Description

Technical Field

[0001] This invention relates to the field of textile equipment, and in particular to a yarn rack with a prompting function and its yarn loading process. Background Technology

[0002] A knitting machine is a textile device that uses knitting needles to form loops of yarn of various colors, and then connects them into knitted fabrics. The yarn required by the knitting machine during the textile process is provided by yarn bobbins. Nowadays, yarn bobbins are generally hung on yarn racks. During the operation of the textile machine, the rotating yarn bobbins can continuously supply yarn to the racks.

[0003] Currently, yarn bobbins are generally hung on yarn racks manually. The yarn rack consists of multiple support rods, each with multiple bobbin rods for hanging yarn bobbins. During the hanging process, workers need to hang the yarn bobbins of the corresponding colors on the corresponding bobbin rods according to the pattern and color. However, due to the large number of bobbin rods, workers can easily mix up the positions of the corresponding bobbin rods when entering the yarn rack to load yarn bobbins, thus hanging the wrong color yarn bobbins on the bobbin rods and causing quality problems in the fabric.

[0004] Based on this, the present invention provides a yarn rack with a prompting function and its yarn loading process, which indicates the color of the yarn tube that should be hung on each yarn tube rod, so as to avoid workers hanging the wrong yarn tube. Summary of the Invention

[0005] Therefore, it is necessary to provide a yarn rack with a prompting function, including a frame, in which several support rods are vertically arranged in a rectangular array. Several yarn bobbin rods for hanging yarn bobbins are provided on the support rods. The ends of the yarn bobbins away from the support rods are inclined upwards. A limiting part for supporting the yarn bobbin is also provided on the support rod corresponding to the yarn bobbin rod. The limiting part is located above the end of the corresponding yarn bobbin rod facing the support rod. When the yarn bobbin is hung on the yarn bobbin rod, the end of the yarn bobbin facing the support rod abuts against the limiting part. At this time, the area of ​​the yarn bobbin rod surrounded by the yarn bobbin is the initial hanging section. A color-changing indicator light is embedded on the surface of the initial hanging section of the yarn bobbin rod.

[0006] In this invention, an inclined yarn bobbin rod is used to hang yarn bobbins. After the yarn bobbin is sleeved on the rod and hung there, it slides down along the rod's inclination until its left end abuts against a limiting part. This ensures that the yarn bobbin's position on the rod is fixed, i.e., the yarn bobbin is fixed to the initial hanging section of the rod. A color-changing indicator light on the rod indicates the color of the yarn bobbin that should be hung on it. For example, if the indicator light is red, a red yarn bobbin should be hung on that rod; if it is green, a green yarn bobbin should be hung. Therefore, during the hanging process, operators can easily identify the color of the yarn bobbin to be hung on the rod based on the color of the indicator light, effectively preventing incorrect yarn bobbin color placement. The color-changing indicator light can be an LED color-changing light.

[0007] In addition, since the color-changing indicator light is embedded on the surface of the initial tube hanging section of the yarn bobbin rod, when the yarn bobbin is hung on the corresponding yarn bobbin rod, the color-changing indicator light on the yarn bobbin rod will be covered by the yarn bobbin. Therefore, after the yarn bobbin is hung, the operator can quickly check whether there is a yarn bobbin that has been missed by observing whether the color-changing indicator light on the yarn bobbin rod is not covered. This allows for convenient and quick inspection of the yarn bobbin hanging status.

[0008] Furthermore, the upper end of the yarn tube rod forms a support surface that matches the inner wall of the yarn tube and is used to fit against the inner wall of the yarn tube, and the color-changing indicator light is embedded in the support surface.

[0009] In this invention, after the yarn bobbin is hung on the yarn bobbin rod, the upper surface of the inner side wall of the yarn bobbin will be in contact with the support surface. At this time, there is no gap between the yarn bobbin and the support surface, which can effectively prevent the light emitted by the color-changing indicator light from leaking out from both ends of the yarn bobbin. Thus, after the yarn bobbin is hung on the yarn bobbin rod, the operator cannot see the light emitted by the color-changing indicator light on the yarn bobbin rod. At this time, it means that the yarn bobbin rod has been hung with the yarn bobbin. It can be seen that this invention can prevent light from leaking out from both ends of the yarn bobbin and affecting the operator's observation of the luminous status of the color-changing indicator light on the yarn bobbin rod.

[0010] In addition, the yarn tubes hanging on the yarn tube rod can completely block the light from the yarn tube rod. Therefore, after the yarn tubes are hung on the yarn tube rod, the presence of the yarn tubes can prevent the yarn tube rod where they are located from emitting light, thereby avoiding interference with the operator's observation of the color-changing indicator light color and light status on other yarn tube rods.

[0011] Furthermore, a light-blocking plate is also provided on the support rod corresponding to the color-changing indicator light on the yarn tube rod, and the light-blocking plate is located behind the corresponding color-changing indicator light.

[0012] In this invention, the rear side of the color-changing indicator light refers to the side of the color-changing indicator light away from the frame where the operator can enter. The light-blocking plate set on the rear side of the color-changing indicator light can block the color-changing indicator light behind the current color-changing indicator light, thereby reducing the number of color-changing indicator lights that the operator sees at one time and effectively preventing the operator from getting dizzy due to seeing too many light-emitting color-changing indicator lights.

[0013] Furthermore, the light-blocking plate is white.

[0014] In this invention, the white light-blocking plate can display the color of the color-changing indicator light on its front side when the light from the color-changing indicator light shines on it, which helps the operator to distinguish the color of the color-changing indicator light on the yarn bobbin rod.

[0015] Furthermore, the limiting part includes a limiting rod disposed on the support rod. The limiting rod and the corresponding yarn bobbin rod are located in the same vertical plane. The end of the limiting rod away from the support rod is inclined upward, and the inclination of the limiting rod is greater than the inclination of its corresponding yarn bobbin rod.

[0016] In this invention, after the yarn bobbin is hung on the yarn bobbin rod, it slides down along the inclination of the rod until the left end of the bobbin abuts against the lower surface of the limiting rod. At this point, the bobbin is in the initial hanging section on the yarn bobbin rod. As the bobbin continuously supplies yarn to the knitting machine, its diameter gradually decreases. During this process, the bobbin continues to slide along the inclination of the yarn bobbin rod to always abut against the lower surface of the limiting rod. Therefore, when the diameter of the bobbin decreases to a certain extent, the bobbin moves away from the color-changing indicator light, removing the obstruction to the indicator light. That is, in this invention, when the yarn on the bobbin is consumed to a certain extent, the light of the corresponding color-changing indicator light on the yarn bobbin rod can be observed by the operator again, which can serve as a reminder to the operator that the yarn on the current bobbin is about to be consumed.

[0017] Furthermore, the limiting rod is movably mounted on the support rod.

[0018] In this invention, by adjusting the height of the limiting rod, the position of the yarn bobbin on the yarn bobbin rod when it rests against the limiting rod can be changed, thus changing the position of the initial hanging section on the yarn bobbin rod. This results in different distances the yarn bobbin needs to move to expose the color-changing indicator light. For example, if the height of the limiting rod is increased, the initial hanging section on the yarn bobbin rod will shift a certain distance towards the support rod, allowing the yarn bobbin to move a shorter distance to expose the color-changing indicator light. Conversely, if the height of the limiting rod is decreased, the initial hanging section on the yarn bobbin rod will shift a certain distance away from the support rod, requiring the yarn bobbin to move a greater distance to expose the color-changing indicator light. In other words, by adjusting the height of the limiting rod, the diameter of the yarn bobbin that needs to be reduced to expose the color-changing indicator light can be adjusted, thereby adjusting the amount of yarn remaining on the yarn bobbin when the color-changing indicator light is exposed.

[0019] Furthermore, a mounting groove is provided on the side wall of the support rod facing the limiting rod, and a mounting plate is provided in the mounting groove in a height-reducible manner. The end of the limiting rod facing the support rod is fixedly mounted on the mounting plate.

[0020] In this invention, the limiting rod can be moved up and down on the support rod by moving the mounting plate up and down.

[0021] Furthermore, a cylinder is also provided in the mounting groove. The cylinder is located above the mounting plate and is drivenly connected to the mounting plate to drive the mounting plate to move up and down. A slide rod is also fixedly provided at the lower end of the mounting plate. An insertion hole is opened at the bottom of the mounting groove corresponding to the slide rod. The slide rod is inserted into the insertion hole. The outer side wall of the slide rod and the inner side wall of the insertion hole are fitted together and slidably matched.

[0022] In this invention, the mounting plate is driven by a cylinder to move up and down. The sliding rod at the lower end of the mounting plate is inserted into the insertion hole and can support the mounting plate to prevent the support plate from deflecting during the up and down movement, thereby preventing the limit rod from deflecting during the up and down movement.

[0023] In addition, the present invention also provides a yarn loading process for the above-mentioned yarn rack with a prompting function, comprising the following steps:

[0024] S1. Obtain textile process information and design the color of the yarn tubes to be hung on each yarn tube rod in the frame according to the pattern and color of the fabric.

[0025] S2. Make the color-changing indicator lights on each yarn bobbin rod in the frame light up, and make the light color consistent with the color of the yarn bobbin to be hung on the yarn bobbin rod;

[0026] S3. Based on the color-changing indicator light on the yarn bobbin rod, hang the yarn bobbin with the same color as the color-changing indicator light on the yarn bobbin rod.

[0027] Furthermore, in step S2, the frame is divided into multiple partitions, namely the first partition, the second partition, ... the Nth partition, wherein the color-changing indicator lights in the first partition, the second partition, ... the Nth partition light up rapidly in sequence according to the order of the first partition, the second partition, ... the Nth partition.

[0028] The system ensures that the color-changing indicator lights in the first, second, ... Nth zones illuminate sequentially according to the zone's order. Then, the operator enters the corresponding illuminated zone in the order of illumination to hang the yarn bobbins. At this time, the color-changing indicator lights in other zones, except for the zone where the operator is located, are not illuminated, thus eliminating the influence of illuminated color-changing indicator lights in other zones on the identification of the color-changing indicator lights in the current zone.

[0029] The principles and effects of the present invention will be further explained below with reference to the above technical solutions and accompanying drawings:

[0030] In this invention, during the process of hanging yarn bobbins, operators can easily distinguish the color of the yarn bobbin to be hung on the bobbin rod based on the color-changing indicator light, effectively avoiding the situation of hanging the wrong color of yarn bobbin. The color-changing indicator light can be an LED color-changing light.

[0031] In addition, since the color-changing indicator light is embedded on the surface of the initial tube hanging section of the yarn bobbin rod, when the yarn bobbin is hung on the corresponding yarn bobbin rod, the color-changing indicator light on the yarn bobbin rod will be covered by the yarn bobbin. Therefore, after the yarn bobbin is hung, the operator can quickly check whether there is a yarn bobbin that has been missed by observing whether the color-changing indicator light on the yarn bobbin rod is not covered. This allows for convenient and quick inspection of the yarn bobbin hanging status. Attached Figure Description

Detailed Implementation

[0039] To facilitate understanding by those skilled in the art, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments:

[0040] like Figure 1-5 A yarn rack with a prompting function includes a frame 1. Several support rods 2 are vertically arranged within the frame 1 in a rectangular array. Several yarn tube rods 3 for hanging yarn tubes 7 are provided on each support rod 2. The end of each yarn tube rod 3 away from the support rod 2 is inclined upwards. A limiting part for supporting the yarn tube 7 is also provided on each support rod 2 corresponding to the yarn tube rod 3. The limiting part is located above the end of the corresponding yarn tube rod 3 facing the support rod 2. When the yarn tube 7 is hung on the yarn tube rod 3, the end of the yarn tube 7 facing the support rod 2 abuts against the limiting part. At this time, the area of ​​the yarn tube rod 3 surrounded by the yarn tubes 7 is the initial hanging section. A color-changing indicator light 5 is embedded on the surface of the initial hanging section of the yarn tube rod 3.

[0041] In this invention, the inclined yarn tube rod 3 is used to hang the yarn tube 7. After the yarn tube 7 is sleeved on the yarn tube rod 3 and hung on the yarn tube rod 3, it will slide down along the inclination of the yarn tube rod 3 until the left end of the yarn tube 7 abuts against the limiting part, so that the position of the yarn tube 7 hanging on the yarn tube rod 3 is fixed, that is, the yarn tube 7 will be fixed on the initial hanging section of the yarn tube rod 3. The color-changing indicator light 5 on the yarn tube rod 3 is used to indicate the color of the yarn tube 7 that should be hung on the yarn tube rod 3 by its light color. For example, if the light color of the color-changing indicator light 5 is red, then the yarn tube 7 should be hung on the yarn tube rod 3. If the light color of the color-changing indicator light 5 is green, then the yarn tube 7 should be hung on the yarn tube rod 3. Therefore, during the process of hanging the yarn tube 7, the operator can easily distinguish the color of the yarn tube 7 that needs to be hung on the yarn tube rod 3 according to the color of the color-changing indicator light 5 on the yarn tube rod 3, which can effectively avoid the situation of hanging the wrong color of the yarn tube 7. Among them, the color-changing indicator light 5 can be an LED color-changing light.

[0042] In addition, since the color-changing indicator light 5 is embedded on the surface of the initial tube hanging section of the yarn tube rod 3, when the yarn tube 7 is hung on the corresponding yarn tube rod 3, the color-changing indicator light 5 on the yarn tube rod 3 will be covered by the yarn tube 7. Therefore, after the yarn tube 7 is hung, the operator can quickly check whether the yarn tube rod 3 has missed hanging the yarn tube 7 by observing whether the color-changing indicator light 5 on the yarn tube rod 3 is not covered. This allows for convenient and quick inspection of the hanging status of the yarn tube 7.

[0043] In one embodiment, the upper end of the yarn tube rod 3 forms a support surface 31 that matches the inner sidewall of the yarn tube 7 and is used to fit against the inner sidewall of the yarn tube 7. The color-changing indicator light 5 is embedded in the support surface 31.

[0044] In this embodiment, after the yarn tube 7 is hung on the yarn tube rod 3, the upper surface of the inner side wall of the yarn tube 7 will be in contact with the support surface 31. At this time, there is no gap between the yarn tube 7 and the support surface 31, which can effectively prevent the light emitted by the color-changing indicator light 5 from leaking out from both ends of the yarn tube 7. Thus, after the yarn tube 7 is hung on the yarn tube rod 3, the operator cannot see the light emitted by the color-changing indicator light 5 on the yarn tube rod 3. At this time, it means that the yarn tube 7 has been hung on the yarn tube rod 3. It can be seen that the present invention can prevent light from leaking out from both ends of the yarn tube 7 and affecting the operator's observation of the light emission of the color-changing indicator light 5 on the yarn tube rod 3.

[0045] In addition, the yarn tube 7 hanging on the yarn tube rod 3 can completely block the light on the yarn tube rod 3. Therefore, after the yarn tube 7 is hung on the yarn tube rod 3, the presence of the yarn tube 7 can prevent the yarn tube rod 3 where it is located from emitting light, thereby avoiding interference with the operator's observation of the color-changing indicator light 5 on other yarn tube rods 3 and the light emission status.

[0046] In one embodiment, a light-blocking plate 6 is also provided on the support rod 2 corresponding to the color-changing indicator light 5 on the yarn tube rod 3, and the light-blocking plate 6 is located behind the corresponding color-changing indicator light 5.

[0047] In this embodiment, the rear side of the color-changing indicator light 5 refers to the side of the color-changing indicator light 5 away from the frame 1 where the operator can enter. The light-blocking plate 6 set on the rear side of the color-changing indicator light 5 can block the color-changing indicator light 5 behind the current color-changing indicator light 5, thereby reducing the number of color-changing indicator lights 5 that the operator can see at one time, and effectively preventing the operator from being dizzy due to seeing too many light-emitting color-changing indicator lights 5.

[0048] In one embodiment, the light-blocking plate 6 is white.

[0049] In this embodiment, the white light-blocking plate 6 can display the light color of the color-changing indicator light 5 on its front side when the light of the color-changing indicator light 5 shines on it, which helps the operator to distinguish the color of the color-changing indicator light 5 on the yarn tube rod 3.

[0050] In one embodiment, the limiting part includes a limiting rod 4 disposed on the support rod 2. The limiting rod 4 and the corresponding yarn bobbin rod 3 are located in the same vertical plane. The end of the limiting rod 4 away from the support rod 2 is inclined upward, and the inclination of the limiting rod 4 is greater than the inclination of its corresponding yarn bobbin rod 3.

[0051] In this embodiment, after the yarn bobbin 7 is sleeved on the yarn bobbin rod 3 and hung on the yarn bobbin rod 3, it will slide down along the inclination of the yarn bobbin rod 3 until the left end of the yarn bobbin 7 abuts against the lower end surface of the limiting rod 4. At this time, the yarn bobbin 7 is located in the initial hanging section on the yarn bobbin rod 3. As the yarn bobbin 7 continuously supplies yarn to the knitting machine, the diameter of the yarn bobbin 7 will gradually decrease. During this process, the yarn bobbin 7 will continue to slide along the inclination of the yarn bobbin rod 3 to always abut against the lower end surface of the limiting rod 4. Therefore, when the diameter of the yarn bobbin 7 decreases to a certain extent, the yarn bobbin 7 will move away from the color-changing indicator light 5, releasing the obstruction of the color-changing indicator light 5. That is, in this invention, when the yarn on the yarn bobbin 7 is consumed to a certain extent, the light of the corresponding color-changing indicator light 5 on the yarn bobbin rod 3 can be observed by the operator again, which can serve to remind the operator that the yarn on the current yarn bobbin 7 is about to be consumed.

[0052] In one embodiment, the limiting rod 4 is movably mounted on the support rod 2.

[0053] In this embodiment, by adjusting the height of the limiting rod 4, the position of the yarn bobbin 7 on the yarn bobbin rod 3 when it rests against the limiting rod 4 can be changed, that is, the position of the initial hanging section on the yarn bobbin rod 3 can be changed. At this time, the distance that the yarn bobbin 7 needs to move to expose the color-changing indicator light 5 on the yarn bobbin rod 3 is different. For example, if the height of the limiting rod 4 is increased, the initial hanging section on the yarn bobbin rod 3 will be offset towards the support rod 2 by a certain distance. At this time, the yarn bobbin 7 only needs to move a shorter distance on the yarn bobbin rod 3 to expose the color-changing indicator light 5. If the height of the limiting rod 4 is decreased, the initial hanging section on the yarn bobbin rod 3 will be offset away from the support rod 2 by a certain distance. At this time, the yarn bobbin 7 only needs to move a farther distance on the yarn bobbin rod 3 to expose the color-changing indicator light 5. That is, by adjusting the height of the limiting rod 4, the diameter of the yarn bobbin 7 that needs to be reduced to expose the color-changing indicator light 5 can be adjusted, thereby adjusting the yarn allowance on the yarn bobbin 7 when the color-changing indicator light 5 is exposed.

[0054] In one embodiment, the support rod 2 has an installation groove 21 on the side wall facing the limiting rod 4, and an installation plate 22 is provided in the installation groove 21 in a height-reducible manner. The end of the limiting rod 4 facing the support rod 2 is fixedly installed on the installation plate 22.

[0055] In this embodiment, the limiting rod 4 can be moved up and down on the support rod 2 by moving the mounting plate 22 up and down.

[0056] In one embodiment, a cylinder 23 is also provided in the mounting groove 21. The cylinder 23 is located above the mounting plate 22 and is drivenly connected to the mounting plate 22 to drive the mounting plate 22 to move up and down. A slide rod 24 is also fixedly provided at the lower end of the mounting plate 22. An insertion hole 25 is opened at the bottom of the mounting groove 21 corresponding to the slide rod 24. The slide rod 24 is inserted into the insertion hole 25. The outer side wall of the slide rod 24 and the inner side wall of the insertion hole 25 are fitted together and slidably matched.

[0057] In this embodiment, the mounting plate 22 is driven by the cylinder 23 to move up and down. The slide rod 24, which is located at the lower end of the mounting plate 22, is inserted into the insertion hole 25 and can support the mounting plate 22 to prevent the support plate from deflecting during the up and down movement, thereby preventing the limit rod 4 from deflecting during the up and down movement.

[0058] In addition, the present invention also provides a yarn loading process for the above-mentioned yarn rack with a prompting function, comprising the following steps:

[0059] S1. Obtain textile process information and design the color of the yarn cylinder 7 to be hung on each yarn cylinder rod 3 in the frame 1 according to the pattern and color of the fabric.

[0060] S2. Make the color-changing indicator lights 5 on each yarn bobbin rod 3 in the frame 1 light up, and make the light color consistent with the color of the yarn bobbin 7 to be hung on the yarn bobbin rod 3;

[0061] S3. Based on the color-changing indicator light 5 on the yarn tube rod 3, hang the yarn tube 7, whose color is the same as the color-changing indicator light 5 on the yarn tube rod 3, on the yarn tube rod 3.

[0062] In one embodiment, in step S2, the frame 1 is divided into multiple partitions, namely the first partition a, the second partition b, ... the Nth partition n, wherein the color-changing indicator lights 5 in the first partition a, the second partition b, ... the Nth partition n light up rapidly and sequentially in the order of the first partition a, the second partition b, ... the Nth partition n.

[0063] In this embodiment, the color-changing indicator lights 5 in the first partition a, the second partition b, ... the Nth partition n light up sequentially according to the order of the partitions. Then, the operator enters the corresponding lit partition according to the lighting order to hang the yarn bobbin 7. At this time, except for the partition where the operator is located, the color-changing indicator lights 5 in other partitions do not light up, which can eliminate the influence of the lit color-changing indicator lights 5 in other partitions on the identification of the color-changing indicator lights 5 in the current partition.

[0064] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
