Description

Technical Field

[0001] The present invention relates to a method for embroidering a continuous tape using an embroidery machine, according to the present invention. Background Technology

[0002] DE 19 923 912 A1 describes an apparatus and method for embroidering a continuous strip using an embroidery machine. As a result of the processing described herein, an embroidered strip is formed, in which a person's name is embroidered in a portion, for example. Badges and borders can also be additionally embroidered onto such embroidered names to achieve a specific representation of the section. Hereinafter, for simplicity, the term "embroidered name" will be used only, which also refers to feasible designs for sections with other embroidered elements (e.g., badges and borders).

[0003] This continuous embroidered strip is then separated in subsequent processing steps, resulting in individually operable strip segments, each bearing a name embroidered on it. Strip segments embroidered with names are commonly used for personalizing clothing, such as coats or work uniforms.

[0004] If an embroidered ribbon section is sewn directly to a coat or work uniform, for example, in the area of ​​a breast pocket, the coat or work uniform is precisely designed for the person using that name. This is generally undesirable for washing the coat or work uniform, and instead, it is preferable to use hook and loop fasteners or adhesive tape to attach the embroidered ribbon section only to the area of ​​the breast pocket of the coat or work uniform. For this purpose, hook and loop fasteners must be applied to the back of the ribbon section, and a felt section must be applied accordingly to the attachment area on the breast pocket.

[0005] If the strap section is double-layered directly during embroidery—that is, the upper strap (the visible side) and the lower strap (the hook and loop fastener) are embroidered together—the properties for attaching the hook and loop fastener will be compromised by the embroidered name, resulting in unreliable attachment. Accordingly, in the first step, it is necessary to embroider the name on the upper strap and then separate the strap section, and in another step, connect the upper and lower straps (the hook and loop fastener) via a circumferential seam. This seam only slightly impairs the hook and loop fastener's attachment ability, ensuring reliable attachment. Currently, this seam is a process performed by hand by a tailor, producing the finished strap section.

[0006] An embroidery frame for continuous embroidery of a material strip is known from DD 230 715 A3, by means of which the material strip is threaded and embroidered in single or multiple layers (e.g., from roller to roller), wherein the embroidery frame is constructed to coordinate the movement of multiple transport rollers with each other and to ensure braking of the material strip opposite to the main processing direction. Summary of the Invention

[0007] The purpose of this invention is to eliminate the aforementioned disadvantages and create a method by which automation is achieved when sewing an upper strap and a lower strap (e.g., hook and loop fastener) together using an embroidery machine or a sewing machine.

[0008] According to the invention, the above-mentioned objectives are achieved by combining characteristic features. Advantageous designs and improvements of the method according to the invention are described in the dependent claims. Attached Figure Description

[0023] Such as including but not limited to Figure 1 As can be seen, the method according to the invention first includes the following steps: a) guiding at least one upper band 3 section 30 to the embroidery area 207 of the embroidery frame 200; b) introducing embroidery onto the upper band 3 section 30 within the embroidery area 207 of the embroidery frame 200 by means of at least one embroidery head 101; wherein, the method according to the invention is characterized by the following additional steps: c) guiding at least one lower band 4 to the embroidery area 207 of the embroidery frame 200, the lower band being positioned below the upper band 3; d) creating at least one connecting seam between the upper band 3 and the lower band 4 in the plane E of the embroidery frame 200; e) removing the finished band 6 consisting of the embroidered band 3 and the lower band 4 sewn to it.

[0024] In another advantageous embodiment of the method according to the invention, the following steps are additionally provided: a) guiding at least one additional upper band to the embroidery area 207 of the embroidery frame 200, the additional upper band being placed on top of the upper band 3; b) creating at least one connecting seam between the upper band 3 and the additional upper band; and c) removing the finished band 6 consisting of the embroidered band 3 and the additional upper band sewn to it.

[0025] As from Figure 1 As can be seen, here, the lower band 4 and / or the other upper band can be guided to the embroidery area 207 in the opposite direction ER to the guiding direction FR of the upper band 3.

[0026] Furthermore, it is advantageous that the lower belt 4 and / or the additional upper belt are guided to the upper belt 3 by means of at least one conveying mechanism 206 (or slider) configured to be able to displace parallel to the plane E of the embroidery frame 200. Figure 1 ).

[0027] A particularly advantageous embodiment of the invention proposes that the lower tape 4 and / or additional upper tape and finished tape 6 are aligned and / or guided relative to the plane E of the embroidery frame 200, thereby guiding the conveyor 206 to its starting position A by means of the thrust acting on the conveyor 206 by the lower tape 4 and / or additional upper tape while the finished tape 6 is removed, so as to repeatedly guide the lower tape 4 and / or additional upper tape to the embroidery area 207.

[0028] As from Figures 1 to 8As can be seen, the present invention also includes an embroidery frame 200 for an embroidery machine, the embroidery machine being used to embroider a continuous tape 1 in the plane E of the embroidery area 207 of the embroidery frame 200 to perform the method according to the invention. The embroidery frame is characterized in that it includes at least one conveying mechanism 206 arranged in a manner that allows it to be displaced parallel to the plane E of the embroidery frame 200, by means of which the lower tape 4 and / or another upper tape are guided to the upper tape 3.

[0029] In a particularly advantageous embodiment (not shown), the embroidery frame includes a plurality of conveying mechanisms 206 arranged in such a way that they can be displaced parallel to the plane E of the embroidery frame 200, by means of which additional lower tapes 4 and / or additional upper tapes are sequentially guided above and / or below upper tapes 3 for sewing tapes to further embroider the tapes.

[0030] The embroidery frame 200 is advantageously capable of including, in any case, a base plate 2000 for housing and / or forming the embroidery frame 200, wherein at least one cut 2070 is provided in the base plate to form an embroidery area 207, such that the upper band 3 to be embroidered is guided from one side to the other at or through the cut 2070 for embroidery by means of the embroidery head 101 of the embroidery machine.

[0031] Preferably, at least one holding mechanism, fixing mechanism and / or clamping mechanism 202, 203 and at least one drive element 204a, 204b, 205a, 205b for the upper belt 3 are provided on at least one side of the embroidery area 207.

[0032] The conveying mechanism 206 may preferably include at least one driver 201.

[0033] As from Figures 1 to 8 As can be seen, the present invention also includes an embroidery machine 100, which is used to embroider a continuous tape 1 in the plane E of the embroidery area 207 of the embroidery frame 200 to perform the method according to the present invention. The embroidery machine is characterized in that it includes at least one unwinding roller 102 for the upper tape 3, at least one unwinding roller 103 for the lower tape 4, and at least one winding roller 104 for the finished tape 6.

[0034] In another embodiment of the invention, the embroidery machine 100 preferably includes at least one controller by means of which the embroidery frame 200 is moved at or on the plate 105 of the embroidery machine 100 in the X and Y directions during the embroidery and sewing processes, such that the embroidery is formed on the upper belt 3 by means of the embroidery head 101.

[0035] Figure 9 Showing continuous band 1, the continuous band has the name 2 embroidered in a partial area. And... Figure 11The diagram shows a single tape segment, which consists of a visible upper tape 3, an embroidered name 2, and a backing lower tape 4, preferably a hook-and-loop fastener. The connection between the upper tape 3 and the lower tape 4 can advantageously be achieved through a surrounding connecting seam 5. Correspondingly, the embroidered tape 6, sewn to the surrounding connecting seam, is... Figure 11 As shown in the image.

[0036] According to the invention and advantageously, the process is automated using an embroidery frame 200 at an embroidery machine or sewing machine. For this purpose, in Figure 1 The image shows an embroidery machine 100 with a selective embroidery frame 200. The (selective) embroidery frame 200 is located on a plate 105 of the embroidery machine 100 and is moved in the X and Y directions by the controller of the embroidery machine during the embroidery and sewing processes, so that the name to be embroidered on the belt 3 is formed by introducing the embroidery with the help of the embroidery head 101 and the free arm 107.

[0037] The embroidery machine 100 is preferably a free-arm embroidery machine, and accordingly has a free arm 107. This free arm ensures that the bobbin thread holder required for the embroidery process can be freely accessed from the front and sides. This configuration of the embroidery machine 100 is similar to that of a free-arm sewing machine. The required free access from the front and sides can also be achieved via other configurations in the bobbin thread holder area.

[0038] Figure 1 Also shown are unwinding rollers 102 for the upper belt 3 and 103 for the lower belt 4. The unwinding rollers 102 and 103 can be configured as loose rollers or driven rollers. The winding roller 104 is used to receive the finished belt 6 sewn according to the invention and advantageously has a drive unit.

[0039] Figure 2 and Figure 3 Details of the plate 105 of the embroidery machine 100 are shown. Free access to the free arm 107 from the front and sides is achieved via a cut 106 in the plate 105.

[0040] from Figure 4 The diagram shows a top view of the structure of an embroidery frame 200 according to the invention. The base plate 2000 of the embroidery frame 200 has a slit 2070 through which the tape 3 to be embroidered is guided from one side to the other, so that embroidery can be performed by means of the embroidery head 101 of the embroidery machine 100. A holding mechanism, fixing mechanism, and / or clamping mechanism 202 for the upper tape is mounted on the base plate 2000 of the embroidery frame 200 with associated drive elements 204a and 204b. A holding mechanism, fixing mechanism, and / or clamping mechanism 203 for the sewn tape is mounted on the other side of the slit 2070 with drive elements 205a and 205b. A drive 201 is used to move the conveying mechanism 206 according to the invention on the underside of the embroidery frame, as shown in the diagram. Figure 6As shown.

[0041] Figure 5b An embroidery machine 100 with an embroidery frame 200 for embroidering an upper tape is shown in a view from the front and the right end of the conveyor mechanism 206. The upper tape 3 is positioned on the left side of the embroidery frame 200, following the path of the unwinding roller 102 for the upper tape. The conveying of the lower tape 4 from the unwinding roller 103 is also shown. Due to the right end position occupied by the conveyor mechanism 206, the lower tape 4 is positioned on the right side of the free arm 107 and the name is not embroidered at this stage. Above the plate 105, on the right side, the finished tape 6, after embroidery and sewing, is guided from the embroidery frame 200 to the winding roller 104 for sewing the finished tape 6.

[0042] In contrast, Figure 5a The image shows an embroidery machine 100 with an embroidery frame 200 in the second stage of processing. Here, the conveyor mechanism 206 is in the left end position and the lower tape 4 is moved into the cutout 2070 and then to the left of the free arm 107. Thus, in the second stage of processing, the upper tape 3, which has already been embroidered with a name, is sewn together with the lower tape 4 by means of a surrounding connecting seam 5, the lower tape being positioned below the upper tape 3.

[0043] Figure 6 , Figure 7 , Figure 8 These figures, used to illustrate the position of the conveyor mechanism 206, show the embroidery frame 200 and the belt in different positions within the conveyor member 206 from a bottom view. Figure 6 The image shows the conveyor mechanism 206 in its right-hand end position. Correspondingly, the lower belt 4 is located on the upper right side, as it is in... Figure 4 The middle section is visible in the front view. Therefore, in this stage, only the upper band 3 is located in the cutout 2070 of the embroidery frame 200. Thus, according to the invention, only the upper band 3 is located below the embroidery head 101 and has the name embroidered in the first stage. After the name is embroidered on the upper band 3, the conveying mechanism 206 is moved to the left by activating the drive 201 for the conveying mechanism 206. Here, the lower band 4 is introduced into the cutout 2070 below the upper band 3. Figure 8 The conveyor mechanism 206 is shown in its left-end position. Thus, the lower belt 4 is introduced into the cutout 2070 completely below the upper belt 3. The lower belt 4 is located on the left side of the free arm 107, as it is... Figure 5a The middle section is visible in the front view. In this arrangement where the two belts 3 and 4 overlap each other, the circumferential connecting seam 5 is attached by means of the embroidery head 101 during the second stage of processing. After the circumferential connecting seam 5 is completed, at the end of the second stage, the conveyor mechanism 206 moves to its end position to the right, thereby releasing the lower belt again.

[0044] The operation of the invention will now be explained in more detail with reference to the flowchart. Method step a) establishes the initial state. For this purpose, the selective embroidery frame 200 is in the X / Y initial position, such that the cut 2070 is positioned before the free arm 107 in the area of ​​the cut 106. The upper belt 3 is guided from the unwinding roller 102 for the upper belt to the upper side of the embroidery frame 200, and with the left clamp 202 open, is guided from left to right via the cut 2070 to the equally open right clamp 203. In this initial state, the conveying mechanism 206 is in its right-side end position. The lower belt 4 converges with the upper belt from the lower unwinding roller 103 via the right clamp 203 from the lower side. Thus, the lower belt 4 is located to the right of the free arm 107. The upper and lower belts are guided together from the right clamp 203 to the winding roller 104 and secured thereto. The clamps 202 and 203 are closed by means of the driver 204 or 205. Then, the upper band 3, the lower band 4, and the converging band 6 are relaxed, thereby forming relaxations that allow the selective embroidery frame 200 to move in the X and Y directions, respectively.

[0045] In step b), the embroidery frame 200 travels along the Y direction below the embroidery head 101, allowing the tape inserted into the cut 2070 to be embroidered. Due to the preparation in step a, only the upper tape 3 is positioned in the cut 2070 for embroidery. The lower tape 4 is positioned to the right of the free arm 107, and therefore cannot be embroidered in the first stage.

[0046] In step b), the embroidery name is added and the process ends in step d. In step e, the selective embroidery frame is moved to the front X / Y position, such that the cut 2070 is positioned before the free arm 107 in the area of ​​the cut 106.

[0047] According to the invention, in method step c), the conveying mechanism 206 travels from its right end position to its left end position (driven by the driver 201). Here, the lower belt 4 is introduced into the cutout 2070 below the upper belt 3. Thus, the lower belt 4 is located on the left side of the free arm 107.

[0048] Then, the embroidery frame 200 travels along the Y direction below the embroidery head 101. In the next method step d), a circumferential connecting seam 5 is created between the upper tape 3 and the lower tape 4 using the embroidery head 101. After completing the circumferential connecting seam 5, the selective embroidery frame travels back to its X / Y starting position. The conveyor mechanism 206 travels to its right end position driven by the driver 201 and releases the sewn tape 6.

[0049] In the next processing step e), the holding mechanism, fixing mechanism, and / or clamping mechanism 202 and 203 are released. The embroidered and sewn tape 6 is fed and wound from the area of ​​the cut 2070 by activating the winding roller 104. During this process, new sections of the upper tape 3 and lower tape 4 are simultaneously pulled in. Thus, the lower tape 4 is positioned on the right side of the free arm. The holding mechanism, fixing mechanism, and / or clamping mechanism 202 and 203 are closed by means of drivers 204 and 205. Then, the upper tape 3, lower tape 4, and sewn finished tape 6 are relaxed, creating slack that allows the embroidery frame 200 to move in the X and Y directions, respectively. By proceeding to method step b), the next embroidery process for the next tape section begins cyclically.

[0050] The advantages of this invention are: it enables an automated process. Furthermore, the clamping of the upper belt is permanently formed during both stages, resulting in high precision when creating the circumferential connecting seam 5.

[0051] The invention can be extended by an additional conveying mechanism 206 on the lower side of the embroidery frame 200, so that not only can two ribbons be embroidered or sewn together at different stages, but also multiple ribbons can be embroidered or sewn together. Conversely, the invention can convey additional ribbons from a position above the embroidery frame 200, thereby moving additional ribbons onto the upper ribbon 3.
