Abstract
Description
- The invention relates to a molding machine used in the working of wood.
- In the field of design and production of machines for the working of wood, and in particular molding machines, there is continual research for ways of improving the work quality of the machines, their precision and the speed with which the non-machine operative positioning operations can be carried out.
- In the case of the abovementioned machines, that is in machines predisposed for the working of all four faces of a plank of wood arriving from a feeding line, it has been noted that the tool-change times (or for a change of wood-shape) are very long and the work is laborious: the tools used, which are in the elementary and classic conformation of one for each side of the plank (with some variants for the types of work to be done), are arranged along a horizontal work plane. Drawing wheels (rubber or steel) are interpositioned between the tools and have their rotation axes parallel to the work plane and are connected in motion one to another by a posterior cross-piece: these wheels have the function of drawing the workpiece along the operative advancement direction, feeding it continuously to the tools.
- The tools (which, along the feeding line are respectively defined as the lower horizontal, the right vertical, the left vertical and the upper horizontal) are covered by a protection casing also functioning as an aspirator of the sawings, and are equipped, each bilaterally and outside the casing, with pressing elements to maintain the workpiece in a guided position before, during and after its working; more precisely, the front presser is arranged in an inclined position to invite the workpiece towards the tool, while the posterior presser is positioned parallel to the plane and is at a distance from the plane depending on the thickness the finished workpiece is to have.
- Recently it has been noted that the substitution of one or more of these tools, for a change of shape or profile, is lengthy and laborious: the operator must substitute the tools after removal of the protection casing, disengaging it with respect to the posterior cross-piece which supports it; then the operator must set the new tool on the same work plane (according to its new diameter), by means of special handwheels and using graduated scales situated on the machine itself, with which scales it is possible to control, by varying, the distance and/or the height of the rotation axis of the tool from the work plane. Once this phase has been carried it is then necessary to reposition the casing according to the new size and dimensions of the new workpiece.
- Thus it can be seen from the preceding summary description, that the substitution of each single tool brings about a work time which is rather long on the part of the operator, apart from the fact that the precision of the repositioning of the new tool and the pressers (casings) depends, in a great number of cases, on the operator's experience.
- To this end the present Applicant made an improvement in a molding machine (see Patent Application IT-3518A/90) in which it was envisaged that each of the tools is supported by a relative positioning slide, mobile in an orthogonal direction to the work plane for the positioning of the tool, and is equipped with a casing to which the pressing organs are solidly and laterally connected, which casing is equipped with regulation means acting between the casing and the slide, which regulation means can vary the distance with respect to the work plane according to the reference diameter of the tool with a reading device associated to slide able to indicate, on a digital reading scale, the values of the relevant distances.
- Thanks to this improvement, the molding machine is more rapid and precise in the positioning of the tools, in in the change of shape, and works with a considerable precision. As often happens, however, the improvement influences the design of the machine it derives from, giving rise to "hybrid" machines with costs that are relatively high.
- The aim of the present invention is thus to eliminate the above-mentioned drawbacks by providing a molding machine for wodd workpieces which is precise, rationalised with regard to all of the tool- and shape-change operations, so as to enable an improvement in the relative work operations.
- The technical characteristics of the invention, according to the above-mentioned aims, emerge clearly from the contents of the following claims, and the advantages of the invention will become more eviding during the detailed description that follows, made with reference to the enclosed drawings, which represent an embodiment which is purely in the form of a non-limiting example, and in which:
- figure 1 shows, in a schematic side-view with some parts removed better to evidence others, the molding machine object of the invention;
- figure 2 shows, in a schematic plan view from above, with some parts removed in order better to evidence others, the machine of figure 1;
- figure 3 shows, in a side view with some parts in section and other removed in section, a detail of a tool of the machine of the preceding figures;
- figures 4 and 5 show respectively in a plan view from above and lateral with some parts removed in order better to evidence others, and other parts in section, a further tool of the machine of the previous figures;
- figure 6 shows a kinematic design of the movement groups of the tools of figures 5 and 6.
- With reference to the figures, the molding machine in question is of the type which works on four sides of a plank of wood and comprises (see in particular figures 1 and 2) a
station 1 disposed close to a horizontal reference andtransport plane 2 for the four-sided working of theworkpieces 3 supported on arelative base 4; naturally some parts of the machine have not been fully illustrated since they are bearing structures, and some devices used are already very well known. - The
station 1 essentially comprises four working tools for the workpieces 3 (see figures 1 and 2) which tools, following the advancement direction of theworkpieces 3, (indicated by F in figures 1 and 2), are known as lower horizontal 5, right vertical 10, left vertical 11 and upper horizontal 6; the denomination indicates the side of theworkpieces 3 that each single tool works on (or the plane to be worked on itself). Each of these tools is supported bycorresponding slides guides 7 and 12, each of these four tools is equipped with arelative casing -
Pressing organs casings organs workpieces 3 for the relative work operations. The saidpressing organs strip couples front strip 41 is inclined with respect to thetransport plane 2, while theback strip 42 is parallel with respect to the saidtransport plane 2 so as to permit the guiding or the invitation or the stabilising of theworkpieces 3; while the rightvertical tool 10 is equipped with a guide pair, of which one G stops theworkpieces 3 and one G1 functions as a mobile reference in such a way as to enable relative variation in the distances according to the thickness of the shaving to be planed off. - In figures 1 and 2 17 denotes roller means arranged over all of the horizontal plane and constrained to a cross-bar T posteriorly disposed with respect to the
transport plane 2 and aimed at permitting the drawing of theworkpieces 3 from one tool to another. These roller means are constituted bywheels 43, made of steel or rubber, regularly distributed over all of thetransport plane 2 so as to permit theworkpieces 3 to be drawn. - As can be seen in figure 3, the upper
horizontal tool 6 is regulatably mobile on thecorresponding slide 7s and is equipped with acasing 8s solid to it to enable a variation to be made in the distance with respect to the plane to be worked on according to a reference diameter D of the tool and a height H of theworkpiece 3. - More in detail, the
horizontal tool 6 is supported by avertical column 18, which is arranged posteriorly with respect to thetransport plane 2 and is constrained, by means ofvertical guides 19 defining theslide 7s, to thebase 18; thecasing 8s is is solidly constrained to theguides 19 and is also superiorly equipped with a sawdust and shaving aspirator andcollector 8t. As can be seen, again in figure 3, thehorizontal support shaft 6a of thetool 6 is constrained, through the relative slide supports 20, to theguides 19 so as to permit a relative regulation between the upperhorizontal tool 6 and thevertical column 18. - In figures 4 and 5, only the left
vertical tool 11 is visible, which is equipped, like the rightvertical tool 10, with amobile arrest plane 15s for theworkpiece 3, which is interplaced between theslides tools vertical tool 11, on thecasing 13s, on thetool 11 and on the saidarrest plane 15s, while with regard to the rightvertical tool 10 they only act on the tool itself and on the relative plane 15d to enable a variation to be made to both, in consecutive series or independently between successive and preceding, of the distance of the plane to be worked on according to a second reference diameter D1 of thetool 11 and the breadth L (for the upper left) or the breadth S (for the right vertical) of theworkpiece 3. - More precisely, the left
vertical tool 11, illustrated purely by way of example since the two vertical tools are identical and equipped with theslide 12s having a horizontally-developing base on which thecorresponding casing 13s is slidably constrained with relative pressing organs 14: thecasing 13s is constrained inferiorly on aparallel relief couple 21 equipping theslide 12s to which asupport cylinder 23 of a tool-bearingshaft 11a is slidably constrained, at the end closest to thework plane 2 and in acorresponding seating 22. Obviously theplane 15s interplaced between thecasing 13s and theslide 12s, theplane 15s has a greater mass than theslide 12s itself and exhibits a pair ofslots 24 for the passage of therelief couple 21 constraining thecasing 13s and acircular seating 25 for the passage of the tool-bearingshaft 11a. - The left
vertical tool 11 as it is structured equips the above-mentioned regulation means 16, which are constituted (see figures 4 and 5) by afirst casing 28 defining a part of theslide 12s; thecasing 28 is inferiorly arranged with respect to thetransport plane 2 and exhibits aplate 29 equipped with twoconstraint reliefs 21 of thecasing 13s and a first and secondhorizontal regulation screw 30 and 31: the first of thescrews 30 is screwably connected to a correspondingfirst nut seating 32 exhibited by thesaid base 4, arranged on the opposite side of the machine with respect to theslide 12s, so as to enable the movement from the outside of the protection casing of all of thecasing group 13s and pressing organs 14 - tool 11 -plane 15s; thesecond screw 31, parallel to the first, is screwably constrained at its internal end to asecond nut seating 33 made on asupport plate 34 defining the shaft-tool bearinggroup 11a and is aimed at permitting the movement, independently of the preceding setting, of the tool 11 -plane 15s group with respect to thecasing 13s. - Parallel to the
first casing 28 is asecond casing 35, arranged by the side of the first casing and rigidly fixed to it and also to the tool-bearing group by means of a rigidcentral bar 36 which exhibits a thirdhorizontal screw 37 screwably inserted in a relativethird nut seating 38 made on abridge 39 which is rigidly connected to theplane 15s in such a way as to permit a single and independent transversal movement, independent with respect to thetool 11 and to thecasing 13s, and transversal with respect to theplane 2. This type of regulating structure is also made in the rightvertical tool 10, apart from the first regulatingscrew 30 of thecasing 13d since it is fixed to theslide 12d. - The
second casing 35 can also exhibit a fourth regulating screw 40 (illustrated by a broken line in figure 4) parallel to the previous ones and connected to the tool-bearinggroup 10a and 11a in such a way as to enable an axial height regulation with respect to thework plane 2; such regulation is effected thanks to a kinematic connectection between thescrew 40 and the tool-bearingshaft 10a and 11a (not illustrated herein since of known type). - The molding machine as it is structured herein functions in the following way: the operator, when he must newly set the machine tools, when a new work operation is about to begin or when a worn tool is to be substituted, merely has to substitute and reposition the lower horizontal 5 and right vertical 10 tools and according to the new dimensions of the
workpiece 3, which are functions of the diameters D and D1 of the relative new tools and height H and breadth L of theworkpiece 3. The setting is thus effected, after having opened therelative casings 8i, 13d and having substituted thetool transport plane 2 which, concerning thehorizontal tool 5, is equal to the entry height of theworkpiece 3 minus the predetermined thickness t to be removed (or He - t of figure 1); regarding thevertical tool 10, the distances are equal to the entry breadth minus the thickness S to be removed, which is also predeterminable (or Le - S of figure 2). Once this first regulation has been effected, the operator goes on to define the settings of the leftvertical tool 11 and those of the upperhorizontal tool 6 which define the exit breadth and the exit height of theworkpiece 3 from the station 1 (respectively final Lu and Hu of the workpiece 3), or the thickness not removed by the preceding tools. Regarding the upper horizontal 6, the phases are the same as the preceding except for the fact that it is possible subsequently also to regulate the height of the tool-bearing shaft 8sa with respect to thecasing 8s. - As for the left
vertical tool 11, the regulation happens in three distinct phases, and for greater clarity these movements can be seen in figure 6, wherein the kinematic connection of the various elements is shown schematically: as soon as thetool 11 has been substituted with the new one, and thecasing 13s has been reapplied, the operator proceeds to the first regulation of thecasing 13s with the relativepressing organs 14 through thefirst screw 30 which causes the advancing or the retracting (see arow F1) of all of the casing-tool-plane groups at distance Lu; once this operation has been done the operator brings thetool 11 to the edge of the casing (see arrow 2) thanks to thesecond screw 31 beining behind it also theplane 15s, but no longer thecasing 13s. Finally the operator proceeds to the definitive setting of theplane 15s by using the third screw 37 (a function of thetool 11 diameter and indicated by F3) so as to arrange the edge of the seating at the edge of thetool 11 so as to permit a better lie of theworkpiece 3 in arrival. - Summarising, there occurs a regulation of the elements in series starting from the casing which time by time however distances the just-regulated element so as to enable a faster positioning of the successive elements.
- Naturally the operator can further regulate the
tools screw 40 at the height of thetool work plane 2.
