Description

For regulating the device of glue
Technical field
The utility model relates to a kind of device for regulating glue for subsequent applications, and wherein, this device comprises the unit that scatters for glue.
Background technology
This device should particularly by loose distribution, particularly preferably manufactured by wood materials and use during plate of material.Here, the most preferably glue is sprayed in one pack system or multi-component nozzle.
But also gluing is for producing product or all parts of machine element, particularly plane earth veneer(ed) wood or laminate during producing glued board, supporting arrangement, adhesive or the like.
The plate being made up of wood materials is particularly interpreted as timber flitch, particularly fiberboard, such as MDF plate, HDF plate or LDF plate and also USB board etc..When producing these plates, wood chip or analogous wood substance grain is made to carry out gluing, it is generally understood as at this spraying with glue or adhesive, this can relate to isocyanates, Trimeric β peptide, urea-formaldehyde resin, urea formaldehyde resin, melmac, phenolic resin or other resin, such as based on polyamines or tannic acid.
By DE 10 2,013 104 653 A1, DE 10 2,011 077 514 A1 or the DE 10 2,009 006 704 known glue of A1 spray and the method and apparatus of the scattered particle of gluing.By DE 10 2,011 007 336 A1 and DE 10 2,008 059 877 A1 known nozzle, can sprayed glues in said device by this nozzle.
Then, so glued particle is positioned in distribution backing strap, this distribution backing strap the most in a press, in the case of applying pressure and heat, be pressed into the plate of correspondence by wood materials.Forcing press relates to circulating operation type single or multiple lift forcing press or continuously operating press.
In the case of producing this plate, the gluing of fiber has special significance, because the characteristic of the plate produced (such as its transverse strength) is decisively determined by used glue.
When gluing problematic, agglomerate can be formed inside glue, these agglomerates are spreading in backing strap and glue can caused to be mingled with in the plate of compacting subsequently or glue caking.Being mingled with by these glue or glue caking can form the position that point-like is hardened in plate, difficulty can be caused in these positions then when being processed plate or processing.Additionally, this glue agglomerate also can cause the less desirable inhomogeneities on the surface of plate, thus can negatively affect its visual appearance.For manufacturing especially for thin plate, this can cause density to raise during fabrication, and density rising can cause the damage of the pressing plate to forcing press or steel band.
But it is possible to the glued generation connected loaded needs the glue of optimal regulation and it is mainly most preferably positioned on cemented surface (such as when production adhesive).
In order to avoid this problem, it is known that the unit that will scatter is positioned in glue feeding means, they play the effect disconnecting agglomerate corresponding in glue.
Although but it has been shown that have adjusted rotating speed or the power of de-registration apparatus substantially the samely, but via de-registration apparatus guide glue not always have desired denseness and not always can be reproducible realize desired denseness.But this in the industry or is needs in handicraft, to keep reproducible and comparable result, particularly in big commercial Application.It is also expected to the glue floating thing provided has the fluctuation of minimum in terms of its composition or its component.Mixed proportion in glue block also due to the difference of the device, supporting or the transport path that are used and fluctuate, therefore these can cause viscosity fluctuation.
Particularly disadvantageous, viscosity fluctuation can the glue quantity of making a difference by its characteristic.Here, quantitatively deficiency normally results in waste product, and the most excessively can cause the glue of waste costliness.
Utility model content
Therefore task of the present utility model is to develop the device of a kind of aforementioned type further, can continuously ensure that desired glue denseness.Further task is to provide a kind of device for regulating glue, and this device makes it possible to prevent from producing the glue interrupting and providing optimal regulation for the startup optimization produced in time.
Task for this device so solves according to the utility model: be in series with heat exchanger at the glue unit that makes to scatter on the path of adjusting means.
The utility model based on the recognition that by scatter unit agglomerate in pulverizing glue time via shear work, energy is incorporated in glue, thus make glue heating accordingly.
Because the viscosity of glue depends greatly on temperature, thus the viscosity of glue due to this energy introduce and the glue temperature change that associates with this and significantly change.By glue is directed through the heat exchanger (taking out again energy at this from glue) of correspondence according to the utility model, glue can be cooled to again desired temperature, so that glue has desired correct viscosity for being processed further.
But in the case of the utility model, the heat exchanger connected with the unit that scatters is not connected on after the unit that scatters but is connected on before it.In this way, from glue, first take out energy via heat exchanger, and in the unit that scatters, big energy is introduced in glue again subsequently, so that glue has desired temperature and the most desired viscosity when leaving and scattering unit.
Additionally, in the case of the utility model, make glue cool down with being arranged in heat exchanger the most unrelated before the unit that scatters, to disperse energy, or also can heat to feed further energy.It is essential that glue through scattering unit and be positioned at its front of or behind heat exchanger at the end of there is viscosity correct for application.
In the most preferably embodiment of the present utility model, it is provided with the viscosimeter of correspondence, directly determines the viscosity of glue by this viscosimeter.Data owing to learning by viscosimeter are directly used in control or regulate this device, particularly relate to a kind of so-called in-line viscometer at this viscosimeter.
At this it is known that viscosity is a kind of tolerance of the uniformity of glue suspension, i.e. uniformity the most then viscosity generally raises.But at present temperature also has material impact, thus, viscosimeter is also learned temperature, with can be for the measured value provided by viscosimeter to carry out temperature-compensating.
In principle, in further improvement of the utility model, the measurement result of such as viscosimeter or be incorporated into the data of the energy size of glue, the energy size being incorporated in glue via heat exchanger or taking out from glue, temperature or the like via the unit that scatters and be pooled in analytic unit, thus to implement regulation or the control of correspondence.Here, can determine that particularly by unit or the energy size that is incorporated in glue by heat exchanger or disperses of scattering.
Further improvement of the utility model could dictate that buffer is integrated in the transport path of glue.Alternatively or in combination, part or all of glue of be directed over scattering unit and heat exchanger can be transported by single pump at this.
Described pump is the most adjustable at this, so that pump adapts in pending glue quantity and the viscosity of glue Self-variation.
It is preferred that this pump has the pump volume of maximum possible at this, this pump volume is positioned at and should flow through on the volume of adjusting means.Glue thus can be made repeatedly to guide before it delivers to follow-up part of appliance by the device for regulation.
Described buffer particularly can have the advantage that the glue providing correct regulation at the glue nozzle of self when start-up course starts when corresponding device starts, and glue is finally mixed in wood materials by these glue nozzles.Thus, also can reduce the amount of waste product, these waste products originally can when equipment starts or during application, particularly appearance during producing plate of material etc..
Additionally, be the most persistently provided with uniform pressure in buffer, the regulation for the entrance parameter changed thus can be saved in follow-up equipment.
Accompanying drawing explanation
Other advantages and features of the present utility model are given by the following description to embodiment.It is shown in which:
Fig. 1 illustrates the line map of the adjusting means for glue;
Fig. 2 illustrates the line map of the alternate embodiment of the adjusting means for glue.
Detailed description of the invention
In FIG it can be seen that be used for regulating the line map of the device of glue, glue can be used for being manufactured ejecting plate by wood materials.By a kind of glue via one or more feed line 1 or can also be various glue or can also be correspondingly that the corresponding part (about its composition) of glue floating thing is incorporated in adjusting means in some cases.Then this glue first flow through filter 2, and coarse granule is cut in this filter.This filter 2 can be also twinfilter in the way of being not shown here, and thus there is a possibility that and disable a filter in order to safeguard, and another filter individually undertakes filtering completely of the task of glue simultaneously.
By the pump 3 being connected on after filter 2, glue can be directed through the unit 4 that scatters.This pump such as refers to centrifugal worm pump or gear pump.But other pump configuration form is also possible.
Scatter in unit 4 after being connected on pump 3, such as, can disconnect via the rotor rotated and stator component and smash the agglomerate staying in glue.If feed the heterogeneity of glue via feed line 1, then these compositions are also mixed with each other in the unit 4 that scatters.
By the component moved relative to each other of the unit 4 that scatters, due to the shear work done by these components, thus being incorporated in glue by energy, this causes the temperature of glue to raise.
Owing to this temperature rising can cause the significant change of glue viscosity, and this change is relevant with the subsequent applications of glue, so after glue has just been directed over fine filter 5, glue is just directed over heat exchanger 6 herein in unshowned device.Here, remove again energy from glue, so that its temperature and thus make its viscosity reduce.
Before glue is directed in holder 8, unshowned example is connected on herein the glue viscosity measuring gained in heat exchanger 6 viscosimeter 7 below continuously.
The viscosity of glue is an important measure of its uniformity.Uniformity the most then viscosity rises.
Herein, unshowned embodiment relaying resumes and is delivered to analytic unit 9 data determined by viscosimeter 7.Owing to viscosity is also had a major impact by temperature, thus also test constantly temperature level, particularly to carry out temperature-compensating about viscosity measurement when necessary.
In this regard, the data of various pressure sensors (P) and temperature sensor (T) are also fed to analytic unit 9.This analytic unit is provided with following program: can control the power of pump 3 and the rotating speed of the unit 4 that scatters or power via this program, also can control the heat shed from glue at heat exchanger 6.Other corresponding or required control and/or governor motion can be learned, successfully to revise the device for regulating glue or method according to its training and practical experience by technical staff.
It is important in this that, if the viscosity measured at viscosimeter 7 is not up to desired predetermined value, the most also at heat exchanger 6, energy is incorporated in glue.
The glue then with desired denseness can be directed in holder 8, and glue takes out from this holder via pipeline 10, thus is fed to quantitative pipeline that is that be not shown specifically and/or that describe or the bonding device of equipment at this in known mode so far.It is preferred that this equipment that could be for producing particieboard etc..Holder 8 is preferably maintained under constant pressure at this, thinks that follow-up assembly ensures that constant feed conditions.
In device not described herein, pump 3 is preferably regulated so that as circulating pump its upwards of movement is slightly above via the glue volume of feed line 1 feeding.It is positioned at the glue in holder 8 by taking out via branch line 11 and makes it mix with the glue from feed line 1, produced difference can be made up.Here, can ensure that first the glue arrived before holder 8 from feed line 1 at glue be directed through scatter unit 4 and heat exchanger 6 from pump 3 via check-valves 12.
This connected mode particularly avoids regulation unit described here and is in idling conditions.Thus can avoid the adjustment of costliness, this adjustment is required for being transferred again into process the most to be controlled from this idle cycle.Idle running can be avoided by the corresponding programming of analytic unit 9 and the particularly liquid level gauge in holder 8.
Additionally can ensure that and the glue at least experiencing Primary regulation section is fed to follow-up part of appliance.In principle, the pump 3 as circulating pump work is also adjusted to than bulky transport volume required in follow-up part of appliance.Thus, the glue being positioned in holder the most also can Multiple through then out adjusting means described here.
Figure 2 illustrates another design of the adjusting means for glue.This design corresponds essentially to the embodiment explained by Fig. 1, thus, identical parts are provided with identical reference.
In embodiment shown in figure 2, here, be additionally provided with another heat exchanger 13 between filter 2 and pump 3.The glue temperature adjustment in advance from feed line 1 feeding can be made, so that glue is most preferably transported by pump 3 and can be processed in the unit 4 that scatters subsequently by this another heat exchanger.Here, via this heat exchanger 13, energy can be incorporated in this glue stream, it is also possible to take out energy from this glue stream.
In principle, heat exchanger 6 also can be only deemed as optionally the most in such an embodiment, to realize the calibration more refined to the temperature of glue and thus viscosity by it when necessary.
Additionally, in fig. 2 it is also seen that reversal valve 14, this reversal valve 14 is integrated in the pipeline after viscosimeter 7.Can be conducted directly to the glue being adjusted via this reversal valve 14 to go in the pipeline 10 of quantitative pipeline, and not be used in holder 8 buffering glue.This is the most meaningful in the case of must being cleaned when holder is in operating.
It is preferred that fine filter 5 is also embodied as self-cleaning filter, this self-cleaning filter mechanically wipes across filter with the interval provided in advance.Here, the thick part wiped is directed to again to scatter before unit or be conducted directly to scatter in unit, with these parts of again scattering.
Device described here particularly has the advantage that by this device, glue required during manufacturing plate of material etc. the most accurately and mainly is conditioned the most continuously, even and if being thus directed towards producing when startup optimization and be also provided that the quality that holding is constant.
