Description

Make the method and apparatus of batten

The present invention relates to a kind ofly make the method for batten by round log, wherein batten in the length of grain direction between 200 to 350mm, and perpendicular to the width of grain direction and thickness between 1 to 15mm.Next the present invention relates to a kind of device of being made batten by round log, be used for cutting the topping machanism of batten with a round log conveying device and at least one, wherein batten in the length of grain direction between 200 to 350mm, and perpendicular to the width of grain direction and thickness between 1 to 15mm.

For example by known a kind of above-mentioned these class methods of DE3837200C1 and device.

As everyone knows, woodwork such as wooden frame or plank can be made with leftover bits and pieces without the monoblock solid wood.The sort of woodwork of being made up of so-called " batten " except known (thick) sawdust-board and (approaching) sawdust-board also is widely known by the people, batten also is called " wood chip (Wafer) " or " thin slice " in professional language, leftover bits and pieces is interpreted as to have ratio as the bigger size of the subsidiary wood shavings that form when cutting side, wooden unit nature hypotenuse or the like here.Under the more typical situation batten in the length of grain direction between 200 to 350mm, and perpendicular to the width of grain direction and thickness between 1 to 15mm.These battens are by splicing and the bonding woodwork of making, for example plank or beam column, and this is referred to as " joggle beam ", " splice floor board " or " structural timber product ".

Everybody also knows for this purpose, and the bonding one-tenth of batten is had certain moulding of certain width, length and thickness, the oblique seamed edge determined of band also in some cases, thus can be with batten by bonding one-tenth plank in orientation and the beam column determined.

By the known a kind of wood cutting lathe that is used for making this planer sheet or batten of the described DE3837200C1 of beginning.Should make the planer sheet on big plane with definite thickness, width and length with this known lathe.Round log is sent into cutting roll on the edge perpendicular to the direction of its extend longitudinally line for this reason.Cutting roll comprise an outer cutting tumbler and one be positioned at inner, with its concentric impact tumbler.These two tumblers drive to opposite direction of rotation.Wherein cut tumbler and downcut wood chip from width one side of round log, it enters the inside of cylinder, is impacted the planer sheet that tumbler is divided into the expection with definite size there.The planer sheet that is formed by this method leaves cylinder inside by means of a plate washer, and delivers on the conveyer belt.

The diameter of cutting roll reaches 60cm approximately in this known lathe.With the smaller round log of the about 15cm of this known lathe processing diameter, just branch of Qie Duaning or the like.Here round log is cut off fully.

By US4371020 and the known a kind of method of making long stuff of US421149.Round log passes cutter arrangement at first vertically in this known method, on the diameter at round log in this device four cuttves is housed altogether, and they stagger 45 ° mutually.Round log axially by cutter arrangement, makes round log be divided into eight fan-shaped wooden units of radially cutting open altogether after by cutter arrangement.And then these wooden units by one that form by fixed blade, form fan-shaped device, make it to form the batten that parallels to the axis.Wherein batten radially has different width.Therefore then they are by a cutting rolling device, here it is resolved into elongated, in cross section, be foursquare pin chips.

Round log used in this known method also is cut off fully.

By the known a kind of method and apparatus of making batten of US4681146.Here batten is made by the round log of having mentioned equally, and at this moment it moves on a planing machine platen in width one side of a feed station with it.Cut into the planer sheet by the planing machine platen round log that moves back and forth.Then the planer sheet is further cut apart by means of rolling tool (Messerwalzen).

Round log also cuts away fully in this known method.

By DE3114843A1 known a kind of so-called " forming method ".Whole trunk is at first made section bar in forming method, that is to say with angular cutter and molding cutter longitudinally to process.The result of this processing is so-called module.This can be understood as the woodwork with radiation shape of cross section, and it is made under the condition of maximum volume recovery and is suitable for follow-up thin plate and the beam column of resolving into of module.

The part of being downcut or cutting away by molding cutter and angular cutter in common forming method becomes the wood shavings sheet, and they are further processed in pulp industry (Zelluloseindustrie) and sawdust-board industry.

By the known a kind of device that on the tree bar, processes many cannelures by means of saw blade simultaneously of US4149577.

The objective of the invention is to by contrast: improve the described the sort of method of beginning, beyond smaller round log (branch) is cut this application region fully, also can make batten even make.

Solve like this according to the present invention by this purpose of the described method of beginning, round log is an independent trunk all the time, process cannelure at first for the nubbin of trunk beyond the effective product section of trunk, the width in their spaces downcuts batten from whole nubbin then.

Secondly by solving this purpose like this: design a conveying device of carrying single trunk by of the present invention, the described this device of beginning, make can load onto at least one with the trunk topping machanism that part whole nubbin in addition is meshed of becoming a useful person, topping machanism has the first group of cutter that is used for opening cannelure on nubbin simultaneously, wherein the width in cannelure space.

Can fully solve with this method according to purpose of the present invention.

The present invention fundamentally is different from the known method of making batten up to now.Known these methods are limited to such raw material, promptly above-mentioned round log, and it is machined away when making batten fully.Therefore only consider smaller round log as raw material, the branch of Qie Duaning just, thick branch fork and the trunk of very little tree in addition perhaps.

Different therewith the present invention expand the range of application of the method for making batten and corresponding device thereof to solid wood that those handle big round log.Just only part is cut away and the remainder of trunk is processed into the method for processing wooden piece of the sort of trunk of big woodwork.This method of processing wooden piece has very big meaning aspect economy, will use within a large range.

With usual way and device processing trunk the time, always only produce flaking or sawdust, even and make for the first time within the scope of the invention under this application scenario can also the production high value leftover bits and pieces, batten just.

This promoter for wood processing equipment has tangible economic implications, has won increasing meaning because add the sale that attaches the secondary products that forms man-hour at timber at economic aspect.Also can common whole trunk carries out subsidiary formation on the equipment of processing under the situation of flaking with it at those to the manufacturing of this batten.Only need through smaller repacking or additional equipment at this.Therefore the economy of these equipment can improve significantly with expense seldom.

In first kind of said method selective refinement scheme, in a unique operation, in the cross machine groove, cutting into the batten that thickness d length is l between the cannelure.Correspondingly too for the embodiment that presses device of the present invention, at this moment topping machanism has cutting element along throughput direction in the downstream of first group of cutter, and it is cutting into the batten that length is the l thickness d by cutting when processing transverse groove between the cannelure in a unique work step.

Then opposite in second kind of selection scheme of this embodiment of the inventive method, nubbin at first processes later the transverse groove of the length l in space in first work step at the processing cannelure, in second work step, cut into batten then with thickness d, correspondingly too for the affiliated embodiment that presses apparatus of the present invention, at this moment topping machanism has and is used for second group of cutter of on nubbin cross machine groove, length l in transverse groove space wherein, and contain along the downstream of first group of cutter of throughput direction and second group of cutter and to be used for batten is cut into the 3rd group of cutter with thickness d.

Above-mentioned measure has the following advantages: can make the batten with the size that can change in two selectable methods on a large scale, wherein length, width and gauge can be given in advance exactly.Secondly can make down battens bevel or other configurations by the corresponding moulding of cutter.

Secondly preferably like this, at first on two of trunk relative sides, cut batten turning on two opposite flanks of 90 ° of trunk then by the embodiment of the inventive method.

This measure has the following advantages, and it can be used for known processing sequence, known to for example in forming method like that.So for example can adopt two stations that set gradually along throughput direction, the trunk of partial operation is along its longitudinal axis half-twist between these two stations.Also a this processing stations can only be set as a kind of selection scheme, trunk is half-twist after leaving processing stations, and delivers to the inlet of processing stations again by circulation.

Cannelure is made longitudinal incision by cutting in the preferential version that adopts by the inventive method.But also can make by sawing as a kind of selection scheme cannelure.

Correspondingly transverse groove can be made transverse incision or pass through sawing cross machine groove by cutting.

First group of cutter can be made first group of blade or first group of saw blade in by the version of apparatus of the present invention, and second group of cutter can be made second group of blade or make second group of saw blade as selection.

Represented one embodiment of the present of invention in the drawings, will further be illustrated in the following narration.In the accompanying drawing:

That Fig. 1 simplifies greatly, be used for making the side view of the device of batten by prior art;

Perspective view Fig. 2 single batten, that amplified greatly;

The lateral perspective of a trunk to be processed of Fig. 3;

Figure 4 and 5 are similar to two schematic side view of Fig. 3, in order to the work step of explanation sequencing in a kind of form of implementation of this method;

Fig. 6 to 11 passes through the radial slot according to the trunk of the view of Figure 4 and 5, in order to the work step of explanation sequencing.

The lateral perspective of a kind of embodiment of Figure 12 apparatus of the present invention.

Among Fig. 1 10 generally expression make the usual means of batten.By means of the feeder 11 that has a slide block 12 to turn round within it, round log 13 moves to arrow 14 directions by feeder 11.Wherein round log 13 is sent to perpendicular to its longitudinal axis.

The cutting element 20 of a rotation just in time is positioned at the exit of feeder 11.Cutting element 20 drives along direction of rotation by axle 21, as using shown in the arrow 22.Blade 23 is housed on the circumference of cutting element 20, and it protrudes in the excircle of cutting element 20.Therefore the round log 13 sent to of side direction arrives the region of engagement of the blade 23 that is rotating, shown in the dotted line among Fig. 1.

Downcut or cut off single planer sheet (Flachspan) or batten 24 from round log 13 by this method, and along arrow 25 direction separating devices 10.

View among Fig. 1 is extremely schematic.Certainly the batten 24 shown in can also carry out following process in another station, processing etc. is modified in for example further cutting on seamed edge, just as at length knowing in the prior art of being quoted by beginning.

Fig. 2 represents the view of an amplification of batten 24, to show it and the common chips or the difference of other wood chips.Distolateral 26 of batten 24 clearly manifests the wood grain 27 of timber.Batten 24 in the length l of grain direction significantly greater than respectively perpendicular to the width b or the thickness d of grain direction.

In fact the length l of batten is between 100 to 350mm, and width b is between 1 to 15mm, and thickness d is between 1 to 6mm.But also can be different with these numerical value.

With shown in Figure 2 different, batten 24 also can have the non-rectangle structure, and for example rhombus becomes other structures, thereby batten 24 can be spliced mutually bonding one-tenth joggle beam (Kompositbalken) or plate, so-called " splice floor board " by certain orientation and position.

Fig. 3 is schematically illustrating round log 30 equally, just solid trunk.The major product of on trunk 30 microcephalies' end face, having drawn (position) (Hauptware) 32.These central authorities that can be understood as at trunk 30 have rectangle or the long-pending zone of square cross section.This affiliated zone is equivalent to be used for making major product 32, the just zone of beam, plank or the like on the trunk 30.

Nubbin 33 parts that stay when common forming method are processed into the side thin plate, and a part is cut away by producing wood shavings sheet and sawing.

The special feature of this method is that shown nubbin 33 completely or partially is divided into batten 38.

Process longitudinal incision 35 and transverse incision 36 for this reason on the nubbin 33, make batten 38 can be slit into layer 37.The certain batten 38 of factory length l, width b and thickness d in this way.

When mentioning " otch " in the scope in the application, for example longitudinal incision 35 and transverse incision 36, it only is to understand as an example so.Can be understood as generally and have groove on the trunk, wherein groove promptly can be made otch by blade and also can realize by sawing.

Set forth the details of used method and wherein used device below by means of Fig. 4 to 12.Wherein Figure 4 and 5 are represented the side direction perspective illustration of two trunks 30, the cross section of trunk 30 in the different work step processes of Fig. 6 to 11 expression, and last Figure 12 represents the perspective view of equipment therefor.

At first do longitudinal incision 35 in order to process trunk 30 by Fig. 4 and 6.For being used in, this purpose trunk 30 only illustrates among Figure 12 to represent that with arrow conveying device 50 longitudinally moves, by two groups of fixed blades 51.Blade 51 forms longitudinal incision 35 on trunk 30, and downwards up to the boundary line shown in Fig. 6 40, its (boundary line) is again the lateral edges at effective product position 32 simultaneously.See that as knowing longitudinal incision 35 for example is made on 30 two relative sides of trunk simultaneously by Fig. 6 and 12.

The implication cutter 51 of Xie Shiing only is construed as example in front.The blade that for example replaces being used for processing otch can also adopt saw blade to make corresponding groove certainly.

Following process for trunk 30 has two kinds of selection schemes now:

In an independent work step doing transverse incision 36 according to Fig. 5 on the trunk 30 according to first kind of selection scheme.Here can adopt one group of corresponding cutting blade (not drawing), it vertically moves till reaching boundary line 40 deeply perpendicular to trunk 30.Trunk 30 just has the appearance shown in Fig. 3 like this.

In order to cut into the blade movement that batten 38 can make trunk 30 fixedly install towards a component level, it aims at throughput direction, and just trunk 30 is vertical, and it is slit into the thickness of predesignating with length l and the definite batten 38 of width b.For example this device was introduced in starting said US4371020.

By second kind, under existing situation the preferential selection scheme transverse incision 36 that adopts in an independent work step and the cutting of batten 38 carry out together.Adopt the cutting element of in Figure 12, representing as an example 52 for this reason.Cutting element 52 drives by axle 53.Axle 53 edges are perpendicular to trunk 30 axis 54 extensions longitudinally.Cutting element 52 rotates to arrow 55 directions in an illustrated embodiment.Cutting element 52 is equipped with the working face of taper.On a plurality of roads of taper work face layer blade 60 is arranged, they have major cutting edge 61 and secondary cutting blade 62 respectively.Major cutting edge 61 and secondary cutting blade 62 also can be made of independent blade, and they distribute along peripheral direction.In this way in the embodiment shown can be in the trunk both sides, effectively remaining position 33 cuttings that exist respectively of 32 next doors, product position.

Here since the Surface Taper nubbin 33 of cutting element 52 downcut layer by layer, as among Fig. 7 with shown in the dot-dash line of cut 42.Can cut batten 38 by the corresponding moulding of major cutting edge 61 and secondary cutting blade 62 in this way with adjustable length l and thickness d.Fig. 7 is illustrated in two nubbins 33 similar 1/3rd states that cut into batten 38.This state of trunk 30 is represented with 30a in Fig. 7.

Fig. 8 represents the state 30b of trunk 30, and the described nubbin 33 in both sides has been cut off fully when this state.Therefore a side of active component 32 completion of processing.

Therefore trunk 30 arrives the position shown in Fig. 9 around its longitudinal axis half-twist now.Be placed on processing longitudinal incision 35 ' (state 30c) on remaining nubbin 33 ＇ of side once more now by means of device by Figure 12 at this position trunk 30.For this purpose can be provided with two covers at trunk 30 throughput directions by the device of Figure 12.Both can be between two covering devices with trunk 30 half-twists, the 90 ° of installations of also two covering devices can being staggered mutually.But also can be with trunk 30 half-twist after leaving shown in Figure 12 device, come back to inlet by a circulation by the device of Figure 12.

The trunk 30 that processes so now be cut into again the nubbin 33 that has longitudinal incision ', as among Figure 10 with shown in the state 30d.Here see once more line of cut 42 ' and batten 38 of cutting '.The end active component 32 of the work step that part finishes in Figure 10 also machines, as shown in figure 11.

According to the method described above nubbin 33,33 ' fully be divided into batten 38,38 '.But certainly, if for example want a part of nubbin 33,33 ' be processed into plank may some nubbin 33,33 ' cut apart, wedge the degree of depth (boundary line 40) so accordingly and must correspondingly adjust.
