Definitions
- the invention is pertaining to the field of the methods of production of corrugated constructions with a folded structure used in the capacity of a filler of multilayered panels.
- the core structure typically is lightweight yet strong, because it has a configuration including hollow spaces as well as interconnected material webs or the like.
- Typical examples of such core structures include corrugated sheets, honeycomb cellular structures, and the like.
- Known core structures have a variety of different configurations, and are made of a variety of different materials.
- folding methods for folding sheet or web materials can be divided into intermittent or discontinuous processes, for example as described in US 5234727, as well as continuous processes.
- Such continuous processes can be divided into processes with a coupled or mutual lengthwise and crosswise contraction with a simultaneous expansion in the thickness direction of the starting material web (with a single-stage folding operation, for example as disclosed in US 5947885), and processes in which the material web is first subjected to a crosswise contraction and is subsequently subjected to a deformation in a lengthwise direction of the material (in a two-stage folding operation, for example as disclosed in US 4012932).
- a device for producing a zigzag crimp comprising shaping members reciprocating over a base in guides arranged on both sides of the material being molded.
- the drive unit of the systems of punches is in the form of a detachable vacuum chamber formed by a bag of gas-tight material capable of sealing said chamber at a side of a blank fed to the working zone between the upper and lower systems of punches.
- said vacuum chamber follows the contour of the upper and lower punches.
- US 6913570 Disclosed in US 6913570 are method and apparatus for producing a composite structural panel with a folded material core.
- a folded core structure is produced by embossing fold lines into a flat planar material web, initiating folds along the fold lines on the upper and lower surfaces of the material web, proceeding with the formation of the folds along the fold lines to deform the material web from its two-dimensional starting configuration to a three-dimensional folded configuration, and post-processing the folded material web to stabilize or fix the folded configuration thereof.
- a composite structural panel is produced by bonding a cover layer onto at least one surface of the folded core structure.
- An apparatus preferably includes embossing or creasing rolls to form the fold lines in the material web, air nozzles or folding rolls to initiate the folding process, bristle brush rolls to complete the folding process, and further folding rolls to enhance and fix the folded configuration, optionally in combination with heating, cooling, applying a coating onto or impregnating a resin or binder into the material web.
- This known invention allows carrying out continuous production of a composite structural panel with a folded material core; however, the apparatus implementing this method has therewith a complicated design and, because of its linear arrangement, has substantial overall dimensions.
- an apparatus for corrugating a sheet material comprising: one system of punches consisting of identical flat shaping members in the form of parallelograms jointly coupled along their sides and forming a zigzag corrugated surface; a drive unit for the system of punches in the form of a detachable vacuum chamber embracing them and made of an elastic gas-tight material so that it is capable of being sealed at a side of the blank fed to the working zone and replicating the contour of the counter-punches in the process of shaping-evacuation; a member for fixing the system of punches; and a mechanism for tensioning the shaping unit.
- the system of punches and its drive are made up so as to form a shaping unit.
- the member for fixing the system of punches is made of a gas-tight cloth and connected to one side of the system of punches along zigzag lines of protrusions.
- this apparatus carries out the following steps:
- said sheet material is fed on a relief drum having a shaping surface formed by a casing of a substantially cylindrical shape, said casing provided with a plurality of similar flat rigid plates arranged in the form of parallelograms jointly coupled at their sides; providing adhesion of said sheet material to the shaping surface; and deforming the shaping surface of the relief drum by mutual movement of said flat rigid plates in the casing together with turning simultaneously said relief drum around its axis.
- the plates are moved in two directions: along the elements of the cylinder determining the shape of the casing and in the circumferential direction perpendicular thereto.
- the sheet material is pressed against the shaping surface substantially at the half of the circumference of the cylinder base determining the casing shape.
- the step of removing the molded core further includes calibrating the formed crimps by height.
- the relief drum used in the method described herein above comprises: a shaping surface and a supporting structure, wherein said shaping surface is formed by a casing of a substantially cylindrical shape, said casing provided with a plurality of similar flat rigid plates arranged in the form of parallelograms jointly coupled at their sides; and said supporting structure comprising:
- each beam being fixed on a spoke connected to a disk attached to a driving shaft rotatably mounted in an immovable support, wherein one of the spokes is rigidly bound to said disk, whereas the other spokes are arranged on the disk so that they can turn in the plane of the disk; - holders of the casing arranged on the beam so that they can slide along the beams;
- said mechanisms are configured so that, within one turn of the shaft, an angle between the adjacent spokes and distances between the holders on the corresponding beams change, and when the angle between the spokes is at its maximum, the distance between the holders on the corresponding beams is also at its maximum, but when the angle between the spokes is at its minimum, the distance between the holders on the corresponding beams is also at its minimum.
- the casing is a sandwich including three joined together layers, wherein the middle layer is formed by plates with clearances between their sides, and the two other layers are fluoroplastic films, so that the portions of the films covering said clearances essentially form a hinged joint of adjacent plates.
- said layers may be joined together by gluing.
- the mechanism for mutual angular displacement of the spokes comprises:
- the mechanism for mutual displacement of the holders comprises: - sliding members arranged on each beam and carrying the holders of the casing;
- pantograph placed along each beam and comprising a few pairs of hinged intersecting levers, wherein the axles of the hinges coupling said intersecting levers are connected to the sliding members;
- the subject-matter of the invention is also an apparatus for producing a core of prepreg in the form of sheet material for composite structural panels, said apparatus comprising a forming device and a means for removing the molded core.
- said forming device comprises described above relief drum and a holding-down device comprising rolls rotatably attached to a rigid frame and encompassing the casing of the relief drum essentially along a half of the circumference of the base of the cylinder determining the casing shape; whereas said means for removing the molded core comprises a frame with rolls rotatably attached to the frame and arranged in two rows opposite one the other, wherein their axes lie in two substantially parallel horizontal planes so that there is a clearance between the rolls of the upper row and the rolls of the lower row, said clearance corresponding to the predetermined crimp height of the molded core.
- the rolls of the holding-down device are configured so that their position relative to the casing of the relief drum can be adjusted.
- the means for removing the molded core comprises an additional roll located in the lower row of the rolls on the side facing the relief drum.
- the rolls of the means for removing the molded core are configured so that their position can be adjusted in a substantially vertical direction.

- Fig.7 is a perspective view of the beam and the mechanism for mutual displacement of the holders, but without the side rings.
- Fig.8 is a perspective view of the casing of the relief drum according to the present invention.
- Fig.9 is a perspective view of a part of the casing shown in Fig.8.
- Fig.l explains schematically the principle of shaping up a corrugated surface of sheet material in accordance with the present invention.
- prepreg in the form of sheet material 1 is fed to a smooth area of the shaping surface of a relief drum 2, and this sheet material is pressed against said area so as to provide adhesion of said sheet material 1 to the shaping surface.
- the shaping surface of the relief drum 2 is formed by a casing 3 of a substantially cylindrical shape, said casing provided with a plurality of similar flat rigid plates 4 arranged in the form of parallelograms jointly coupled at their sides (Fig.8).
- the design of the relief drum 2 will be described below.
- deforming the shaping surface of the relief drum 2 is carried out by mutual movement of said flat rigid plates 4 in the casing 3 with a simultaneous turn of said relief drum 2 around its axis.
- the plates 4 are moved in two directions: along the elements of the cylinder determining the shape of the casing 3, and in the circumferential direction perpendicular to the direction along the cylinder elements.
- said sheet material 1 pressed against the relief drum 2 by means of a holding- down device 5 with rolls 6 takes the form of a corrugated surface.
- the apparatus allowing to carry out the stages described herein above consists of basically from the following three components: the relief drum 2, the holding-down device 5 and a means 7 for removing the molded core.
- the relief drum 2 shown in Fig.3 comprises a shaping surface of a substantially cylindrical shape and a supporting structure.
- the shaping surface is formed by the casing 3 of a substantially cylindrical shape (Fig.8), said casing provided with a plurality of similar flat rigid plates 4 arranged in the form of parallelograms jointly coupled at their sides (Fig.9).
- the casing 3 is a structure including three joined together layers. Said layers preferably are joined together by gluing. Moreover said layers may be joined together by another acceptable method of joining. For example said layers may be joined together by heat sealing. Said structure rolled up so as to form a tube, wherein the middle layer is formed by the plates 4 with gaps between their sides, and the two outer layers 8 and 9 are fluoroplastic films, so that the portions of the films covering said gaps essentially form a hinged joint between the adjacent plates 4.
- the supporting structure comprises a few beams 10 (Figs.4, 5 and 7) arranged along the elements of the cylinder determining the shape of the casing 3 and distributed around the circumference of the cylinder base. As shown in Fig.7, sliding members 11 carrying holders 12 of the casing 3 are attached to each beam 10 so as to be slideable along it. Each beam 10 is fixed to a spoke 13 connected to a disk 14 attached to a driving shaft 15. In order to improve reliability of fixing the beams 10 to the spokes 13, the latter can be provided with a strut 16 (Fig.6).
- the shaft 15 is rotatably mounted in an immovable support 17 and connected to a drive for its rotation (not shown).
- spokes are rigidly bound to the disk 14, whereas the other spokes 13 are arranged on the disk so that they can turn in the plane of this disk; hence, the spokes are capable of mutual angular displacement in the plane of the disk 14.
- the casing 3 is attached to the holders 12 so that the holders are arranged within the zone of clearances between the plates 4.
- the supporting structure comprises also a mechanism for mutual angular displacement of the spokes 13 and a mechanism for mutual displacement of the holders 12.
- the mechanism for mutual angular displacement of the spokes 13 comprises a few hinged pairs of levers 18, the free ends of which in each pair are hinged to two adjacent spokes 13.
- a roller 19 is attached to the axle of each hinge connecting a pair of the levers 18, whereas a central ring 20 having an outer edge and an inner edge is fixed to an immovable support 17 so that the inner edge 21 is in contact with the rollers 19.
- the profile of the inner edge 21 of the central ring 20 is egg-shaped so that, during rotation of the disk 14, the rollers 19 rotating over the inner edge 21 of the central ring 20 displace radially the axles of the hinges connecting a pair of levers 18 to one the other so as to turn thereby the adjacent spokes either drawing them nearer to one the other or moving them farther apart from one the other.
- the central ring 20 is a thin-sheet structure that, for saving the material when making it, can be made to consist of a few, for instance, three parts.
- each part of the central ring 20 is made in a machine tool with a software control in conformity with a mathematic model.
- the fitting holes (not shown) in the central ring 20 are made so that they are not of circular shape.
- the mechanism for mutual displacement of the holders 12 comprises the above- mentioned sliding members 1 1 attached to each beam so that they can slide along them, and carrying the holders 12 of the casing 3. Rollers 22 are attached to each of the outermost sliding members 1 1 of each beam 10.
- the sliding members 1 1 are interconnected with each other by means of a pantograph 23 placed along each beam and comprising a few pairs of intersecting levers 24 hinged with each other. In this case, the axles of the hinges coupling the intersecting levers 24 are connected to the sliding members 1 1.
- Two side rings 25 are fixed to the immovable support 17 on both sides from the central ring 20.
- the surface of each of the side rings 25 facing the central ring 20 is in contact with the roller 22 arranged on the corresponding outer sliding member 1 1 , said surface being inclined relative to the plane, in which essentially lies the central ring 20.
- the design of each of the side rings 25 is similar to the design of the central ring 20 and can also consist of a few parts that are butt-joined when mounting the parts onto the immovable support 17.
- the means for fastening these rings to the immovable support 17 are made so that they are adjustable (not shown), for instance, with the use of threaded connections.
- the side rings are placed symmetrically relative to an essentially vertical plane in which lies the central ring 20.
- Said mechanisms for mutual angular displacement of the spokes and for mutual displacement of the holders are configured so that, within one turn of the shaft 15, the angle between the adjacent spokes 13 and the distances between the holders 12 on the corresponding beams 10 change and, when the angle between the spokes 13 is at its maximum, the distance between the holders 12 on the corresponding beams 10 is also at its maximum, though when the angle between the spokes 13 is at its minimum, the distance between the holders 12 on the corresponding beams 10 is also at its minimum.
- the surface of the casing 3 is practically smooth.
- Coordination of said mechanisms is ensured by selecting both the profile and the angular position of the central ring 20 and by the magnitude of the inclination angle of the side rings 25.
- the holding-down device 5 comprises a rigid frame 26, to which the rolls 6 are attached so that they can rotate about their own axis.
- the rolls 6 are attached to the frame 26 in a few, for instance, three groups by means of brackets 27.
- brackets 27 For instance, five rolls 6 are mounted on each bracket.
- the brackets 27 with the rolls 6 are placed on the frame 26 in such a manner that, when the frame 26 is positioned appropriately relative to the immovable support 17 of the relief drum 2, the rolls 6 enclose the casing 3 of the relief drum 2 essentially around one half the circumference.
- the rolls 6 are placed on the brackets 27 so that their position can be adjusted relative to the casing 3 of the relief drum 2.
- the axles of the rolls 6 are connected to the brackets 27, for instance, by means of threaded rods inserted into the openings of the brackets 27 and fixed relative to these brackets by nuts.
- the surface of the rolls 6 can be coated with an antiadhesion material preventing sticking of the prepreg to the rolls.
- the rolls 6 can contain an outer layer of resilient material.
- the means 7 for removing the molded core comprises a frame 28 with rolls 29, which are attached to the frame so that they can rotate about their own axes, while being arranged in two rows opposite to each other.
- the axles of the rolls 29 lie in two substantially parallel horizontal planes so that there is a clearance between the rolls of the upper row and the rolls of the lower row, the clearance corresponding to the predetermined height of the crimps in the molded core.
- the rolls 29 are made so that their position can be adjusted in an essentially vertical direction. This allows, after the molded core passes through the means 7, to calibrate the height of the crimps produced in the course of molding.
- the means for such adjustment can be implemented similarly to the means for adjusting the position of the axles of the rolls 6 relative to the brackets 27 in the holding-down device 5, as described herein above.
- the means 7 for removing the molded core can comprise a supplementary roll 29a arranged within the lower row of the rolls 29 on that side thereof, which faces the relief drum 2.
- This supplementary roll 29a allows providing a support for the molded core leaving the relief drum 2 and deflecting it into the clearance between the rows of the rolls 29.
- the mechanisms of the supporting structure of the relief drum are to be set up so that the upper part of the surface of the casing 3 has essentially a smooth shape, i.e., it has neither projections nor hollows, whereas the zigzag crimps of maximum height are formed within the lower part of the surface of the casing 3.
- the crimps When passing from the upper part of the casing 3 to its lower part, at first the crimps will appear, the height of which increases up to its maximum towards the lower part of the casing 3.
- Such a shape of the surface of the casing 3 is ensured by appropriate adjustment of the mechanisms for mutual angular displacement of the spokes 13 and for mutual displacement of the holders 12 as a result of choosing both the corresponding shape for the inner edge 21 of the central ring 20 and the angular orientation of this ring, as well as due to inclining the side rings 25.
- the holding-down device 5 is to be placed relative to the relief drum 2 so that the rolls 6 would actually enclose uniformly the casing of the relief drum essentially over half the circumference that forms up the base of the cylinder defining the shape of the casing, i.e., would enclose the entire surface of the casing 3 located between its upper and lower parts as shown in Fig.2.
- the means 7 for removing the molded core is placed relative to the relief drum 2 so that the supplementary roll 29a would be arranged close to the lower part of the casing 3.
- the axles of the rolls 29 are parallel with the axis of rotation of the relief drum and, correspondingly, with the axles of the rolls 6 of the holding-down device 5 (Fig.2).
- the profile of the inner edge 21 of the central ring 20 is designed so that, at any angular position of the disk 14, the angle between the adjacent spokes is at its maximum within the upper part of the relief drum 2, whereas this angle is at its minimum within the lower part of the relief drum 2.
- the distance between the adjacent beams 10 attached to the spokes 13 and carrying the holders 12 of the casing 3 changes gradually, in the process of turning the disk 14 through one revolution, from its maximum within the upper part of the relief drum 2 to its minimum within the lower part of the relief drum 2 and then again to its maximum as this one revolution of the disk 14 is being completed.
- the plates 4 get gradually displaced inside the casing 3 arranged on the holders 12 in the tangential direction from the position, when they define an essentially smooth surface (within the upper part of the casing 3), to the position, when they define a corrugated surface with the maximum height of the crimps (within the lower part of the casing 3), and back again to the position, when they define an essentially smooth surface.
- the mutual displacement of the plates 4 takes place in the direction that is parallel with the axis of the shaft 15; in this case, the dependency of such displacement from the angle of rotation of the disk 14 is similar to the dependency of the mutual displacement of the plates in the tangential direction, which has been described herein above.
- the displacement of the plates in the axial direction takes place in the following way.
- each of the rollers 22 mounted on each one of the outermost sliding members 1 1 of every beam 10 is in contact with the surface of the corresponding side ring 25. Since the rings 25 are arrange on the immovable support having an inclination relative to the vertical plane, in which essentially lies the central ring, the rollers 22 of every beam 10 are periodically moving nearer to one another and then back away from one another during rotation of the disk 14. In doing so, the distance between the adjacent sliding members 1 1 of every beam 10, which carry the holders 12 of the casing 3, gets also changed, because these sliding members are interconnected with each other by means of the pantograph 23.
- the inclination of the side rings 25 is selected so that the maximum distance between the adjacent sliding members 1 1 would correspond to the maximum distance between the beams 10, whereas the minimum distance between the adjacent sliding members 1 1 - to the minimum distance between the beams 10.
- Prepreg is fed onto the upper part of the rotating relief drum 2 in the form of sheet material, which is pressed against the surface of the casing 3 by means of the roll 6 of the holding-down device 5.
- the value of adhesion is selected so that the sheet material 1 , when pressed against the casing 3 by the rolls 6, would not tear off from it, while the surface of the casing 3 is changed, thus repeating the shape thereof, but as soon as the relief drum is turned around through 180°, the corrugated sheet material 1 would detach from the surface of the casing 3 under the influence of its own weight.
- the corrugated sheet material 1 moves in the direction away from the relief drum, while being at first supported by the supplementary roll 29a of the means 7 for removing the molded core and subsequently entering into the clearance between the rolls 29 of the upper and lower rows of the means 7 for removing the molded core.
- the above- mentioned clearance is to be set at a predetermined value, so that when the molded core passes between the rolls 29, the height of its crimps gets calibrated.
- the sheet material can be fed to the relief drum both in the form of a continuous band or as separate predetermined cut-off lengths.
