Description

Technical Field

[0001] This disclosure relates to a solid wood veneer capable of automatic wrapping, and a method and apparatus for manufacturing the same. Background Technology

[0002] Traditional automotive wood veneer is produced by pre-forming wood sheets onto decorative veneer wood, performing in-line injection molding (back-injection molding) on ​​the pre-formed wood sheets, trimming the ends of the injection-molded wood sheets, and then curling and coating the trimmed wood sheets.

[0003] This traditional solid wood veneer product can provide a solid wood surface with excellent visual and tactile appeal due to the application of back-side injection molding, but because it includes high-hardness solid wood attached to its injection-molded surface, it feels cheap to consumers when pressed.

[0004] Of course, some customers may find the veneer product too hard due to the high-hardness of the solid wood. However, this product may not satisfy customers who prefer a softer interior material. Summary of the Invention

[0005] This summary is provided to introduce, in a simplified form, a series of concepts that will be further described in the detailed description below. This summary is not intended to identify key or essential features of the claimed subject matter, nor is it intended to help determine the scope of the claimed subject matter.

[0006] Various implementation methods are provided to use side-slip core material to achieve undercutting to improve the adhesion between the solid wood sheet and the core material, and to use back-slip core material to achieve automatic wrapping of the solid wood sheet, thereby automating the process.

[0007] Various embodiments also relate to pressing equipment for vehicle crash pads that include solid wood sheets capable of providing elasticity while giving a visual impression similar to solid wood.

[0030] The advantages and features of this disclosure and its implementation methods will become apparent from the following detailed description of embodiments in conjunction with the accompanying drawings. However, this disclosure may be implemented in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of this disclosure to those skilled in the art. This disclosure should be defined based on the full content set forth in the appended claims. Furthermore, the terminology used herein is for the purpose of describing embodiments and is not intended to limit this disclosure. As used herein, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should be understood that when the terms “comprising” / “including” and their derivatives are used in the specification, they specify the presence of the described components, steps, operations, and / or elements, but do not exclude the presence or addition of one or more other components, steps, operations, and / or elements.

[0031] Figure 1 This is a reference view used to illustrate the automatically wrapping solid wood veneer according to this disclosure.

[0032] like Figure 1 As shown, the automatically wrapping solid wood veneer according to the first embodiment of this disclosure includes a wood layer 101, a mesh layer 102, and an elastic layer 103.

[0033] Wood layer 101 is a layer that gives the same visual impression as wood. Wood layer 101 preferably has a thickness of 0.1 t to 0.2 t and may have a wood grain formed by a sander.

[0034] The mesh layer 102 is laminated under the wood layer 101 to reinforce the board. Preferably, the mesh layer 102 has a thickness of 0.2t.

[0035] The elastic layer 103 is laminated beneath the mesh layer 102 to provide elasticity. The elastic layer 103 may be formed from polypropylene (PP) foam or thermoplastic polyolefin (TPO) foam. Preferably, the elastic layer 103 has a thickness of 1 t to 2 t.

[0036] According to a first embodiment of this disclosure, the solid wood veneer may further include a protective film 104 laminated onto the wood layer 101 to protect the wood layer. Preferably, the protective film 104 has a thickness of 0.1 t.

[0037] Figures 2A to 2E This is a reference view used to illustrate the process of manufacturing solid wood sheets according to the first embodiment of this disclosure.

[0038] In the solid wood sheet of the first embodiment of this disclosure, such as Figure 2A As shown, a mesh layer 102 is laminated under the wood layer 101, and then as follows: Figure 2B As shown, an elastic layer 103 is laminated beneath the grid layer 102. Figure 2C As shown, a protective film 104 can be laminated onto the wood layer 101 to protect the wood layer 101.

[0039] like Figure 2D As shown, the solid wood sheet 100 also includes a filament cross-pad 140 and a core material 150 disposed at its bottom. The filament cross-pad 140 is disposed in a portion of the vehicle table to cushion that area.

[0040] Thus, preferably, the filament cross-pad 140, disposed in one area of ​​the table, is laminated beneath the elastic layer 103. Preferably, the filament cross-pad 140 has a thickness of 2 to 5 tons and is applied to the entire area within 3 mm of the injection-molded end of the solid wood sheet that is touched by hand. The filament cross-pad 140 may be made of PP or TPO material, but is not limited to these.

[0041] The core material 150 is mounted on the vehicle table and preferably has a thickness of 0.3 t.

[0042] After the bonding operation of applying adhesive to the core material 150 immediately following the primer is performed, the filament cross-pad 140 is attached to the core material 150. This can be achieved using a diaphragm or by extrusion. After the additional bonding operation of applying adhesive to the top of the filament cross-pad 140 is performed, the wood layer 101, the mesh layer 102, the elastic layer 103, the filament cross-pad 140, and the protective film are pressed together using an extrusion clamp.

[0043] Thus, according to the embodiments of this disclosure, the solid wood sheet 100 constituting the vehicle table can feel the same as solid wood and provide a certain degree of cushioning when passengers touch the solid wood sheet.

[0044] The effects of this disclosure cannot be achieved in the conventional method of manufacturing solid wood sheets by injection molding. However, according to the first embodiment of this disclosure, by applying PP foam / TPO foam to the back of the wood, the elongation of the solid wood sheet can be supplemented and the surface quality of the solid wood sheet can be improved, and by applying a filament cross-padded material used for existing natural or artificial leather to the core material, the solid wood wrapped product can be made soft.

[0045] The solid wood sheet 100 includes a solid wood sheet body 110 formed to have the same shape as a solid wood product. The solid wood sheet 100 includes a plurality of solid wood sheet extrusion fixing ribs and wrapping fixing ribs formed on the exterior of the solid wood sheet body 110 to secure the solid wood sheet 100. The solid wood sheet extrusion fixing ribs are formed into a solid wood sheet fabric using a molding (cutting) machine.

[0046] Each extrusion retaining rib has a first retaining hole 121 for securing the solid wood sheet to the press during the preforming process. During the preforming process, the first retaining hole 121 is secured to a retaining pin on the press. The first retaining hole 121 may also be provided with a slot 122.

[0047] Therefore, during the preforming process, the fixing pin of the preforming press can move along the slot 122 in the first fixing hole 121, thereby preventing damage to the solid wood body.

[0048] Thus, when the first fixing hole 121 formed in the extrusion fixing rib of the solid wood sheet 100 is fixed to the fixing pin of the preforming press, the first fixing hole 121 can be opened when the preforming process is performed on the solid wood sheet 100, thereby preventing damage caused by the fixing of the solid wood sheet body 110 during the preforming process.

[0049] Next, during the wood pressing process, each wrapping fixing rib has a second fixing hole 131, which is formed by a hole-processing pin of the preforming press during the preforming process to fix the solid wood sheet to the pin of the pressing machine.

[0050] According to a first embodiment of this disclosure, the solid wood sheet 100 includes: a solid wood sheet body 110, which is formed by molding (cutting) solid wood sheet 100 fabric to have the same shape as a solid wood product; a plurality of solid wood sheet extrusion fixing ribs, each formed by molding (cutting) solid wood sheet 100 fabric outside the solid wood sheet body 110 to have a predetermined length, for fixing the solid wood sheet 100 during the preforming process; and a plurality of wrapping fixing ribs, each formed by molding (cutting) solid wood sheet 100 fabric outside the solid wood sheet body 110 to have a predetermined length, for fixing the solid wood sheet 100 during the extrusion process.

[0051] Each compression fixing rib has a first fixing hole 121, which is formed in a specific position by the elongation of solid wood.

[0052] Each package retaining rib has a second retaining hole 131, which is formed by a pin of the molding machine during the preforming process for inserting the retaining pin of the molding machine therein.

[0053] According to a first embodiment of the present disclosure, a wrapping board layer can be constructed that can perform a preforming process by using extrusion fixing ribs to fix solid wood sheets to a preforming press during a preforming process, and can perform an extrusion pressing process by forming a second fixing hole in each wrapping fixing rib required for the next extrusion process during the preforming process, and then fixing the solid wood sheets to the extrusion press.

[0054] Reference Figure 3This invention describes a pressing apparatus for a vehicle crash pad comprising solid wood sheets, according to a first embodiment of the present disclosure.

[0055] Figure 3 This is a view illustrating a pressing apparatus for a vehicle crash pad comprising solid wood sheets according to a first embodiment of the present disclosure.

[0056] like Figure 3 As shown, the pressing apparatus for a vehicle crash pad comprising solid wood sheet according to the first embodiment of the present disclosure includes a lower press 210, an upper press 220, a plurality of first sliders 212 and a plurality of second sliders 225.

[0057] The lower press 210 includes a carved section 211 disposed in the area where the product will be formed, and a support section 212 configured to support the upper press 220 when pressed against it. Each support section 212 has a fixing pin for securing the solid wood sheet 100.

[0058] The upper press 220 includes an embossing part 221 that corresponds to the engraving part 211 of the lower press 210.

[0059] During the extrusion process of the solid wood sheet 100, the first slider 212 is moved and fixed to maintain the shape of the embossed portion 211 of the lower press 210, thereby forming the embossed portion 211. After the extrusion process of the solid wood sheet 100, the first slider 212 presses the back side of the solid wood sheet 100 while rising along the embossed portion 221 of the upper press 220, and then moves laterally.

[0060] The second slider 225 is disposed in the upper press 220 so that the solid wood sheet 100 located on the carving section 211 is pressed together with the embossing section 221 of the upper press 220 during the extrusion process of the solid wood sheet 100.

[0061] During the wrapping process of the solid wood sheet 100, after the second slider 225 rises together with the upper press 220, the back of the solid wood sheet 100 is pressed by the first slider 212.

[0062] Next, as the second slider 225 falls, it presses the solid wood sheet 100 against the inner back of the core material 150, so that the solid wood sheet 100, which is bent inward toward the carving part 211, can wrap around the core material 150.

[0063] Thus, according to the first embodiment of this disclosure, solid wood products in which the solid wood sheets are wrapped around the core material can be automatically produced after the process of extruding pre-formed solid wood sheets into the core material is performed.

[0064] Reference Figures 4 to 7The process for a pressing apparatus for a vehicle crash pad comprising solid wood sheets, according to a first embodiment of the present disclosure, is described.

[0065] First, such as Figure 4 As shown, the pre-formed solid wood sheet 100 is placed on the lower press 210, and the core material 150 is temporarily attached to the upper press 220.

[0066] Next, as Figure 5 As shown, the upper press 220 is pressed against the lower press 210.

[0067] Next, as Figure 6 As shown, the upper press 220 moves upward, and the first slider 212 rises along the back of the solid wood sheet 100 and moves along the side of the solid wood sheet.

[0068] Next, as Figure 7 As shown, by lowering the second slider 225 provided in the upper press 220 to squeeze the solid wood sheet 100 located inside the carved part 211 of the lower press 210, the wrapping process of the solid wood sheet can be automatically performed using the slider.

[0069] In other words, the second slider 225 can press the solid wood sheet 100 against the inner back of the core material 150 while falling, so that the solid wood sheet 100, which is bent into the carving part 211, can be wrapped around the core material 150.

[0070] Reference Figures 8 to 11 This invention describes a pressing apparatus for a vehicle crash pad comprising solid wood sheets, according to a first embodiment of the present disclosure.

[0071] According to a first embodiment of the present invention, a pressing device for a vehicle crash pad comprising solid wood sheet includes a lower press 210, an upper press 220, a plurality of first sliders 212 and a plurality of third sliders 215.

[0072] The lower press 210 includes a carved section disposed in the area where the product will be formed, and a support 212 configured to support the upper press 220 when pressed against it. Each support 212 has a fixing protrusion 214 for securing the solid wood sheet 100.

[0073] The upper press 220 includes an embossing portion 221 corresponding to the carving portion 211 of the lower press 210.

[0074] During the extrusion process of the solid wood sheet, the first slider 212 is fixed to maintain the shape of the embossed portion 211 of the lower press 210. After the extrusion process of the solid wood sheet, the first slider 212 presses the back side of the solid wood sheet 100 while rising along the embossed portion 221 of the upper press 220, and then moves laterally.

[0075] During the extrusion process of the solid wood sheet, the third slider 215 is fixed to maintain the shape of the embossed portion 211 of the lower press 210. After the extrusion process of the solid wood sheet, the third slider 215 presses the back side of the solid wood sheet 100 while rising along the embossed portion 221 of the upper press 220, and then moves to the side of the solid wood sheet 100 to cut the portion of the solid wood sheet that deviates from the core material 150.

[0076] First, such as Figure 8 As shown, after the pre-formed solid wood sheet 100 is placed on the lower press 210, the core material 150 is temporarily attached to the upper press 220.

[0077] Next, as Figure 9 As shown, the upper press 220 is pressed against the lower press 210.

[0078] Next, as Figure 10 As shown, the upper press 220 moves upward and the first slider 212 rises along the back of the solid wood sheet 100 to press the solid wood sheet against the core material 150.

[0079] like Figure 11 As shown, after the solid wood sheet 100 is pressed against the core material 150, the third slider 215 cuts the portion of the solid wood sheet 100 that deviates from the core material 150 while moving inward.

[0080] Thus, in the first embodiment of this disclosure, a portion of the compressed solid wood sheet that deviates from the core material can be automatically undercut.

[0081] Reference Figures 12 to 20 This invention describes a pressing apparatus for a vehicle crash pad comprising solid wood sheets, according to a second embodiment of the present disclosure.

[0082] Figure 12 This is a view illustrating a pressing apparatus for a vehicle crash pad comprising solid wood sheets according to a second embodiment of the present disclosure.

[0083] like Figure 12 As shown, the pressing apparatus for a vehicle crash pad comprising solid wood sheet according to the second embodiment of the present disclosure includes a lower press 1210 and an upper press 1220.

[0084] The lower press 1210 includes a carved section 1211 disposed in the area where the product will be formed, and a support section 1212 configured to support the upper press 1220 when pressed against it. Each support section 1212 has a retaining pin 1213 for securing the solid wood sheet 100.

[0085] The upper press 1220 includes an embossing portion 1221 corresponding to the engraving portion 1211 of the lower press 1210, and a first slider 1222 that moves in the embossing portion 1221 to adjust the width of the embossing portion 1221.

[0086] The lower press 1210 also includes a second slider configured to press the back side of the solid wood sheet 100 while rising along the core material 150 joined to the upper press 1220 during the extrusion process of the solid wood sheet 100.

[0087] After the extrusion process of the solid wood sheet, the first slider 1222 rises together with the upper press 1220.

[0088] Next, during the wrapping process of the solid wood sheet, the first slider 1222 moves downward to press the embossing part 1221 of the upper press 1220 while pressing the inner back of the core material 150, so that after the back of the solid wood sheet 100 is pressed by the second slider 1212, the solid wood sheet 100, which is bent inward to the carving part 1211, can be wrapped around the core material 150.

[0089] The lower press 1210 includes a carved section 1211 disposed in the area where the product will be formed, and a support section 1212 configured to support the upper press 1220 when pressed against it. Each support section 1212 has a retaining pin 1213 for securing the solid wood sheet 100.

[0090] The pressing device may also include a plurality of third sliders 1215, which are fixed to maintain the shape of the embossed portion 1211 of the lower pressed part 1210 during the extrusion process of the solid wood sheet. After the extrusion process of the solid wood sheet, the third sliders 1215 press the back side of the solid wood sheet 100 while rising along the embossed portion 1221 of the upper press 1220, and then move laterally to remove the remaining portion of the solid wood sheet.

[0091] In the following text, reference will be made to Figure 22 A method for pressing a vehicle crash pad comprising solid wood sheets according to a third embodiment of the present disclosure is described.

[0092] First, after the embossing portion 1221 of the upper press 1220 is formed by moving the first slider 1222 in the embossing portion 1221 of the upper press 1220 to correspond to the width of the embossing portion 1221 of the upper press 1220, a preforming process (S1310) is performed.

[0093] Next, by moving the first slider 1222 located in the embossing section 1221, the core material 150 can be attached to the embossing section 1221 of the press 1220, and then the core material 150 is temporarily bonded to the embossing section 1221 to perform the extrusion process (S1320).

[0094] In the following text, reference will be made to Figure 23 Describe the steps for performing the preforming process (S1310).

[0095] First, such as Figure 12 As shown, the first slider 1222, which is provided in the embossing part 1221 of the upper press 1220, is moved to correspond to the width of the carving part 1211 of the lower press 1210 (S1311).

[0096] Next, the fixing pin 1213 provided on the second slider 1212 of the lower press 1210 is inserted into the first fixing hole formed in the extrusion fixing rib of the solid wood sheet 100 to place the solid wood sheet 100 on the lower press 1210 (S1312).

[0097] Next, as Figure 13 As shown, solid wood sheet 100 is preformed by pressing the upper press 1220 into the lower press 1210 (S1313).

[0098] Next, after 100 pre-formed solid wood sheets, as... Figure 14 As shown, a second fixing hole (S1314) is formed in a plurality of wrapping fixing ribs provided in the solid wood sheet 100 by means of a processing pin provided in the second slider 1212.

[0099] In the following text, reference will be made to Figure 24 The detailed process of performing the extrusion process according to the third embodiment of this disclosure (S1320) is described.

[0100] First, such as Figure 15 As shown, after the preforming process is performed by extruding the solid wood sheet 100 via the lower press 1210, the first slider 1222 is moved inward while the upper press 1220 is moved upward (S1321).

[0101] Next, as Figure 16 As shown, the core material 150 is bonded to the embossing portion 1221 of the upper press 1220 (S1322).

[0102] Next, as Figure 17 As shown, the upper press 1220, having a core material 150 joined thereto, moves downward toward the lower press 1210 on which the pre-formed solid wood sheet 100 is placed, such that the lower press 1210 is pressed against the upper press 1220, as... Figure 18As shown in (S1323).
