Description

Technical Field

[0001] The present invention relates to a fabric laminating mechanism used for creating a laminate by laminating a plurality of fabrics having patterns, a laminating table having the same, and a cutting device.

Background Art

[0002] [[ID=1l]] When manufacturing clothing, by cutting a laminate formed by laminating a plurality of fabrics, a plurality of identical parts are produced in a single cutting process, thereby improving the efficiency of the cutting operation. When the fabric is a patterned fabric having a pattern, pattern matching is performed between the parts constituting the clothing, so the parts obtained by cutting the laminate need to have the same pattern position relative to each other. For this reason, the fabrics constituting the laminate need to have the same pattern position relative to each other.

[0003] In order to meet such requirements, a stretching device for creating a laminate with the pattern positions of the fabrics aligned has been proposed in the past (see Patent Document 1). This stretching device includes a stretching table, a fabric base disposed on the stretching table, barbed needles fixed to the surface of the fabric base, a lifting frame provided on the stretching table, a fabric receiving plate supported by the lifting frame, a feeding table that travels on the stretching table to feed out the fabric, and a light marker that projects positioning light rays onto the fabric. The barbed needles are formed by standing needles on the surface of a seat plate, and are attracted to the stretching table by magnets provided on the back surface of the seat plate and fixed onto the fabric base.

[0004] The above fabric spreading device operates as follows: First, the piercing needles are positioned to coincide with the light rays from the light markers and fixed onto the fabric base. After this, the lifting frame is raised onto the spreading table, and a fabric receiving plate is placed on this lifting frame. The fabric receiving plate is placed with different width dimensions to correspond to different needle spacings depending on the arrangement of the piercing needles, so as not to interfere with the piercing needles. On this fabric receiving plate, the fabric fed from the feeding table is spread while being positioned by the light rays from the light markers. The spread fabric is fixed to the needles of the piercing needles that extend from below the fabric receiving plate. The spreading process is repeated to sequentially stack multiple layers of fabric, and as the thickness of the fabric stack increases, the lifting frame is lowered to maintain the amount of needle protrusion from the surface of the stack. When a predetermined number of layers of fabric have been stacked and the stack is complete, a pattern for the part is placed on the surface of the stack, and multiple holding needles are inserted into the stack from the surface of the pattern to fix the pattern and the fabric to each other. Next, the lifting frame is lowered below the surface of the fabric spreading table, the fabric receiving plate is removed, and the laminated material is cut. [Prior art documents] [Patent Documents]

[0005] [Patent Document 1] Japanese Patent Application Publication No. 7-011572 [Overview of the project] [Problems that the invention aims to solve]

[0006] However, the conventional fabric spreading device described above has the problem of having a complex configuration, as it includes a fabric receiving plate and a lifting frame that raises and lowers the fabric receiving plate. Furthermore, the fabric receiving plate must be selected and placed with different width dimensions to correspond to different needle spacings of the piercing needles, which makes the placement process time-consuming. Moreover, the conventional fabric spreading device has the problem of requiring many steps, such as placing the pattern, inserting multiple holding needles, lowering the lifting frame, and removing the fabric receiving plate, between the completion of the laminate and the cutting of the finished product.

[0007] Therefore, the object of the present invention is to provide a fabric lamination mechanism, a lamination table, and a cutting device that have a relatively simple device configuration and can create a laminated body by aligning the pattern of the fabric with relatively little effort. [Means for solving the problem]

[0008] To solve the above problems, the fabric lamination mechanism of the present invention is a fabric lamination mechanism used to create a laminate by laminating a plurality of fabrics having a pattern on a fabric lamination surface, A needle unit having a needle that pierces a second or more fabrics laminated on top of the first fabric, which is positioned on the surface of the first fabric placed on the fabric mounting surface, with alignment to characteristic points of the pattern of the fabric, A projector that projects and displays information onto the fabric mounting surface mentioned above, The above projector is equipped with a display control device that displays a guide indicating the position where the pattern of the fabric should be placed, and the area on the surface of the first fabric where the needle unit can be placed. It is characterized by having the following features.

[0009] According to the above configuration, the first fabric is placed on the fabric placement surface. Here, the first fabric is positioned in an appropriate location on the fabric placement surface by adjusting the pattern of the first fabric to match the guide displayed by a projector controlled by the display control device. Subsequently, the needle unit is positioned on the surface of the first fabric, aligned with the characteristic points of the fabric's pattern. The characteristic points of the pattern can be, for example, the edges of predetermined stripes if the pattern is a striped pattern, the intersections of predetermined grids if the pattern is a checkered pattern, or points identified by predetermined graphic elements or color elements if the pattern is a geometric pattern, a comma-shaped pattern, or a pattern of animals or plants. When the needle unit is positioned on the surface of the first fabric, based on the placeable area displayed by the projector controlled by the display control device, the needle unit is positioned in an area that does not interfere with the cutting operation when the laminate is cut later. A second fabric is placed on top of the first fabric on which the needle unit is positioned, and the position of the second fabric is adjusted so that the characteristic points of the pattern on the second fabric coincide with the needles of the needle unit. The second fabric is fixed to the needle unit by being pierced by the needles. If there are fabrics beyond the second fabric, the process of placing those fabrics on top of the previous fabrics, adjusting their position so that the characteristic points of the pattern coincide with the needles of the needle unit, and piercing them is repeated for the number of fabrics, thereby forming a laminate. In this way, by aligning the needle unit with the characteristic points of the pattern on the first fabric, and piercing the second or subsequent fabrics with the characteristic points of the pattern coincide with the needles of the needle unit, a laminate in which the patterns of the fabrics match is created. According to the fabric lamination mechanism of the present invention, since a lifting device and fabric receiving plate like those in conventional fabric spreading devices are not required, a laminate of fabric can be created with a simple device configuration. Furthermore, in the laminate created by this fabric lamination mechanism, the fabric is fixed by a needle unit, and since the needle unit is positioned in the above-mentioned placement area, cutting can be performed without interfering with the cutting operation. In addition, since this fabric lamination mechanism does not require the process of removing the fabric receiving plate as in conventional fabric spreading devices, the laminate can be cut quickly and with minimal effort after its creation.

[0010] In one embodiment of the fabric lamination mechanism, the needle unit is A base with a built-in magnet, A non-slip member provided on the lower surface of the base and for preventing slippage of the first fabric located below the base, The upper needle, which is the needle, is provided on the upper surface of the above base, A reference part is placed on the above base and is used to align the characteristic points of the pattern of the above fabric with the above upper needle. It is equipped with.

[0011] According to the above embodiment, by placing a magnetic material such as iron below the first fabric, a magnetic force acts between the magnet of the base and the magnetic material. Furthermore, the anti-slip member provided on the lower surface of the base prevents the first fabric from slipping. The magnet and the anti-slip member securely fix the needle unit on the first fabric. The second fabric or a larger fabric is pierced through the upper needle provided on the upper surface of the base. In addition, the upper needle can be easily and appropriately aligned with the characteristic points of the pattern on the first fabric based on the reference part.

[0012] One embodiment of the fabric lamination mechanism includes a plate-like body formed containing a magnetic material, which is positioned above the fabric placement surface and below the first fabric. The above-mentioned display control device displays the area in which the plate-shaped body can be placed using the above-mentioned projector.

[0013] According to the above embodiment, a plate-like body formed containing a magnetic material is placed above the fabric placement surface and below the first fabric. Here, the area in which the plate-like body can be placed is displayed on a projector by a display control device. This area in which the plate-like body can be placed is an area in which the plate-like body does not interfere with the cutting operation when the laminate is cut later. The plate-like body is placed within this area in which the plate-like body can be placed. Here, it is preferable that multiple plate-like bodies of different shapes and sizes be prepared in advance so that they can be appropriately selected according to the shape and size of the area in which the plate-like body can be placed. After this, the first fabric is placed on the plate-like body, and a needle unit is placed on the first fabric. The magnetic force generated between the magnet built into the base of the needle unit and the magnetic material of the plate-like body, and the anti-slip member provided on the lower surface of the base, stably fix the needle unit on the first fabric. By placing the plate-like body in the area in which the plate-like body can be placed displayed on the projector, the laminate formed on the plate-like body can be cut without the cutting operation being hindered.

[0014] One embodiment of the fabric lamination mechanism includes a plate-like body that is positioned below the fabric placement surface and is formed containing a magnetic material.

[0015] According to the above embodiment, a plate-like body formed containing a magnetic material is placed below the fabric placement surface, and a first piece of fabric is placed on the fabric placement surface. When a needle unit is placed on this first piece of fabric, a magnetic force is generated between the magnet built into the base of the needle unit and the plate-like body. This magnetic force, along with an anti-slip member provided on the lower surface of the base, stably fixes the needle unit on the first piece of fabric. The plate-like body can be incorporated, for example, into a stacking table or cutting device having the fabric placement surface.

[0016] In one embodiment of the fabric lamination mechanism, the anti-slip member of the needle unit is the lower needle that is inserted into the first fabric.

[0017] According to the above embodiment, the lower needles inserted into the first fabric effectively prevent slippage between the first fabric and the needle unit. Here, the number of lower needles can be any number, and their placement can be anywhere on the lower surface of the base. Furthermore, the lower needles may pierce and penetrate the first fabric.

[0018] In one embodiment of the fabric lamination mechanism, the anti-slip member of the needle unit is made of one of the following: sandpaper, velvet cloth, rubber, and resin.

[0019] According to the above embodiment, slippage between the first fabric and the needle unit is effectively prevented by an anti-slip member formed from one of the following: sandpaper, velvet cloth, rubber, and resin. Here, the anti-slip member may be provided on part or all of the lower surface of the base. The rubber may be either natural rubber or synthetic rubber. The resin is not particularly limited in composition as long as it is a resin that exerts frictional force against the first fabric and provides an anti-slip effect. Examples of resins include silicone resin and urethane. A slightly tacky, removable adhesive can also be used as the resin. The resin or rubber can be, for example, a sponge-like material. The anti-slip member formed from sandpaper or velvet cloth can be, for example, formed into multiple or single rectangles or circles when viewed from the bottom, but the shape is not particularly limited. The anti-slip member formed from rubber and resin can be, for example, formed into multiple or single layers, multiple dots, or multiple or single rectangles or circles when viewed from the bottom, but the shape is not particularly limited.

[0020] One embodiment of the fabric lamination mechanism includes a conveying device whose surface forms the fabric placement surface and which conveys the laminate created on this fabric placement surface.

[0021] According to the above embodiment, a conveying device for conveying a laminate is provided, and the surface of this conveying device forms a fabric placement surface. By creating a laminate on the fabric placement surface formed on the surface of the conveying device, after the laminate is created, this laminate can be quickly conveyed to a cutting device or the like. Here, as the conveying device, a belt conveyor, an air table that conveys by air blown out from the surface, or the like can be adopted.

[0022] The laminating table of the present invention has the above fabric laminating mechanism.

[0023] According to the above configuration, since it has the fabric laminating mechanism of the present invention, a laminating table that can create a laminate by aligning the patterns of fabrics with a relatively simple device configuration and with relatively little effort can be obtained.

[0024] The cutting device of the present invention has the above fabric laminating mechanism. [[ID= 13]]

[0025] According to the above configuration, since it has the fabric laminating mechanism of the present invention, a cutting device that can create a laminate by aligning the patterns of fabrics with a relatively simple device configuration and with relatively little effort and can cut the created laminate can be obtained.

[0027] The present invention will be described in detail below with reference to the illustrated embodiments.

[0028] Figure 1 is a perspective view showing a lamination table having a fabric lamination mechanism according to a first embodiment of the present invention, and a cutting device for cutting the laminate created on this lamination table.

[0029] The lamination stand 1 is used to create a laminate 3 by laminating multiple fabrics having patterns, aligning the positions of the patterns to match each other. The lamination stand 1 comprises a lamination stand body 4, a fabric placement surface 5 formed on the surface of the lamination stand body 4 on which the fabrics are placed, a projector 6 that shines light toward the fabric placement surface 5 to display information, and a PC (personal computer) 7 as a display control device that causes the projector 6 to display predetermined information.

[0030] The fabric placement surface 5 is installed on the surface of the stacking base body 4 and is formed on the surface of a moquette sheet in which pile fibers are planted in a base fabric. Here, a conveying device for moving the stacked bodies 3 may be installed on the stacking base body 4, and the surface of this conveying device may function as the fabric placement surface 5. As the conveying device, a conveyor in which the surface of the conveyor belt becomes the fabric placement surface, or an air table in which the surface becomes the fabric placement surface as described later can be used.

[0031] The projector 6 projects light toward the fabric mounting surface 5 and displays information on the surface of the fabric mounting surface 5 or on the surface of the sheet or fabric 23 placed on the fabric mounting surface 5 using the irradiated light. A commercially available projector can be used and consists of LCD (Liquid Crystal Display) type projectors, DLP (Digital Light Processing) type projectors, LCOS (Liquid Crystal on Silicon) type projectors, etc. The projector 6 displays information such as a cutting pattern 40 representing the shape of the parts obtained by cutting the fabric 23 or laminate 3, a guide 44 indicating the position where the pattern of the fabric 23 should be placed, a needle unit placement boundary line 42 indicating the area where the needle unit 10 can be placed, and a plate-like body placement boundary line 41 indicating the area where the plate-like body 25 can be placed.

[0032] PC7 is a computer device that has information processing resources such as a CPU and memory, and the ability to connect to a network, and is equipped with a large-capacity storage device such as an HDD (Hard Disk Drive) or SSD (Solid State Drive). PC7 is preferably configured using a commercially available notebook-type general-purpose computer, but it may also be configured using a desktop-type general-purpose computer or a workstation. In addition, the display control device may be an embedded computer installed in the stacking stand 1, in addition to a general-purpose computer. PC7 performs various processes as a display control device by having the CPU read and execute programs from memory as needed. PC7 also receives data that shows the shape and arrangement of parts obtained by cutting the stacking body 3, the guide 44, the needle unit arrangement boundary line 42, and the plate-like body arrangement boundary line 41. This input data is output to the projector 6, and the projector 6 projects the cutting pattern 40, guide 44, needle unit arrangement boundary line 42, and plate-like body arrangement boundary line 41 onto the fabric placement surface 5 and the fabric 23 for display. Here, the PC7 may perform calculations based on the shape and arrangement of the input parts to generate the needle unit placement boundary line 42 and the plate-like body placement boundary line 41, and output this data to the projector 6. Furthermore, if a conveyor is installed on the surface of the stacking table body 4, the PC7 may control the operation of the conveyor. Also, the projector 6 does not need to display all of the cutting pattern 40, the guide 44, the needle unit placement boundary line 42, and the plate-like body placement boundary line 41; it may select and display only the necessary information from this data as appropriate.

[0033] The fabric lamination mechanism of this embodiment is used to create a laminate 3 by laminating a plurality of patterned fabrics 23 on the fabric placement surface 5 of the lamination stand 1. This fabric lamination mechanism is composed of a needle unit 10 which is placed on the first fabric 23A and has needles that pierce the second or subsequent fabrics to fix the fabrics together, the projector 6, and the PC 7 which serves as the display control device.

[0034] The cutting device 2 comprises a cutting device body 30, carriage rails built into both sides of the cutting device body 30 in the direction in which the fabric 23 or laminate 3 is fed, carriages 31, 31 that travel along these carriage rails, a head rail 32 supported between these carriages 31, 31, and a cutter head 33 that houses a cutting blade for cutting the fabric and travels along the head rail 32. The surface of the cutting device body 30 is a fabric placement surface 34 on which the laminate 3 to be cut is placed. This cutting device 2 is controlled by a PC 35 as a cutting control device.

[0035] PC35 is a computer device that has information processing resources such as a CPU and memory, and the ability to connect to a network, and is equipped with a large-capacity storage device such as an HDD or SSD. PC35 is preferably configured using a commercially available notebook-type general-purpose computer, but it may also be configured using a desktop-type general-purpose computer or a workstation. In addition, the cutting control device may be an embedded computer installed in the cutting device 2, rather than a general-purpose computer. PC35 performs various processes as a cutting control device by having the CPU read and execute programs from memory as needed. PC35 is also configured to receive data for a cutting pattern 40 that indicates the shape and arrangement of parts obtained by cutting the fabric 23 or laminate 3. Based on this input data, it controls the position of the carriages 31, 31 and the cutter head 33, and the operation of the cutting blade in the cutter head 33, thereby cutting the fabric 23 or laminate 3 on the fabric placement surface 34.

[0036] Figure 2A is a perspective view showing the needle unit 10 that constitutes the fabric lamination mechanism of this embodiment, Figure 2B is a cross-sectional view of the needle unit 10, and Figure 2C is a bottom view of the needle unit 10. The needle unit 10 has a plate-shaped base body 12 with a magnet built in, a plurality of lower needles 13, 13, 13, ... arranged on the lower surface of the base body 12 as anti-slip members, and a single upper needle 14 arranged on the upper surface of the base body 12. The base body 12 is formed in a square shape in plan view, and a ring-shaped magnet 16 is arranged on the lower side. The base body 12 is made of plastic, and the magnet 16 is fitted into an annular recess formed on the lower side.

[0037] The lower needles 13 described above have a length sufficient to pierce one to two layers of fabric used to create the laminate with this needle unit 10. These lower needles 13 are fixed to the corners of the square base 12, and a total of four are installed. Here, the number of lower needles 13 is not limited to four; any number of needles may be installed.

[0038] The upper needle 14 described above has a length that is slightly longer than the thickness of the laminate formed by this needle unit 10. The upper needle 14 is aligned with the characteristic points of the pattern of the first fabric 23A by the reference part 18 described later. By aligning the upper needle 14 with the characteristic points of the second or subsequent fabrics 23B and piercing these second or subsequent fabrics 23B through the upper needle 14, the patterns of the fabrics 23 constituting the laminate coincide with each other. One upper needle 14 is positioned at the intersection of the diagonals of the base body 12 in a plan view.

[0039] The base body 12 has four edges that extend in the thickness direction and are located at the corners of the square in a plan view, which function as reference parts 18. The reference parts 18 are used to align the upper needle 14 with characteristic points of the pattern of the fabric forming the laminate. Here, the reference parts 18 may be ridges that are in contact with the bottom surface, in addition to the edges of the base body 12. The reference parts 18 may also be indicated by differences in material, or they may be emphasized by recesses or protrusions provided on the surface of the base body 12. The reference parts may also be provided at other locations on the base body 12, for example, they may be located in the center of the sides of the square base body 12 in a plan view. In this case, the reference parts may be indicated by markings made of paint. The reference parts may also be formed on the top surface or side surface of the base body 12, and their placement is not limited as long as it is on the periphery of the base body 12.

[0040] The base body 12 is preferably provided with a gripping portion for easily operating the stacking needle unit 10. The gripping portion can be formed by flanges that protrude outward from the upper edges of each side surface of the base body 12. Alternatively, the gripping portion may be formed by a plurality of protrusions or notches provided on the side surface of the base body 12.

[0041] The magnet 16 described above is made of a permanent magnet such as a ferrite magnet or a rare earth magnet, and is not limited to a ring shape; it may also be a disc shape, a rectangular shape, or other shapes. Furthermore, multiple magnets may be embedded in the base 12.

[0042] Furthermore, the base body 12 may be formed of a transparent material in part or in whole. For example, a transparent resin may be placed in the portion corresponding to the central hollow portion in a plan view of the magnet 16, and the upper needle 14 may be placed on the surface side of this resin to constitute the base body 12. This allows the pattern of the fabric underneath to be observed through the transparent resin, making it easy to align the upper needle 14 with the characteristic points of the pattern.

[0043] Furthermore, in addition to having a square shape in plan view, the base body 12 may also have a circular shape in plan view. When the base body is formed in a circular shape, the upper needle 14 is positioned at the center of the circle. It is also preferable that four reference parts be placed on the top or side surface at 90° intervals with respect to the center of the circular base body. These reference parts can be formed by applying paint in a dotted or linear pattern to the top or side surface. When the base body is formed in a circular shape, it is also preferable that the lower needles 13 be placed at 90° intervals with respect to the center of the base body 12. The lower needles 13 and the reference parts may also be positioned at the same angle to each other.

[0044] The needle unit 10 described above is used in combination with a plate-like body that is placed below the first fabric 23A. Figure 3 is a perspective view showing the plate-like body 25. The plate-like body is formed by including a magnetic plate made of a magnetic material and a covering member installed on the surface of this magnetic plate. The covering member has the function of preventing slippage for the first fabric 23A placed on the surface of the plate-like body and the function of integration by allowing the tip of the lower needle 13 of the needle unit 10 to penetrate. The plate-like body 25 of this embodiment has an iron plate 26 as a magnetic plate made of iron and a resin film 27 as a covering member installed on the surface of this iron plate 26. Here, the material of the magnetic plate of the plate-like body 25 is not limited to iron, but may be other magnetic materials such as nickel. In addition, the covering member may be made of rubber or the like in addition to resin, and the material is not limited as long as the lower needle 13 can penetrate it. Furthermore, if the anti-slip function for the first fabric A is important, the covering member may be made of silicone resin or urethane, or it may be made using a slightly tacky, re-peelable adhesive. The rubber or resin forming the covering member can be, for example, a sponge-like material. Furthermore, it is preferable that the covering member be positioned to cover the entire surface of the plate-like body. In addition to the rectangular shape shown in Figure 3, the plate-like body 25 is positioned inside the plate-like body arrangement boundary line 41 corresponding to the shape of the cutting pattern 40. Therefore, it is preferable to prepare various shapes and sizes of plate-like bodies 25 in advance, such as circles, squares, elongated rectangles, and triangles in plan view.

[0045] Figure 4 is a schematic plan view showing how the plate-like body arrangement boundary line 41 and the needle unit arrangement boundary line 42 are displayed by the projector 6 on the surface of the fabric placement surface 5 and the surface of the fabric 23 on the fabric placement surface 5. Figure 4 shows a cutting pattern 40 representing the shape of the parts obtained by cutting the fabric 23 and the laminate 3, and a cutting blade 37 and a fabric pressing member 38, which are part of the members that move along the cutting pattern 40 when the laminate 3 is cut by the cutting device 2. Figure 5 is a schematic cross-sectional view showing the positional relationship between the cutting blade 37 and the fabric pressing member 38, the plate-like body 25 and the needle unit 10 when cutting the laminate 3. In Figure 5, 22 is an underlay sheet placed on the fabric placement surface, and 36 is a resin bristle that forms on the surface of the fabric placement surface 34 of the cutting device 2, and is formed so that the tip of the cutting blade 37 can penetrate between the resin bristle 36 during cutting.

[0046] As shown in Figure 4, the plate-like body placement boundary line 41 is set to draw a line that is a predetermined margin distance inward from the cutting pattern 40 corresponding to the movement line of the cutting blade 37 in order to prevent interference between the cutting blade 37 and the plate-like body 25. The area inside this plate-like body placement boundary line 41 is the area in which the plate-like body can be placed. Here, as shown in Figure 5, the fabric pressing member 38 can pass over the plate-like body 25, so the plate-like body placement boundary line 41 and the fabric pressing member 38 can overlap in a plan view. On the other hand, as shown in Figure 4, the needle unit placement boundary line 42 is set to draw a line that is a distance equal to the dimensions of the fabric pressing member 38 plus a margin distance inward from the cutting pattern 40 corresponding to the movement line of the cutting blade 37 in order to prevent interference between the fabric pressing member 38 and the needle unit 10. Here, the needle unit placement boundary line 42 may be set to prevent interference between the needle unit 10 and other parts that move together with the cutting blade 37 during cutting. The area inside this needle unit placement boundary line 42 is the area where needle units can be placed.

[0047] Next, a method for creating a laminated body 3 of patterned fabric 23 using the lamination stand 1 having the fabric lamination mechanism of this embodiment will be described.

[0048] First, data for a cutting pattern 40 representing the shape and position to be cut for the fabric 23 on which the laminate 3 is to be made, and data relating to the pattern of this cutting pattern 40 are input to the PC7. Examples of data relating to the pattern of the cutting pattern 40 include the intersection points of the lines representing the cutting pattern 40 and the pattern of the fabric 23, and lines that cross the cutting pattern 40 and coincide with the lines that make up the pattern of the fabric 23. In addition, data for guides 44 corresponding to the pattern of the fabric 23, data for plate-like body placement boundary lines 41 corresponding to the cutting pattern 40, and data for needle unit placement boundary lines 42 corresponding to the cutting pattern 40 are input to the PC7. At this point, the PC7 may perform calculations using the input cutting pattern 40 data to calculate the needle unit placement boundary lines 42 and the plate-like body placement boundary lines 41.

[0049] Next, a base sheet 22 is placed on the fabric placement surface 5 of the lamination table 1. The base sheet 22 is used to easily discharge the laminated body 3 created on the lamination table 1 from the fabric placement surface 5 when moving it to the cutting device 2, etc., and can be made of paper, resin film, thin sheet, etc. Next, a cutting pattern 40 showing the shape and arrangement of parts obtained by cutting the fabric 23 of the laminated body 3, and a plate-like body placement boundary line 41 whose inner side is the area where the plate-like body 25 can be placed are displayed on the surface of the base sheet 22 using a projector 6. After this, the plate-like body 25 is placed on the surface of the base sheet 22 and inside the plate-like body placement boundary line 41. The plate-like body 25 is selected to have an appropriate shape and size depending on the shape of the plate-like body placement boundary line 41 and the position where the needle unit 10 is expected to be placed. The selected plate-like body 25 is placed so that the resin film 27 as a covering member faces upwards. Figure 6 is a plan view showing a cutting pattern 40 and a plate-shaped body placement boundary line 41 displayed on the surface of an underlay sheet 22 placed on the fabric placement surface 5 of the lamination table 1, with multiple plate-shaped bodies 25 placed in the plate-shaped body placement area inside the plate-shaped body placement boundary line 41. By placing the plate-shaped bodies 25 in the plate-shaped body placement area, it is possible to prevent the plate-shaped bodies 25 from obstructing the cutting process when the laminate 3 is cut by the cutting device 2.

[0050] Next, the first fabric 23A is placed on the underlay sheet 22 on which the plate-like body 25 is placed on its surface. On the surface of the first fabric 23A, the cutting pattern 40 and a guide 44 indicating the position where the pattern of the fabric 23 should be placed relative to the position of the cutting pattern 40 are displayed on the projector 6. The guide 44 consists of a vertical guide line 44A for aligning the vertical pattern of the fabric and a horizontal guide line 44B for aligning the horizontal pattern. The vertical and horizontal positions of the first fabric 23A are adjusted and distortions are corrected so that the pattern matches the guide 44. The guide 44 indicates the position where the pattern should be placed based on the pattern alignment performed on the parts obtained by cutting the fabric 23 that constitutes the laminate 3.

[0051] Next, multiple needle units 10 are placed on the first fabric 23A. At this time, a needle unit placement boundary line 42, which indicates the area on the inside where the needle units 10 can be placed, is displayed on the surface of the first fabric 23A using a projector 6. Multiple needle units 10 are placed inside this needle unit placement boundary line 42. The needle units 10 are positioned by aligning them with the characteristic points of the pattern of the first fabric 23A located on the plate-like body 12. If the pattern of the fabric 23A is a grid, the characteristic points can be set to the intersections of the grid. Here, if the pattern of the fabric is a striped pattern, the edges of the stripes can be used as the characteristic points of the fabric, and if it is a geometric pattern, a comma-shaped pattern, a plant or animal pattern, etc., predetermined graphic elements or color elements can be used. To align the needle unit 10 with the characteristic points of the pattern of the first fabric 23A, the needle unit 10 is placed above the first fabric 23A, and its position is adjusted so that the reference portion 18 of the base body 12 of the needle unit 10 coincides with the lines that constitute the grid of the pattern of the fabric 23A and form the intersections. This adjustment of the needle unit 10's position is performed so that two pairs of diagonally opposite reference portions 18 of the four reference portions 18 coincide with the two lines that intersect at the intersections of the grid in a plan view. By aligning the needle unit 10 in this way, in a plan view, the position of the upper needle 14 of the needle unit 10 coincides with the position of the characteristic points of the first fabric 23A. Once the alignment of the needle unit 10 is complete, the needle unit 10 is pressed toward the first fabric 23A, and the lower needle 13 of the needle unit 10 is inserted through the first fabric 23A, causing its tip to penetrate the resin film 27 of the plate-like body 25. In this way, the needle unit 10 is stably fixed on the first fabric 23A by the lower needle 13 piercing the first fabric 23A and inserting into the resin film 27, and by the magnetic force acting between the magnet 16 of the base body 12 and the iron plate 26 of the plate-shaped body 25.

[0052] Figure 7 is a schematic diagram showing a first fabric 23A placed on a base sheet 22 on the fabric placement surface 5 of the stacking table 1, with the guide 44, cutting pattern 40, and needle unit placement boundary line 42 displayed, and the needle unit 10 placed in the needle unit placement area inside the needle unit placement boundary line 42. By placing the needle unit 10 in the above needle unit placement area, it is possible to prevent the inconvenience of the needle unit 10 obstructing the cutting when the stacking body 3 is cut by the cutting device 2. Here, the needle unit 10 may be placed outside the cutting pattern 40, in an area that exceeds the distance from the lines constituting the cutting pattern 40 to the dimensions of the fabric pressing member 38 plus a margin distance. When the needle unit 10 is placed outside the cutting pattern 40, it is not necessary to place the plate-like body 25, as in the case of the needle unit 10 placed near the edge opposite to the edge where the projector 6 is placed in the plan view of Figure 7.

[0053] However, when the needle unit 10 is placed outside the cutting pattern 40, it is preferable to also place the plate-like body 25 outside the cutting pattern 40. In this case, it is preferable to draw a line outside the cutting pattern 40, separated by a predetermined margin, to set an outer boundary line for the plate-like body, and to place the plate-like body 25 outside this outer boundary line. The area outside the cutting pattern 40 of this outer boundary line for the plate-like body becomes the area where the plate-like body can be placed outside the cutting pattern 40. Alternatively, it is preferable to draw a line outside the cutting pattern 40, separated by a distance equal to the dimensions of the fabric pressing member 38 plus a margin, to set an outer boundary line for the needle unit, and to place the needle unit 10 outside this outer boundary line for the needle unit. The area outside the cutting pattern 40 of this outer boundary line for the needle unit becomes the area where the needle unit can be placed outside the cutting pattern 40.

[0054] Furthermore, the projector 6 does not need to display the cutting pattern 40 when displaying the plate-shaped body arrangement boundary line 41 on the surface of the underlay sheet 22 or when displaying the needle unit arrangement boundary line 42 on the surface of the first fabric 23A.

[0055] When multiple needle units 10,10,10,... are fixed onto the first fabric 23A, multiple fabrics 23B,23B,... are placed one by one on top of the first fabric 23A. When placing the second fabric 23B, it is placed on top of the first fabric 23A, where the upper needles 14,14,14,... of the multiple needle units 10,10,10,... have pierced through and protruded, so that the patterns of the two fabrics roughly coincide. In this way, the second fabric 23B is received by the tips of the multiple upper needles 14,14,14,... and the area around each upper needle 14 is formed into a cone shape. The operator pinches this cone-shaped part of the second fabric 23B with their fingers and adjusts the position of the cone-shaped part so that the upper needle 14 located at the tip of this cone-shaped part coincides with the characteristic points of the pattern of the second fabric 23B. For all needle units 10,10,10,..., the tip of the conical portion formed by the upper needle 14 is adjusted to coincide with the characteristic points of the pattern on the second fabric 23B. When the upper needles 14,14,14,... of all needle units 10,10,10,... coincide with the characteristic points of the pattern on the second fabric 23B, the second fabric 23B is pressed to pierce it with the upper needles 14. The surface of the second fabric 23B, where the characteristic points of the pattern have been pierced by the upper needles 14,14,14,... of the needle units 10,10,10,... is smoothed with the operator's hand or a squeegee, so that the positions of the patterns on the second fabric 23B and the first fabric 23A coincide. These steps are repeated to arrange multiple fabrics 23B,23B,23B,... on the surface of the first fabric 23A to form a laminate 3. The number of fabrics 23A, 23B, 23B, 23B, ... that form the laminate 3 is such that the tips of the upper needles 14, 14, 14, ... of the needle units 10, 10, 10, ... protrude from the surface of the topmost fabric 23B. In this way, by using the needle units 10, 10, 10, ..., the patterns of the fabrics 23A, 23B, 23B, 23B, ... can be easily aligned to create the laminate 3. Furthermore, by using the lamination table 1 having the fabric lamination mechanism of this embodiment, a lifting device and fabric receiving plate like those in conventional fabric spreading devices are unnecessary, so the laminate 3 can be created with a simple device configuration.Furthermore, in the laminate created by the lamination table 1 having the fabric lamination mechanism of this embodiment, the fabrics 23A and 23B are fixed by the needle unit 10, and the needle unit 10 is placed in the area where the needle unit 10 can be placed, as indicated by the needle unit placement boundary line 42. Therefore, cutting can be performed without interfering with the cutting operation of the cutting device 2, which will be described later. In addition, since this fabric lamination mechanism does not require the process of removing the fabric receiving plate as in conventional fabric spreading devices, the laminate can be cut quickly and with little effort after it has been created.

[0056] The laminated body 3 created on the lamination table 1 having the fabric lamination mechanism of this embodiment is cut along a cutting pattern 40 by a cutting device 2 adjacent to the lamination table 1. Once the creation of the laminated body 3 on the lamination table 1 is complete, the laminated body 3 is moved to the cutting device 2 together with the underlay sheet 22, the plate-like body 25, and the needle unit 10. The movement of the laminated body 3 to the cutting device 2 can be done by an operator manually pulling the underlay sheet 22. If a conveying device is installed on the lamination table 1, the laminated body 3 is moved to the cutting device 2 by this conveying device. The conveying device is preferably a belt conveyor or an air table installed on the top of the lamination table 1, and it is preferable that a fabric placement surface 5 is formed on the surface of these conveying devices. Here, in the laminate 3, the fabrics 23A, 23B, 23B, 23B, ... are fixed to each other by multiple needle units 10, 10, 10, ..., and the needle unit 10 is fixed to the first fabric 23A and the resin film 27 by the lower needle 14, and is also fixed to the iron plate 26 of the plate-like body 25 by the magnetic force of the magnet 16. As a result, the laminate 3 can be moved stably from the lamination table 1 to the cutting device 2 without any displacement of the fabrics 23A, 23B, 23B, 23B, ...

[0057] The laminated body 3, having moved to the cutting device 2, is placed on the fabric placement surface 34 of the cutting device body 30. As the laminated body 3 moves from the stacking table 1 to the cutting device 2, data for a cutting pattern 40, indicating the shape and arrangement of the parts obtained by cutting the laminated body 3, is input to the PC 35 of the cutting device 2. This data may be output from the PC 7 of the stacking table 1, or from other devices or storage devices. Once the data for the cutting pattern 40 is input to the PC 35, the position of the carriages 31, 31 and the cutter head 33 and the operation of the cutting blades are controlled based on this data, and the cutting of the laminated body 3 on the fabric placement surface 34 is performed. At this time, since the needle unit 10 is positioned in the area where the needle unit can be placed, the needle unit 10 does not interfere with the operation of the cutting member inside the cutter head 33. Specifically, the needle unit 10 does not come into contact with the fabric pressing member 38 inside the cutter head 33 and interfere with the cutting. Furthermore, since the plate-like body 25 is positioned within the plate-like body placement area, the plate-like body 25 does not interfere with the operation of the cutting member in the cutter head 33. Specifically, the plate-like body 25 does not come into contact with the cutting blade 37 in the cutter head 33 and interfere with cutting. Once the cutting of the laminated body 3 by the cutting device 2 is complete, parts cut along the cutting pattern 40 are obtained from the laminated body 3. In this laminated body 3, the fabrics 23A, 23B, 23B, 23B, ... are fixed to each other by the plate-like body 25 and the needle unit 10, so cutting can be performed without causing any displacement of the fabrics 23A, 23B, 23B, 23B, ... As a result, multiple parts with the same pattern position can be efficiently produced.

[0058] Figure 8 is a cross-sectional view showing the fabric lamination mechanism of the second embodiment, and is a cross-sectional view showing the case where a magnetic material is placed below the fabric placement surface. The fabric lamination mechanism of this embodiment is applied to a cutting device and is used to create a laminate of fabric on the fabric placement surface of the cutting device. In this embodiment, the same reference numerals are used for components similar to those of the first embodiment, and detailed descriptions are omitted.

[0059] As shown in Figure 8, the cutting device equipped with the fabric stacking mechanism of the second embodiment has a moquette sheet 47 on the upper surface of the cutting device body 30, which forms a fabric placement surface 34 on its surface. Below this moquette sheet 47, an iron plate 48 made of iron as a magnetic material is installed. This iron plate 48 is positioned over the entire lower surface of the moquette sheet 47. In the cutting device equipped with the fabric stacking mechanism of this embodiment, a projector 6 is installed above the cutting device body 30, which projects light onto the surface of the fabric placement surface 34 and the surface of the fabric 23 placed on the fabric placement surface 34 to display information. In other words, it has a configuration similar to the cutting device 2 of the first embodiment, but with an iron plate 46 built into the lower side of the fabric placement surface 34, and with the addition of the projector 6 and PC 7 of the stacking stand 1 of the first embodiment.

[0060] In the cutting device of the second embodiment, when creating a laminate 3 of fabric 23, the first fabric 23A is placed on the fabric mounting surface 34. On the surface of the first fabric 23A, the cutting pattern 40, guides 44, and needle unit placement boundary line 42 are displayed on the projector 6 under the control of the PC 7. In this embodiment, the plate-like body placement boundary line 41 is not displayed. In the area where the needle unit can be placed, indicated by the needle unit placement boundary line 42, the needle unit 10 is placed, as in the first embodiment, so that the upper needle 14 coincides with the characteristic points of the pattern of the first fabric 23A. When the needle unit 10 is placed on the first fabric 23A, the magnetic force generated between the magnet 16 of the needle unit 10 and the iron plate 46 on the lower side of the fabric mounting surface 34 stably fixes the needle unit 10 on the first fabric 23A. Furthermore, the lower needle 13 of the needle unit 10 penetrates the first fabric 23A and also inserts into the moquette sheet 47, thereby stably fixing the needle unit 10. After this, similar to the first embodiment, a second or more fabrics 23B are placed so that the characteristic points of the patterns of these fabrics 23B coincide with the upper needle 14 of the needle unit 10, and are inserted into the upper needle 14 to create the laminate 3. Once the laminate 3 is completed, the PC 35 controls the position of the carriages 31, 31 and the cutter head 33 and the operation of the cutting blades to cut the laminate 3 and cut along the cutting pattern 40.

[0061] According to the cutting device equipped with the fabric lamination mechanism of this embodiment, the plate-like body 25 as in the first embodiment is unnecessary, and the step of arranging the plate-like body 25 is unnecessary. Therefore, the laminated body 3 can be created in fewer steps than in the first embodiment.

[0062] Figures 9A to 9C show the needle unit used in the fabric lamination mechanism of the third embodiment of the present invention. Figure 9A is a perspective view of the needle unit 110 of the third embodiment, Figure 9B is a cross-sectional view of the needle unit 110, and Figure 9C is a bottom view of the needle unit 110. The needle unit 110 of the third embodiment differs from the needle unit 10 of the first embodiment in that the anti-slip member is made of sandpaper. In the third embodiment, the same reference numerals are used to describe parts that are the same as in the first embodiment.

[0063] The needle unit 110 of the third embodiment comprises a resin base 12 that is square in plan view, a ring-shaped magnet 16 embedded in the lower surface of the base 12, an upper needle 14 positioned on the upper surface of the base 12, and sandpaper 113 positioned on the lower surface of the base 12. Four edges located at the corners of the square in plan view of the base 12 and extending in the thickness direction function as reference sections 18.

[0064] The sandpaper 113 corresponds to the anti-slip member of the present invention and provides anti-slip properties to the first fabric placed on the underside of the needle unit 110. The sandpaper 113 is positioned to cover the entire underside of the base body 12. Preferably, the sandpaper 113 has a grit size between P50 and P500 as defined in JIS R 6010 "Grit Size of Abrasives for Abrasive Cloths and Papers", and is appropriately selected according to the type of the first fabric.

[0065] Herein, in the needle unit of other embodiments of the present invention, materials other than sandpaper 113 may be used as the anti-slip member. Examples of other anti-slip members include velvet cloth, rubber, and resin. The rubber may be either synthetic rubber or natural rubber. The resin is not particularly limited in composition as long as it is a resin that exerts frictional force against the first fabric and provides an anti-slip effect. Examples of resins include silicone resin and urethane. A slightly tacky, removable adhesive may also be used as the resin. The resin or rubber may also be sponge-like. The anti-slip member may be provided on the entire lower surface of the base body 12, or on a part of the lower surface of the base body 12. When the anti-slip member is formed from sandpaper or velvet cloth, for example, it may be formed in the shape of multiple or one rectangle or circle when viewed from the bottom of the base body 12. Furthermore, when the anti-slip member is made of rubber or resin, for example, it can be made of multiple or single layers, multiple dots, or multiple or single rectangles or circles when viewed from the bottom of the base 12, but the shape is not particularly limited. In addition, in the needle unit of other embodiments, the anti-slip member may be made of protrusions formed integrally with the base. In this case, four pyramidal protrusions can be installed on the lower surface of the base as anti-slip members. These pyramidal protrusions may be integrally molded with the base body, or they may be formed separately from the base body and bonded to the base body.

[0066] In the other embodiments described above, when sandpaper 113, velvet cloth, rubber, and resin are used as anti-slip members for the needle unit, the plate-shaped body used in combination with this needle unit can be made of sandpaper, velvet cloth, and rubber, in addition to the resin film 27, as a covering member installed on the surface of the iron plate 26 as a magnetic plate.

[0067] Figure 10 is a cross-sectional view showing a portion of a stacking table to which the dough stacking mechanism of the fourth embodiment of the present invention is applied. A conveying device is installed on the dough placement surface 5 of this stacking table, and this conveying device is formed by an air table. This air table is composed of a plurality of air outlets opening into the smoothly formed dough placement surface 5, a plurality of branch pipes 51, 51, 51, ... connected to these air outlets, a main pipe 52 connected to these branch pipes 51, and a blower connected to this main pipe 52. The stacking table of the fourth embodiment also includes a projector 6 and a PC7 similar to those of the stacking table of the first embodiment.

[0068] When creating the laminate 3 on the lamination table in Figure 10, a base sheet 22 is placed on the surface of the fabric placement surface 5. Next, the cutting pattern 40 and the plate-like body placement boundary line 41 are displayed on the surface of the base sheet 22 using a projector 6. After this, the plate-like body 25 is placed on the surface of the base sheet 22 and inside the plate-like body placement boundary line 41. The first fabric 23A is placed on the base sheet 22 with the plate-like body 25 on its surface, and the cutting pattern 40 and guide 44 are displayed on the surface of the first fabric 23A using a projector 6. The vertical and horizontal position of the first fabric 23A is adjusted and distortions are corrected so that the pattern matches the guide 44. After this, the needle unit placement boundary line 42 is displayed on the surface of the first fabric 23A using a projector 6, and multiple needle units 110 are placed inside the needle unit placement boundary line 42 and on the surface of the first fabric 23A. Next, the second fabric 23B is placed on top of the first fabric 23A, and the characteristic points of the pattern of this fabric 23B are aligned with the upper needle 14 of the needle unit 110, and this fabric 23B is pierced through the upper needle 14. This process of aligning the characteristic points of the pattern with the upper needle 14 of the needle unit 110 and piercing is repeated for multiple fabrics 23B to create a laminate 3. In this way, a laminate 3 is formed in which the positions of the patterns of fabrics 23A, 23B, and 23B coincide with each other.

[0069] The laminated body 3 formed on the lamination table equipped with the fabric lamination mechanism of this embodiment can be moved to an adjacent cutting device, etc., by an air table acting as a conveying device, as follows. When the air table is activated, the airflow generated by the blower is guided to the main pipe 52 as indicated by arrow A. The air guided to the main pipe 52 flows through the branch pipes 51 and is continuously blown out from multiple air outlets on the fabric placement surface 5. This airflow from the air outlets reduces friction between the fabric placement surface 5 and the underlay sheet 22, and the underlay sheet 22 and the laminated body 3 can be easily moved manually by the operator. Here, the needle unit 110 and the plate-like body 25 are stably fixed to the first fabric 23A by the frictional force of the sandpaper 113 acting as an anti-slip member, the magnetic force between the magnet 16 and the iron plate 26, and the frictional force of the resin film 27. As a result, the laminated body 3 can be easily moved by the air table acting as a conveying device with the fabrics 23A, 23B, 23B stably fixed to each other.

[0070] The laminated body 3 created on the lamination table in Figure 10 can be moved to the cutting device 2 in Figure 5 for cutting. Here, when the laminated body 3 is on the fabric placement surface 5 of the lamination table, it is transported by the air table of the lamination table, while when it is on the fabric placement surface 34 of the cutting device 2, it is transported by a transport device formed including the fabric placement surface 34. The transport device provided in the cutting device 2 can be made up of a conveyor formed by connecting multiple blocks of brushes, each having resin bristles 36 implanted in it. This conveyor is built into the upper part of the cutting device body 30 of the cutting device 2. The brush blocks extend in the width direction of the cutting device body 30 and are arranged in multiples in the depth direction and connected in a loop to form a conveyor belt. The brush blocks are provided with drive locking shafts at both ends in the width direction and inside the loop. The brush conveyor belt has sprockets located at both ends in the direction of travel, and the locking shafts are arranged to engage sequentially with them. The upper surface of the brush conveyor belt is exposed to the surface of the cutting device body 30, forming a fabric placement surface 34. This conveyor is driven by a motor that rotates a sprocket, which drives the brush conveyor belt. As a result, the fabric or laminate 3 placed on the fabric placement surface 34 on the surface of the brush is made movable in the depth direction of the cutting device body 30. By using such a conveying device, the laminate 3 created on the lamination table and conveyed on the air table can be easily moved to a predetermined position on the cutting device 2. Furthermore, if the length of the laminate 3 is longer in the depth direction than the fabric placement surface 34 of the cutting device 2, the laminate 3 can be divided into multiple parts, and cutting and moving can be performed sequentially for each part of the laminate 3.

[0071] In the first embodiment described above, a laminate 3 is created on a lamination table 1 equipped with a fabric lamination mechanism, and this laminate 3 is moved to a cutting device 2 adjacent to the lamination table 1 by human power or a conveying device, where it is cut. However, the cutting device 2 of the first embodiment may also be equipped with a fabric lamination mechanism. In this case, a projector 6 is installed above the cutting device body 30 of the cutting device 2, projecting light onto the surface of the fabric placement surface 34 or the surface of the fabric 23 placed on the fabric placement surface 34 to display information. Furthermore, the PC 35 of the cutting device 2 and the PC 7 of the lamination table 1 are integrated, and the integrated PC controls the projector 6 and the cutting device 2. When creating a laminate 3 of fabric 23 with this cutting device 2, the cutting pattern 40 and the plate-like body arrangement boundary line 41 are displayed on the fabric placement surface 34 by the projector 6. Next, a plate-like body 25 is placed inside the plate-like body placement boundary line 41, and then the first fabric 23A is placed on the fabric placement surface 34 on which the plate-like body 25 is placed. The cutting pattern 40 and guide 44 are displayed on the surface of the first fabric 23A using the projector 6, and the position of the first fabric 23A is adjusted and distortions are corrected so that the pattern matches the guide 44. Next, the needle unit placement boundary line 42 is displayed on the surface of the first fabric 23A using the projector 6, and a plurality of needle units 10 are placed inside this needle unit placement boundary line 42. These plurality of needle units 10 are positioned by aligning them with the characteristic points of the pattern of the first fabric 23A. After this, the second fabric 23B is placed on the first fabric 23A on which the needle units 10 are placed, and the fabric is pierced so that the characteristic points of the fabric 23B match the upper needles 14 of the needle units 10. By repeatedly aligning the characteristic points of a predetermined number of second fabrics 23B with the upper needle 14 and piercing them, a laminate 3 consisting of the first fabric 23A and a predetermined number of second fabrics 23B is completed. Once the laminate 3 is completed, the PC controls the position of the carriages 31, 31 and cutter head 33 and the movement of the cutting blades based on the data of the cutting pattern 40, and the laminate 3 on the fabric mounting surface 34 is cut. In this way, the cutting device 2 equipped with a fabric lamination mechanism can create and cut the laminate 3 on the fabric mounting surface 34, so that the lamination and cutting of the fabric 23 can be performed in a relatively small installation space.

[0072] In the first to fourth embodiments described above, the base body 12 of the needle unit 10, 110 had a square shape in plan view, but the base body 12 may have other shapes. For example, the base body 12 may have a circular shape in plan view. When the base body is formed in a circular shape, the upper needle 14 is positioned at the center of the circle. It is also preferable to position four reference parts on the top or side surface at 90° intervals with respect to the center of the circular base body. These reference parts can be formed by applying paint in a dotted or linear pattern to the top or side surface. When the base body is formed in a circular shape, it is also preferable to position the lower needle 13, which serves as an anti-slip member, at 90° intervals with respect to the center of the base body 12. The lower needle 13 and the reference parts may also be positioned at the same angle to each other. Furthermore, the shape of the base body 12 may be a polygon such as a pentagon, hexagon, heptagon, or octagon in plan view, in addition to a square or circle. Even when the base is polygonal, it is preferable to position the upper needle at the center of the base in a plan view, and to position the reference portion at the periphery at 90° angles with respect to the center of the base.

[0073] In the above embodiment, the needle units 10 and 110 have a magnet 16 and a lower needle 13 or sandpaper 113, but the magnet 16, lower needle 13, and sandpaper 113 are not required. That is, the needle unit only needs to have a needle that is positioned on the surface of the first fabric 23A in alignment with the characteristic points of the pattern and that pierces the second or higher fabric 23B. In this case, the lower plate-like bodies 25, 48, and 54 of the first fabric 23A are unnecessary, and the projector 6 only needs to display a guide indicating the position where the pattern of the fabric should be placed and the area on the surface of the first fabric where the needle unit can be placed.

[0074] The present invention is not limited to the embodiments described above, and many modifications are possible within the technical concept of the present invention by those with ordinary skill in the art. [Explanation of symbols]
