Description

 The invention relates to the production of honeycomb core as a structural element of three-layer (multilayer) honeycomb panels and shells. The latter are used in almost all industries such as, for example, construction, furniture, aviation, space and rocket, automotive and others.

 The device is one of the main types of technological equipment and performs a number of technological operations in a sequential cycle of manufacturing cellular aggregates. It is at the beginning of the production line for their production.

 A device for the manufacture of packages of cellular aggregates of fiberglass (1), made in the form of sequentially located on the same unit for winding tissue from a roll, a roller for receiving material, an applicator unit, a unit for drying adhesive strips, a unit for winding fabric onto a frame, a unit for air drying glue .

 The fabric roll is installed in the center of the roll holder equipped with a braking device. Fiberglass wound from a roll enters the roller, along which a gluing unit is installed along the generatrix. The latter consists of a bathtub and ballpoint pencils fixed in the bottom of the bathtub. The number of pencils corresponds to the number of applied adhesive strips, the step of which is equal to the width of the four faces of the filler cells. In the working part of the pencils, balls protruding from the holes by about a quarter of a sphere are embedded. Balls are pressed against the seat saddles by springs. The fabric moving with respect to the fixed pencils rotates the balls. During rotation and indentation, the balls transfer glue from the cavities inside the pencils communicating with the bath to the fiberglass. With further movement, fiberglass with adhesive strips enters the heated plate in contact with the clean side. A honeycomb pack is formed when the fabric is wound on a tetrahedral frame. During winding, the final drying of the adhesive strips with hot air takes place. After each full turn of the frame, the applicator assembly is shifted by half a step, thereby achieving a checkerboard arrangement of adhesive strips in the section of the package. A frame with wound fabric is transferred to a slipway and bags are cut out for further technological operations.

 In the known device is time-consuming adjustment of the thickness and width of the adhesive strips. Adjustment is made with the movement of the fabric, increasing or decreasing the yield of glue from under the balls. Each pencil is adjusted separately by turning the nut, moving it up or down along the vertical axis.

 In addition, the manufacturing of cellular aggregate packages themselves is not directly ensured and special equipment is required to cut the package from the frame. This creates a large amount of waste.

 Also, it is not possible to obtain packages of honeycomb aggregates, the cells of which consist of three or more different materials, since only one material coming from only one roll can be used.

 It is not possible to obtain packages of honeycomb aggregates, the cell faces of which have the same thickness equal to two thicknesses of the starting materials. This machine makes packages of aggregates, in which two faces in the cell have a thickness equal to two thicknesses of the starting materials, and the remaining four faces have a single thickness of the starting roll material.

 Cellular aggregate packages with a combination of rectangular and hexagonal cells are not provided. The known machine is intended for the manufacture of either only hexagonal or only rectangular cells of the honeycomb core.

 Receiving packages of cellular aggregates with variable physico-mechanical and / or thermophysical characteristics over the area of the cellular aggregate is not ensured. Variability of the mechanical characteristics can be provided either by the variability of the shape of the cells, or by the variability of the materials used in the cells of the honeycomb core.

 A device is also known for the manufacture of paper honeycomb bags (1). It is an automatic machine for applying adhesive strips, drying them and wrapping a roll of paper on the frame. The device is made in the form of consecutively arranged knotting units of paper from a roll, an applicator unit, a unit for drying adhesive strips, a unit for winding paper onto a frame.

 The machine is equipped with a paper reeling unit from a roll with a diameter of up to 700 mm and a width of up to 750 mm. The node contains a braking device. Glue strips on a roll of paper are applied on one side. The unit for applying adhesive strips consists of a bath with adhesive solution and two gluing rollers with belts. The belts of one roller are offset relative to the other by half a step. The roller with belts is in contact with the roller placed in the adhesive solution. Adhesive strips are applied to the paper as it passes through a roller with belts moistened with glue. The distance between the belts on each roller corresponds to the step of the applied adhesive strips and is equal to four widths of the face of the filler cell. Paper with adhesive strips is passed through the glue drying unit, which is a camera with a battery of lamps installed on it. Paper with dried adhesive strips enters the winding unit, which is a square frame. After each revolution of the frame, the applicator rollers with belts change places. Due to this, in a roll of paper wound around the frame, adhesive strips in adjacent layers are obtained offset by half a step. A frame with wound paper is transferred to a slipway and packages are cut for further technological operations.

 This device has the same disadvantages as the above device.

 The closest technical solution to the claimed one is an Avro machine, the description and diagram of which is given in the above book, p. 161-162.

 The device is made in the form of successive first and second means for winding the material, two glue applicators with baths and rollers with belts spaced apart from each other by the step of the adhesive strips, a heating unit for drying the adhesive strips, rollers of the adhesive forming unit strips, a node for the formation of drainage holes, a cutting unit for folding the package and driving and guide shafts placed along the entire path of the material.

 The device is a two-roll automatic machine for the manufacture of honeycomb packs and is filled with non-fat rolls of aluminum foil. From the first roll, the foil, passing through the guide rollers, enters the glue applicator, where glue strips with protruding belts are applied to it from both sides. The belts of the roller located on one side of the foil are offset by half a step relative to the belts of the roller located on the other side of the foil. The glue is applied to the roller belts by other rollers immersed in glue baths. The applied adhesive strips are dried as the foil passes through the oven. Then the foil is sent to the drainage hole formation mechanism. The foil from another roll, but without adhesive strips, enters the same mechanism. Drainage holes are formed while the foil passes from two rolls through this mechanism. Holes are punched with needles attached to one of the rollers; the second pressure roller is rubber-protected. Drainage holes are punched on non-glued areas of the duplicated foil web and are rolled as the foil passes through two crimp rollers.

 The foil is cut into sheets of a certain length with the help of guillotine shears mounted on a bed of a machine. Cut sheets of foil are stacked in a stack in a stacker.

 The assembled bag is transferred to another section of the gluing workshop.

 This device does not provide the manufacture of packages of cellular aggregates, the cells of which consist of three or more different materials and have faces of the same thickness equal to two thicknesses of the starting materials, the production of cellular aggregates with a combination of rectangular and hexagonal cells, the manufacture of cellular aggregates with variables of physical and mechanical and / or thermophysical characteristics over its area.

 The device comprises first means 1 for winding aggregate material located in the process, first guide 2 for material, first adhesive unit 3, second guide 4 for material, second means 5 for winding aggregate material, third guide 6 for material, sheet forming unit 7 , a heating unit 8 to ensure complete curing of the adhesive strips, a second gluing unit 9, a heating unit 10 for drying the adhesive strips, a drainage forming unit 11 from ERSTU, cutting assembly 12, assembly 14 for folding the package and placed along the path of movement of the material, and several guide rollers 14. The filler material is indicated by numeral 15 and 16, a stepped leaf - pos. 17. The following is a more detailed description of the design of the device with reference to the drawings described in the description.

 The first means 1 for winding the material (Fig. 1) is designed to accommodate a sufficient amount of honeycomb core material and supply it to subsequent nodes to form honeycomb packets. It is made in the form of a cassette assembly, consisting of several coaxially arranged cassettes 18 (Fig. 2) with material tapes 16 (Fig. 1, 2) wound on them (metal, fabric, paper, etc.). The width of the tape, and therefore the width of the receiving groove of the cartridge is equal to the width of the three faces of the honeycomb core. The cassettes in the assembly are located so that the edges of the tapes in adjacent cassettes are spaced apart from each other by a distance equal to the width of the honeycomb core cell edge. Cassettes can be filled with tapes of material of the same brand, and tapes of various materials. Since the feed of the tape is accompanied by the accelerated rotation of the cartridge, which has a sufficiently large inertia, to prevent the formation of loops and breaks, as well as to constantly tension the tape, each cartridge is equipped with a braking device, the construction of which is known from similar nodes.

 Behind the first means 1 for winding the material is placed the first guide 2 (Fig. 1). It is intended for accurate fixation of the position of the material tapes before they enter the first glue-carrying unit 3 and directions to the corresponding sections of the latter. The guide 2 is made in the form of a comb with teeth 19 or a roller with grooves 20. The distance between the teeth 19 of the comb or the width of the grooves 20 on the roller is equal to the width of the material tapes wound on the cassettes of the first cassette assembly. The guide is located relative to the cassettes of the cartridge assembly so that its grooves or gaps between the teeth of the combs are located exactly opposite the material tapes in the respective cassettes of the first cassette means for winding the material. In this case, the gap between the teeth of the combs or between the grooves is equal to the four widths of the faces of the honeycomb core.

 Behind the first guide is the first applicator assembly 3 (FIG. 1 and FIG. 3). Its general design is known from similar devices. It consists of three rollers (Fig. 3). The first adhesive roll 21 is placed in the bath 22 with glue 23 and is in contact with the applicator roller 24. The latter, as a rule, is driven and rotates the entire system of rollers of the applicator assembly. It is equipped with protruding belts 26. For tight contact of the applicator roller with the honeycomb core material, the third upper roller 26 is equipped with a pressing device (spring, pneumatic or other), not shown in the drawing), which creates a pressing force P (Fig. 1). In the proposed device, the applicator roller differs from the known ones in that its belts 9 (Fig. 3) are arranged with a step equal to two widths of the faces of the honeycomb core and aligned with the edges of the material strips 16 (Fig. 3) coming from the first cartridge assembly.

 After the first applicator assembly, a second guide 4 is located (Fig. 1). It is designed to accurately fix the location of the material tapes with adhesive strips applied before entering the step formation sheet of the material. The design of the second guide is identical to the design of the first guide 2 (Fig. 1) and its location corresponds to the location of the first guide relative to the material tapes.

 The second means 5 for winding the material 17 (Fig. 1 and Fig. 2) are identical in purpose and design to the first means for winding the material. In this case, the cassettes 18 (Fig. 2) of the first cassette assembly are offset relative to the cassettes 27 (Fig. 2) of the second cassette assembly so that their tapes 16 overlap the material tapes 17 of the second cassette assembly to the width of the face of the filler cell.

 The third guide 6 (Fig. 1) is located after the second means 5 for winding the material and serves to accurately fix the position of the material tapes coming from the second means for winding the material into the node 7 for forming a stepped sheet. Its design is identical to the design of the first guide 2 (Fig. 1), and the location relative to the cassettes of the second cassette assembly is similar to the location of the first guide relative to the cassettes of the first cassette assembly. However, the location of the third guide 6 (FIG. 1 and FIG. 4) relative to the second guide 4 (FIG. 1 and FIG. 4) is such that the grooves 20 (FIG. 4) or the grooves between the teeth 12 of the combs of the third guide are offset relative to the grooves 20 ( Fig. 4) or grooves between the teeth 19 of the comb of the second guide so that the tapes 16 (Fig. 4) from the first cassette assembly overlap the material tapes 17 of the second cassette assembly to the width of the face of the filler cell. In this case, the first and second guides are located above the tapes of the first cassette unit, and the third - under the tapes of the second cassette unit (see Fig. 4).

 After the second and third guides in the proposed device is placed node 7 forming a stepped sheet of material (Fig. 1). It consists of two rollers - the upper 28 (Fig. 5) and the lower 29. The upper roller is equipped with a pneumatic or spring device (not shown in the drawing) that creates a pressure P (Fig. 1) of one roller to another. These devices are known and therefore not shown in the figures of structural schemes of devices of nodes. The lower roller 29 is driven and provided with a heater 30, which is placed inside it.

 Behind the assembly 7 of the formation of the stepped sheet of material is located the heating assembly 8 (Fig. 1). It is designed to completely cure the glue in a stepped sheet of material. Its design is similar to the known nodes of this purpose and does not need a detailed description.

 Behind the heating unit 8 is placed the second glueing unit 9 (Fig. 1 and 5). Its basic construction is similar to the construction of the first glue applicator assembly of the proposed installation. However, it differs from the first applicator assembly and the known ones in that the bands 31 (Fig. 6) of the applicator roller 24 are located opposite the middle of the lower tapes 16 (Fig. 6) of the stepped sheet 17 with a step equal to four widths of the faces of the filler cell. In this case, the node can be filled with a different brand of glue in comparison with the first gluing unit. This is typical for the production of, for example, paper honeycomb fillers, when the first gluing unit is filled with quick-drying glue, and the second is relatively slow-drying.

 After the second gluing unit 9, a heating unit 10 is located on the device (Fig. 1). It serves to dry the glue on the stepped sheet 17 (Fig. 1), which was applied to the second glue-carrying unit and is a metal sheet heated to a certain temperature, which is in contact with the surface of the stepped sheet, on which there are no adhesive strips. The design of such a device is known and does not require a detailed description.

 Behind the heating unit 10, a node 11 is placed for the formation of drainage holes (Fig. 1). Its basic design is similar to the known ones. The difference is that the needles for forming holes in the stepped sheet are placed on the roller along its circumference and with a step equal to two widths of the honeycomb core cell face, and are also located along the axes of the glued sections of the stepped sheet.

 After the site for the formation of drainage holes on the device is a trim unit 12 (Fig. 1). It is a well-known cutter that cuts off measuring sheets from a stepped sheet (Fig. 1) to form a honeycomb pack.

 The device ends with a node 13 for folding the honeycomb pack (Fig. 1). In it, the measuring sheets (Fig. 1) are stacked one on top of the other so that the material tapes that make up the stepped measuring sheet of one sheet coincide with the material tapes of adjacent measuring sheets. The design of this unit can be borrowed from the printing industry.

 In the case of the use of thick sheet materials (paper, cardboard, fabric, etc.) for the manufacture of honeycomb fillers, it is possible to ensure high precision assembly of the stepped sheet in node 7 (Fig. 1). To this end, one or both shafts of the step sheet forming unit 7 are provided with grooves 31, 32 (FIG. 7) equal to the width of the material tapes and the depth from 1/4 to 3-4 of the tape thickness. The grooves 31 of the upper roller and the grooves 32 of the lower roller are arranged in accordance with the pitch and arrangement of the respective material tapes.

 The claimed device is capable of producing packages of cellular placeholders with a combination of hexagonal and rectangular cells. To this end, the cassettes 18 of the first cassette assembly 1 with the material tapes 33 (Fig. 8) are located relative to each other from the side of the hexagonal cells so that the distance between the edges of the tapes is equal to the width of the hexagonal cell face, and from the side of the rectangular cells of the cassette 18 with the material tapes 34 (Fig. 8) are located relative to each other so that the distance between the edges of the tapes is equal to the width of the face of the rectangular cell. In this case, between the cassettes for tapes 33 and 34, forming hexagonal and rectangular cells, there is a cassette 35 (Fig. 8) with a tape of material 36 for the formation of transitional pentagonal cells. In the second cassette unit 5 (Fig. 1 of Fig. 8), the location of the cassettes 27 is similar to the location of the cassettes in the first cassette unit, but the distance between the edges of the tapes of two adjacent cassettes with material tapes for forming hexagonal 33 and rectangular 34 cells is equal to the width of the pentagonal cell face. In this case, the annular grooves 20 in the guide rollers 2, 4, 6 (Fig. 1) or the gaps between the teeth 19 of the combs, the rollers of the node 7 forming a stepped sheet (Fig. 1) and the girdles on the applicator rollers 25 (Fig. 3) and 37 of the fig . 6 are performed in steps corresponding to the location of the cassettes 18, 27, 35 (Fig. 8) with tapes, and the width of the bands 25 on the applicator rollers corresponds to the width of the faces of the respective cells.

 The device operates as follows.

 Cassette nodes 1, 5 (Fig. 1) are filled with cassettes 18 and 27 with tapes of a given material. The pressure rollers of the applicator assemblies 3, 9 (FIG. 1) and the assembly 7 for forming a stepped sheet (FIG. 1) are lifted until a clearance is necessary for filling the tapes. On the lower roller 29 (FIG. 5) of the assembly 7 for forming a stepped sheet of material of FIG. 1 a strip of adhesive tape (tape with glue) is applied. The tape of each cartridge is manually passed through the corresponding stream of the guide 2, 4, 6 (Fig. 1, 5) between the pressure 26 (Fig. 3) and the applicator 27 (Fig. 3) rollers of the first applicator assembly and is glued to the strip of adhesive tape. Thus, a non-glued stepped sheet is obtained. It is carefully passed between the pressure and guide rollers of the heating unit 8 (Fig. 1) and clamped with the necessary pressing pressure P on the second applicator unit 9 (Fig. 1). Previously raised pressure rollers return to their original position, adjust the necessary pressure. Glue 23 is poured into the baths 22 (Fig. 3, 6), the necessary heating means 30 are included (Fig. 5), the heating units 9 and 8 and 10 (Fig. 1), and after reaching the set temperature, they include the drive of movement of all the drive rollers on minimum speed. At the same time, in the first gluing unit 3 (Fig. 1), strips of glue 37 are applied (Figs. 3, 4, 5, 6, 7), which is cured previously or depending on the brand of glue almost completely in the node 7 to form a stepped sheet ( Fig. 1) and finally in the heating unit 8 (Fig. 1). After this, the stepped sheet 17 enters the second glue-carrying unit 9, where subsequent strips of glue 38 are applied to it (Fig. 6). They are dried to tack on the heating unit 10, the stepped sheet is perforated along the axis of the glued edges of the material tapes in the node 11 to form drainage holes (Fig. 1) and cut into measuring sheets of the same format (size) with a cutter in the cutting unit 12 (Fig. 1). Measured sheets are stacked in a stack in the specified manner and sent for gluing to a heated press (not shown). If the process is proceeding normally, then the speed of the tapes is increased to a predetermined value.

 Thus, honeycomb packs are obtained in which the cells have faces of the same thickness equal to two thicknesses of the starting materials and consist of three or more different materials, and honeycomb aggregates with a combination of rectangular and hexagonal cells and physical-mechanical and / or thermophysical variables are also obtained. characteristics of its area. In FIG. 10-11 shows a diagram of the products obtained on the proposed device. An analysis of these patterns shows that each cell forms eight bands of material. If each of the tapes will be made of different materials (metal foil, fabrics, paper of various grades), this can achieve all of the listed features that distinguish the products manufactured on the proposed device from the known.
