Definitions

  • the subject of the present invention is a device for welding and cutting at least one horn of a plastic bag, of the type obtained from a cushion filled with liquid, device in which the bag is placed on a flat surface in a compression assembly ensuring its positioning and its maintenance, said horn being welded by a welding jaw and cut out.
  • the products thus obtained are generally in the form of sachets having a flat base and provided at their upper part with two horns or corners.
  • patent FR-A-1 332 651 describes a shaping device in which the horns of the cushions are folded over the body of the latter and glued later. There is therefore no cutting and this requires the folding and gluing phase.
  • patent FR-A-1 259 662 describes a welding and cutting device according to the preamble of claim 1, but of complex structure and unreliable in practice.
  • the object of the present invention is to propose a device for obtaining this result.
  • the two lower corners will have been previously welded and cut to give stability to the bag.
  • the device further comprises a device for supplying and supplying cushions of flexible synthetic material filled with liquid upstream of an assembly for shaping said cushions into individual sachets each provided with a handle, said cushions being brought through a chute to a conveyor belt supporting cages integral in translation with said belt, each cage having to receive a cushion for its final conformation, and in that it comprises a share a rocker at the end of the chute, said rocker successively receiving each cushion coming from the chute and being tilted, to release the cushion which it supports, during the passage of each cage of the conveyor belt vertically over the rocker , and on the other hand a set allowing successively to retain and release each cushion individually on the chute before they reach t to the rocker, said assembly being slaved to the rocker so as to retain the next cushion when the rocker already contains a cushion and makes it fall into the cage which is presented and to release said cushion so that it is presented on the rocker when it returns to position.
  • FIG. 1 There is shown schematically in Figure 1 a bag (101) provided with a handle or stiffening element (102) which has been attached thereto.
  • the object of the invention is to further improve the structure of the intermediate bag (104).
  • the bags (104) are arranged, after the cutting of the lower horns, one by one on a conveyor belt (106) operating in an indexed manner which brings them to a compression assembly (107) ensuring their maintenance and their positioning in order to carry out the desired welding and cutting operations.
  • This compression assembly is composed of a side plate (108), a stop plate (109) and a closure angle (110).
  • the compression assembly forms a partially open cage along one of the sides (opposite the ventuose).
  • the fixed side plate (111) remains (without light), as well as the stop plate (109), but the angle (112) is more enveloping, so that the assembly of restraint is a cage almost closed so as to ensure by itself the maintenance and positioning of the bag without using a suction cup.
  • the upper horn (105) of the bag is disposed between the two articulated jaws (116, 117) of a welding clamp (118) which also includes an integrated cutting tool (119).
  • the welding and cutting takes place automatically from the final positioning of the bag, for example under the effect of the suction cup (114) as shown in FIG. 3b.
  • the clamp (118), the suction cup (114), the plate (109) and the plates (110, respectively 112) are released or retracted, the bag being released by the conveyor belt at the same time as the next one is positioned.
  • the compression assembly is a rigid cage (120), into which the cushions fall.
  • the cage is integral in translation with the conveyor belt (121). ).
  • the pinching and cutting of the lower horns and of one of the upper horns are carried out while the cushion is in said cage.
  • the finished bag is evacuated from the cage when the latter tips over at the level of the return roller of the conveyor belt.
  • FIGS. 5 and 6 represent a device arranged upstream of the device of FIG. 4.
  • a proximity detector When each cage is under the scale, a proximity detector, not shown, triggers the tilting of the scale around its axis (203) by means of a jack (204) whose yoke (205) is connected to the frame (206) and whose rod (207) is connected by a link (208) to the axis (203).
  • the output or withdrawal of the cylinder rod therefore respectively control the tilting or return to the position of the rocker.
  • the latter may also include a chute profile (209) which will come in line with the chute (202), and a holding jaw (210) articulated on the body of the rocker along an axis (211).
  • This jaw serves to keep the cushion on the rocker as long as possible, so that it falls as close as possible to the vertical.
  • the opening of the jaw (210) is controlled by a roller integral in rotation with the rocker, and the displacement of which, during tilting, causes a lever which releases the jaw.
  • the jaw is also returned by a return spring (212) fixed on the one hand to the jaw and on the other hand to the rocker (200).
  • the final position of the rocker (200 ') and the jaw (210') is shown in dotted lines when the cushion is released.
  • the cushions come from a chute (202).
  • a conventional tilt adjustment device (213) essentially consisting of an axis that can occupy any position. in a curved light that can be immobilized in each of them.
  • the assembly (201) essentially consists of a double arm (214) articulated around an axis (215) which pivots in a yoke (216) integral with the frame.
  • the rotation of the double arm is controlled by a lever (217) and a connecting rod assembly (218) crank (219).
  • the lever (217) is controlled in rotation about its axis (220) on the one hand by a lug (221) integral with the rocker (200) and on the other hand a return spring (222).
  • the ends of the arms (223, 224) will be protected by a flexible and rounded material.
