Description

Technical Field

[0001] This invention relates to the field of roll material replenishment technology, and more specifically, to a roll material replenishment device. Background Technology

[0002] External yarn winding is a manufacturing process for fiber composite products. In this process, fiber raw materials are pre-wound in the form of yarn bundles onto a roll (which can be solid or tubular) to form a fiber roll. During the winding process, the fiber roll is first suspended, yarn bundles are drawn out and mixed with resin, and the yarn bundles are connected to the product through a series of devices. Then, the rotation of the product drives the fiber roll to rotate and release material, thus completing a series of winding processes to finish the product manufacturing.

[0003] However, at present, whenever the yarn bundle in a fiber roll is used up, a new fiber roll needs to be taken out from the inventory to replace it, which relies too much on manual operation and the fiber roll replacement efficiency is not high. Summary of the Invention

[0004] In view of at least one of the above-mentioned defects or deficiencies in the prior art, the present invention provides a roll material replenishment device that can store multiple spare roll materials in advance to speed up their use and avoid excessive reliance on manual replacement operations, thereby improving the efficiency of roll material replacement.

[0005] To achieve the above objectives, the present invention provides a roll material replenishment device, comprising:

[0006] The coil falling channel forms multiple coil placement positions at different heights. The lowest coil placement position is the placement position for use, and the remaining coil placement positions are all placement positions for backup.

[0007] An empty reel outlet is formed in the reel drop channel, and the empty reel outlet is connected to the placement and use position; and

[0008] The coil support assembly includes a use position support member disposed at the placement and use position and a plurality of spare position supports disposed one-to-one with a plurality of the placement spare positions. The spare position supports can be moved out of the corresponding placement spare position so that the spare coil originally supported by the spare position support member loses support and falls along the coil falling channel to the coil placement position below.

[0009] Optionally, the empty roll outlet is formed on the periphery of the roll falling channel and is disposed adjacent to the top of the placement and use position, and the use position support is elastically connected to the bottom wall of the roll falling channel.

[0010] The support member can gradually lift the supported and gradually consumed light roll material under the drive of elastic force, so that the remaining empty roll can eventually be lifted to be discharged from the empty roll outlet.

[0011] Optionally, the roll material replenishment device further includes a roll pusher, one end of which is elastically connected to the periphery of the roll material falling channel and the other end is formed as a pusher pressing end opposite to the empty roll outlet.

[0012] The use of the position support member can raise the unloaded reel to press against the pressing end of the pusher member, so that when the unloaded reel is raised to be located between the unloaded reel outlet and the pressing end of the pusher member, the reel pusher member can push the unloaded reel out of the unloaded reel outlet under the force of elastic drive.

[0013] Optionally, the top surface of the pusher crimping end is formed with a downward crimping slope that is inclined downward toward the empty spool outlet, and the bottom surface of the pusher crimping end is formed with an upward push crimping slope that is inclined upward toward the empty spool outlet.

[0014] The supporting member at the usage position can raise the unloaded reel to press against the outward pressing slope, so that the reel pusher can push the unloaded reel out of the unloaded reel outlet under the elastic drive; the reel pusher can move away from the unloaded reel outlet when the falling pressing slope is pressed by the falling reel material, so that the falling reel material can eventually fall into the placement and use position.

[0015] Optionally, the falling pressing slope is formed as a falling pressing surface that curves downward toward the empty reel outlet, and the acute angle between the falling pressing surface and the horizontal plane increases from top to bottom. The outward pressing slope is formed as an outward pressing surface that curves upward toward the empty reel outlet, and the acute angle between the outward pressing surface and the horizontal plane increases from bottom to top.

[0016] Optionally, the inner peripheral wall of the roll falling channel is formed with an outward pusher clearance groove, and the roll outward pusher is elastically connected to the side wall of the outward pusher clearance groove along the depth direction.

[0017] Optionally, the roll material supply device further includes a discharge outlet valve body and a valve body traction mechanism connecting the discharge outlet valve body and the roll pusher. The roll pusher can close the empty roll outlet by driving the discharge outlet valve body through the valve body traction mechanism when moving away from the empty roll outlet, or it can open the empty roll outlet by driving the discharge outlet valve body through the valve body traction mechanism when moving closer to the empty roll outlet.

[0018] Optionally, a valve body channel communicating with the empty roll outlet is formed in the peripheral wall of the roll falling channel. The outlet valve body is movably disposed in the valve body channel and can extend from the valve body channel to close the empty roll outlet.

[0019] Optionally, the coil feeding device further includes a support member traction mechanism, which includes a main traction module and multiple branch traction modules. The used position support member is connected to the main traction module, and the main traction module is connected to multiple spare position support members in a one-to-one correspondence through multiple branch traction modules.

[0020] The space support member can be used to gradually move each of the spare space support members out of the corresponding placement spare position through the support member traction mechanism during the lifting process, and to gradually move each of the spare space support members into the corresponding placement spare position through the support member traction mechanism during the lowering process.

[0021] Optionally, the spare position support is elastically connected to the periphery of the coil falling channel and can be moved into the corresponding placement spare position in a free-release state.

[0022] Optionally, the inner peripheral wall of the roll falling channel is formed with a plurality of support member avoidance grooves corresponding one-to-one with the plurality of spare position support members, and the spare position support member is elastically connected to the side wall of the corresponding support member avoidance groove along the depth direction.

[0023] Optionally, the roll material replenishment device further includes an empty roll discharge channel communicating with the empty roll discharge port.

[0024] Optionally, the top of the roll falling channel is formed with a roll filling inlet for replenishing the roll.

[0025] When using the roll material replenishment device of the present invention, on the one hand, the roll material in use can be supported in the placement and use position using the use position support member, and the winding process of the product can be performed by rotating and unloading the roll material. On the other hand, multiple spare roll materials can be pre-supported in multiple placement and spare positions using multiple spare position support members, and multiple spare roll materials can be centrally stored. When the material in the use roll material is exhausted and there is an empty roll remaining, the empty roll can be discharged out of the empty roll discharge port, so that the placement and use position is in an empty state. Each spare position support member is first moved out of the corresponding placement and spare position and then moved back in, so that each spare roll material can fall into the adjacent roll material placement position below. The spare roll material that falls into the placement and use position is then put into production as new use roll material. In this way, not only can multiple spare roll materials be centrally stored, but the use of spare roll materials in production can also be accelerated, reducing manual replacement operations and improving roll material replacement efficiency.

[0044] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of the present invention.

[0045] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0046] In the embodiments of the present invention, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used to describe the relative positional relationships of the components in relation to the directions shown in the accompanying drawings or in relation to the vertical, perpendicular, or gravitational directions.

[0047] The present invention will now be described in detail with reference to the accompanying drawings and exemplary embodiments.

[0048] like Figure 1 and Figure 2 As shown, an exemplary embodiment of the present invention provides a roll material replenishment device 100, which mainly includes a roll material falling channel 1 and a roll material support assembly.

[0049] Specifically, the roll material falling channel 1 has an empty roll outlet 1a and multiple roll material placement positions at different heights. The lowest roll material placement position is used for placing the working roll 200, while the remaining roll material placement positions are used for placing spare rolls 300. The empty roll outlet 1a is connected to the placement positions. When the working roll 200 is exhausted, leaving an empty roll 400, the empty roll 400 needs to be discharged outward through the empty roll outlet 1a, and is usually discharged to the waste area for unified collection. It can be seen that when using roll material to perform the winding process on the product, the material of the working roll 200 placed in the placement positions is consumed. After the working roll 200 is exhausted, an empty roll 400 is left. The spare roll 300 is the roll fully loaded with material. Before falling into the placement position, the spare roll 300 is not used in production. In addition, the roll of material can be solid or cylindrical.

[0050] To hold multiple rolls of material in their respective placement positions, a roll support assembly is required. This assembly includes a user position support 4 located at the user position and multiple backup position supports 5, each corresponding to a backup placement position. For the backup rolls 300 to fall along the roll descent channel 1, each backup position support 5 must be movable out of its corresponding backup placement position. In other words, when a backup position support 5 is moved into its corresponding backup placement position, it supports the backup roll 300 there. When the support 5 is moved out of its position, the backup roll 300 loses support and falls under its own weight along the roll descent channel 1 into the lower roll placement position.

[0051] It should be noted that when using the position support 4 and multiple spare position support 5 to support multiple rolls of material respectively, the support is specifically provided on the roll of material. Furthermore, the roll material drop channel 1 can be configured to allow only the two ends of the roll of material to pass through, or it can be configured to allow the entire roll of material to pass through. If the entire roll of material can pass through, when the roll of material is in the placement and use position for production, the outer wall of the roll material drop channel 1 needs to have a corresponding perforated position so that the material of the roll of material can be led out of the roll material supply device 100 through the perforated position. Similarly, the empty roll discharge port 1a can be configured to allow only the two ends of the empty roll 400 to pass through, or it can be configured to allow the entire empty roll 400 to pass through.

[0052] With the above configuration, the roll material replenishment device 100 of this exemplary embodiment can, on the one hand, use the use position support 4 to support the use roll material 200 in the placement and use position, and perform the winding process on the product by rotating and unloading the roll material 200. On the other hand, it can use multiple spare position support 5 to pre-support multiple spare roll materials 300 in multiple placement spare positions, and centrally store the multiple spare roll materials 300. When the material in the use roll material 200 is exhausted and there is an empty roll 400 remaining, the empty roll 400 can be discharged outside the empty roll discharge port 1a, so that the placement and use position is in an empty state. Each spare position support 5 is first moved out of the corresponding placement spare position and then moved back in, so that each spare roll material 300 can fall into the adjacent roll material placement position below. The spare roll material 300 that falls into the placement and use position is then put into production use as a new use roll material 200. In this way, not only can multiple spare rolls of material 300 be stored in a centralized manner, but the spare rolls of material 300 can also be put into production more quickly, reducing manual replacement operations and effectively improving the efficiency of roll replacement.

[0053] This exemplary embodiment does not limit the control methods for the displacement movement and timing of the aforementioned multiple spare position support members 5, and the outward discharge movement and timing of the unloaded roll 400. For example, it can be manually controlled, electrically controlled (requiring a human power source such as a motor, cylinder, or hydraulic cylinder), or even controlled solely by the connection method of the internal structure of the device in the absence of a human power source. Even with purely manual control, the roll material replenishment device 100 of this exemplary embodiment can save more time on manual roll material replacement and achieve higher roll material replacement efficiency compared to the prior art.

[0054] In an optional or preferred embodiment, a structure is provided that can automatically control the empty reel 400 to be discharged from the empty reel outlet 1a without a human power source. The core of this structure is to use the weight of the reel 200 itself as a control variable.

[0055] Specifically, refer to Figure 2An empty roll outlet 1a is formed on the periphery of the roll falling channel 1 and adjacent to the top of the placement and use position. The use position support 4 is elastically connected to the bottom wall of the roll falling channel 1, for example, by a first elastic element 7a of the type of spring or elastic sheet. When the use position support 4 supports the use roll 200 and the use roll 200 has not yet started to be consumed, the weight of the use roll 200 is relatively large, and the use position support 4 can be in a balanced state under the action of upward elastic force and the pressure applied by the use roll 200. As the use roll 200 gradually consumes material, the use roll 200 gradually becomes lighter. At this time, the upward elastic force on the use position support 4 is greater than the pressure applied by the use roll 200, and the use position support 4 can gradually lift the use roll 200. When the material in the use roll 200 is exhausted and an empty roll 400 remains, the use position support 4 can finally lift the empty roll 400 so that it can be discharged outward from the empty roll outlet 1a.

[0056] Obviously, as long as the upward elastic force on the support member 4 is set up in a reasonable way so that the variation law of the upward elastic force on the support member 4 matches the weight variation law of the coil 200, the dynamic process required above can be achieved.

[0057] As for how to ensure that the unloaded spool 400 is discharged outward from the unloaded spool outlet 1a, it can be achieved in different ways. For example, the support surface of the use position support 4 can be set as an inclined plane. When the unloaded spool 400 is raised to be level with or slightly higher than the unloaded spool outlet 1a, the unloaded spool 400 can roll out of the unloaded spool outlet 1a along the inclined plane under its own weight. When the use roll 200 is lower than the unloaded spool outlet 1a, the peripheral wall of the roll falling channel 1 can provide lateral restraint for the use roll 200. Therefore, even if the support surface of the use position support 4 is set as an inclined plane, it will not affect the use roll 200 from being placed in the use position.

[0058] The above-described method of setting the support surface of the position support member 4 as an inclined surface to ensure that the unloaded reel 400 is discharged outward from the unloaded reel outlet 1a is obviously not driven by a man-made power source, and therefore is still within the scope of the concept of this embodiment.

[0059] In an alternative or preferred embodiment, another method is provided to ensure that the unloaded reel 400 is discharged from the unloaded reel outlet 1a, which is also within the scope of the concept of driving without the aid of a man-made power source.

[0060] Specifically, the roll material replenishment device 100 also includes a roll pusher 6, one end of which is elastically connected to the peripheral wall of the roll material falling channel 1 (e.g., through a second elastic element 7b of the type of spring or elastic sheet), and the other end is formed as a pusher pressing end opposite to the empty roll outlet 1a. The position support 4 allows the empty roll 400 to be raised to the pressing end of the pusher under elastic force, and before the empty roll 400 is raised to a position between the empty roll outlet 1a and the pusher pressing end, ... Figure 2 For example, the rightward pressure on the reel pusher 6 is greater than the leftward elastic force, so the reel pusher 6 will move away from the empty reel outlet 1a. Once the empty reel 400 is raised to a position between the empty reel outlet 1a and the pusher pressing end, due to the loss of the lateral limiting effect of the peripheral wall of the reel falling channel 1, the reel pusher 6 can push the empty reel 400 out of the empty reel outlet 1a under the drive of the leftward elastic force.

[0061] For the above dynamic process, as long as it is reasonably set so that the change law of the upward elastic force on the support member 4 is similar to that of the leftward elastic force on the roll push member 6 (with... Figure 2 Taking the example, the variation pattern conforms to a certain matching relationship, which can ensure that the unloaded reel 400 can still be raised to the position between the unloaded reel outlet 1a and the external pusher pressing end when the external pusher pressing end is pressed.

[0062] Obviously, in this embodiment, no artificial power source is used to drive the unloaded reel 400 to discharge outward from the unloaded reel outlet 1a.

[0063] In an optional or preferred embodiment, refer to Figure 2 and Figure 3 The top surface of the pusher end has a downward pressing slope 6a that slopes downward toward the empty spool outlet 1a, and the bottom surface of the pusher end has an upward pressing slope 6b that slopes upward toward the empty spool outlet 1a. When the empty spool 400 is raised to press the pusher end, the empty spool 400 is actually pressed against the pressing slope 6b. Due to the presence of the pressing slope 6b, the upward elastic force borne by the support member 4 can be more effectively converted into the rightward pressure borne by the pusher 6. Figure 2 (For example), thus better ensuring that the drive reel pusher 6 moves away from the empty reel outlet 1a. When a spare reel 300 placed in the spare placement position adjacent to the placement and use position needs to be added to the empty placement and use position, the falling spare reel 300 will first press against the falling pressing slope 6a. Since the spare reel 300 is fully loaded with material and has a large weight, the rightward pressure on the reel pusher 6 at this time is greater than the leftward elastic force (for example). Figure 2For example, the roll pusher 6 can move in a direction away from the empty roll outlet 1a to avoid the falling spare roll 300 and ensure that it can eventually fall into the placement and use position.

[0064] Furthermore, continue to refer to Figure 2 and Figure 3 The falling pressing slope 6a is formed as a falling pressing surface that bends downward toward the empty roll outlet 1a. The acute angle between the falling pressing surface and the horizontal plane increases from top to bottom. That is, as the spare roll 300 presses against the falling pressing surface and falls continuously, the angle α between the tangent at the contact point P1 of the spare roll 300 and the falling pressing surface and the horizontal plane gradually increases. And from the force analysis, it can be seen that F1' = F1sinα (where F1 is the pressure exerted by the spare roll 300 on the roll pusher 6, and F1' is the horizontal component of F1, that is, the rightward pressure borne by the roll pusher 6 at this time). It can be seen that the rightward pressure F1' borne by the roll pusher 6 will gradually increase as the spare roll 300 falls continuously. Therefore, it can be ensured that the roll pusher 6 keeps moving in the direction away from the empty roll outlet 1a. Furthermore, the outward pressing inclined surface 6b is formed as an outward pressing curved surface that curves upward toward the empty spool outlet 1a. The acute angle between the outward pressing curved surface and the horizontal plane increases from bottom to top. That is, as the empty spool 400 presses against the outward pressing curved surface and is continuously raised, the angle β between the tangent at the contact point P2 of the empty spool 400 and the outward pressing curved surface and the horizontal plane gradually increases. And from the force analysis, it can be seen that F2'=F2sinβ (where F2 is the pressure exerted by the empty spool 400 on the spool pusher 6, and F2' is the horizontal component of F2, that is, the rightward pressure that the spool pusher 6 bears at this time). It can be seen that the rightward pressure F2 that the spool pusher 6 bears will gradually increase as the empty spool 400 continues to rise. Therefore, it can be ensured that the spool pusher 6 continues to move in a direction away from the empty spool outlet 1a.

[0065] In an optional or preferred embodiment, the inner peripheral wall of the roll falling channel 1 is formed with an outward pusher clearance groove 1b, at which time the roll outward pusher 6 is elastically connected to the side wall of the outward pusher clearance groove 1b along the depth direction. When the roll outward pusher 6 clears the falling spare roll 300, the roll outward pusher 6 extends into the outward pusher clearance groove 1b, and in the free release state without elastic force, the pressing end of the outward pusher extends out of the groove of the outward pusher clearance groove 1b, ensuring that it can be pressed against the raised unloaded rotating shaft 400.

[0066] In an optional or preferred embodiment, the roll material replenishment device 100 further includes a discharge outlet valve body 8 and a valve body traction mechanism 9 connecting the discharge outlet valve body 8 and the roll pusher 6. During the process of the roll pusher 6 moving away from the empty roll outlet 1a, i.e., before the roll pusher 6 pushes the empty spool 400 towards the empty roll outlet 1a, the roll pusher 6 can drive the discharge outlet valve body 8 to close the empty roll outlet 1a via the valve body traction mechanism 9. This prevents the roll material 200 from being prematurely pushed out of the empty roll outlet 1a before it is raised to a position close to the pressing end of the pusher and before the material is exhausted, thus avoiding material waste. Furthermore, during the process of the reel pusher 6 approaching the empty reel outlet 1a, that is, during the process of the reel pusher 6 pushing the empty shaft 400 toward the empty reel outlet 1a, the reel pusher 6 can drive the outlet valve body 8 to open the empty reel outlet 1a through the valve body traction mechanism 9, ensuring that the empty shaft 400 can eventually be pushed out of the empty reel outlet 1a.

[0067] In an optional or preferred embodiment, a valve body channel 3 communicating with the empty roll outlet 1a is formed within the peripheral wall of the roll falling channel 1. The outlet valve body 8 is movable within the valve body channel 3. When it is necessary to close the empty roll outlet 1a, the outlet valve body 8 extends from the valve body channel 3 to the empty roll outlet 1a. When it is necessary to open the empty roll outlet 1a, the outlet valve body 8 moves entirely into the valve body channel 3.

[0068] In an optional or preferred embodiment, a structure is provided that can automatically control each spare position support 5 to move into or out of the corresponding placement spare position without a human power source. Its core is also to use the weight of the roll material 200 itself as a control variable.

[0069] Specifically, the roll material replenishment device 100 also includes a support member traction mechanism, which includes a main traction module 10 and multiple branch traction modules 11. The working position support 4 is connected to the main traction module 10, and the main traction module 10 is connected one-to-one with multiple standby position support 5s via the multiple branch traction modules 11. When the working position support 4 gradually rises under elastic drive as the working roll material 200 it supports gradually becomes lighter due to wear, the working position support 4 can drive each standby position support 5 to gradually move out of its corresponding standby position through the support member traction mechanism. When the working position support 4 gradually descends due to supporting new working roll material 200, the working position support 4 can drive each standby position support 5 to gradually move into its corresponding standby position through the support member traction mechanism. This configuration not only directly links the material consumption of the working roll material 200 with the timing of the descent of the multiple standby roll materials 300, but also directly links the timing of the replenishment of new working roll material 200 into the working position with the timing of the multiple standby roll materials 300 regaining support.

[0070] In this embodiment, ideally, when the material in the roll 200 is completely exhausted, the remaining empty roll 400 immediately begins to discharge from the empty roll discharge outlet 1a. Simultaneously, each spare position support 5 completely moves out of its corresponding spare position, allowing each spare roll 300 to begin falling. That is, the discharge of the empty roll 400 and the falling of each spare roll 300 are essentially synchronized, further shortening the replacement time of each roll and, in particular, further improving the replacement efficiency of the roll 200.

[0071] Furthermore, before the bottommost spare roll 300 falls into the empty placement and use position and presses against the use position support 4, it must be ensured that none of the other spare rolls 300 have fallen into the adjacent placement spare positions below. Otherwise, the falling spare rolls 300 may not be supported because the adjacent spare position support 5 below has not had time to be moved back into the corresponding placement spare position, and thus continue to fall. This would result in multiple spare rolls 300 being supported on some spare position support 5 that have been moved back into the placement spare positions, affecting the normal placement of the spare rolls 300, and in particular, it may affect the normal use of the new use rolls 200.

[0072] In an optional or preferred embodiment, to improve the response speed of each spare position support 5 repositioning into its corresponding spare position, and to avoid the situation where the falling spare roll 300 is not supported because the adjacent spare position support 5 below has not had time to reposition into its corresponding spare position, the spare position support 5 can be configured to be elastically connected to the periphery of the roll falling channel 1 (for example, through a third elastic element 7c of the type of spring, elastic sheet, etc.), and the spare position support 5 can be moved into its corresponding spare position in a free-release state (i.e., without being subjected to elastic force). In this way, the spare position support 5 can pre-bear a reset elastic force when it is moved out of its corresponding spare position by the support member traction mechanism, thereby accelerating the reset speed under the drive of the reset elastic force when it is moved back into its corresponding spare position, ensuring timely support for the falling spare roll 300.

[0073] In an optional or preferred embodiment, the inner peripheral wall of the roll material falling channel 1 is formed with a plurality of support member avoidance grooves 1c corresponding one-to-one with a plurality of spare position support members 5. At this time, the spare position support member 5 is elastically connected to the side wall of the corresponding support member avoidance groove 1c along the depth direction. When the spare position support member 5 moves out of the corresponding placement spare position, the spare position support member 5 extends into the support member avoidance groove 1c, so that the spare roll material 300 originally supported by it can fall. In the free release state without being subjected to elastic force, the spare position support member 5 extends out of the slot of the support member avoidance groove 1c and is located in the corresponding placement spare position, ensuring that it can support the spare roll material 300.

[0074] In an optional or preferred embodiment, the roll material supply device 100 further includes an empty roll discharge channel 2 connected to the empty roll discharge outlet 1a. The empty roll 400 that discharges from the empty roll discharge outlet 1a then enters the empty roll discharge channel 2 and can roll along the empty roll discharge channel 2 to the waste area for unified collection.

[0075] In an optional or preferred embodiment, a roll material replenishment inlet 1d is formed at the top of the roll material drop channel 1 for replenishing roll material. When the uppermost spare placement position is vacant, spare roll material 300 can be replenished through the roll material replenishment inlet 1d, and the replenished spare roll material 300 can fall along the roll material drop channel 1 onto the spare placement support 5 located at the uppermost position.

[0076] In summary, the roll replenishment device 100 of this exemplary embodiment is suitable for fields where materials are consumed by rotating the roll to wind products, such as the field of fiber composite material product manufacturing, and is especially suitable for the field of fiber composite material product manufacturing that mainly uses external drawing resin winding process.

[0077] When the roll replenishment device 100 is applied in the field of manufacturing fiber composite materials products mainly using the external drawing resin winding process, the aforementioned roll 200 and spare roll 300 are both fiber rolls. The fiber rolls are formed by orderly winding fiber raw materials in the form of yarn bundles onto a roll (which can be solid or tubular).

[0078] In the manufacturing of fiber composite products, which primarily utilizes the external drawing and resin winding process, several or even dozens of fiber rolls are typically required to mix and wind the product. Workers must not only oversee product production but also monitor the consumption of all fiber rolls and replace them promptly. Failure to replace a fiber roll after it has run out of material poses a risk of substandard product quality. However, because the yarn bundle lengths of each fiber roll are not perfectly consistent, over long-term production, the remaining material in each roll will vary. It is difficult for workers to completely avoid missing replacements by simply observing the rolls. Once a replacement is missed, workers must stop the machine to re-wind the yarn bundles, thus impacting production efficiency and increasing costs.

[0079] To address the aforementioned issues, the solutions described in the previous embodiments, such as automatically controlling the empty roll 400 to discharge from the empty roll outlet 1a without a human power source and automatically controlling the movement of each spare support 5 into or out of its corresponding spare placement position, can be combined. By utilizing the weight of the used roll 200 itself as a control variable, the automatic and timely replacement of old and new used rolls 200 can be achieved. This completely avoids missed roll replacements, reduces worker workload, minimizes downtime, thereby improving production efficiency, reducing costs, and optimizing product quality.
