Definitions

  • the present invention relates to a glue feed unit which can be used, in particular, for machines which process wooden panels.
  • edge banding machines which will be indicated as examples of use of the present invention, without limiting the scope of application of the invention, are so-called edge banding machines. These machines apply a band of material, usually synthetic, by gluing to the edge of the panel with profiles which may even not be straight.
  • pass machines that is to say, linear edge banding machines for the application of edging bands on the edges of panels, in which the panel is fed forward relative to the -edge banding device, which is fixed: in these cases, the glue may be applied both on the edging band and, preferably, on the panel.
  • machines which generally comprise a work table on which a panel to be edge banded is placed and band application means.
  • the work table and band application means move relative to one another to apply the band to the entire edge of the panel by gluing.
  • band application units in which the band application means consist of a unit with a vertical, motor-powered main shaft, supporting and driving a roller which makes contact with the edge of the panel, turning freely about its vertical axis which coincides with the main shaft.
  • glue feed means On opposite sides of the contact roller there are glue feed means and there is at least one main band presser roller, in turn attached to the main shaft and able, in some solutions, to turn relative to the shaft according to the shape of the panel profile.
  • the means which supply and distribute the glue, normally of the "Hot-melt” and polyurethane type, on the edge of the panel or on the band (of particular interest in the present invention) comprise a tank for the glue, which is kept in the liquid state at a predetermined temperature by special heating means, and which can be fed to a distribution unit which may consist of a spatula element for contact with the edge of the panel.
  • the most common architecture for the structure which feeds glue to the distributor consists of the glue tank which is separate (in the sense that it is often physically distant) from the distributor means, and means (normally of the pump type) for feeding the glue from the tank to the distributor.
  • This architecture is not very practical and is difficult to manage, particularly on high productivity machines.
  • polyurethane glue Preferred to other types of glue, because it is, in practice, more resistant to high temperatures and water
  • the aim of the present invention is, therefore, to provide a glue distributor unit for machines which process wood, structured in such a way that it optimises the use of polyurethane glue in cylindrical containers, and with an extremely rational construction architecture, compact but with an operating capacity better suited to the high productivity requirements of current machines.
  • a glue feed unit which can be used on machines which process wooden panels, comprising means for distributing glue on the edges of panels or on bands to be applied to the edges of panels and located close to a working zone and means for feeding glue to the glue distribution means through a connecting channel.
  • feed means are located on a support element and comprise at least a reversible airtight retaining body for a glue cartridge, with a lower opening for connection to the connecting channel and with pusher means acting upon the cartridge and designed to allow glue feed, when activated, into the connecting channel and towards the distribution means.
  • a glue feed unit as disclosed herein may be used, in particular, for machines which process wooden panels.
  • These machines may also comprise means 1 for distributing glue on the edges of panels or on bands to be applied to the edges of panels, the means 1 being located close to a working zone.
  • the means 1 are connected to means 2 which feed the glue through a connecting channel 3, normally under pressure.
  • the feed means 2 are positioned on a support element 4 and basically comprise: at least one reversible retaining body 5 for a glue cartridge 6, and pusher means 8 which act on the cartridge 6, designed to allow the glue to be fed, when activated, into the connecting channel 3 and towards the distribution means 1.
  • the retaining body 5 consists of an airtight cylindrical body, in which the cartridge 6 is housed and sealed by an upper element 16 which forms a cap.
  • the opposite end of the body 5, attached to the support element 4, has a lower opening 7 for connection to the connecting channel 3.
  • the feed and distribution unit support element 4 comprises glue distribution means 1 (not described in detail here because they are not part of the present invention) and at least two retaining bodies 5, 5a, set side-by-side, and independent of one another, so that, when activated, glue continues to be fed to the distribution means 1 when one of the cartridges 6 runs out of glue.
  • the above-mentioned pusher means 8 may comprise, by way of example, a compressed air supply unit 9 acting in the cartridge 6 seat 10 in the retaining body 5, at the top end of the retaining body 5, allowing glue to flow towards the connecting opening 7.
  • the glue is fed to the connecting channel 3 by pushing from the top downwards (see arrow F in Figure 3).
  • valve means 22 which control the glue outfeed, mobile (see arrow F1 in Figure 3), when activated, from a stable position in which the lower opening 7 of the retaining body 5 is closed (see Figure 3), to a position which allows glue to pass through the lower opening 7 towards the connecting channel 3 when the pusher means 8 are activated, and vice versa.
  • the numeral 11 denotes the heating means fitted on the retaining body 5. These heating means 11 are positioned on the retaining body 5 to allow the generation of a temperature inside the retaining body 5 which achieves and/or maintains a glue liquid state in the cartridge 6.
  • the heating means 11 may comprise, by way of example, a plurality of heating elements 12 extending in the retaining body 5, along its entire length and close to the zone at which the body 5 is connected to the support 4, at the site of the connecting channel 3.
  • the retaining body 5 is equipped with means 13 which detect the glue level in the cartridge 6, which are connected to means 14 for controlling and adjusting the glue feed (a known machine control unit, simply illustrated as a block here) to activate or stop glue outfeed depending on the level in the cartridge 6.
  • means 13 which detect the glue level in the cartridge 6, which are connected to means 14 for controlling and adjusting the glue feed (a known machine control unit, simply illustrated as a block here) to activate or stop glue outfeed depending on the level in the cartridge 6.
  • the detector means 13 may comprise a cylinder 15 attached to the top end of the retaining body 5, that is to say, on the retaining body 5 upper sealing element 16.
  • This cylinder 15 has a rod 17, passing through the sealing element 16, and resting on the top end of the cartridge 6, sliding with the latter so as to follow the top end of the cartridge 6 as it is lowered (see arrow F2).
  • the rod 17 is connected to at least one pair of sensors 18 and 19 attached to the cylinder 15 and at different heights so that they detect the lowering of the rod 17 and send a signal to the control means 14.
  • the use of two sensors 18, 19 for each rod 17 means that, when a first rod 17 passes its upper sensor 18, it switches on the heating in the other retaining body 5a, so that, when the cartridge 6 in the body 5 runs out of glue (the second, lower sensor 19 is passed) glue can immediately be fed from the cartridge 6 in the second body 5a.
  • the cooling means 20 may comprise, again by way of example, a plurality of longitudinal channels 21 for the passage of air from the outside to the inside (forming heat exchangers) on the upper sealing element 16.
  • a feed unit structured in this way therefore, fulfils the preset aims thanks to the use of modular retaining bodies for glue in cartridges, which can be used to optimise glue feed to the distributor through a rational, simple and compact architecture.
