Definitions

  • the present invention relates to the positioning of the lids on the neck of the containers on which they must be heat sealed before the actual heat sealing is carried out, in an automatic packaging line.
  • the lids which are generally supplied in a stack, are taken one by one by a sampling device called in this case unstacking device and placed on the neck of a container brought by a conveyor belt or similar, the container with its cover are then transferred by means of the transport system to the heat-sealing station where the closure of the container by heat-sealing must be carried out on the latter of the cover placed on its neck.
  • unstacking device a sampling device
  • the container with its cover are then transferred by means of the transport system to the heat-sealing station where the closure of the container by heat-sealing must be carried out on the latter of the cover placed on its neck.
  • the lids which are very light, are moved or even removed from the neck during their transfer from the unstacking station to the heat sealing station.
  • US Pat. No. 3,908,340 shows a device for fixing lids on containers, in which the positioning of the lids is carried out on the containers, while the latter are in movement and in which a prepositioning of the lids is carried out. by means of a welding point made on these at the end of their installation on the container.
  • This device does not completely avoid displacement or improper positioning of the lids, because the prepositioning is only carried out at the end of the establishment of the lids. It therefore does not ensure precise positioning of the lids on the neck of the containers.
  • GB-A-1 280 757 describes a method for positioning lids or the like on the neck of containers to which they are intended to be fixed by heat sealing, which consists in simultaneously unstacking the lids, placing them in place on the neck of each container and fixing them thereon by producing at least one welding point, the container remaining fixed during this step.
  • the device for implementing this method comprises a device for removing the lids and a positioning device carrying a heating element capable of producing at least one weld point on the lid deposited on the neck of a container simultaneously with the placing of the latter on this repicient by the sampling device, in which the sampling device is a destacking device formed by at least one suction cup or the like movable vertically from a high position in which it is capable of coming to collect a cover at the bottom of a stack of lids, in a low position in which it is able to place the lidded seal on the neck of a container, this suction cup performing, during this movement, a rotation of 180 °.
  • the heating block and the gripping member of the lids are independent of each other, which makes the correct provisional fixing of the lids more hazardous.
  • this device on the one hand, cannot be used with container necks having significant differences in diameter and, on the other hand, does not allow two diametrically opposite welding points to be carried out, which would ensure a better provisional holding of the operator. cule on the neck of the container.
  • the object of the present invention is therefore to remedy these drawbacks and to provide a device making it possible to obtain precise positioning of the seal on its container before the heat-sealing operation is carried out, usable with containers whose neck dimensions are very different. .
  • the heating element consists of a block, the part of which capable of coming into contact with the cover is located at a distance from the axis of rotation of the suction cup substantially equal to the distance separating the end of this suction cup from its axis of rotation, the heating block is rotatably mounted around the axis of rotation of the suction cup of the sampling device, it is able to pivot relative to this suction cup so as to be substantially parallel to the suction cup in the low position of the suction cup but angularly offset with respect to this suction cup in the high position thereof, so as not to come into contact with the lids located in the supply magazine, the positioning device is formed of a first block in the shape of a stirrup mounted rotatably on the pivot axis of the suction cup and comprising two wings delimiting between them an abutment face and a passage allowing the deployment acement of the suction cup during its pivoting and of a second block comprising a heating cartridge and also having two
  • the two abutment faces form an angle between them substantially equal to 90 °.
  • This packaging line consists essentially of an endless conveyor 2 on the path of which are arranged different work stations 3, 4, 5, in this case a station 3 for loading containers 7 to be closed, a station 4 for removal of the lids 8 and placement of these on the neck of the containers 7 as well as a heat-sealing station 5 for these lids 8 on the containers 7.
  • the picking station 4 is in this case a destacking station and is essentially formed by a support frame 6 on which are fixed a magazine 9, arranged above the conveyor 2 and in which the lids 8 are stacked, and a device 10 which is able to collect the lids 8 stacked in the magazine 9 one by one and to deposit them on the containers 7.
  • This device 10 comprises a carriage 11 mounted movable vertically, along two columns 12, and actuated by a jack 13.
  • this carriage 11 At the front of this carriage 11 extends a cylindrical rod 17 of horizontal axis 16 and perpendicular to the longitudinal direction of the conveyor 2, this rod 17 being rotatably mounted in the carriage 11.
  • a stirrup 15 comprising two wings 15a and a stop face 15b between these two wings is rotatably mounted on the rod 17 at the front end of the latter.
  • a pneumatic suction cup 21 On this rod 17 is also fixed a pneumatic suction cup 21, the feeding system of which is not shown in the drawing for greater clarity.
  • This suction cup 21 is arranged in the interval between the two wings 15a of the stirrup 15 and is able to pivot between these wings 15a when the stirrup pivots relative to the rod 17.
  • This heating block 23 also comprises wings 23a delimiting between them an interval within which the suction cup 21 can move during the relative pivoting of the stirrup 15 and of the rod 17 and an abutment face 23c between these two wings.
  • Each wing 23a of the block 23 is provided with a projection 23b, the end of which is situated at the same distance from the axis of rotation 16 as the end of the suction cup 21, this distance being equal to that separating the axis of rotation 16 of the cover 8 located at the bottom of the magazine 4, in the high position of the device 10 for picking up and prepositioning, and to that separating the axis of rotation 16 from the upper end of the container 7 located in below the sampling device 10, in the low position thereof.
  • the projections 23b are oriented horizontally in the upper position of the sampling device 10 and are oriented vertically in the lower position thereof.
  • a heating cartridge 24 of a type known per se.
  • the block 23 is made of a material which conducts heat well, and in particular of a metallic material so that the projections 23b of its wings are heated by the cartridge 24.
  • a roller (not shown in the drawing) whose axis of rotation 18 is eccentric relative to the axis of rotation 16 of the cylindrical rod 17 (see FIGS. 3 and 4 ).
  • This roller cooperates, in a manner known per se, with a cam profile 19 produced on the frame 6 (see FIGS. 3 and 4) and comprising two edges at 90 ° 20, this roller being pushed against the cam profile by a spring. (not shown in the drawing).
  • the axis of rotation 18 of the roller is located below the axis of rotation 16 of the rod 17 when the carriage 11 is in the high position (see Figure 3) and is at opposite located above the axis of rotation (16) of this rod 17 when the carriage 11 is in the low position (see FIG. 4).
  • the rod 17 and the suction cup 21 carry out according to the same process two rotations upwards of 90 °, that is to say an overall rotation of 180 ° while the pre-positioning block performs only one rotation towards the top of 90 °, the suction cup 21 causing the stirrup 15 and therefore the block 23 during the second rotation, by its abutment against the abutment face 15b of this stirrup located between the two wings 15a thereof.
  • the suction cup 21 takes up by suction the cover 8 which is located at the lower end of the stack of the magazine 9.
  • the device 10 then descends, and the suction cup 21 simultaneously pivots downwards as explained above so as to bring the cover 8 which it has just grasped onto the neck of the container 7 brought by the transporter 2.
  • the cover 8 is heat sealed in two places 8a simultaneously with its positioning on the container 7 by the two heated projections 23b produced on the block 23, this heat-sealing being sufficient to ensure the prepositioning of the cover 8 on the container and guaranteeing that it is properly maintained ci in position when passing from the unstacking station 4 to the heat sealing station 5 where the cover 8 will be permanently fixed to the container.
  • the welding carried out on the cover is carried out not at one or two points, but on portions of lines and is therefore more efficient than spot welds.
  • the shape of these projections 23b allows adaptation of the device. tif with several cover diameters and is therefore particularly advantageous.
  • the relative angle of rotation between the block 23 and the suction cup 21 could have a value other than 90 ° (for example by providing an inclined surface between the wings 15a of the stirrup), the essential being that the projections 23b of the block 23 do not come into contact with the lids 8 housed in the magazine 9 when the sampling device 10 is in its high position.
