Definitions

  • tacking glues a packaging process consists of heating the glue and arranging it in an envelope by a coextrusion technique.
  • the liquid or pasty glue and the material capable of forming the envelope pass through a nozzle, the material of the envelope surrounding the glue, to form at the outlet a flange surrounded by an envelope.
  • the bead is ejected at the outlet of the nozzle in a substantially horizontal direction.
  • the bead At the outlet of the nozzle, the bead is immersed in a cooling liquid, in particular water. Before the bead is completely solidified, it passes through cutting means to be formed in the form of cartons. Following, the pudding or the berlingots are kept immersed until complete cooling and the transition to the solid state of all the material. Insofar as the glue is surrounded by an envelope made of a chosen material to quickly solidify, even if the glue does not solidify quickly, the latter is protected during its cooling phase by the envelope so that the risk of tampering with the glue is limited. Between the nozzle and the cutting means, rollers or the like are generally provided to guide the coil. This packaging technique allows to obtain relatively large berlingots, for example of the order of 5 cm long or more and 2 to 3 cm wide or more.
  • non-tacking glues these are packaged without an outer shell as long as they are “tacky”, which also reduces costs.
  • the "non-tackantes" glues are packaged in the form of small pellets, for example with a section of the order of 1 cm 2 and a thickness of the order of a few millimeters.
  • the liquid or pasty adhesive is placed in the form of pellets on a conveyor on which it cools.
  • the lower surface of the conveyor is cooled, for example by contact or spraying with a coolant, in order to reduce the cooling time of the glue.
  • the glue pellets are solid and can be collected in bags.
  • the liquid or pasty adhesive passes through one or more openings so as to form one or more cords which are severed at the outlet by a rotary knife which scrapes the surface at which the openings open.
  • the outlet of the orifices opens into a container containing a coolant, in particular water, in a substantially horizontal direction.
  • a coolant in particular water
  • the present invention aims to overcome the drawbacks of the prior art by providing a device for packaging a hot melt material, suitable for so-called "non-tackantes" glues, for conditioning the material in the form of a volume of significant dimensions without the matter being altered.
  • the device comprises at least one coolant inlet disposed near the arrival of the product to be packaged, the shapes of which are adapted to eject the cooling liquid in a direction parallel to the direction of ejection of the product to be packaged.
  • FIG. 2 is a section illustrating in detail a packaging device according to one embodiment.
  • the packaged product according to the invention is in the solid state at room temperature and must be heated to be activated in the case of an adhesive, or be worked in the liquid or pasty state.
  • product means a single product or a mixture of products.
  • This inlet 16 is connected to the manufacturing station 12. At least one pump 18 and possibly a filter 19, a heat exchanger 20 may be provided at the duct 22 connecting the manufacturing station 12 and the conditioning device 10 to respectively cause the flow, filter and maintain the product to be conditioned at a temperature allowing it to flow.
  • flow control means 24 are provided upstream and near the inlet 16, for example a volumetric pump, to control the flow rate of the product to be packaged.
  • the conditioning device 10 comprises a reservoir 26 containing a cooling liquid, in particular water in which the inlet 16 of the product to be conditioned opens.
  • the inlet 16 is disposed in the lower part of the tank, substantially in the central part and has shapes for ejecting the product to be packaged in the form of a flange 32 in a substantially vertical direction upwards.
  • This arrangement makes it possible to take advantage of the natural upward movement of the product to be conditioned in order to accelerate the ejection speed, which contributes to obtaining a packaged product having a large volume.
  • the temperature gradient of the coolant being vertical, the points of the side wall of the coil 32 at the same altitude are subjected to substantially identical temperatures. This configuration makes it possible to obtain a homogeneous temperature around the bead 32, which contributes to limiting the appearance of stresses inside the product to be conditioned during the solidification phase and to avoiding friction at the outlet of the die.
  • the conditioning device comprises, in the vertical direction of the inlet 16, means 34 for cutting the bead 32 in such a way as to cut it to form bells 36 or means for making a precut at the bead to delimit cartons.
  • the evacuation 50 has a funnel or nozzle shape so as to increase the flow velocity of the product and the liquid at the outlet, which tends to increase the scrolling speed of the strand by suction.
  • the increase in the speed of scrolling of the flange and the large influx of the coolant makes it possible to obtain rapid solidification of the product and to avoid the risk of alterations. Thus, it is possible to obtain products of large dimensions.
  • the boxes of product can be conveyed by any appropriate means.
