Definitions

  • the invention relates to a device for applying raised structures made of plastic material to surfaces.
  • raised structures are, for example, knobs on handles of sports equipment or tools, for example tennis rackets and hammer handles.
  • the raised structures can also be nub-shaped elevations on pens.
  • EP 523 589 A1 discloses a method for applying adhesive spots on a surface, in which a hollow body with a central distributor chamber is used. Adhesive is fed to this chamber under pressure via a feed channel. The adhesive is dispensed via dispensing channels that open with nozzles in the outside of the hollow body. The nozzles are opened and closed at predetermined time intervals in order to achieve a controlled adhesive leakage.
  • a similar device is known from DE 38 25 972 A1. The outlet nozzles are equipped with dispensing needles.
  • the object of the invention is to propose a device of the type mentioned at the outset which, despite its simple construction, enables the production of uniform raised structures made of plastic material on surfaces.
  • a filler is arranged in the distributor chamber, the peripheral surface of which, with the inner wall of the distributor chamber, delimits a gap space connecting the channels to one another.
  • the plastic material is selected so that it solidifies after application.
  • the filler arranged in the distribution chamber prevents the plastic material from reaching the closest delivery channels in a straight line, so that these delivery channels a larger amount of plastic emerges than from the more distant discharge channels. Due to the fact that the feed channel and the discharge channels are arranged on opposite sides of the hollow body, a structure of the hollow body and the filling body arranged therein which is symmetrical with respect to the longitudinal axis of the feed channel can be achieved.
  • the hollow body is designed in the manner of a tube section closed at both end sides, the discharge channels being arranged in at least one row extending in the longitudinal direction of the hollow body and the feed channel being positioned centrally with respect to the row longitudinal direction.
  • elongated objects for example pens
  • the feed channel being positioned centrally with respect to the row longitudinal direction.
  • elongated objects for example pens
  • the discharge channels, or their mouth openings which are expediently designed in the form of nozzles, can have different cross-sectional shapes and can be round or oblong, for example.
  • the height of the knobs produced depends on various parameters, for example on the viscosity of the plastic material used, the amount of plastic dispensed in each case from a dispensing channel and also on the distance between the outlet opening of the dispensing channels and the surface.
  • thermoplastic materials for example in the manner of hot glue or the like, is possible if heating channels are arranged in a wall surrounding the distribution chamber, which can be heated with electrical resistance wires or with hot liquids.
  • FIG. 1 shows a device according to the invention with a filling body arranged in the distribution chamber in a cross-sectional view
  • FIG. 2 shows a section along the line II-II in FIG. 1
  • FIG. 3 shows a further embodiment of a device in a view corresponding to FIG. 1
  • FIG. 8 shows a heatable device in a view corresponding to FIG. 2
  • FIG. 9 shows an embodiment of a device in longitudinal section
  • FIG. 10 shows a plan view in the direction of arrow X in FIG. 9.
  • FIG. 1 and 2 show the basic design of a device which, like all the other exemplary embodiments, comprises an elongated, approximately tubular section-shaped hollow body 1, in which a distributor chamber 2 is arranged centrally and extending in the longitudinal direction thereof.
  • the wall 3 of the hollow body is penetrated on one side by a feed channel 4 and on the opposite side by a plurality of discharge channels 5.
  • the delivery channels 5, which are preferably arranged in a row extending in the longitudinal direction 17 of the hollow body 1, are formed by tubes 6 which project from the application side 7 of the hollow body 1 facing away from the feed channel 4, essentially at right angles.
  • the device works approximately as follows: the feed channel 4 is connected to a suitable charging device and the distribution chamber 2 is charged with flowable plastic material, for example with an air-drying polymer dispersion.
  • the plastic material is distributed approximately according to the arrows 8 and emerges from the delivery channels 5, as indicated by the arrow 9.
  • the height and surface area of the knobs produced on a surface or generally of raised structures depends not only on the amount of plastic material conveyed by the loading device but also on the shape and size of the outlet openings 5a of the discharge channels 5. Another factor influencing the size and height of the knobs is the distance between the outlet opening 5a of the delivery channels 5 and the surface. If the distance is large, relatively small and high nubs are formed. At a closer distance, the knobs become flatter and wider, which is probably due to the fact that at a closer distance the plastic mass has less time to harden, so that when it hits the surface it is still flowable and can flatten and spread on the surface.
  • FIG 3 shows an exemplary embodiment in which a packing 10 is arranged in the distributor chamber 2.
  • the filler body 10 extends between the end walls 11 of the hollow body 1 that laterally delimit the distributor chamber 2.
  • the filler body also has a cross-sectional shape corresponding to the inner cross section of the distributor chamber (see, for example, FIGS. 2 and 4).
  • the filler 10 ensures a more uniform distribution of the plastic material on the discharge channels 5 arranged in the longitudinal row. This essentially prevents a larger quantity from the discharge channels directly opposite the feed channel 4 than from the discharge channels adjoining it laterally. An even distribution can be achieved if the packing, starting from its center, tapers conically towards its ends.
  • the internal cross-sectional shape of the distributor chamber 2 and the corresponding cross-sectional shape of the filling body 10 are almost arbitrary and can be, for example, circular, triangular or hexagonal (FIGS. 4 to 7).
  • heating channels 21 are arranged in the wall, which extend in the longitudinal direction 17. Electrical resistance heating wires can be arranged in the heating channels 21. However, it is also conceivable that a heating medium flows through the heating channels 21. With such a device it is possible to use thermoplastics for the production of raised structures on surfaces. The plastics are in the Melting feeder, fed to the distribution chamber 2 and kept there in a flowable state due to the heatability of the distribution chamber.
  • the filler body is fixed interchangeably in the hollow body.
  • the filler body has, on its two end faces, blind-hole-shaped recesses with an internal thread 13, into which a screw 14 is screwed with its threaded shaft 15.
  • the screw 14 passes through an end opening 16 in the end wall 11 of the hollow body 1 and is supported with its screw head on the end side of a pipe section-shaped connection piece 18 projecting from the end wall 11 essentially at right angles or in the longitudinal direction 17.
  • a spacer sleeve 19 having a radial flange 20 is inserted between the socket 18 and the screw shaft.
  • the radial flange 20 is arranged between the screw head and the front end of the socket.
  • On one side of the hollow body 1 there is a bore forming the feed channel 4. From the opposite side of the order 7, the delivery channels 5 or the tubes 6 protrude in two parallel rows extending in the longitudinal direction 17.
