Description

Apparatus and method for applying flowable components

description

The present invention relates to a method for continuously applying at least two flowable components on a horizontally moving substrate, in which the components in the form of strands and / or dots is applied, wherein the number of the component strands and / or points and / or the position the component strands and / or points on the substrate during application is verän- derbar. Furthermore, the invention relates to a device for performing the method with a conveyor for the substrate and at least one coating portal, are connected to the supply lines for the components, wherein the coating portal comprises at least one discharge for each component, and wherein the discharge device comprises closable nozzle, that may be opened by a common drive and seal.

The application of one or more fluid components with the aid of nozzle systems from, for example, a plurality of serially arranged nozzles is extensively described in the prior art.

The application of hot melt adhesive as the sole flowable component to a substrate, for example wood veneer is described in US-A 4,420,510. The hot melt adhesive is applied over a number of nozzles. The task was to obtain uniform application in the running direction of the substrate. The nozzles can not be controlled individually located. Therefore less excess of melt adhesive is made depending on the substrate width increasing or that must be laboriously collected and recycled. In addition, there is a danger that the side edges of the substrate are contaminated by flowing past melt adhesive.

In DE-A 34 35 286 the spraying of hot melt adhesive is disclosed in insulating glass. The hot melt adhesive serves as a spacer and is later removed from two or three nozzle melt adhesive is mainly applied close to the edge on the glass plate. The nozzles cover a small area and can not be controlled individually. In US-A 4,157,149 is generally the application of a single component, di-melt adhesive disclosed above nozzles arranged in parallel. These can be controlled together or individually by means of an elaborate control. The dimensions of the device in general and of the nozzle in particular are not specified.

The focus of the timber is separate application of several components, such as a resin and hardener components, onto a moving substrate. In a separate application of the components they come only at the application to the substrate, on the substrate or advantageously only in further processing, such as the pressing together of the substrates in contact, allowing to elapse a longer time span between application and pressing, can without during this period curing undesirable extent occurs. The time period is called open time or assembly or processing time.

The following documents from the prior art describes a sequential up-take of the resin and hardener components in the form of strands using various applicators:

For example, DE-A 37 12 347 an apparatus for applying glue to be glued wood parts, with a feeding device for the wood parts, an upper half of the feed path arranged and transversely thereto extending hollow body, which on its side facing the feed direction side of one or more having rows of outlet openings in the form of holes or slits, and is connected to a reservoir for the glue, and a pump. For applying a hardener, a second applicator, which is the same as for the glue, is angeord- net. In DE-A 37 12 347 below the feed path in the amount of glue or hardener-discharging hollow body is described that it is advantageous to provide a collection container for the surplus glue, which is connected via a return line and a pump connected to the reservoir.

EP-A 860 251 describes a device for applying a multi-component system that includes a provided with outlet pipes first hollow body and a second hollow body which is provided with at least as many outlet apertures as there are outlet pipes in the first hollow body, wherein the outlet ports the second hollow body, the openings of the outlet pipes of the first hollow body kreisför- mig surrounded.

EP-A 1089827 discloses an apparatus for applying a glue-hardener system of at least two components, which device consists of a unit of at least two high components, according to a component for a component. Each construction part is provided with a number of openings so that the respective components are applied to a moving substrate below the hollow members in the form of strands.

EP-A 1,426,114 describes the application of glue and hardener on a substrate with the help of two series-connected rows of nozzles. The nozzles can not be controlled individually located. It falls depends on the width of the substrate is always a smaller or greater excess of components which must be laboriously collected and zurückge- leads. The side edges of the substrate can be contaminated by flowing past components.

The shown in the prior art devices solve the problem of premature undesirable curing. Furthermore, the substrates can be coated surface.

However, the wood processing plants demand besides the features that the device is to work very quickly for applying flowable components and operate, maintain with minimal effort and should be cleaned, that the device may be further adapted to uneven wide substrates so that neither Verleimungskomponenten can reach over the edge of the substrates, nor too wide distance from the edge remains uncoated.

To those described in the prior art methods and devices it is not possible to quickly moving substrates whose width changes to coat so that none of the fluid component passes over the edge of the substrates or not produced too large uncoated margin. A varying width can not be effected in the perpendicular Beleimungsanlage mono- guided substrates by non-uniform widths of the substrates, or by.

By then devoted uneven application of both the substrates and the device be contaminated for coating. For this reason, these devices need to be cleaned periodically at great expense.

Another disadvantage of the nozzle systems of the prior art is also the fact that the nozzles are also open at a production standstill and thus tend by dust or curing of the gluing system clogging.

The object of the present invention was therefore to provide a process and an apparatus for applying at least two flowable components, a spatially delimited coating of fast moving substrates allows varying width, without losing significant amount of the fluid components over the edge of the substrates or to obtain uncoated edge pieces. In departures from should the application of the components at the beginning, that is to stop or on the top substrate, and at the end of production, for example at the substrate end, begin suddenly and precisely. Furthermore, the applicator should be easy to clean and waiting.

Accordingly, the process defined at the outset. The term "strand" also includes the meaning of the other terms used in this art "Band", "stripes" or "string" and any other similar term.

Advantageously, two or more flowable components in the form of parallel strands or points, in particular strands applied. The strands or dots can be applied individually and independently, optionally selectively. two or more components are particularly preferably alternately, in particular in parallel strings, applied to the substrate.

The number of components strands and / or component points is expediently adjusted to the width of the substrate and the position of the substrate. The number of components strands and / or component points can advantageously between 10 and 100 per component per substrate width, in particular between 30 to 70 varies. The width of the substrates is generally from 50 to 400 mm, advantageously 150 to 300 mm.

The strands or points of the individual components may overlap, depending on the respective reactivity partially or completely or OH overlap spatially separated ne be applied, for example, in the earlier German Patent Application with the application number 102004015736.7.

The components can be temporally and / or spatially simultaneously or temporally and / or spatially offset from each other to be applied. In a staggered order-the order of the respective order of the components depending on the substrate can rabreitung the particular components used, the subsequent VE and are selected the desired essential properties of the final product.

Aminoplast resins are preferably used, in particular melamine-urea-formaldehyde resins, etherified melamine-formaldehyde resins, urea-formaldehyde resins or mixtures thereof. Melamine-urea-formaldehyde resins and / or etherified melamine-formaldehyde resins are particularly preferred, wherein the content of etherified component is advantageously> 50%, in particular> 75% in a mixture. The degree of etherification is advantageously from 1 to 95%, preferably 15 to 80, in particular 30 to 65%.

The inventive method is not limited to a particular application, however, it is advantageously used in the timber industry. The process is preferably to separately contract for gluing wood, for example in non-structural applications such as parquet, Rollenheißkaschierungen used (slides, for example, particle board), veneers, plywood, single-layered, multi-layered panels, shuttering boards. Further, the method is advantageously used in load bearing applications, such as in glue-laminated wood, duo or trio beams (see also WO 02/068178 or EP-A 860 251). Furthermore, the invention relates to a device for performing the method according to the invention. The inventive apparatus is defined at the outset.

The common drive may be pneumatic, electro-magnetically, mechanically or hydraulically controlled.

The apparatus advantageously comprises at least two portals coating with a respective discharge device. Optionally, a coating portal may also have multiple discharge devices.

The discharge device (s) is / are advantageously constructed from a number of individual nozzles and / or valves. Advantageously, the discharge devices have individual nozzles 10 to 100, preferably 30 to 70 jets on.

The individual nozzles of a discharge are advantageously at a distance of 3 mm to 15 mm, preferably from 4 to 12 mm, arranged in particular from 5 to 9 mm. The nozzles are suitably arranged in series. If necessary, several rows may be arranged one behind the other, which are arranged in a staggered or directly behind one another. wherein the nozzles of the second row are advantageously arranged with a gap to the first row, two rows are preferably used. The distance between the two rows should be as small as possible, advantageously less than 20 mm, preferably less than 15 mm.

The discharge device is expediently powered by a pressurized circulation circuit with the free-flowing components, wherein the discharge device is connected via supply lines to a reservoir components. The pressure of the required flow rate of the fluid component is appropriately adjusted. The discharge device may for instance be designed as a flow tube with a flow cross-section of 200 to 3000 mm 2.

The discharge means advantageously have nozzles which open through the sealing plunger and can be closed again.

Advantageously, the plunger seals the nozzle from the fact that it is precisely manufactured to diameter nozzle and completely immersed in the nozzle during the closing present. Optionally, the plunger may extend for closure of the nozzle by a few millimeters, advantageously the plunger protrudes not more than 3 mm from the nozzle. Preferably, the plunger protrudes 0.5 to 1 mm from the nozzle. The diameter of the nozzle and the plunger are accordingly designed so that no flowable component through the remaining gap can flow. The general manufacturing of a precisely fitting plunger is known to those skilled in the art of mechanical engineering. The stroke of the ram is advantageously 2 to 15 mm, preferably at 4 to 10 mm. The opening force is advantageously at 30 to 150 N, preferably 50 to 100 N.

The nozzle diameter is advantageously from 0.5 to 5 mm, preferably 1 to 3 mm, especially 1, 6 to 2 mm.

The ratio of nozzle diameter to nozzle length is advantageously from 0.2: 1 to 3: 1, preferably 0.5: 1 to 2: 1.

The plunger-nozzle system can advantageously be designed in the form of a plug seal, in the form of a ball or plug seal in the form of a cylinder gap seal. Preferably, the plunger-nozzle system is designed as a cylinder gap seal.

individual nozzles selectively and independently from each other to open and close are advantageous.

the nozzles are closed depending on the width of the substrate or opened advantageous or remain in the open state. Advantageously, a Randbe- to the substrate of more than 10 mm and not remain rich unbeleimt flowable component or only insignificant amounts in addition to or in front of or behind the substrate are metered.

To ensure this, for example at not perpendicular introduced substrates or unevenly shaped substrates, the application device is a measuring system, upstream, for example, with an optical sensor that detects the width and position of the substrates to which the components are to be applied. This measurement system sends a signal to the application system. Suitable optical systems are generally known. Particularly suitable are so-called light barrier, consisting of an optical / electronic system, comprising a light source (transmitter) and a receiver (sensor) exist. The optical signal from visible, infrared and / or ultraviolet light will be polychromatic or monochromatic, for example in the form of laser light emitted and recorded by an optical sensor. This can be done one way or reflection. If the optical path affected by the substrate, for example by interruption, this is registered by the optical system.

There is produced a signal which is optionally converted. This is sent to the application system. The order system on the nozzles of the application apparatus according to, ie, the nozzles are opened or closed. Suitable systems are, for example, individual light barriers. Particularly suitable systems are curtains of light barriers and laser scanners. of preferably arranged in a row nozzles on one or both sides can advantageously also hold one or more nozzles permanently closed in the edge region. Consequently, the width of the contract to the width of the substrates can be adjusted. The drive is advantageously designed so that for example, the plunger driven in the order from outside to inside, and thus the nozzle are sealed from the outside inwards, that is, the nozzles are arranged to the substrate edges toward be sealed to first and last nozzles which are arranged to the substrate center. the nozzles are opened advantageous from the inside to the outside.

This opening and closing requirements can be accomplished for example by means of a combination of two drives. The first drive advantageously serves the nozzles in the beginning pass through a substrate abruptly simultaneously and precisely to open, and after passing through the substrate as well abruptly simultaneously and accurately to close. the first drive is preferably operated pneumatically. The second drive is designed so that the second drive overrides the closure of one or more individual nozzles may cause the state of the first drive. Consequently, all the nozzles must be closed on two drives, of which the first actuator to the nozzle total acts and the second drive the closure of one or more nozzles effected.

This opening and closing requirements can preferably be accomplished by means of a single drive. This drive is preferably operated pneumatically. Consequently, the nozzle can be opened by a pneumatic drive or close to comparable, wherein the opening or closing is limited by a piston-cylinder unit has a number of nozzles. The number of nozzles is advantageously determined by the width of the substrate.

For closing of the nozzle, the plunger are advantageously immersed at a comparable speed in the nozzle with which the component / liquid flows through the nozzle.

The plungers are advantageously momentarily to rest when they reach the forward end of the nozzle. If necessary, the plunger can also easily jump back.

The free ends of the plunger may optionally have a flat tip. Preferably, the free ends of the ram are cone-shaped with a cone angle of at least 120 degrees.

Advantageously, the nozzles are made of a material which is wetted by any of the components to be applied, that is, the nozzles consist of a with respect to the fluid component anti-adhesive material. Preferably is suitable as a nozzle material is polytetrafluoroethylene, polypropylene, polyethylene, polyvinyl chloride, polyamide, polystyrene, polycarbonate, polyacetal or polyoxymethylene or coatings of the aforementioned materials.

Optionally, the nozzles are arranged on a separate, removable disk independently from the rest of the circulation circuit, so that they are easy to replace in case of wear.

the free ends of the plunger from a dewetting, antiad- häsiven material, such as polytetrafluoroethylene, polypropylene, polyethylene, polyvinyl chloride, polyamide, polystyrene, polycarbonate, polyacetal or polyoxymethylene or coatings of these materials are advantageously prepared.

As material for the plunger usually materials come into consideration which are wetted by any of the components to be applied, for example, polytetrafluoroethylene, polypropylene, polyethylene, polyvinyl chloride, polyamide, polystyrene, polycarbonate, polyacetal, or polyoxymethylene.

for protection against wear on the one hand is advantageous for the supply container in the interior cavities of the application system and the nozzle inner surface coated with a wear resistant material. As a wear-resistant material, in particular stainless steel is suitable in the form of a thin sheet or in the form of Einpresshohlnieten.

Optionally one may surround the nozzle with annular air nozzle to blow off synchronously to switch-off the components on the plunger.

Further, the plunger can also be designed as hollow needles if necessary. Through the hole compressed air can be passed, the accelerated especially during switching-off the tearing of the liquid strand.

Furthermore, if appropriate, in the vicinity of the plunger heat sources such as heating elements are installed so that the components evaporate in a short time at this point.

The feeding means is located below the coating portal is further advantageously equipped with a locking system, so that the substrates pass through flush on one side of the coating site and the distance between the substrate and discharge remains constant. This distance is suitably from 5 to 100 mm, advantageously 5 to 50 mm, preferably 10 to 30 mm.

For example, in a two-component system, the two coating portals to each other transversely to the substrate direction by half a nozzle pitch, ie, about 1, 5 to 7.5 mm, may be arranged displaced laterally, so that the two components on the substrate respectively on gap be applied.

The coating portals can be oriented advantageously by means of a means for positioning ren.

Using a plurality of components, these are advantageously spatially plotted separately from each other, wherein the distance of the coating portals should be as small as possible in the direction of the passing substrate, preferably less than 50 cm, in particular smaller than 10 cm.

Overnight and downtime all nozzles are advantageously closed by the rams and further the nozzle tappet system is advantageously sealed from the outside air in order to minimize drying out of the liquid components.

Particularly advantageous over the prior art, combined sealing according to the invention and purification process affects. Because the jets closed not only by the ram, but also be purified by this, the daily cleaning can be reduced to a minimum. Further, by the precise application of glue as a curing agent both can also be saved.
