Definitions

  • the present invention relates to the gripping of hollow bodies such as bottles, flasks, jars, pots, tubes ... It relates more particularly to a new device for the gripping of such hollow bodies, in particular glass or plastic containers and their transfer to a surface treatment area at the end of manufacturing.
  • gripping devices have been proposed equipped with clamps which penetrate into the opening of the container and come to be applied on the internal face of the neck. In this case the coating can be total.
  • each gripping device must arrive opposite one of the regularly spaced containers arranged on a conveyor. There, the grippers of the gripper penetrate into the opening of the container to grasp it, and the assembly is then driven into the treatment area.
  • the gripping device which was reserved for it continues its circuit without being loaded. Arrived in the treatment zone, the clamps not protected by the container are then coated with the treatment product which comes to foul them so that their functioning can be disturbed.
  • the gripping device concerned returns to the loading station after having followed a complete cycle, its grippers, by entering another container, deposit coating product inside. This product can then alter the taste of the future contents of the container.
  • the invention provides a gripping device for hollow bodies which overcomes the aforementioned drawbacks.
  • This gripping device has a member which penetrates into the opening of the hollow body to grasp it without coming into contact with the outside of the hollow body and which, in the rest position, that is to say unloaded, is completely eclipsed in a scabbard.
  • the device according to the invention comprises a sheath, a rod, a return spring for the rod in the sheath, pinching means arranged at the end of the rod (see FR-A-2 315 323), and is characterized in that it further comprises a nut surrounding the rod, the rod and the nut being able to slide inside the sheath in order to partially exit therefrom and fully return to it, the nut being intended to abut against the upper end of the hollow body, a crown which can move radially so as to make the nut alternately secured to the rod or sheath depending on the position of the nut and the rod relative to the sheath, the nut being secured to the rod at the start of its exit stroke and at the end of its return stroke, while it is secured to the sheath during the exit stroke in the intermediate position corresponding to the abutment of the nut against the end of the hollow body, which allows the actuation of the means of pinching by a mo relative uvement of return of the rod relative to the nut,
  • the clamping means can be a clamp comprising two branches articulated around an axis and able to be brought closer to one another by pivoting around this axis with a view to introducing it into the opening of the hollow body and then to move aside to come and press firmly against the internal walls of the opening.
  • the clamp comprises two branches articulated along parallel axes carried by the nut and between which is disposed the end of the rod comprising an appendage having flanks inclined symmetrically relative to the axis of the rod, the corresponding ends of the branches having a corresponding profile part which bears on said flanks, so that said appendage during a longitudinal movement of the rod between the branches causes said branches to spread apart inside the hollow body, by pivoting around their axis, acting on these branches like a wedge.
  • the upper can include a second appendage with inclined sides, capable of coming to bear on a part of the heel of the branches in order to cause them to close and to keep them in the closed position.
  • This closure means can also be replaced by an elastic return means.
  • the pinching means can be a sleeve formed of several sections held together by return springs, and which move apart under the action of the rod or axis provided with one or more appendages with conical sides.
  • the crown making the nut alternately integral with the rod or the sheath may comprise a finger which, by the action of a spring is applied alternately on the rod or on the sheath.
  • the pinching means can be carried by the nut. They can then include branches articulated on the nut, which move apart during the relative movement of the rod relative to the nut during the ascent. These pinching means can also be carried by a pin fixed to the lower end of the rod. They can then comprise a sleeve formed of at least two sections which are housed between two conical faces, which can be the end of the axis and a ring, the sections deviating during the relative movement of the rod relative to the nuts.
  • a sheath 1 on which a collar 3 is fixed by a pin 2, by which it bears on an element 4 of an endless chain.
  • This sheath carries a sliding rod 5, the lower part of which has two grooves 6a and 6b terminated on either side by inclined sides 7a and 7b and 8a and 8b.
  • a hollow nut 9 Surrounding the rod, a hollow nut 9 carries, articulated on two axes 10a and 10b, two branches 11a and 11b which are housed in the grooves of the rod. A part of the profile of the branches is supported on the inclined sides 8a and 8b while a part of the profile of the heels is supported on the inclined sides 7a and 7b of the grooves.
  • the rod 5 At its upper end, the rod 5, provided with a washer 12, is recalled by a spring 13 interposed between this washer and the flange 3.
  • the bore of the bulging portion of the sheath has two sections bounded together by a shoulder F I : a first section of diameter d and a second section of larger diameter D.
  • the middle part of the rod 5 can slide in the nut 9 which slides itself inside the bore 14 of section d of the sleeve.
  • This nut 9 has flanks 15 of conical shape on which slides a crown 16 divided into three sectors, one of which 17 is provided in its center with a finger 18 passing through an opening 19 provided in the nut 9, to enter a groove 20 of rod 5 which it locks.
  • a ring 21 is applied against it by the action of a spring 22 fixed on the upper end of the nut 9.
  • the lower part of diameter D of the bore of the sleeve contains a ring 23 of internal diameter equal to d which can slide in the bore of diameter D of the sleeve, between the shoulder F 1 and a circlip 25, and the cross section of which upper form a truncated cone.
  • the device also has a toothed wheel 26 rigidly mounted on the sheath and which can drive the assembly, and consequently the hollow body, in rotation about its axis in the subsequent treatment zone.
  • an external member for example a stud mounted on an energetic spring on an articulated track which follows the advance movement of the gripping devices exerts a determined force P, for example greater than 15 kg on the upper end of the rod 5.
  • This rod descends by compressing the spring 13 driving the nut 9 through the shoulder F 2 as well as the sectors of the crown 16 whose finger 18 is engaged in the groove 20.
  • the descent of the rod 5 is then limited after a stroke of 85 millimeters for example by the presence of the object to be grasped which comes into contact with the underside 27 of the nut 9. At this time the crown 16 is in the bore of diameter D of the sleeve.
  • the spring 13 rises it at the same time as the ring 23 and the elements it contains.
  • the top of the ring 23 comes into contact with the shoulder F 1 ′ the crown 16, the nut 9 and the ring 20 continue to rise in the bore of diameter d until they come into abutment in the upper part of this bore .
  • the forceps have returned to their initial position, completely eclipsed in the sheath.
  • the ring 23 released from the action of the sectors of the crown returns to its initial low position.
  • the descent of the rod is no longer limited by the object to be grasped and the rod performs a full stroke.
  • the movement begins as in the case of the presence of an object and it continues as in the case of unloading, that is to say that the sectors of the crown 16 slide on the conical section of the ring 23 and there engage while applying against its walls, that the finger 18 again engages in the groove 20 of the rod 5 and locks it and that, after suppressing the action of the pusher, the rod 5, under the action of the spring rises, causing the assembly which comes to slip away in the sheath.
  • the clamp returned to its initial position completely eclipsed in the sheath.
  • the sprayed product for example by spraying, cannot reach and contaminate the penetrating organ.
  • Figures 5 and 6 show a variant of the gripping device in which the branches are replaced by an expandable sleeve formed of three sections.
  • the device has a structure similar to that of the device already described and comprises largely the same elements, namely: a sleeve 1 of bore D and d in which slide the nut 9, the crown 16 with three sectors, the ring 21 , the spring 22, the ring 23.
  • the rod 5 is provided with a pin 101 screwed onto it which ends in a double cone 102.
  • a ring 103 finished in the shape of a cone 104 slides freely on the pin 101.
  • a sleeve 105 formed of three sections 106, 107, 108 as shown in FIGS. 7 and 8.
  • the material of the sleeve can be a metal or a plastic material such as polyamides. It must withstand a temperature of the order of 250 ° C. in the case of a treatment for coating the containers with a plastic material for example.
  • the rod 5 descends, driving all of the elements inside the sheath as already described and the sleeve 105 enters the hollow body.
  • the crown 16 is located in the bore of diameter D of the sleeve.
