Description

Braiding carrier replacement device

[0001] The present invention relates to a braiding carrier replacement device that enables the rapid replacement of a used carrier in order to minimize the downtime of a braider and improve productivity.

[0002]

[0003] Generally, a braider (braid machine) arranges a number of carriers (or a device that includes a yarn carrier, a yarn feeder, and a bobbin wound with yarn, and controls the appropriate tension when the yarn is unwound), and the carriers are guided in a regular direction to braid a diagonal braid (or braided sleeve) with a surface having a constant angle through the mutual twisting of the yarn wound on each bobbin.

[0004] In other words, a braider is a device that twists multiple threads to create a cord or tube of a desired shape. It operates by having bobbins (carriers) wound with threads move in a specific pattern to twist and weave the threads. By controlling the tension of the threads unwound from these bobbins, a uniform product can be produced, and the product made in this way is called a braid.

[0005] First, a biaxial braider is a braider in which threads are intersected diagonally to form a braid, and a three-dimensional braider manufactures a braid in which multiple threads are braided into a three-dimensionally integrated structure (multiple layers) by arranging multiple carriers into a square matrix structure having multiple matrices or by arranging multiple carriers in a circular manner.

[0006] In such braiders, carriers are generally arranged mainly in a planar configuration. As an example of a braider in which carriers are arranged in a planar configuration, Korean Patent Registration No. 10-1571488 describes a three-dimensional circular braiding machine with a structure that arranges circularly arranged horn gears in multiple layers.

[0007] However, conventional braiding machines must stop operation and replace the bobbin with a new one wound with yarn when the yarn on the carrier is exhausted. At this time, the process of removing used bobbins one by one from the track board and replacing them with new ones is time-consuming, leading to reduced productivity and causing fatigue among workers. In particular, this problem is more severe in large braiding machines, which can result in decreased productivity and an increased risk of injury to workers.

[0010]

[0011] The present invention is designed to solve the aforementioned problems and relates to a braiding carrier replacement device that increases work efficiency by allowing the carriers arranged in the braider to be easily replaced using a replacement cassette.

[0012]

[0013] A braiding carrier replacement device according to the present invention for implementing the purpose described above comprises: a carrier that supplies yarn necessary for braiding while supporting and rotating a bobbin wound with yarn; a track plate on which a circular track is formed for the movement of the carrier; and a plurality of braiding horn gears installed on the track plate, wherein the outer surfaces interlock and rotate with each other and the carrier is supported by a groove formed on the outer surface and moves along the circular track, and is configured to replace a carrier from a braider that twists yarn to knit a braid. The device further comprises: a replacement cassette configured to be positioned adjacent to the track plate of the braider and including a cassette track on which the carrier can move, which stores a used carrier discharged from the braider and extracts a new carrier stored in advance inside and feeds it into the braider; and a branching track that branches the carrier to move from the circular track of the track plate to the cassette track of the replacement cassette. It may be configured to include a branching horn gear in which the outer surface rotates in engagement with the outer surface of the braiding horn gear of the braider, and the carrier is supported by a groove formed on the outer surface to move along the branching track.

[0014] Additionally, the branch track may be composed of a discharge branch track that moves a used carrier to the replacement cassette and an input branch track that receives a new carrier from the replacement cassette and moves it to the braider.

[0015] Additionally, the branching track is composed of a circulation groove and a branching groove that switch the movement path of the carrier between the circulation track of the track plate and the cassette track of the replacement cassette, and can be configured to selectively guide the movement path of the carrier by changing the positions of the circulation groove and the branching groove.

[0016] Additionally, the branch track may further comprise a branch driving module that switches the positions of the circulation groove and the branch groove of the branch track to switch between a bracing mode for performing bracing and a carrier replacement mode for replacing the carrier; and a branch control module that controls the operation of the branch driving module.

[0017] In addition, it may further include a sensor installed on the carrier to detect the remaining amount of yarn wound on the bobbin.

[0018] In addition, the above branching gear may be composed of a discharge gear that moves the carrier to a replacement cassette after use, and an input gear that receives a new carrier from the replacement cassette and moves it to a braider.

[0019] Additionally, the circulation track of the above track plate may include a first circulation track configured to rotate the carrier in one direction and a second circulation track configured to rotate in the opposite direction to the first circulation track.

[0020] Additionally, the replacement cassette may include a first cassette for storing a used carrier that moves along a first circulation track of the track plate, and a second cassette for storing a used carrier that moves along a second circulation track of the track plate.

[0021] In addition, the above replacement cassette may be formed in multiple numbers so as to replace multiple carriers simultaneously.

[0022] In addition, the cassette track of the above-mentioned replacement cassette may include grooves that extend continuously in a zigzag arrangement.

[0023] Additionally, the above replacement cassette may include a plurality of cassette horn gears installed on the cassette track, wherein the outer surfaces interlock and rotate with each other, and the carrier is supported by a groove formed on the outer surface and configured to move along the groove.

[0024] In addition, the cassette horn gear of the replacement cassette may be additionally arranged in a predetermined number compared to the braiding horn gear of the braider, so that when the carrier of the braider is discharged, the carrier located on the discharge branch track is sequentially fed into the replacement cassette, and when the carriers located between the discharge branch track and the input branch track pass through the input branch track point, the carriers located in the replacement cassette are sequentially fed into the braider.

[0025] In addition, the cassette horn gear of the replacement cassette, which is added in addition to the braiding horn gear of the braider, may be configured to be empty without accommodating the new carrier.

[0026] In addition, the cassette horn gear of the replacement cassette, which is added in addition to the braiding horn gear of the braider, may be configured to be sequentially arranged in a position facing the discharge branch track.

[0027] In addition, the replacement cassette may include a plurality of sprockets installed on the cassette track and a chain connected to the sprockets and circulating, and the chain may be configured such that a plurality of support members supporting the carrier are installed at regular intervals so that the carrier is moved by the chain.

[0028] Additionally, the replacement cassette further includes a guide rail installed along the direction in which the chain extends to guide the movement path of the carrier; the guide rail may be configured to maintain a certain distance from the chain link.

[0029] Additionally, a method for replacing a braiding carrier using a braiding carrier replacement device may include: a step of stopping braiding when the remaining amount of yarn wound on the bobbin of the carrier is determined to be below a predetermined reference value; a step of cutting the yarn wound on the bobbin of the carrier and temporarily fixing it using a clamp; a step of operating the branch track to discharge the used carrier from the braider into a replacement cassette for storage, and simultaneously receiving the carrier before use from the replacement cassette and moving it to the braider for replacement; a step of returning the branch track to its original position so that the carrier moves along the existing track; a step of separating the yarn temporarily fixed by the clamp from the clamp and connecting it to the yarn of the carrier before use that has been fed into the braider; and a step of resuming braiding using the connected yarn.

[0030] Additionally, it may include a carrier that supplies yarn necessary for braiding while supporting and rotating a bobbin wound with yarn; a track plate on which a circular track is formed for the carrier to move; a plurality of braiding gears installed on the track plate, wherein the outer surfaces interlock and rotate with each other, and the carrier is supported by a groove formed on the outer surface and configured to move along the circular track; and a braiding carrier replacement device according to any one of claims 1 to 14.

[0031]

[0032] The braiding carrier replacement device according to the present invention, configured as described above, can shorten the operating time of a braiding machine because it allows multiple carriers to be discharged at once for easy replacement. Accordingly, it can improve work productivity and reduce worker fatigue by reducing repetitive bobbin replacement tasks.

[0069] Furthermore, throughout the specification, when a part is described as "including" a certain component, this means that, unless specifically stated otherwise, it does not exclude other components but may include additional components.

[0070] FIG. 1 is a drawing illustrating the overall appearance of a braiding machine including a braiding carrier replacement device according to the present invention.

[0071] As shown in FIG. 1, a braiding carrier replacement device (A) according to a preferred embodiment of the present invention may be configured to be arranged adjacent to a braider (100) and largely composed of a replacement cassette (200), a branch track (300), and a branch horn gear (400).

[0072]

[0073] The configuration of the present invention is described in detail as follows.

[0074]

[0075] First, before describing the braiding carrier replacement device (A), we will describe the braider (100) that forms the braid.

[0076] A braider (100) is an essential piece of equipment for producing various textile products, and it plays the role of twisting threads to create strong and beautiful cords or fabrics. Although the braider (100) has a complex structure, it can be broadly divided into three main components: a carrier (110), a track plate (120), and a braiding horn gear (130).

[0077] Referring to FIG. 2, the carrier (110) has a structure in which a bobbin (111) and gliding shoes are connected as one unit, and the gliding shoes (112) are composed of an upper plate and a lower plate, with the bobbin (111) connected to the upper plate and a pin connected to the lower plate that fits into the groove of the braiding horn gear (130), thereby enabling stable movement. The bobbin (111) has a built-in thread tension adjustment device (not shown) so that the thread can always be unwound with a constant force.

[0078] In other words, the carrier (110) is fitted into the groove of the track plate (120) to support the gliding shoe and the bobbin (111) on which the yarn is wound, and as the bobbin (111) rotates, the carrier (110) also rotates together and serves to supply the yarn necessary for knitting the braid.

[0079] At this time, multiple carriers (110) can operate simultaneously to create complex patterns by combining threads of various colors and thicknesses. Meanwhile, the carrier (110) may further include a sensor (not shown), such as a transmissive light sensor, a reflective light sensor, or a pressure sensor, to detect the remaining amount of thread wound on the bobbin (111).

[0080] Referring to FIG. 3, the track plate (120) is in the form of a plate that forms a circular track by having a groove through which the carrier (110) moves, and the type and specifications of the braid can be determined according to the shape and size of the track plate (120). The track plate (120) is generally manufactured in an elliptical or circular shape, and the circular track of the track plate (120) may include a first circular track (120a) configured to rotate the carrier (110) in one direction and a second circular track (120b) configured to rotate in the opposite direction to the first circular track (120a). Here, the first circular track (120a) and the second circular track (120b) may represent clockwise and counterclockwise movements, respectively.

[0081] Referring to FIG. 4, a plurality of braiding horn gears (130) are installed on a track plate (120) to support a carrier (110) and move along a circular track. On the outer surface of the braiding horn gear (130), interlocking grooves are formed in all directions, and the carrier (110) is caught in these grooves and moves along the circular track of the track plate (120). At this time, the density and degree of twisting of the braid can be controlled by adjusting the rotational speed and direction of the braiding horn gear (130).

[0082]

[0083] Next, the replacement cassette (200), branch track (300), and branch horn gear (400) of the braiding carrier replacement device (A) will be described.

[0084] Referring to FIG. 5, the replacement cassette (200) is configured to be positioned on the outer surface of the track plate (120) of the braider (100). This replacement cassette (200) may have a predetermined path, for example, a continuous groove in the form of a zigzag, forming a cassette track (210), and the carrier (110) may be grasped through a cassette horn gear (211) or a support member (214) installed on the cassette track (210) and move along the cassette track (210).

[0085] The above cassette track (210) can store a used carrier (110) discharged from the braider (100) inside, and can also extract a pre-used carrier (110) stored inside and feed it into the braider (100). Specifically, the replacement cassette (200) may include a first cassette (210a) that stores a used carrier (110) moving along a first circulation track (120a) of the track plate (120), and a second cassette (210b) that stores a used carrier (110) moving along a second circulation track (120b) of the track plate (120).

[0086] In addition, the replacement cassette (200) may be composed of multiple units to replace a large number of carriers (110) simultaneously. For example, if there are 128 braiding horn gears (130) on the track plate (120) of the braider (100), two replacement cassettes (200) may be used to accommodate carriers (110) moving along the first circulation track (120a) and the second circulation track (120b), respectively. In this case, 64 cassette horn gears (211) may be installed in each replacement cassette (200). Additionally, if the number of replacement cassettes (200) is increased to four, 32 cassette horn gears (211) may be installed in each replacement cassette (200) to efficiently distribute and accommodate the carriers (110).

[0087] Meanwhile, a cassette horn gear (211) for moving the carrier (110) can be installed in the replacement cassette (200).

[0088] Referring to FIG. 6, a plurality of cassette horn gears (211) may be installed on the cassette track (210). These cassette horn gears (211) may be configured such that their outer surfaces interlock and rotate, and the carrier (110) is supported by grooves formed in all directions on the outer surfaces and moves along the grooves.

[0089] Referring to FIG. 7, the replacement cassette (200) according to another embodiment may include a plurality of sprockets (212) installed on the cassette track (210) and a chain (213) connected to the sprockets (212) and circulating. A plurality of support members (214) supporting the carrier (110) may be installed on the chain (213) at regular intervals so that the carrier (110) can move by the chain (213). At this time, there is a risk that the support members (214) supporting the lower end of the carrier (110) may lose the carrier (110) during movement. To solve this problem, a guide rail (215) may be installed in the replacement cassette (200) parallel to the direction in which the chain (213) moves. The guide rail (215) guides the path so that the carrier (110) can move stably and maintains a constant distance from the chain (213) to prevent the carrier (110) from coming off the support member (214).

[0090] Referring to FIG. 8, the cassette horn gear (211) of the replacement cassette (200) may be arranged in a number of additional units compared to the braiding horn gear (130) of the braider (100). At this time, when switching from braiding mode to carrier replacement mode, the carrier (110) of the braider (100) is sequentially fed into the replacement cassette (200) starting from the carrier (110) located on the discharge branch track (300a), and when the carriers (110) located in the space (S) between the discharge branch track (300a) and the input branch track (300b) pass through the input branch track (300b), the carrier (110) located on the replacement cassette (200) may be sequentially fed into the braider (100).

[0091] Additionally, the cassette horn gear (211), which is added in addition to the braiding horn gear (130), is left empty without accommodating the carrier (110), thereby smoothly accommodating the carrier (110) sequentially fed from the discharge branch track (300a) and securing a waiting space between the input branch track (300b) and the replacement cassette (200) to prevent interference between the carriers (110). In this case, it is preferable that the cassette horn gear (211), which is added in addition to the braiding horn gear (130), be sequentially positioned in a location facing the discharge branch track (300a).

[0092] As shown in FIG. 9, for example, when operating the carrier replacement mode, if there are three carriers (110) in the space (S) between the discharge branch track (300a) and the input branch track (300b), three additional cassette horn gears (211) can also be installed in addition to the braiding horn gear (130). At this time, as all three carriers (110) located in the space (S) between the discharge branch track (300a) and the input branch track exit the input branch track (300b) point, new carriers (110) are also filled into the three additional cassette horn gears (211) in the replacement cassette (200). That is, when the used carrier (110) is completely moved to the replacement cassette (200), all new carriers (110) are fed into the braider (100) and can be replaced efficiently.

[0093] In addition, just like the cassette horn gear (211), the aforementioned sprocket (212), chain (213), and support (214) system may also have a support (214) additionally installed to perform the same function.

[0094] Referring to FIGS. 10 and 11, the branch track (300) serves to change the path so that the carrier (110) moves from the first circulation track (120a) and the second circulation track (120b) of the track plate (120) to the replacement cassette (200). Specifically, the branch track (300) may be composed of an discharge branch track (300a) that moves the carrier (110) after use to the replacement cassette (200) and an input branch track (300b) that receives the carrier (110) before use from the replacement cassette (200) and moves it to the braider (100).

[0095] It is composed of a circulation groove (310a) and a branching groove (310b) that switch the movement path of the carrier (110) between the circulation track of the track plate (120) and the cassette track (210) of the replacement cassette (200), and the movement path of the carrier (110) can be selectively guided by changing the position of the circulation groove (310a) and the branching groove (310b).

[0096] In addition, the branch track (300) may further include a branch driving module (320) that switches the positions of the circulation groove (310a) and the branching groove (310b) of the branch track (300) to switch between a brading mode that performs brading and a carrier replacement mode that replaces the carrier (110), and a branch control module (330) that controls the operation of the branch driving module (320).

[0097] Meanwhile, the branch drive module (320) can be controlled by the branch control module (330) and the sensor signal of the aforementioned carrier (110). That is, when the thread of the bobbin (111) is almost used up, the sensor detects this and can provide a notification to the user to change from braiding mode to carrier replacement mode.

[0098] Referring again to FIG. 11, the branching horn gear (400) may be configured such that its outer surface is interposed between the outer surface of the braiding horn gear (130) of the braider (100) and the outer surface of the cassette horn gear (211) of the replacement cassette (200), so that they mesh and rotate with each other, and the carrier (110) is supported by grooves formed in all directions on the outer surface and moves along the branching track (300). This branching horn gear (400) may be composed of a discharge horn gear (400a) that moves the carrier (110) after use to the replacement cassette (200), and an input horn gear (400b) that receives the carrier (110) before use from the replacement cassette (200) and moves it to the braider (100). Accordingly, when the position of the branch track (300) described above is changed, the carrier (110) that previously circulated through the braider (100) moves to the replacement cassette (200) via the discharge mixing gear (400a) along the branching groove (310b) of the branch track (300), and at the same time, the carrier (110) that was stored in the replacement cassette (200) moves to the braider (100) via the input mixing gear (400b) through the branching groove (310b) of the branch track (300), and thus the carrier (110) is replaced and the system can be switched to a carrier replacement mode.

[0099]

[0100] Below, a method for replacing a braiding carrier using the braiding carrier replacement device described above is explained.

[0101] Referring to FIG. 12, a method for replacing a braiding carrier according to an embodiment of the present invention may be described as follows: a step of stopping braiding when the remaining amount of yarn wound on the bobbin of the carrier is determined to be less than or equal to a predetermined reference value (S10); a step of cutting the yarn wound on the bobbin of the carrier and temporarily fixing it using a clamp (S20); a step of operating the branch track to discharge the used carrier from the braider into a replacement cassette and storing it, and at the same time receiving a new carrier from the replacement cassette and moving it to the braider to replace it (S30); a step of returning the branch track to its original position so that the carrier moves along the existing track (S40); a step of separating the yarn temporarily fixed with the clamp from the clamp and connecting it to the yarn of the new carrier introduced into the braider (S50); and a step of resuming braiding using the connected yarn (S60).

[0102] Specifically, in the step (S10) of stopping the braiding, the user visually checks the remaining amount of yarn wound on the bobbin (111), or a sensor installed on the carrier (110) detects the remaining amount of yarn and notifies the user. That is, if the sensor determines that the remaining yarn is less than a preset threshold, it sends a notification to the user to stop the braiding.

[0103] Next, in the step (S20) of temporarily fixing using a clamp (not shown), when the braiding mode is interrupted, the user cuts the thread wound on the bobbin (111) to an appropriate length and then uses a clamp to safely and temporarily fix the end of the thread.

[0104] Next, in the replacement step (S30), when the branch track (300) is operated, the used carrier (110) is automatically moved to the replacement cassette (200) and stored, and at the same time, the unused carrier (110) is moved to the braider (100) and mounted.

[0105] Next, in the step (S40) of returning the branch track to its original position, when the carrier (110) replacement is completed, the branch track (300) returns to its initial set position and maintains a circular track for normal brading.

[0106] Next, in the step of connecting with the thread (S50), the thread fixed to the clamp and the thread of the carrier (110) before use are connected to form a single continuous thread. At this time, it is desirable to maintain the tension of the thread constant to ensure uniform braiding quality.

[0107] Finally, once the thread connection is complete, product production continues through the step of resuming braiding (S60).

[0108] Accordingly, the braider (100), composed of a carrier (110), a track plate (120), a braiding horn gear (130), a carrier replacement device (A), etc., can replace multiple carriers (110) simultaneously, thereby greatly increasing the efficiency of the braiding operation. This has the effect of reducing worker fatigue by reducing repetitive bobbin replacement work.

[0109]
