Definitions

  • the present invention concerns a method and an installation for packaging an adhesive product according to the characterizing clauses of claims 1 and 10.
  • the present invention also concerns a packaged adhesive product or similar products.
  • an adhesive product for example in the form of a hot melt adhesive
  • the adhesive product must be packed into suitable shipping containers so that the adhesive product can be shipped from the place of manufacture to the place of use. Therefore, an important function of the shipping container is to keep the means used for transportation and possibly storage from contact with the adhesive product.
  • the shipping container also must be designed so that the adhesive product can be completely removed, i.e., so that it does not adhere to the inside walls of the container.
  • US Patent 5,373,582 describes a method and an installation of the above type wherein a plastic film is first continuously formed by means of a film bonding device into a hollow tubular body in a filling station for the adhesive product to be packaged.
  • the leading end of the tubular body in the direction of tube formation, is first contracted into sections by means of constricting rolls, so that the tubular body is closed at one end.
  • the liquid adhesive product is then filled into the tubular body closed at one end.
  • a next section of the continuously formed tubular body is again contracted by the constricting rolls so as to make a separate packet filled with the adhesive product. This packet is cooled at a predetermined temperature before being separated from the continuously formed tubular body.
  • This disclosed method and installation have the disadvantage that a separate plastic film must be provided for the protective sheath, which must be formed into a hollow tubular body by means of a complicated manufacturing method. Because of this complicated manufacturing method, the filling installation itself must be provided with tooling and/or additional components, which increases the cost of the filling installation.
  • US Patent 3,469,363 also describes a method and an installation of similar operation and construction to those mentioned in reference to the above US Patent 5,373,682 [sic? 5,373,582? -- Tr. Ed.]. An essential difference is that the tubular body is not formed from a plastic film, but from two plastic films. Thus the problems explained in reference to US Patent 5,373,682 [sic? -- Tr. Ed.] are doubled.
  • US Patent 3,327,349 describes an extrusion tool that can apply a sheath on the extruded product by means of a co-extrusion process.
  • the material to be sheathed is in a viscous state so that the protective sheath can be applied readily to the adhesive product.
  • the object is achieved by the characteristics of claim 1.
  • the co-extrusion of the liquid adhesive product and the nonadhesive material comprising the protective sheath in an extrusion tool permits a very simple and profitable packaging of the adhesive product. This method does not require the complicated manipulations needed for the two methods described in the US Patents 5,373,682 [sic? -- Tr. Ed.] and 3,469,363.
  • the extruded product can be subjected to a very wide range of treatments. It would be particularly advantageous to guide the extruded product for a predetermined distance in order to solidify it.
  • the solidification process can consist of a procedure of cooling the extruded product comprised of the liquid adhesive product and the protective sheath for the adhesive product.
  • One particularly simple possibility for the cooling process is to immerse the extruded product obtained by the co-extrusion process in a water bath.
  • the extruded product can be introduced directly into the water bath.
  • the design can be such that the extrusion tool provided for the co-extrusion process discharges below the water level in the water bath, so that the emerging extruded product is immediately completely surrounded by water when it emerges.
  • the solidification path be connected directly to the outlet of the extruded product from the extrusion tooling.
  • the solidification path extend spirally in one plane, and preferably in a horizontal plane.
  • the solidification process can consist of cooling in the case where the adhesive product had been heated in order to liquefy it.
  • the solidification path consists of a cooling path.
  • a cooling path consisting of special cooling installations, for example cold-air fans, etc.
  • a particularly simple possibility that additionally ensures gentle handling of the product is to provide a cooling path in the form of a water bath.
  • the cooling bath can use water or any other liquid that is chemically neutral to the extruded product.
  • the liquid of the cooling bath also can be used to treat the protective sheath of the extruded product.
  • the outlet of the extruded product preferably can discharge directly in the water bath.
  • the outlet of the extruded product from the extrusion tool discharges under the water in the water bath, so that, as explained above, the extruded product emerging from the extrusion tool is immediately completely surrounded by water when it emerges.
  • a very great variety of conveying means can be used to convey the extruded product in the water bath. Because the extruded product leaving the extrusion tool is still deformable because of the residual heat, the conveying method must be carried out gently. To this end, the extruded product can be conveyed along the cooling path, at least part way, by means of water spray nozzles. Obviously the conveying method also can be combined with other conveying means.
  • a constricting device is provided on the solidification path to form the extruded product leaving the extrusion tool into a chain of separated packets connected together before the final solidification.
  • This constricting device for example can consist of two star-shaped rollers that receive between them the extruded product leaving the extrusion tool. Depending on the desired length of the different packets, these star-shaped rollers have several ribs extending radially outward over the entire circumference. The two star-shaped rollers are arranged so that the two opposing ribs receive the extruded product between them.
  • the extruded product is solidified by cooling in a water bath, it is particularly advantageous to place the constricting device between the extruded product outlet and the extraction rollers in the water bath.
  • the extrusion tool can be an extrusion head having an inlet port for the adhesive product and an outlet port for the adhesive product connected together at least in a practically coaxial manner, and also, situated between those inlet and outlet ports, an annular outlet port for the nonadhesive protective sheath material.
  • the nonadhesive protective sheath can be chemically neutral to the adhesive product.
  • the protective sheath also can be chemically compatible with the adhesive product.
  • the protective sheath also can consist of a material that is outwardly nonadhesive, but reacts with the adhesive product at an interface layer between the protective sheath and the adhesive product.
  • the protective sheath also can consist of a material that has nonadhesive properties outwardly, but reacts with the adhesive product at an interface layer between the protective sheath and the adhesive product. In all these cases, it is preferable if the protective sheath can be processed along with the adhesive product during the subsequent use of the adhesive product without needing to be detached from the adhesive product.
  • the protective sheath should comprise between about 1 to 5% by weight of the adhesive product.
  • adhesive product includes also fabrics whose function is not to connect two or several components by adhesion, but to provide an adhesive property as a result of their chemical composition. Such materials also can be packaged in a simple manner by the method and the installation according to the invention. The proposed invention is shown to be particularly advantageous in combination with hot melt adhesives.
  • the installation according to the invention for packaging an adhesive product or similar products has a tank 10 containing the adhesive product.
  • the adhesive product can be added to this tank 10 in the form of granules, powder, etc., and can be liquefied there by means of a heating device, not shown in detail.
  • the adhesive product to be packaged also can be added to the tank already in liquid form and kept there in a liquid state by means of the heating device.
  • the liquid adhesive product is transferred through a connecting line 12 to a metering pump 20.
  • the adhesive product is transferred through a connecting line 22 to an extrusion device 30, the extrusion tool 32 of which will be described in greater detail below in reference to Figures 5 and 6.
  • the extrusion device 30 can have the known configuration of either a single-screw extruder or a double-screw extruder.
  • another tank 50 holds the nonadhesive material constituting the protective sheath.
  • the nonadhesive material can be added to the tank 50 in the form of granules, powder, etc., and can be liquefied there by means of a heating device, not shown in detail.
  • the nonadhesive material comprising the protective sheath also can be added to the tank 50 already in liquid form and kept there in a liquid state by means of the heating device.
  • the nonadhesive material comprising the protective sheath is transferred to the extrusion device 30 through a connecting line 52.
  • the extruded product E continuously issuing from the extrusion device 30, or more particularly from the extrusion tool 32 (see Figure 4), and consisting of the adhesive product from the tank 10 and the nonadhesive protective sheath from the tank 50 in the form of a film enveloping the adhesive product is conveyed to a cooling device 60 composed of a passage containing water 62 and extending spirally in a plane, particularly in a horizontal plane, from the exterior; that is, from the extrusion device 30 toward the interior, as clearly shown in Figure 1.
  • the cooling device 60 is supported by a frame 64, which also supports the extrusion device 30.
  • the passage 62 of the water bath 60 can be formed by arranging a profile, having for example a U section, in a spiral in a horizontal plane. It is also possible to provide a vessel equipped with baffles extending spirally in order to form the passage 62.
  • the cooling path is 190 m long and is equipped with a tank or vessel 2.5 x 4.5 m in size.
  • the extruded product E After the extruded product E passes through the cooling path formed by the passage 62, the extruded product is extracted from the cooling device 60 obliquely upward by means of a conveyor belt 80, as shown in Figures 2 and 4. Upon leaving the passage 62, the extruded product E is dried along a drying path formed by the conveyor belt 80. The drying itself can be accomplished by providing a hot-air fan 90 above the drying path. At the end of the drying path formed by the conveyor belt 80 is a separating device 100 which separates the individual packets EP of the extruded product E.
  • the conveyor belt 80, the drying device 90, and the separating device 100 will be described in greater detail below in reference to Figure 4.
  • Figure 4 diagrams the arrangement of the extrusion device 30, the cooling ,device 60, the outlet conveyor belt 80, the drying device 90, and the separating device 100.
  • the extruded product E upon leaving the extrusion tool 32 of the extrusion device 30 immediately enters the water bath formed by the water passage 62, which extends spirally in a horizontal plane. In other words, the extrusion tool 32 discharges into the water bath so that the extruded product E upon leaving the extrusion tool 32 is completely surrounded by water.
  • Two constricting rollers 66a and 66b of a constricting device 66 are situated immediately by the extrusion tool 32 in the direction that the extruded product E is conveyed.
  • the constricting rollers 66a and 66b As shown in Figure 4, the constricting rollers 66a and 66b, the axes of rotation of which are essentially horizontal, have on each six ribs that extend radially outward and are spaced at an equal angular distance over the circumference of the axes of rotation.

  • the two constricting rollers 66a and 66b ensure a preliminary subdivision of the extruded product E leaving the extrusion tool 32 into separate packets of extruded product EP of identical size and shape, these packets being connected together in the form of a chain.
  • the constricting device 66 is followed by an extraction or conveying device 68 composed of two conveying rollers 68a and 68b. These two rollers 68a and 68b also are arranged parallel to one another in a manner similar to the constricting rollers 66a and 66b of the constricting device 66, so that their horizontally extending axes of rotation extend in the plane of the drawing of Figure 4 and are superposed in a vertical plane.
  • the extruded product packets EP pass through the two rollers 68a and 68b.
  • the conveying device 68 also serves to keep the extruded product E under water after it leaves the extrusion device 30.
  • the different extruded product packets EP After passing through the extraction device 68, the different extruded product packets EP reach the surface of the water bath and are conveyed by means of several water spray nozzles 70 along the passage 62.
  • the water needed for the water spray nozzles is taken from the passage 62 by a pump 72, which is shown schematically in Figure 4, and delivered to the spray nozzles 70.
  • Two connecting lines 74 and 76 are provided for this: the line 74 connects the pump 72 to the water bath of the cooling passage 62, and the line 76 connects the pump 72 to the spray nozzles 70.
  • the extruded product packets EP After passing through to the end of the spiral cooling passage 62, the extruded product packets EP reach the conveyor belt 80, which takes them from the cooling passage 62 to the separating device 100, which is described in greater detail below.
  • the conveyor belt 80 also forms part of the drying path provided with a drying device 90 above, for example a hot-air fan.
  • the hot-air fan 90 is connected to a hot-air source not shown in detail.
  • the conveyor belt 80 is followed by a separating device 100.
