Definitions
- the invention relates to a method for inflating, separating or filling closely spaced film layers, without causing additional aids, such as valves, devices, funnels o.a. to be used.
- the invention relates in particular to a method and a device for penetrating film-like substrates or materials which lie airtight or directly on one another.
- valves, filling openings or spacers in the film to be processed in previous manufacturing steps at a suitable location, in order then to be able to connect corresponding cannulas or nozzles in the course of filling at this prepared location.
- corresponding material, time or financial expenses have to be taken into account and automation processes become correspondingly more complex and complex.
- the films finished by additional functions eg valves or filling openings
- the invention has for its object to provide an easy-to-use and undemanding to the film process and a device for filling plastic bags or separating closely spaced film layers available.
- Cutting edge having end of the one-sided helical, cylindrical hollow body introduced. Contrary to the conventional method with special openings for filling, an exact positioning on the workpiece foil is not required here. Either by suction through the hopper enclosing the cylindrical hollow body or by pressing with a padded surface, the films are pressed against the cutting surfaces of the helically shaped, cylindrical hollow body and fixed in position, as this corresponds to preferred embodiments of the invention.
- the cylindrical hollow body is brought into a controlled and defined rotational movement, whereby the cutting surface forming the end Before the screw-shaped, cylindrical hollow body for the time being roughened by rubbing the film selectively, then to grasp by the obtained roughness on the film surface with the tip of the cutting surface, the film and penetrate in a further rotational movement in the film.
- the film perpendicular to the first, arranged cutting surface, the film is opened in a circle and due to the thread structure of the cylindrical hollow body, the tip further rotated between the film layers or caused by the thread structure while the opened film layer is raised along the slope of the thread structure.
- a gaseous or liquid medium can be introduced between the film layers by the defined inserted cylindrical hollow body.
- a device for penetrating film-like substrates which are airtight, respectively, comprising a unilaterally helical cylindrical hollow body, wherein at least one cut surface of the helically-terminating part of the cylindrical hollow body is formed is through
- a rotatably mounted and correspondingly driven, tubular hollow cylinder is used, which is formed on one side, helical.
- the expiring end of this helical hollow cylinder is provided with, for example, two mutually perpendicular cutting surfaces, which merge with each other and extending in the circumference of the hollow cylinder to form a tip.
- the functions of these cutting surfaces are structured in such a way that the cutting surface defining the beginning of the process, which is arranged largely perpendicular to the drilling axis of the hollow cylinder, is responsible for the roughening and cutting of the material to be penetrated.
- the cutting edge of this cut surface is therefore also tapered on one side to the end expiring.
- the perpendicular thereto (hence parallel to the drilling axis of the hollow cylinder) second cutting surface is responsible in the further course for one, the circumference "of the hollow cylinder circular extending •-section.
- the converging tip surfaces of both cutting is such designed that the perpendicular through the An angle deviation of the first cutting surface relative to the perpendicular to the drilling axis of the hollow cylinder is decisive for the roughening and penetration behavior dull the angle, with respect to the perpendicular to the drilling axis, the more aggressively penetrates the helically shaped hollow cylinder, the foils and thus runs the risk of immediately penetrate or injure the underlying, underlying second film layer or violations
- Such constellations are therefore only f r resistant and thicker film materials for use come.
- a simple adaptation to different materials and material thicknesses can be achieved by the angle of inclination of the cutting surface according to a preferred embodiment of the device according to the invention.
- the degree of adhesion of a single film layer must be considered.
- the degree of adhesion of the individual film layers on the cylindrical hollow body can be determined by determining the extent of the thread forming the helical form.
- the device when at least one film layer is penetrated, it is further preferred that it is surrounded by a funnel-shaped part fixed by which the surrounding atmosphere can be sucked so that the applied to the helical cylindrical hollow body Foil layers are sucked by vacuum and thus in a defined and immovable position to the end of the helical cylindrical hollow body forming cut surfaces can be brought.
- the device according to the invention with a the end of the helical cylindrical hollow body forming cut surfaces opposite cushioning part is brought into connection so that this cushioning part, the film layers in a defined and immovable position brings to the end of the helical cylindrical hollow body forming cut surfaces.
- the opening created by the filling can or must be closed again. This can happen independently by gluing, welding or sealing with a closure in another operation. Likewise, these processes can also be integrated into the device and included in the control engineering process.
- the nature and design of the device according to the invention as well as the inventive process are in any case suitable to be integrated into a simple manual control device, so that a user-friendly and mobile apparatus for flexible filling of foil bags or for separating film layers is available.
- the helical hollow cylinder can be formed such that several openings are available within the threads.
- at least one opening opens near the cutting surface or along the thread, which communicates with the interior of the cylindrical hollow body. This makes it possible to separate several foil layers from each other in one operation and simultaneously fill a medium between the layers. If these holes are still freely released or closed by a tube running inside the hollow cylinder, different fill levels or filling media can also be introduced in the individual layers.
- a simple filling of two-layer foil bags is thus possible as well as a rinsing, separating and aerating of multilayer, connected by adhesion or material adhesion flat films for the purpose of optimized further processing of such film blanks.
- the device according to the invention comprises an inner, second, closed on one side hollow cylinder, wherein the second hollow cylinder determined by changing the position of the outlet opening for the gaseous or liquid medium between the separate film layers.
- FIG. 1 shows a composite device according to the invention for separating two-ply foils for carrying out the method according to the invention
- FIG. 2 shows the helical, cylindrical hollow body of the device according to the invention
- Fig. 3 screwed in two film layers, helical, cylindrical hollow body.
- FIG. 1 shows how a helically formed, cylindrical hollow body 3 of a device for
- Vacuum can be generated by means of the line, so that film layers 8 are positioned and fixed to the cutting surfaces 9 of the helical, cylindrical hollow body 3. After the film has been separated by the rotating screw-shaped cylindrical hollow body 3, a medium can then be introduced through the line 6 and via the bore 10 between the film layers 8.
- helically shaped, cylindrical hollow body 3 which can be coupled by means of the shaft end 15 to a drive and on the other hand has the helically shaped end 12, which terminates in the cutting surfaces 14.
- gaseous or liquid media can be performed.
- Fig. 3 it is shown how the helically shaped, cylindrical hollow body 3 is screwed into a bag with two film layers 17 and 18, so that the upper film layer 18 was lifted by the helical thread 16 and separated from the second film layer 17.
