure that '' it can be fixed, while also automatically and safely avoiding the risk of any operational incident.
  • a machine of the general type indicated at the beginning is, in accordance with the present invention, characterized in that it further comprises, between said apparatus for placing cursors and said welding and cutting blade, a positioning apparatus automatic said sliders on said coupling coupling elements, adapted to bring them at a determined distance from the location provided for said transverse welding lines, regardless of the width provided for said bags.
  • the slider fitting device can be fixed, which can be more particularly advantageous when it is planned that this device works on moving sheets of which at least part of the path is vertical, an arrangement which makes it more simple and more reliable means of supplying the device with sliders, since these then move by simple gravity in a vertical chute.
  • an additional characteristic of a machine according to the invention may consist in that said slider fitting device is fixed and operates on a vertical part of the path of the sheets in movement.
  • the present invention also relates, and more particularly, to the structure and the operating mode of said automatic cursor positioning device.
  • said device will be characterized in that it essentially comprises a chassis, a passage provided for allowing the scrolling of said profiled coupling elements which extend along the edges longitudinal of two superimposed sheets, and, on either side of this passage, two facing rollers, mounted at the free ends of two pivoting arms and capable, among other movements, of moving away from one of the other, to allow free passage to a slider mounted on said profiled elements, or to approach one another, and momentarily prevent this passage, which, the scrolling of the sheets continuing " causes a longitudinal displacement, d 'determined amplitude, of said cursor on said elements.
  • Such a cursor positioning device in accordance with the present invention has other interesting characteristics, which will be more explicitly discussed below, and in particular means allowing the delivery of finished bags, open or closed, as well as carrying out a testing the proper functioning of each cursor.
  • the chassis of the device has been referenced in 1 and the two rollers, forming between them a passage for the coupling profiles, in 2.
  • These rollers which are rotatable around axes 2a, and have a groove 2b, are each mounted at the free end of an arm 3 mounted to pivot about an axis 4.
  • the other end of the arms 3 is connected by a link 5 to a common axis 6 secured to a mobile support 7.
  • the axes articulated connecting the arms 3 to the links 5 have been referenced at 8.
  • the position, in abutment, of the movable support 7 relative to the chassis 1, can be adjusted by the rotation of a knurled button 9 mounted at the end of a screw 10 screwed into the support and whose free end comes abut, at 11, on one end of the chassis 1.
  • a lock nut 12 allows, after adjustment, and by tightening on the wall 13 of the support 7, to fix the position of the screw 10 relative to the support 7.
  • the maximum degree of pinching of the two rollers 2 can be adjusted one on the other.
  • the displacement of the mobile support 7, which will control the pivoting of the links 5 and levers 3, and consequently the opening and closing of the rollers 2, is produced by a pneumatic cylinder 14 fixed relative to the chassis 1 and whose threaded end 15 of the piston rod, on which is also mounted an adjusting lock nut 16, is screwed into said support.
  • Automatic feeding control of the cylinder of the jack 14 is effected by means of a solenoid valve and all appropriate detector means (not shown), this as a function of the progress and periodic stops of the superimposed sheets of plastic material in movement (in the direction arrow F), which have been referenced in 17 and bear on their longitudinal free edges of the coupling profile elements 18 (in FIG. 2, a slider mounted in the operational position on the profiles 18 has been referenced in 19).
  • the hinge pins 4 are integral with a carriage 20 mounted to slide on the chassis 1.
  • the sliding of the carriage 20 relative to the chassis 1 is ensured on each side by lateral slides 21, with retention ensured by the intermediate two lateral grooves 22 of the chassis, on each of which slides the head 23 of a screw 24 fixed in said carriage 20.
  • the carriage 20 can be resiliently locked on the frame 1 by the rounded end 25, urged outward by an internal spring, with an elastic lock screw 26 to nut 27 fixed on the carriage 20, this end being able to occupy one of two notches 28 or 29 of the chassis 1.
  • the operation of the device which has just been described is as follows: a cursor 19 having arrived in the position shown in FIG. 3, the jack 14 was controlled, during the preceding cycle time, so that its rod is retracted as far as possible into its body, which has brought the movable support 7 into the front stop position shown in FIG. 2. The rounded end 25 of the elastic lock 26 then occupies the notch 29.
  • rollers and the various axes of the system are in the position for which the references which designate them, and which are the same as in the other figures, are assigned the index 1 (and so on: 2 , 3 and 4 for the following times of the operating cycle).
  • the stopping of the sheets 17 is produced by an electric brake acting on the rollers, with production of a control signal for the second cycle time: the rod of the jack 14 comes out and moves the movable support 7 from the chassis 1 , which causes the rollers 2 to open (their axes come in 2a 2 in FIG. 3).
  • rollers 2 (axes in position 2a 3 ) are then always in the open position, but behind the cursor 1 ' 9.
  • the jack 14 is then controlled in the opposite direction, which causes the rollers 2 to close behind the slider 19.
  • the rollers are then in position 2a 4 in FIG. 3 (fourth step of the cycle).
  • This arrangement has the advantage of testing the correct operation of the slider 19 which, if it is defective or improperly engaged on the sections 18, is ejected, which allows an easy and rapid observation of the defect. In addition, this leaves enough room at the rear end of the profiles 18 (behind the cursor) to allow the welding point to be made on the profiles, this welding point constituting a stop for the cursor on the future. bag.
  • Open bags can be obtained (with the exception of the short length closed at the rear, which has just been mentioned), if the rollers 2, being in the maximum closed position, do not cause an inter-engagement of the profiles coupling 18 during the first time of the cycle. Indeed, when the cursor is blocked by the rollers 2 in position 2 . and as the sheets advance, this cursor causes disengagement of the profiles 18, which are coupled at the level of the device for installing the cursors.
  • the invention makes it possible to obtain open or closed bags, of variable widths, without it it is necessary to modify the distance which separates the device for placing cursors from the welding and cutting blade, with cursors whose correct functioning has been tested, and which are always located at a determined distance from the rear end of the profiles, on each bag.
