Description

Technical Field

[0001] This invention belongs to the field of fabric rolling equipment, specifically an automatically guided rollerless fabric rolling device and a fabric rolling method. Background Technology

[0002] The fabric winding machine is part of the circular knitting machine and is located below the circular knitting machine. After the knitting machine finishes weaving, the fabric is wound up by the fabric winding machine. The fabric is then wound onto the rollers and transported to the storage area, and then transferred to other areas for processing.

[0003] Traditional fabric rolling equipment typically uses rollers for rolling fabric. After each roll, new rollers need to be continuously added to the equipment. Furthermore, the rollers remain in place throughout subsequent transfers, uses, and processing of the fabric. After use, the rollers also need to be recycled, significantly increasing workload. In addition to adding rollers after each roll, workers also need to rewrap the cut edges of the previous roll onto new rollers, which is time-consuming, labor-intensive, and inefficient, and needs improvement. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an automatically guided rollerless fabric winding device and method.

[0005] The present invention adopts the following technical solution:

[0006] An automatically guided rollerless fabric winding device, located below the fabric outlet, includes a support frame, a winding roller, a drive roller assembly, a lifting mechanism, a feeding mechanism, a cutting mechanism, and a guiding mechanism.

[0007] The supports are symmetrically arranged on both sides of the fabric outlet;

[0008] The fabric roll includes two telescopic rollers that are arranged opposite each other on the support. The fabric is wound around the fabric roll to form a roll. The telescopic rollers can extend in the opposite direction to the roll state where they are joined together or retract in the opposite direction to the feeding state.

[0009] The drive roller assembly is located below the fabric roll roller. The fabric passes between the fabric roll roller and the drive roller assembly and is driven forward by the drive roller assembly.

[0010] The lifting mechanism is mounted on the bracket and connected to the fabric rolling roller, driving the two telescopic rollers to lift synchronously.

[0011] The feeding mechanism pushes the fabric roll to one side and out of the equipment;

[0012] The cutting mechanism is located at the equipment outlet to cut the fabric;

[0013] The guiding mechanism includes a guide plate and a first cylinder. The guide plate is located between the cutting mechanism and the drive roller group and is flipped on the bracket. It can be flipped from a guiding state close to the roll roller and the drive roller group to a storage state away from the roll roller and the drive roller group. When the guide plate rotates from the storage state to the guiding state, it flips and transports the fabric cut by the cutting mechanism to the roll roller and rewraps it on the roll roller. The first cylinder is connected to the guide plate and drives it to rotate.

[0014] Preferably, the fabric rolling roller further includes a telescopic roller, a telescopic mechanism, and a fixing mechanism. The telescopic roller consists of multiple rollers nested in sequence. The telescopic mechanism is located within the telescopic roller to drive its extension and retraction. It includes an air nozzle, an air pipe, and a rotary joint. The air nozzle is located on the inner wall of the roller and connected to a sealed space. Several air pipes are provided, each corresponding to an air nozzle, with the other end extending to the end of the roller. The rotary joint is located at the end of the outermost roller and connects to both the air pipe and an external air supply device. The fixing mechanism is located at the end of the innermost roller of the telescopic roller to engage the two telescopic rollers.

[0015] Preferably, the fixing mechanism includes a male connector and a female connector, which are respectively disposed at the ends of the telescopic rollers on both sides. The male connector is disposed at the innermost sleeve end of one telescopic roller and is shaped as a frustum extending outward and gradually decreasing in diameter. The female connector is disposed at the innermost sleeve end of the other telescopic roller and has a groove that is recessed inside to match the shape of the male connector.

[0016] Preferably, the telescopic roller further includes a limiting section recessed inward at the front end of the roller and a snap-fit ​​section protruding outward at the end of the roller. The limiting section of the outer roller contacts the snap-fit ​​section of the inner roller to limit the movement range of the inner roller. A plurality of sealing spaces are formed between the limiting section of the outer roller and the snap-fit ​​section of the inner roller. The inner diameter of the limiting section is equal to the outer diameter of the snap-fit ​​section it contacts. The inner side of the limiting section is recessed inward to form a first annular groove, and the outer side of the snap-fit ​​section is recessed inward to form a second annular groove. Sealing rings are provided in the first annular groove and the second annular groove. The sealing rings contact the roller wall and are located on both sides of the sealing space to seal the sealing space.

[0017] Preferably, the lifting mechanism includes a rodless cylinder, a connecting plate, a guide rod, and a guide block. The rodless cylinder is mounted on the bracket and parallel to the lifting direction of the fabric roll. The connecting plate connects the rodless cylinder and the fabric roll to drive the fabric roll to lift. The guide rod is mounted on the bracket and parallel to the rodless cylinder. The guide block is slidably mounted on the guide rod and connected to the connecting plate.

[0018] Preferably, the feeding mechanism includes a push rod, an extension rod, and a second cylinder. The push rod is rotatably mounted on the bracket and can be rotated from the side away from the drive roller group to the side close to the drive roller group. The extension rod is formed at the end of the push rod and extends along the direction close to the fabric roll. The extension rod can be rotated with the push rod to the top of the drive roller group to push the fabric roll on the drive roller group forward. The second cylinder is mounted on the bracket to drive the push rod to rotate.

[0019] Preferably, the feeding mechanism further includes an unwinding assembly for receiving the fabric roll pushed out by the push rod. The unwinding assembly includes a receiving rail, an extension seat, a flipping rod, and a driving component. The receiving rail extends along the fabric roll output direction, and the top surface of the receiving rail is an inclined surface that slopes forward along the output direction. The extension seat is disposed in the receiving rail and can move back and forth along the fabric roll movement direction. The flipping rod is rotatably disposed at the front end of the extension seat and can rotate from a vertical state that blocks the fabric roll from moving forward to a horizontal state. The driving component is connected to the extension seat and the flipping rod respectively and drives the extension seat to extend and drives the flipping rod to rotate.

[0020] Preferably, the cutting mechanism includes a slide rail and a fabric cutter. The slide rail is arranged on the receiving rail perpendicular to the direction of fabric roll movement. The fabric cutter is movably mounted on the slide rail for cutting the fabric. The guide plate is an arc-shaped plate adapted to the fabric roll. The guide plate is in a retracted state and is mounted on the receiving rail between the slide rail and the drive roller group. The guide plate is formed with clearance holes corresponding to the receiving rail, allowing the receiving rail to pass through.

[0021] Preferably, the bracket is formed with a sliding groove that extends along the movement trajectory of the end of the flipping rod, and the end of the flipping rod extends into the sliding groove and moves within the sliding groove.

[0022] A fabric winding method, based on an automatically guided rollerless fabric winding device as described in any one of the above claims, characterized in that it includes:

[0023] Step 1: Drive the two telescopic rollers to extend to the mating state of the rolled fabric. The lifting mechanism drives the rolled fabric rollers to descend to the bottom and close to the drive roller group. The first cylinder drives the guide plate to rotate to the storage state.

[0024] Step 2: The fabric falls from the top of the equipment, and the guide roll enters between the roll roller and the drive roller group. The drive roller group drives the fabric forward, and the fabric moves forward to the top of the guide plate.

[0025] Step 3: Drive the guide plate to flip to the fabric roll state, flip the fabric and wrap it around the fabric roll roller. After the fabric roll is completely wrapped around the fabric roll roller, drive the first cylinder to reset so that the first guide plate rotates to the storage state.

[0026] Step 4: The lifting mechanism drives the fabric roll roller to rise as the diameter of the fabric roll on the roll increases. After the fabric roll is completed, the driving roller group is stopped, and the telescopic roller is controlled to retract to both sides until the telescopic roller is disengaged from the fabric roll feeding state, thus obtaining a rollless fabric roll placed on the driving roller group.

[0027] Step 5: The feeding mechanism pushes the rollless fabric on the drive roller group forward to move out of the equipment, and the cutting mechanism cuts the fabric.

[0028] Step six: Repeat steps three through five, rolling the fabric repeatedly until it is completely rolled up.

[0029] As can be seen from the above description of the present invention, compared with the prior art, the beneficial effects of the present invention are: by using a retractable fabric rolling roller, the fabric roll is contracted to both sides after the fabric is rolled to obtain a roll without roller shaft, and by rotating the guide plate, the fabric is moved forward by the drive roller group and moved upward by the guide plate and automatically wound on the fabric rolling roller, which improves the automation of the fabric rolling device, reduces the workload, and improves production efficiency.

[0030] The telescopic roller is extended and retracted through the air passage, and the rotating joint facilitates the rotation of the fabric roll roller with the fabric roll action, and can also better drive the fabric roll roller to rise as the fabric roll diameter increases.

[0031] When the telescopic roller extends, it is fixedly connected to the female connector through the male connector to avoid damage to the roll roller due to the increased weight and pressure of the fabric roll as it becomes larger.

[0032] The limiting section and the snap-fit ​​section prevent the rollers from separating from each other, and the sealing ring is set to ensure the airtightness of the inside of the telescopic roller, thereby improving the stability of the telescopic roller's extension and contraction.

[0033] After the fabric roll is completed, the roll is pushed forward by the feeding mechanism to complete the feeding process.

[0034] After the fabric roll is fed, it falls onto the receiving track. The movement of the fabric roll is restricted by the vertical state of the flipping rod. Then, the extension seat moves forward and pushes the fabric roll forward in a horizontal state, making it easy to send the fabric roll forward out of the equipment.

[0035] The guide plate is an arc-shaped plate located between the slide rail and the drive roller group. It can drive the cut fabric to flip upward and rewrap on the roll roller. In the storage state, in order to prevent the fabric roll from falling into the guide plate and being stuck by the guide plate during the roll feeding, which would cause the roll feeding failure, the guide plate is provided with a clearance hole for the receiving track to pass through, so that the guide plate can rotate to the bottom of the receiving track without affecting the roll feeding.

[0036] The groove provides support for the tilting rod, improving structural strength. Attached Figure Description

Detailed Implementation

[0050] The present invention will be further described below through specific embodiments.

[0051] Example 1:

[0052] Reference Figures 1 to 11 As shown, an automatically guided rollerless fabric rolling device includes a support 1, a rolling roller 2, a drive roller group 3, a lifting mechanism 4, a feeding mechanism 5, a cutting mechanism 6, and a guiding mechanism 7.

[0053] The bracket 1 is symmetrically arranged on both sides of the fabric outlet.

[0054] The fabric roll 2 includes a telescopic roller 21, a telescopic mechanism 22, and a fixing mechanism 23. The fabric is wound around the fabric roll 2 to form a roll.

[0055] Two telescopic rollers 21 are provided, arranged opposite each other along the coaxial line. They can extend in opposite directions to a mating roll state or retract in opposite directions to a feeding roll state. The telescopic roller 21 includes a plurality of rollers 211 nested in sequence, a limiting section 212 recessed inward at the front end of the roller 211, and a locking section 213 protruding outward at the end of the roller. The limiting section 212 of the outer roller 211 contacts the locking section 213 of the inner roller 211 to limit the movement range of the inner roller 211, and a plurality of sealing spaces 214 are formed between the limiting section 212 of the outer roller 211 and the locking section 213 of the inner roller 211.

[0056] Specifically, the inner diameter of the limiting section 212 is equal to the outer diameter of the snap-fit ​​section 213 that contacts it. The inner side of the limiting section 212 is recessed to form a first annular groove 215, and the outer side of the snap-fit ​​section 213 is recessed to form a second annular groove 216. A sealing ring 217 is provided in the first annular groove 215 and the second annular groove 216. The sealing ring 217 contacts the wall of the roller 211 and is located on both sides of the sealing space 214 to seal the sealing space 214. By providing sealing rings 217 on both sides of the sealing space 214, the airtightness of the sealing space 214 is ensured, and the stability of the extension and retraction of the telescopic roller 21 is guaranteed.

[0057] Furthermore, the length of roller 211 decreases sequentially from the inside to the outside. A limiting ring 218 is provided on the outer surface of roller 211. The outer diameter of the limiting ring 218 is larger than the inner diameter of the outer roller 211 to limit the movement range of the inner roller 211. The inner diameter of the outer roller 211 is larger than the outer diameter of the locking section 213 of the inner roller 211. The inner diameter of the limiting section 212 of the outer roller 211 is larger than the diameter of the inner roller 211 but smaller than the outer diameter of the locking section 213 of the inner roller 211, thus limiting the bidirectional movement range of roller 211 and preventing the inner roller 211 from detaching or excessively extending into the outer roller 211. The limiting section 212 on the roller 211 located in the middle position is integrally formed with the limiting ring 218, extending from the end of roller 211 to both sides. Only the limiting section 212 and the limiting ring 218 are formed on the outermost roller 211.

[0058] Preferably, the limiting section 212 is provided with a plurality of limiting posts 219. The limiting posts 219 are evenly distributed circumferentially on the limiting section 212 and face the inside of the roller 211. The contact surface between the limiting posts 219 and the snap-fit ​​section 213 is provided with a rubber sleeve for cushioning, thereby improving service life. The ends of the limiting posts 219 can contact the snap-fit ​​section 213 to support the sealing space 214.

[0059] The telescopic mechanism 22 is installed in the telescopic roller 21 to drive the telescopic roller 21 to extend and retract. It includes an air nozzle 221, an air pipe 222, and a rotary joint 223. Two air nozzles 221 are provided, symmetrically distributed on the inner wall of the roller 211 and connected to the sealed space 214. The air pipe 222 is connected to each air nozzle 221 in a corresponding manner, with the other end extending to the end of the roller 211. The rotary joint 223 is located at the end of the outermost roller 211, connecting to both the air pipe 222 and an external air supply device. The limiting post 219 supports the sealed space 214, preventing the sealed space 214 from becoming too small after the limiting section 212 and the locking section 213 are completely pressed together, thus preventing air from passing through the air nozzle 221 and causing the telescopic roller 21 to retract. This improves the operational stability of the telescopic roller 21. Specifically, the rotary joint 223 is a common rotary air passage joint in the prior art, capable of rotating while transmitting air. It is not the focus of this application, and its structure and selection will not be further elaborated here. Meanwhile, the arrangement of the air pipes is adapted to local conditions, and is arranged according to the different lengths of the telescopic roller 211. During the winding state, the air pipe 221 is folded and stored inside the roller 211. The length of the roller 211 is shortened from the outside to the inside to avoid the air nozzle being blocked by the inner roller 211 during the winding state.

[0060] A fixing mechanism 23 is located at the innermost end of the telescopic roller 211 to engage the two telescopic rollers 21. The fixing mechanism 23 includes a male connector 231 and a female connector 232, which are respectively located at the ends of the two telescopic rollers 21. The male connector 231 is located at the innermost sleeve end of one telescopic roller 21, and is shaped as a frustum extending outwards with a gradually decreasing diameter. The female connector 232 is located at the innermost sleeve end of the other telescopic roller 21, and has a recessed groove that matches the shape of the male connector 231. When the two telescopic rollers 21 extend, they are connected through the male connector 231 and the female connector 232, ensuring that the telescopic rollers 21 provide adequate support during fabric winding.

[0061] The drive roller group 3 is located below the roll roller 2. The fabric passes between the roll roller 2 and the drive roller group 3 and is driven forward by the drive roller group 3. The drive roller group 3 is arranged in a slightly downward direction along the output direction of the fabric roll, with an inclination angle of no more than 15°. This serves to place the fabric roll and also facilitates pushing the completed fabric roll outward.

[0062] The lifting mechanism 4 is mounted on the support 1 and connected to the fabric roll 2, driving the two telescopic rolls 21 to lift synchronously. It includes a rodless cylinder 41, a connecting plate 42, a guide rod 43, and a guide block 44. The rodless cylinder 41 is mounted on the support 1 and parallel to the lifting direction of the fabric roll 2. The connecting plate 42 connects the rodless cylinder 41 and the fabric roll 2, driving the fabric roll 2 to lift. The guide rod 43 is mounted on the support 1 and parallel to the rodless cylinder 41. The guide block 44 is slidably mounted on the guide rod 43 and connected to the connecting plate 42. Specifically, the rodless cylinder 41 and the guide rod 43 are located on opposite sides of the fabric roll 2 to ensure uniform force distribution on both sides of the connecting plate 42. If they are located on the same side and the force distribution is unbalanced, it can easily lead to increased friction between the guide block 44 and the guide rod 43, making it difficult to lift the fabric roll 2.

[0063] The feeding mechanism 5 pushes the fabric roll to one side out of the equipment. The feeding mechanism 5 includes a push rod 51, an extension rod 52, a second cylinder 53, and an unwinding assembly 54. The push rod 51 is rotatably mounted on the support 1, and can be flipped from the side away from the drive roller group 3 to the side close to the drive roller group 3. The extension rod 52 is formed at the end of the push rod 51 and extends along the direction close to the fabric roll. The extension rod 52 can be flipped with the push rod 51 above the drive roller group 3 to push the fabric roll on the drive roller group 3 forward. The second cylinder 53 is mounted on the support 1 to drive the push rod 51 to rotate. The unwinding assembly 54 can receive the fabric roll pushed out by the push rod 51, including… The system comprises a fabric receiving track 541, an extension seat 542, a flipping rod 543, and a driving component. The fabric receiving track 541 extends along the fabric roll output direction, and its top surface is an inclined surface that slopes forward along the output direction. The extension seat 542 is disposed within the fabric receiving track 541 and can move back and forth along the fabric roll movement direction. The flipping rod 543 is rotatably disposed at the front end of the extension seat 542 and can rotate from a vertical state that blocks the forward movement of the fabric roll to a horizontal state. The driving component is connected to both the extension seat 542 and the flipping rod 543, driving the extension seat 542 to extend and the flipping rod 543 to rotate. Specifically, a groove 11 is formed on the support 1, extending along the movement trajectory of the end of the flipping rod 543. The end of the flipping rod 543 extends into and moves within the groove 11, providing support for the flipping rod 543 and improving structural strength.

[0064] The cutting mechanism 6 is located at the equipment outlet to cut the fabric. The cutting mechanism 6 includes a slide rail 61 and a fabric cutter 62. The slide rail 61 is arranged on the receiving track 541 perpendicular to the direction of fabric roll movement. The fabric cutter 62 is movably mounted on the slide rail 61 for cutting the fabric. The fabric cutter 62 is a common fabric cutting device in the prior art and is not the focus of this application. Its structure and selection will not be further described here.

[0065] The guiding mechanism 7 includes a guide plate 71 and a first cylinder 72. The guide plate 71 is located between the cutting mechanism 6 and the drive roller group 3, and is rotatably mounted on the bracket 1. It can be rotated from a guiding state close to the fabric roll roller 2 and the drive roller group 3 to a storage state away from the fabric roll roller 2 and the drive roller group 3. When the guide plate 71 rotates from the storage state to the guiding state, it flips and transports the fabric cut by the cutting mechanism 6 onto the fabric roll roller 2 for rewinding. The first cylinder 72 is connected to the guide plate 71 and drives its rotation. By rotating the guide plate 71, the fabric moves forward via the drive roller group 3 and upward via the guide plate 71, automatically winding onto the fabric roll roller 2. This improves the automation of the fabric rolling process, reduces workload, and increases production efficiency.

[0066] Specifically, the guide plate 71 is an arc-shaped plate adapted to the fabric roll 2. In its retracted state, the guide plate 71 is mounted on the fabric receiving track 541, located between the slide rail 61 and the drive roller group 3. The guide plate 71 has a clearance hole 73 corresponding to the fabric receiving track 541, allowing the track to pass through. The arc-shaped guide plate 71, located between the slide rail 61 and the drive roller group 3, can cause the cut fabric to flip upwards and rewrap around the fabric roll 2. In its retracted state, to prevent the fabric roll from falling onto the guide plate 71 and getting stuck during feeding, thus preventing feeding failure, the clearance hole 73 on the guide plate 71 allows the guide plate 71 to rotate below the fabric receiving track 541 without affecting feeding.

[0067] A fabric winding method relates to the aforementioned automatically guided rollerless fabric winding device, comprising:

[0068] Step 1: Before rolling the fabric, drive the two telescopic rollers 21 to extend to the rolling state where the male connector 231 and the female connector 232 are connected. The lifting mechanism 4 drives the rolling roller 2 to descend to the bottom and get close to the drive roller group 3. The first cylinder 72 drives the guide plate 71 to rotate to the storage state.

[0069] Step 2: The fabric falls from the top of the equipment and is guided to pass between the roll roller 2 and the drive roller group 3. The drive roller group 3 starts to work and drives the fabric forward. The fabric moves forward to above the guide plate 71.

[0070] Step 3: Drive the first cylinder 72 to work and drive the guide plate 71 to flip to the roll state. The fabric flips with the guide plate 71 and wraps around the roll roller 2. After the fabric roll is completely wrapped around the roll roller 2, drive the first cylinder 72 to reset and rotate the first guide plate 71 to the storage state.

[0071] Step 4: The lifting mechanism 4 drives the fabric roll 2 to rise as the diameter of the fabric roll on the fabric roll 2 increases. After the fabric roll is completed, the driving roller group 3 is stopped, and the telescopic roller 21 is controlled to retract to both sides until the telescopic roller 21 is disengaged from the fabric roll feeding state, thus obtaining a rollless fabric roll placed on the driving roller group 3.

[0072] Step 5: The second cylinder 53 drives the push rod 51 to rotate and approach the drive roller group 3. The extension rod 52 contacts and pushes the rollerless fabric roll on the drive roller group 3 forward and into the receiving track 541 as the push rod 51 rotates. At this time, the unwound fabric moves forward with the rollerless fabric roll to above the slide rail 61. After the fabric is cut by the fabric cutter 62 moving on the slide rail 61, the extension seat 542 is driven to extend and the flipping rod 543 is controlled to rotate from the vertical state to the horizontal state to output the rollerless fabric roll outward.

[0073] Step six: Repeat steps three through five, rolling the fabric repeatedly until it is completely rolled up.

[0074] Example 2:

[0075] like Figure 12 As shown, the difference between this embodiment and Embodiment 1 is that the guide plate 71 has a protrusion on the side close to the fabric roll 2 that matches the surface of the fabric roll 2. The thickness of the protrusion gradually increases from both sides inward to match the diameter of the fabric roll 2. Since the telescopic roller 21 of the fabric roll 2 is composed of several sequentially nested rollers 211, the diameter of the fabric roll 2 gradually decreases from both sides inward. With the guide plate matching its shape, the fabric can be better adhered to the fabric roll 2.

[0076] This application utilizes a retractable fabric roll 2, which retracts to both sides after fabric rolling to obtain a roll without rollers. The rotation of the guide plate 71 causes the woven fabric to move forward via the drive roller group 3 and upward via the guide plate 71, automatically winding it onto the fabric roll 2. This improves the automation of fabric rolling, reduces workload, eliminates the need for repeated addition of rollers and recycling of rollers, simplifies production steps, and improves production efficiency.

[0077] The above description is merely a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of the patent application and the contents of the specification of the present invention should still fall within the scope of the patent of the present invention.
