Description

Technical Field

[0001] This utility model relates to the field of computer embroidery machine technology, and in particular to a feeding mechanism for a sequin mixed embroidery device. Background Technology

[0002] With economic development, people have increasingly higher demands for quality of life, especially in the aesthetics of clothing. Embroidering beads and sequins onto fabrics to create ornaments or patterns is a common practice. Patterns made of beads and sequins have a good three-dimensional decorative effect and have become popular in recent years, especially among women and children.

[0003] In existing technologies, the sequin mixed embroidery device of computer embroidery machines usually adopts an independent loose bead feeding mechanism and an independent sequin feeding mechanism to feed loose beads and sequins respectively. On the one hand, the embroidery patterns are relatively simple and cannot meet customer needs; on the other hand, it increases production costs, reduces production efficiency, and thus reduces economic benefits. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the prior art by providing a feeding mechanism for a sequin mixed embroidery device. This mechanism can feed loose beads of various specifications or colors, as well as sequins of various specifications or colors, and can also feed a mixture of loose beads and sequins. This greatly enriches the embroidery patterns, while reducing production costs, improving production efficiency, and significantly enhancing economic benefits.

[0005] This utility model proposes a feeding mechanism for a sequined mixed embroidery device, comprising multiple hoppers for loading various materials, multiple feeding drive motors for driving the rotation of the multiple hoppers, multiple feeding wires extending from the discharge ports of the multiple hoppers, and multiple material feeding control components; during the rotation of the hoppers, the loaded materials are fed onto the corresponding feeding wires, and the feeding wires feed the fed materials down; the multiple material feeding control components control the timing of the feeding of materials by the multiple feeding wires.

[0006] Furthermore, the material release control component includes a separating clamp assembly and a separating clamp drive assembly. The separating clamp drive assembly drives the separating clamp assembly to open or close. The material threading wire passes through the separating clamp assembly. When the separating clamp assembly is open, it releases the material on the material threading wire. When the separating clamp assembly is closed, it clamps the material threading wire and blocks the material on the material threading wire.

[0007] Furthermore, the separating clamp assembly includes a guide rod arranged in a vertical direction and a plurality of material separating clamps arranged sequentially along the axial direction of the guide rod. The material threading wire passes through the plurality of material separating clamps in sequence, and the separating clamp driving assembly drives the plurality of material separating clamps to open or close sequentially.

[0008] Furthermore, the separating chuck drive assembly includes a rotating rod arranged in a vertical direction and a plurality of chuck drive cams arranged in a spiral shape on the rotating rod. During the rotation of the rotating rod, the plurality of material separating chucks are driven to open or close sequentially by the plurality of chuck drive cams.

[0009] Furthermore, the guide rods are two parallel and spaced apart. The material separating chuck includes an active chuck rotatably connected to one of the guide rods, a driven chuck rotatably connected to the other guide rod, and a chuck control torsion spring sleeved on the two guide rods. One end of the chuck control torsion spring is connected to the chuck control torsion spring, and the other end is connected to the driven chuck. The chuck drive cam drives the active chuck to rotate on the guide rod.

[0010] Furthermore, the active chuck has a toothed groove on the side near the driven chuck, and the driven chuck has gear teeth on the side near the active chuck that mesh with the toothed groove.

[0011] Furthermore, one end of the active chuck is provided with a rocker arm, and a roller is provided at the eccentric position of the chuck drive cam. When the rotating rod rotates at a certain angle, the roller abuts against the rocker arm.

[0012] Furthermore, a drive gear is fixedly mounted on the motor shaft of the material feeding drive motor, a hopper drive gear is fixedly mounted on the bottom of the hopper bin, a chuck drive gear is fixedly mounted on the rotating rod, and the unloading mechanism further includes a driven gear assembly disposed between the drive gear, the hopper drive gear, and the chuck drive gear. The driven gear assembly meshes with the drive gear, the hopper drive gear, and the chuck drive gear, so that when the drive gear rotates, it is transmitted through the driven gear assembly, driving the hopper drive gear and the chuck drive gear to rotate.

[0013] Furthermore, the material lowering control component also includes a separating clamp lifting component, which drives the separating clamp component to move up and down, thereby causing the material-feeding wire to move up and down when the separating clamp component closes and clamps the material-feeding wire.

[0014] Furthermore, the separator chuck lifting assembly includes a lifting ball screw arranged in a vertical direction, a lifting drive motor connected to the lifting ball screw, a screw nut sleeved on the outside of the lifting ball screw, and a lifting seat fixedly connected to the screw nut, the lifting seat being fixedly connected to the separator chuck assembly.

[0015] The feeding mechanism of the sequin mixed embroidery device proposed in this utility model has the following beneficial effects:

[0016] (1) The multiple hoppers of this feeding mechanism can be loaded with materials of various colors or specifications respectively. The wire can be used to lower the materials in the hoppers. The material lowering control component can control the timing of material lowering. This allows the feeding mechanism to achieve the feeding of loose beads of various specifications or colors, the feeding of gold flakes of various specifications or colors, and the feeding of mixed loose beads and gold flakes. This greatly enriches the embroidery patterns, reduces production costs, improves production efficiency, and greatly enhances economic benefits.

[0017] (2) The material feeding control component of this feeding mechanism includes a separating clamp assembly and a separating clamp drive assembly. The feeding wire passes through the separating clamp assembly. The separating clamp drive assembly is used to drive the separating clamp assembly to open or close, thereby releasing or blocking the material on the feeding wire through the separating clamp assembly, and controlling the feeding sequence of the material on the feeding wire.

[0018] (3) The separating clamp assembly of this feeding mechanism includes a guide rod and multiple material separating clamps. The guide rod is set in the vertical direction, and the multiple material separating clamps are distributed in sequence along the axial direction on the guide rod. The material threading wire passes through the multiple material separating clamps in sequence. The separating clamp driving assembly drives the multiple material separating clamps to open or close in sequence from top to bottom, so that the multiple material separating clamps release or block the material on the material threading wire in sequence, thereby realizing the control of the material release sequence on the material threading wire.

[0019] (4) The separating chuck drive assembly of this feeding mechanism includes a rotating rod and multiple chuck drive cams. The rotating rod is set in the vertical direction, and the multiple chuck drive cams are spirally distributed on the rotating rod and correspond one-to-one with multiple material separating chucks. During the rotation of the rotating rod, the multiple chuck drive cams drive the multiple material separating chucks to open or close sequentially from top to bottom, so that the multiple material separating chucks release or block the material on the wire in sequence, thereby realizing the control of the material release sequence on the wire.

[0020] (5) The active chuck of this feeding mechanism has a toothed groove on the side near the driven chuck, and the driven chuck has a gear tooth on the side near the active chuck. When the chuck driving cam drives the active chuck to rotate on the guide rod, the interaction between the gear tooth and the toothed groove drives the driven chuck to rotate in the opposite direction on the guide rod, thereby increasing the distance between the active chuck and the driven chuck, so that the material threaded on the feeding wire can pass better between the active chuck and the driven chuck.

[0021] (6) The active chuck of this feeding mechanism is provided with a rocker arm at the other end away from the guide rod, and a roller is provided at the eccentric position of the chuck drive cam. During the rotation of the chuck drive cam, the active chuck is driven to rotate on the guide rod through the roller and the rocker arm, so that the material separation chuck opens. After the roller rolls over the rocker arm, the material separation chuck is closed through the elastic force of the torsion spring controlled by the chuck, so as to realize the release or blocking of the material on the wire by the material separation chuck.

[0022] (7) By setting a driven gear assembly, the material feeding mechanism drives the material feeding drive motor to drive the hopper to rotate while driving the rotating rod to rotate. This reduces the number of motors and lowers the cost of the material feeding mechanism. It also makes the structure of the material feeding mechanism more compact and reduces the space occupied by the material feeding mechanism. This makes it easier to install the material feeding mechanism on the sequin mixed embroidery device.

[0023] (8) The material feeding control component of this feeding mechanism also includes a separating clamp lifting component. The separating clamp lifting component drives the separating clamp component to lift and lower, so that the separating clamp component drives the threading wire to lift and lower synchronously, thereby changing the distance from the bottom of the threading wire to the downstream feeding device, further enabling this feeding mechanism to adapt to a large number of gold sequin stacking feeding, and thus enabling the sequin mixed embroidery device to adapt to a large number of gold sequin stacking embroidery.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0033] Please see Figures 1-6 The feeding mechanism of a sequin mixed embroidery device according to an embodiment of the present invention includes multiple hoppers 1 that are respectively loaded with various materials, multiple feeding drive motors 2 that drive the multiple hoppers 1 to rotate, multiple feeding wires 3 that extend from the discharge ports of the multiple hoppers 1, and multiple material feeding control components. During the rotation of the hoppers 1, the loaded materials are fed onto the corresponding feeding wires 3, and the feeding wires 3 feed the fed materials. The multiple material feeding control components control the timing of the feeding of materials by the multiple feeding wires 3.

[0034] In this application, the feeding mechanism includes multiple hoppers 1, multiple feeding drive motors 2, multiple feeding wires 3, and multiple material feeding control components. The multiple hoppers 1, multiple feeding drive motors 2, multiple feeding wires 3, and multiple material feeding control components are all mounted on the frame of the computer embroidery machine.

[0035] Each hopper 1 is loaded with material of one color or specification, thus multiple hoppers 1 can be used to load materials of multiple colors or specifications. Specifically, in this application, the material can be loose beaded material or gold flake material, meaning that multiple hoppers 1 can load loose beaded material of multiple colors or specifications, or gold flake material of multiple colors or specifications. Each feed drive motor 2 drives one hopper 1 to rotate, thus multiple feed drive motors 2 can drive multiple hoppers 1 to rotate respectively.

[0036] Each threading wire 3 extends from the discharge port of a hopper 1. When multiple threading drive motors 2 drive multiple hoppers 1 to rotate, causing the material in each hopper 1 to rotate, the material loaded in each hopper 1 is threaded onto the corresponding threading wire 3. After extending from the discharge port of the hopper 1, the threading wire 3 extends downwards, allowing the material threaded onto the threading wire 3 to be lowered along the threading wire 3 under its own weight.

[0037] Each material release control component controls the material release timing on a material threading wire 3, thereby controlling the material release timing on the corresponding material threading wire 3 through multiple material release control components.

[0038] Therefore, in this application, when multiple hoppers 1 are respectively loaded with loose beaded auxiliary materials of various colors or specifications, the feeding mechanism can simultaneously feed loose beaded auxiliary materials of various colors and specifications; when multiple hoppers 1 are respectively loaded with gold flake auxiliary materials of various colors or specifications, the feeding mechanism can simultaneously feed gold flake auxiliary materials of various colors and specifications.

[0039] When one part of the hopper 1 is loaded with loose beads and the other part of the hopper 1 is loaded with gold flakes, it is possible to achieve mixed feeding of loose beads and gold flakes, which greatly enriches the embroidery patterns, reduces production costs, improves production efficiency, and greatly enhances economic benefits.

[0040] Specifically, in this application, the specific structure of the hopper 1 can be referred to the Chinese utility model patent with publication number CN218263073U and patent name "A feeding cup mechanism for intermittent feeding". Although the feeding cup mechanism is used for feeding loose beads, the principle of gold sheet feeding in this application is the same as that of loose bead feeding, except that the loose beads loaded in the feeding cup are changed to gold sheets.

[0041] Specifically, in this embodiment, the material release control component includes a separator clamp assembly 4 and a separator clamp drive assembly 5, wherein the separator clamp drive assembly 5 is used to drive the separator clamp assembly 4 to open or close. The threading wire 3 passes through the separator clamp assembly 4. When the separator clamp drive assembly 5 drives the separator clamp assembly 4 to open, the material threaded on the threading wire 3 can pass through the separator clamp assembly 4, thereby allowing the separator clamp assembly 4 to release the material on the threading wire 3.

[0042] When the separating clamp drive assembly 5 drives the separating clamp assembly 4 to close, the separating clamp assembly 4 clamps the material threading wire 3 and blocks the material threaded on the material threading wire 3, thereby controlling the timing of material release on the material threading wire 3, so that the feeding mechanism can simultaneously feed materials of multiple colors and specifications.

[0043] Specifically, in this embodiment, the separating clamp assembly 4 includes a guide rod 41 and multiple material separating clamps 42. The guide rod 41 is arranged vertically, and the multiple material separating clamps 42 are distributed axially along the guide rod 41. The threading steel wire 3 passes through the multiple material separating clamps 42 in sequence. When the threading steel wire 3 lowers the threaded material, the separating clamp driving assembly 5 drives the multiple material separating clamps 42 to open or close sequentially from top to bottom, so that the multiple material separating clamps 42 sequentially release or block the material on the threading steel wire 3, thereby controlling the timing of the material release on the threading steel wire 3.

[0044] In this application, the material feeding mechanism feeds the material by threading it through the threading wire 3 and guiding it to the subsequent embroidery device. Therefore, it is foreseeable that when the separating clamp drive assembly 5 drives multiple material separating clamps 42 to open or close sequentially from top to bottom, at least one material separating clamp 42 will be in a closed state. This will clamp the threading wire 3 through at least one closed material separating clamp 42, preventing the threading wire 3 from swinging and thus ensuring the accuracy of the material feeding mechanism.

[0045] Specifically, in this embodiment, the separating chuck drive assembly 5 includes a rotating rod 51 and a plurality of chuck drive cams 52, wherein the rotating rod 51 is arranged in a vertical direction, and the plurality of chuck drive cams 52 are spirally distributed on the rotating rod 51 and correspond one-to-one with the plurality of material separating chucks 42.

[0046] During the rotation of the rotating rod 51, multiple chuck drive cams 52 are driven to rotate synchronously. This causes multiple material separating chucks 42 to open or close sequentially from top to bottom, allowing the multiple material separating chucks 42 to release or block the material on the threading wire 3 in sequence, thereby controlling the timing of material release on the threading wire 3.

[0047] In this embodiment, there are two guide rods 41 arranged in parallel and spaced apart. The material separating clamp 42 includes an active clamp 421, a driven clamp 422, and a clamp control torsion spring 423. The active clamp 421 is rotatably connected to one of the guide rods 41, and the driven clamp 422 is rotatably connected to the other guide rod 41, so that the active clamp 421 and the driven clamp 422 are arranged in parallel and spaced apart. The clamp control torsion spring 423 is sleeved on both guide rods 41, with one end fixedly connected to the active clamp 421 and the other end fixedly connected to the driven clamp 422.

[0048] The wire 3 passes between the active chuck 421 and the driven chuck 422. The active chuck 421 is driven to rotate on the guide rod 41 by the chuck drive cam 52, so that the active chuck 421 and the driven chuck 422 move away from each other, releasing the wire 3 and allowing the material on the wire 3 to pass between the active chuck 421 and the driven chuck 422, thereby releasing the material on the wire 3.

[0049] When the chuck drive cam 52 no longer drives the active chuck 421, under the elastic force of the chuck control torsion spring 423, the active chuck 421 and the driven chuck 422 move closer to each other to clamp the threading wire 3 and block the material threaded on the threading wire 3. This allows the timing of material release on the threading wire 3 to be controlled, enabling the feeding mechanism to feed multiple colors and specifications of materials simultaneously.

[0050] Furthermore, in this embodiment, the active chuck 421 has a toothed groove 4211 on the side near the driven chuck 422, and the driven chuck 422 has a gear tooth 4221 on the side near the active chuck 421. The gear tooth 4221 meshes with the toothed groove 4211, so that when the chuck drive cam 52 drives the active chuck 421 to rotate on the guide rod 41, the interaction between the gear tooth 4221 and the toothed groove 4211 drives the driven chuck 422 to rotate in the opposite direction on the guide rod 41, thereby causing the active chuck 421 and the driven chuck 422 to move away from each other and increasing the distance between the active chuck 421 and the driven chuck 422, so that the material threaded on the threading wire 3 can pass better between the active chuck 421 and the driven chuck 422.

[0051] Furthermore, in this embodiment, a rocker arm 4212 is provided at the other end of the active chuck 421 away from the guide rod 41, and a roller 521 is provided at the eccentric position of the chuck drive cam 52. When the rotating rod 51 rotates at a certain angle, it drives the chuck drive cam 52 and the roller 521 to rotate synchronously at a certain angle, so that the roller 521 abuts against the rocker arm 4212 on the active chuck 421. Thus, when the rotating rod 51 continues to rotate, driving the chuck drive cam 52 and the roller 521 to continue to rotate, the roller 521 applies a force to the rocker arm 4212, driving the active chuck 421 to rotate on the guide rod 41.

[0052] At this time, under the interaction of the gear teeth 4221 and the tooth groove 4211, the driven chuck 422 rotates in the opposite direction on the guide rod 41, thereby causing the active chuck 421 and the driven chuck 422 to move away from each other, releasing the material threading wire 3, and allowing the material threaded on the material threading wire 3 to pass between the active chuck 421 and the driven chuck 422, thereby releasing the material on the material threading wire 3.

[0053] As the rotating rod 51 continues to rotate, it abuts against the swing rod 4212 via the roller 521, driving the active chuck 421 and the swing rod 4212 to rotate synchronously at a certain angle. Then, the roller 521 rolls over the swing rod 4212. At this time, the roller 521 no longer applies force to the swing rod 4212. Under the elastic force of the chuck control torsion spring 423, the active chuck 421 and the driven chuck 422 move closer to each other to clamp the threading wire 3 and simultaneously block the material threaded on the threading wire 3. This allows control over the timing of material release on the threading wire 3, enabling the feeding mechanism to simultaneously feed materials of multiple colors and specifications.

[0054] In this embodiment, a drive gear 21 is fixedly installed on the motor shaft of the material feeding drive motor 2, a hopper drive gear 11 is fixedly installed at the bottom of the hopper bin 1, a chuck drive gear 511 is fixedly installed on the rotating rod 51, and the feeding mechanism also includes multiple sets of driven gear assemblies 6. Each set of driven gear assemblies 6 is arranged between a drive gear 21, a hopper drive gear 11, and a chuck drive gear 511.

[0055] The driven gear assembly 6 meshes simultaneously with the driving gear 21, the hopper drive gear 11, and the chuck drive gear 511. Thus, when the motor shaft of the material drive motor 2 rotates, driving the driving gear 21 to rotate synchronously, the driven gear assembly 6 transmits power, driving the hopper drive gear 11 and the chuck drive gear 511 to rotate synchronously, thereby driving the hopper 1 to rotate and the rotating rod 51 to rotate.

[0056] It is foreseeable that in this application, the driven gear assembly 6 is composed of multiple driven gears. Therefore, when the driving gear 21 rotates, it drives the hopper drive gear 11 and the chuck drive gear 511 to rotate synchronously through the driven gear assembly 6. The direction of rotation between the hopper drive gear 11 and the chuck drive gear 511 and the driving gear 21 may be the same or opposite. Specifically, in actual implementation, the number and gear ratio of the driven gears in the driven gear assembly 6 can be designed according to actual needs.

[0057] In this application, by setting the driven gear assembly 6, the feeding drive motor 2 drives the hopper 1 to rotate while driving the rotating rod 51 to rotate. Thus, the rotation of the rotating rod 51 drives the separating clamp assembly 4 to open or close. That is, the rotation of the hopper 1 for feeding and the opening or closing of the separating clamp assembly 4 are both driven by the feeding drive motor 2.

[0058] On the one hand, it reduces the number of motors used in this feeding mechanism, thereby reducing the cost of this feeding mechanism; on the other hand, it makes the structure of this feeding mechanism more compact, reducing the space occupied by this feeding mechanism, thus making it easier to install and set up this feeding mechanism on a multi-material sequin mixed embroidery device.

[0059] Furthermore, in this embodiment, the material lowering control component also includes a separator clamp lifting component 7, which is used to drive the separator clamp component 4 to move up and down. As mentioned in the previous embodiment, when the separator clamp driving component 5 drives multiple material separator clamps 42 to open or close sequentially from top to bottom, at least one material separator clamp 42 is in a closed state.

[0060] In this application, when at least one material separator 42 is in a closed state and clamps the threading wire 3, the separator chuck lifting assembly 7 drives the separator chuck assembly 4 to rise and fall, so that the separator chuck assembly 4 drives the threading wire 3 to rise and fall synchronously, thereby changing the distance from the bottom of the threading wire 3 to the downstream feeding device.

[0061] In practical applications, in order to ensure that the downstream feeding device can smoothly deliver the material after the material is delivered by the feeding mechanism, the bottom height of the threading wire 3 needs to be raised above the material so that the material is no longer threaded on the threading wire 3. This avoids the material still being threaded on the threading wire 3 when the downstream feeding device delivers the material, which would otherwise obstruct the delivery of the material.

[0062] Therefore, in this application, after the wire threading steel wire 3 delivers the material to the downstream feeding device, the separating clamp assembly 4 is driven to rise by the separating clamp lifting assembly 7, so that the separating clamp assembly 4 drives the wire threading steel wire 3 to rise synchronously, thereby raising the bottom height of the wire threading steel wire 3 above the material.

[0063] Because the material is relatively light, the distance between the bottom of the threading wire 3 and the downstream feeding device cannot be too large during feeding to prevent the material from failing to accurately fall into the downstream feeding device after falling from the bottom of the threading wire 3. Therefore, in this application, after one feeding is completed, the separating clamp assembly 4 is driven to descend by the separating clamp lifting assembly 7, so that the separating clamp assembly 4 drives the threading wire 3 to descend synchronously, thereby keeping the distance between the bottom of the threading wire 3 and the downstream feeding device within a suitable range, waiting for the next feeding, so that the threading wire 3 can accurately deliver the material to the downstream feeding device.

[0064] During the actual feeding process, the height of the threading wire 3 after it descends remains fixed. Specifically, the distance between the bottom of the threading wire 3 and the downstream feeding device after it descends does not exceed the thickness of one material, thereby ensuring that the threading wire 3 accurately feeds the material into the downstream feeding device.

[0065] When the feeding mechanism feeds the gold foil auxiliary material, the thickness of the stacked gold foil auxiliary material changes as the number of gold foil auxiliary materials stacked during the feeding process varies. Therefore, in this application, after the threading wire 3 feeds multiple stacked gold foil auxiliary materials to the downstream feeding device, the lifting assembly 7 of the separating clamp can change the lifting height of the bottom of the threading wire 3 according to the stacking thickness of different numbers of gold foil auxiliary materials. This ensures that after different numbers of gold foil auxiliary materials are fed into the downstream feeding device, they will no longer be threaded onto the threading wire 3, thereby enabling the feeding mechanism to feed different numbers of stacked gold foil auxiliary materials, and thus adapting the sequin mixed embroidery device to different numbers of stacked embroidery.

[0066] Specifically, in this embodiment, the separator chuck lifting assembly 7 includes a lifting ball screw 71, a lifting drive motor 72, a screw nut 73, and a lifting seat 74. The lifting ball screw 71 is arranged in a vertical direction, and the lifting drive motor 72 is connected to the lifting ball screw 71. Thus, the lifting ball screw 71 is driven to rotate in both directions synchronously by the forward and reverse rotation of the lifting drive motor 72.

[0067] The lead screw nut 73 is sleeved on the lifting ball screw 71. The threaded pair of the lead screw nut 73 is screwed into the external thread of the lifting ball screw 71, so that the lifting ball screw 71 drives the lead screw nut 73 to move up and down in the vertical direction during the forward and reverse rotation.

[0068] One end of the lifting seat 74 is fixedly connected to the screw nut 73, and the other end is fixedly connected to the lifting clamp assembly. Thus, when the separating clamp assembly 4 clamps the threaded steel wire 3, the screw nut 73 moves up and down in the vertical direction, thereby driving the separating clamp assembly 4 and the threaded steel wire 3 to move up and down in the vertical direction simultaneously, thereby changing the distance from the bottom of the threaded steel wire 3 to the downstream feeding device.

[0069] Specifically, when the active chuck 421 and the driven chuck 422 are rotatably connected to the two guide rods 41 in the horizontal direction, they remain relatively fixed to the two guide rods 41 in the vertical direction. Therefore, in this application, one end of the lifting seat 74 is fixedly connected to the lead screw nut 73, and the other end is fixedly connected to the two guide rods 41.

[0070] When the lead screw nut 73 moves up and down in the vertical direction, the lifting seat 74 drives the two guide rods 41, as well as the active chuck 421 and the driven chuck 422 on them, to rotate synchronously in the vertical direction. Thus, when the active chuck 421 and the driven chuck 422 clamp the wire 3, they drive the wire 3 to move up and down synchronously in the vertical direction, changing the distance from the bottom of the wire 3 to the downstream feeding device.

[0071] The above-described contents can be implemented individually or in combination in various ways, and all such variations are within the protection scope of this utility model.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
