Description

Device for continuously producing glued laminated board

Technical field

The utility model is related to a kind of device for being used to continuously produce glued laminated board.

Background technology

The abbreviation LVL (laminated veneer lumber) that glued laminated board or clamping plate are interpreted as example introducing in the whole world by technical staff Or glued board (glued board).Here, the glued board used generally has 0.5 to 6 millimeters of thickness.For special application Field, also can widely combine various materials or other products, such as plastics, metal packing and film.

Each glued board of different quality and size is separated before actual lay and pressing process, and according to certainly The requirement of the lay pattern of dynamicization laying apparatus is transmitted.

Cementing layer bar is interpreted as the row's plate group or continuous lath of the glued board stacked, and this is formed in station is laid Plant cementing layer bar.Glued laminated board or glued laminated board bar are interpreted as leaving the cementing layer bar of forcing press after pressing.Therefore, it It is related to the final products or intermediate products that can be then for further processing.

Method and dress for cementing layer bar that large area glued board is automatically laid to layered group or layering on a large scale Put first public in the A1 of DE 196 27 024.The task of this method is：Automatically by plywood parquet (or the glue of large area Close film) layer group is continuously merged into enough mechanical link things.When all manufactures or manufacturing parameter are optimally coordinated with each other simultaneously And equipment is when also correspondingly working, glued laminated board can be produced with good quality by this method.

It has been found that particularly when production is with the thin glued laminated board for being less than 10 mm of thickness, due to glue to be pressed The thickness of conjunction layer bar is smaller and can cause to continuously operating press, particularly cause to damage at its steel band, cementing layer bar It is pulled through and is pressed at steel band.For example by undesirably contacting the density in upper steel band and lower steel band or cementing layer bar Rise.Additionally it has been shown that the thickness and precision of repressed cementing layer bar declines, this can cause waste product to increase.

In addition, in the known devices of prior art, the speed of forcing press can be passed through for cementing layer bar by laying station composition The restrictive factor of degree.For thicker glued laminated board, the ratio between the depositing speeds of glued bar and the pace of glued bar What example may be matched still, because thicker glued bar needs longer residence time to be hardened in a press.But When producing relatively thin glued laminated board, due to its less thickness and thus relatively rapid hardening of related adhesive, these are relatively thin Glued laminated board forcing press can be advanced through with higher pace so that lay station form sky in process of production Lack.

Utility model content

Task of the present utility model is to provide a kind of device, and the device eliminates disadvantages mentioned above and caused particularly thin The production of glued laminated board be reliable and low price.

It is for the settling mode of the task of device, is disposed with before continuously operating press for will at least two The station that individual cementing layer bar is combined.

By merging at least two cementing layer bars before pressing, thicker material strips can be pulled through forcing press, thus It is avoided that the damage to steel band.Due to suppressing thicker bar by stacking cementing layer bar before continuously operating press, The thickness change of glued laminated board can additionally be improved, and realize the more preferable thickness and precision of glued laminated board.In addition, in forcing press Cementing layer bar is stacked before eliminates the defect for laying the vacancy that station causes whole equipment.Thicker stacking is with less speed Forcing press is pulled through, the hardening to two cementing layer bars thus can be completely carried out.Thus, equally with identical, it is less before Enter speed to form cementing layer bar, the pace is enough for forming the cementing layer bar of high-quality.Although stacking Residence time in a press is more slightly longer for simple cementing layer bar；But stack multiple cementing layer bars and simultaneously Carrying out compacting totally can cause productivity to be obviously improved.

It is preferred that being disposed with for introducing separating medium between cementing layer bar, at cementing layer bar, particularly introducing The separating medium station of film or paper.Separating medium station can be for example the device with a roll of separating medium.Alternatively, in pressure Another device for rolling used separating medium after pressing can be disposed with after machine.

Another embodiment, which defines glued laminated board, has the thickness for being less than 10 millimeters, being preferably 3-9 millimeters.

Discontinuously or it is continuously formed cementing layer bar in an advantageous manner.

Alternatively or in combination, be disposed with transverse to production mode reform after forcing press for by the stacking suppressed or The distribution apparatus of person's cementing layer lath customized cut-off.

Preferably embodiment is characterised by, separator is disposed with before or after distribution apparatus, by heap It is folded to be divided into each glued laminated board or stacking is divided into cementing layer lath.

It is characterised by by the method for aforementioned means, forms at least one second cementing layer bar, and at least two glue Close layer bar to be put together before pressing, and stacking is jointly pressed into continuously operating press.With favourable Mode, formed cementing layer bar stacking when, introduce separating medium, particularly film or paper between each cementing layer bar.It is logical Cross introducing separating medium and may insure that being stacked on for cementing layer bar is pressed into after the stacking of glued laminated board and can be dispersed into again Each glued laminated board.It is possible thereby to be effectively prevented from for example connecting due to the glue of outflow or bond each cementing layer bar. Separating medium (particularly when it is paper or film) equally can be rolled-up and reuse again.Alternatively, it would however also be possible to employ The separation media strips of Infinite Cyclic.It is preferred that between two cementing layer bars or the contact between cementing layer bar and separating medium Face does not have binding agent.Alternatively or in combination, it is stacked on to be pressed into after glued laminated board or cementing layer lath and is separated.Take Certainly in subsequent applications, meaningfully：Each cementing layer lath is separated first, so that they are for example continuously provided with coating. It is same to be contemplated that：The stacking of continuous glued laminated board is firstly split into each stacked group, and when they enter with for example having no problem Glued laminated board can be scattered from stacked group when row is quenched.It is preferred that at least two cementing layer bars are before pressing in each face side Place is brought together.Particularly, cementing layer bar is merged into over each other.The thickness of stacking to be pressed should be improved, to avoid pair Continuously operating press causes to damage.Cementing layer bar preferably discontinuously or can be continuously formed.For continuous glue Close for layer bar, glued board abuts against each other to lay with not having space.For discontinuously forming cementing layer bar, each glued board Group is so that small spacing is laid as far as possible relative to each other.In preferably embodiment, the cementing layer in continuous cementing layer bar Successively skew, which is turned up the soil, is laid.The stability for causing glued laminated board by skew is improved, because edge will not overlap each other.Compared with Goodly, downtrodden stacking and/or cementing layer lath are always distributed transverse to producer by least one distribution apparatus.Substitute Ground or in combination, cementing layer bar is formed in one or more lay stations.Using it is multiple lay stations be preferably, because Thus it is overall to improve speed of production and therefore significantly improve throughput.
