Description
Invention relates to the method for the moving extruded stock pad of cutting connection reforwarding in the production line with press manufactured materials plate, belongs to the technical field of claim 1 preamble.The present invention relates in addition the segmenting device for continuous motion extruded stock pad, belong to the technical field of claim 9 preamble.
Consider flitch to be worth doing and be all the production technology of current automation and in many countries, applied for many years by for example intermediate density fiber manufactured materials plate.As by Hansgert Soine ', " composite wood is manufactured and processing " that 1995DRW-publishes, 17ff is described for page, exists that not to be beat be exactly continuously the bits material of preparation or fiber material to be made to the device (press) pushing.Wherein except the front of external this press of many element of installation with after by distributor, manufacture extruded stock pad and also play the part of an outstanding role, and the quality of the extruded stock pad of manufacturing is like this also a key factor except raw-material quality.
In large industrialization, manufacture the press that starts to apply continuous operation in composite timber board situation.In this class press, as described in DE3913991C2, extruding force by hydraulic actuating mechanism be transferred to stripper plate and heating plate and further by steel band-its by a roll body row array (Roller Shaft) by around supportedly configuring-be transferred on this extruded product.In alleged transfer element, this steel band has approximately 1, and the thickness of 5-4mm has in the dangerous machine element chain that lost efficacy and forms the most weak structural member relative other obvious harder elements at this.In this relation and do not mean that, steel band is entirely ineffective.If there has been damage on the surface of steel band, this has just caused the defective surface quality of end product and has therefore become waste product.Owing to producing composite timber board more and more thinner and first high densification, the deformation processing that will apply in the local density contrast situation of extrusion billet (gut) will promote so consumingly, even to such an extent as to for the density fluctuation on very little surface for example also may cause impression in steel strip surface or or even the destruction of steel band because the coma ball in extrusion billet or glue lump.
The manufacture of extruded stock pad, also referred to as becoming parison band (Formstrang), is that the material that will process by distributor is dispensed onto on forming strip and realizes, and after this by a weight per unit area scale, realizes the control of extruded stock pad and/or density are controlled.Usually as metal detector, also establish other magnetic separator and search coil, the first press for to the just compacting of extruded stock pad, divides single device to the edge-neatening apparatus on limit, extruded stock pad longitudinal side and the necessary base pad before beat-type press.After this defect base pad cylinder is also set in the prior art or also can be throwing bucket, so as by bad spreading or with the extruded stock pad of defective material spreading, before press entrance, from this one-tenth parison band, take out and prevent from entering compacting fast and reliably.The reason of doing is like this to save actual raw material because generally also from throwing bucket, used material is input to not only raw material preparation work and but also be used in next machine circuitous in.As by Hansgert Soine ', " timber is manufactured and processing " that 1995DRW-publishes, in page 72, accompanying drawing 118, institute describes and illustrates, and the extruded stock pad of first compacting fractures at whole width during the throwing from forming strip.The fracture characteristics of extruded stock pad in the throwing of defect base pad or above throwing bucket is to depend in the nature of things the type of applied material and spreading, first pressing truth condition, the type of adhesives and other factors.Conclusive, in the fiber gauze pad situation lower section piece formula fracture of compacting, be general and the known fact.According to material difference, also may occur by the phenomenon of rupture on extruded stock pad width, however the general fracture arris that can not produce straight line, but how much be tooth type (disconnected rib), it may have along producer to the spike showing.
First all single member that is equipment in starting operation moves in idle running high speed, and wherein all devices member started rapidoprint before continuous working press.Correspondingly, by the material of spreading on forming strip, form extruded stock pad, it is scavenged in a throwing bucket continuously.Unlatching when this throwing region keeps so long, until can manufacture extruded stock pad up to specification time only.Conclusively be, shaping weight by the extruded stock pad of spreading is regulated according to the rules, the press of continuous operation is regulated in advance and is realized necessary operational factor by correct parameter and after continuous working press the processing of this terminal (by specification, cut apart, cooling stations, stores) be to prepare to be with (Plattenstrang) for made plate shape.If extruded stock pad is being applicable to aspect its uniformity, deliver nose from throwing position along producer to sailing row and spanning throwing cylinder until the other extruded stock pad intersection point of steel band continuous working press.So far occur sometimes, in the irregular fracture arris of extruded stock pad situation, this spike stretching out can cause deflection or local compacting during entering continuous working press in extruded stock pad.And the escape producing in the entrance wedge of continuous working press due to air or steam due to irregular fracture arris causes not predictable flowing, wherein these flow and but can cause, the component of extrusion billet producer to reverse superior displacement and therefore cause density in regional area to improve fiercely.These disadvantageous effects even may cause the bilayer of extruded stock pad in entrance area, therefore in the extruding slot of continuous working press, by producing local excess pressure load (effect), to those, transmit on the element of extruding force.Therefore be generally the damage that first steel strip surface occurs.The blemish surface of continuous working press steel band impairs the surface quality manufacturing a product on the one hand, and steel band is parts the most expensive in continuous working press sometimes and will causes the production of cost cost to interrupt when each replacing on the other hand.
Also may be essential at production period problem during above-mentioned starting operation, throwing bucket is opened to remove the remnants of defeated troops of extruded stock pad.The in the situation that this for example finding out metal in extruded stock pad, in the defect cloth situation causing because of distributor or be all essential under problem condition manufacturing that extruded stock is lined with.Now may there is such situation, when the extruded stock pad of first compacting starts without have phenomenon of rupture just to continue to enter into the press of continuous operation and the compatibility by its material internal also bridge get over throwing number of regions second.This may appear at feeding (speed) and be greater than in the situation of 1m/ quick operation production per second.Although just in time having this knowledge early in impurity situation to go out the damage that yet may allow it enter into the press of continuous operation and caused steel band.And product may be the reason that extruded stock pad is ruptured and make continuous working press dry running in width or the adjustment aspect thickness of plate of material.
With file, shown several open texts in the prior art for those reasons, they specialize in production period work of cutting apart to extruded stock pad before the entrance area of press.DE102004048275B3 has shown a device from extruded stock pad to press that carry.What in this device, emphasize is, base pad slinger consists of the movable nose of delivering unlike traditional, but being set to throwing platform rotatable or can deflection supporting, it is arranged on on the transfer position in parison band transporting flat and it can turn to a throwing position from transfer position in order to cut apart with throwing at least a portion base pad.Wherein this becomes parison band to be separated.The essence of this device is, the run-on point of throwing platform is configured in into the below of parison band.Therefore in the end of extruded stock pad, produced curved cutting arris, upper increase (comparison diagram 6) that forms this cutting arris of its height (direction) above forming strip.During this can occur in compacting or after compacting, by press, run between the expulsive stage of fracture fragment, these fracture fragments no longer may contact with extruded stock pad or form with it stitch but bond to the pollution (referring to Fig. 7 and 8) that causes press on following steel band and in backhaul.More difficult, the solidified shell forming on lower steel band or bonding scab are damaged the surface of product in a periodic manner.Even in end product (plate of material), minimum indentation or unevenness also can manifest ugly pattern after the pad pasting with is as thin as a wafer pasted.These bonding phenomena also can not be remedied with screeding device in the backhaul of steel band, because be difficult to and only have by powerful mechanical energy and just can dispose with similar these adhesive of combustion residue on cooking utensil bottom.In addition, in this open file paper the queueing problem of defect base pad or defect cloth, wherein seldom speak of the cut quality of extruded stock pad end.
DE3914112A1 has shown that one for suppressing continuously the equipment of an extruded stock pad, wherein the entrance side above forming strip turns to and in the region of rolling, configures a punching machine, it has one transverse to the perforation axle of forming strip throughput direction configuration and has the perforated pins of stretching out from it, the object that wherein perforated pins is cut apart for extruded stock pad be by the rotation contrary with the direction of motion of extruded stock pad of perforation axle can be embedded in this (extruded stock pad) and can be in the direction of motion of extruded stock pad, to do perforation to move.The disclosure file only provides a plurality of perforation by extruded stock pad so that the solution of a specified fracture position to be set, thereby prevents, extruded stock pad is undesirably skipped this Throwing and thrown region and dangled in short-term before its fracture.In addition, after the perforation of extruded stock pad or after its fracture, will produce sawtooth end and uncontrollable fracture fragment (referring to Figure 4 and 5).
DE102005052943A1 has introduced the method and apparatus with the press manufactured materials plate of continuous operation, and it carries out a separation cuts of being undertaken by extruded stock pad width before the press of continuous operation, preferably use machining throw (
) and excess stock be not to be scavenged into Throwing to throw in bucket and by aspirator, clear exactly.Also described, applied a knife rest that what is called can decline.The Qie Ge Blade of forming strip planar configuration is only provided perpendicular to or has been orthogonal to for separating of two devices of cutting.And also provide herein, will uncontrollably drop during the entering arris or leave the compacting at arris place of extruded stock pad fracture fragment therefore produce the coagulum that is difficult to be eliminated, because little fracture fragment can not continue to be provided to colder material (extruded stock pad) by the heat energy of steel band conduction.
Task as basis of the present invention is now; create a method for the moving extruded stock pad of cutting connection reforwarding; the entering arris and leave arris and be so shaped of extruded stock pad wherein, so that they can not produce the harm of steel band or other machines element and this lower steel band is so protected that to avoid the fracture debris damage dropping extruded stock pad end and the contamination hazard of avoiding so bringing simultaneously.Can also create in addition a segmenting device, it can be realized, by the extruded stock pad of motion continuously, the special desired configuration scheme of cutting apart and determine the relative forming strip of this segmenting device after just compacting with simple technique with mode simultaneously.
By claim 1, point out the inventive method solution, extruded stock pad enters entering arris or leaving arris in press at starting operation or when out of service and so forms structure setting by segmenting device, when starting operation enter arris in the surface of forming strip side of extruded stock pad first enter press in and/or when produce while finishing extruded stock pad leave arris in the forming strip side surface of extruded stock pad as the latter, enter in press.
Solution for independent segmenting device, but it is also suitable for implementing the inventive method, the segmenting device that has rotation rounding knife by least one forms, its producer be upwards configured in press before, wherein the radius of turn of the rounding knife of this segmenting device almost touches the radius of turn of delivering the radius of gyration of forming strip on nose and/or the rounding knife of segmenting device and when interrupt run, almost touches the radius of gyration of Intermediate Gray when starting operation.According to the definition in the application, forming strip rests on the radius of gyration that turns at that time the region rolling on to be called forming strip.
Show, manufacture and enter the simple geometry rising of arris and leave the starting process being protected that the geometry falling under arris can be realized continuous press.Rounding knife described herein is carried out a kind of cutting of passing through extruded stock pad conduct of combing formula and preferably directly delivering on nose or before being close in it and with optimal way of forming strip, unnecessary extruded stock cushion material is passed in throwing bucket in starting operation.Meanwhile, delivering nose starts bridge and gets over this throwing cylinder and go to the delivering on position of intermediate conveyor belt before press.The separation cuts of wherein carrying out on the width of extruded stock pad is so realized, so that any displacement or deflection do not appear in the part by entering press of the extruded stock pad retaining on forming strip.The in the situation that of fault or production change, will implement separation cuts equally, this straight line separation cuts being on the extruded stock pad end just entering should make the transition from production run to press free-runing operation become easy simultaneously.And when throwing bucket is opened the throwing characteristic of extruded stock pad be enhanced and herein by extruded stock pad with produce opposite direction comb formula (
) cutting or combing excision (
) can not produce any deflection deflection on extruded stock pad end.Wherein the separation cuts of segmenting device is preferably implemented as on the vertical line of relative extruded stock pad longitudinal edge rib.Because should only have uniform pressure-acting on steel band at width, therefore can prevent the skew of steel band and/or Roller Shaft.This separation cuts is preferably used in the rounding knife of straight line on extruded stock pad width and implements.According to applied field should rounding knife also may be embodied as tooth-like structure.Next and knownly there is almost the evenly prior art of cutting edge and differently implement cutting apart of extruded stock pad in the applicable cases of tooth-like structure.
Extruded stock pad by such generation leaves the shape of arris and just with advantageous manner, avoids, fracture fragment or explosion partly drop to bonding on lower steel band and during pressing process and hard solid there.Exactly by the present invention, instructed and can be realized, these fracture fragments are retained on extruded stock pad or in its remaining part, and it is still mutually bonding with the plate of material of just hardening.Therefore also guaranteed in addition waste heat from fracture fragment (heat) be transmitted to the extruded stock pad end of more material and therefore this fracture fragment also to leave uniformly end mutually bonding with extruded stock pad, its (extruded stock pad) is done longlyer on forming strip side or lower steel band, and along with the end of leaving of plate of material is sent from press, these (fracture fragments) can not hang and remain on steel band simultaneously.During identical effect also occurs in starting operation.Even during the compacting in press entrance area when only, also can be caused entering floating or the fragment that ruptures of arris place during to exhaust on the contrary with producer in short-term.And these particles are fallen again on the start-up portion that extruded stock pad moves ahead and extrusion process with during hardening process together with plate of material bonding.In a preferred embodiment extruded stock pad enter arris and/or leave arris by this method or by this segmenting device on extruded stock pad width cut apart by have straight line or at least near linear and until cut uniformly extensions.During formation enters arris or leaves arris, definite extruded stock pad part that is not used in press can be removed by forming strip, wherein these parts are sucked away or are pushed in throwing bucket.
As preferably, entering arris and/or leaving arris of extruded stock pad has the straight line that highly edges up or decline.And can expect, form declivity or upper oblique, near forming strip side surface, there is hillock shape enter arris and/or leave arris, to strengthen, returning of fracture fragment stayed to effect.In this correlation, it will also be appreciated that entering arris or leaving the shape of arris below: wedge shape.Press optimal way, this rounding knife can embed or cut this extruded stock pad during be provided with vibration, to improve cutting apart the embedding of extruded stock pad and/or its.The rotation that can make whole segmenting device or rounding knife for mobile cutting close on be embedded into extruded stock pad in before or during there is the velocity component of level, it is opposed on the contrary to identical or contrary with it line of cut with producer that it is directed relatively at that time.Therefore during cutting process segmenting device from entering arris or leaving arris and remove.
