Description

[0001] This application claims priority to the patent application filed on November 11, 2024, with China National Intellectual Property Administration, application number 2024227521779, entitled "Cloth Storage Device and Tire Production System". Technical Field

[0002] This invention relates to the field of tire cord production equipment, and more specifically, to a tire cord storage method, a tire cord storage device, and a tire production system. Background Technology

[0003] In the manufacturing process of all-steel and semi-steel tires, the steel cord belt layer is one of the important components of the tire. The production of the belt layer requires cutting calendered steel cord fabric at the required angle, splicing the beveled edges, and then winding it up for forming and use. With the development of tire technology, the requirements for splicing efficiency and cord stretching of the belt layer are becoming increasingly stringent. The typical cutting angle range is 15-70 degrees. The maximum splicing efficiency reaches 20-24 pieces / minute. After splicing, the spliced ​​cord length is unloaded at high speed via a conveyor belt, and a cord length is approximately 2-4 meters. Therefore, a storage arc is usually required to store the unloading capacity of a cord length to meet the high-speed, intermittent unloading operation. This inevitably causes stretching of the cord after splicing.

[0004] Since the height of the conveyor belt for unloading at the joint is typically suitable for manual standing operation, approximately 0.8-1 meter, the traditional method involves digging a storage pit in the ground, usually about 2 meters deep, to accommodate the maximum length of a single fabric sheet. When using this method, the fabric stretches significantly due to the high-speed start-stop unloading action and its own weight. Generally, the larger the fabric angle and the heavier the fabric, the greater the stretch. Furthermore, the deep pit makes on-site construction and operation inconvenient. Further, a method has been developed that adds a sloping conveyor belt within the storage pit, with the conveyor belt installed vertically or at a slight incline, and magnets installed in sections beneath it. While this structure reduces fabric stretching compared to existing technologies, it still involves a vertical or near-vertical storage configuration, meaning the stretching caused by high-speed start-stop and the fabric's own weight remains significant.

[0005] Therefore, existing technologies suffer from problems such as the fabric being easily stretched when storing materials, and the deep pits causing inconvenience in on-site construction and operation. Summary of the Invention

[0006] The main objective of this invention is to provide a method for storing tire cord material, a tire cord material storage device, and a tire production system to solve the problems of easy stretching of the tire cord material during tire cord material storage in the prior art, as well as the inconvenience of on-site construction and operation caused by deep pits.

[0007] To achieve the above objectives, according to one aspect of the present invention, a method for storing fabric curtain material is provided, comprising: performing a splicing operation on the fabric curtain through a splicing assembly; performing a discharging operation and a storing operation on the fabric curtain through a fabric storage device; wherein, in the vertical direction, the storage height is less than the height of the splicing operation on the fabric curtain.

[0008] Furthermore, during the unloading and storage operations of the curtain fabric, the movement path of the curtain fabric is zigzag.

[0009] Furthermore, the conveying speed varies for different parts of the zigzag motion path corresponding to the fabric storage device.

[0010] Furthermore, during the unloading and storage operations, at least a portion of the fabric storage device first moves away from the joint assembly and then moves towards the joint assembly.

[0011] According to another aspect of the present invention, a fabric storage device is provided, comprising: a first conveying assembly having a first inlet end and a first outlet end, wherein the first inlet end is disposed near a connector assembly; a second conveying assembly having a second inlet end and a second outlet end, wherein the first conveying assembly and the second conveying assembly are spaced apart in the height direction; and a dragging assembly disposed between the first conveying assembly and the second conveying assembly in the height direction, wherein the dragging assembly has a third inlet end and a third outlet end, wherein the third inlet end is disposed near the first outlet end, the third outlet end is disposed near the first inlet end, and the third inlet end is movably disposed relative to the third outlet end and is capable of moving in a direction close to or away from the third outlet end.

[0012] Furthermore, the first conveying component and the second conveying component have the same conveying direction.

[0013] Furthermore, the first conveying component and the second conveying component are parallel to each other.

[0014] Furthermore, the first conveying assembly is parallel to the horizontal direction; or in the vertical direction, the first discharge end is located below the first feed end.

[0015] Furthermore, in the horizontal direction, the second feed end, the third feed end, and the third discharge end are all located between the first feed end and the first discharge end, and the third discharge end is closer to the first feed end than the second feed end.

[0016] Furthermore, the material dragging assembly includes: a guide section; a transmission section, which is movably disposed on the guide section and can move along the guide section; and multiple material dragging sections, which are spaced apart along the guiding direction of the guide section and connected to the transmission section respectively. The transmission section drives the material dragging sections to move and adjusts the interval between two adjacent material dragging sections. The two material dragging sections located at both ends of the multiple material dragging sections are respectively the third feed end and the third discharge end.

[0017] Furthermore, the fabric storage device also includes a first detection component, which is located below the guide section in the height direction.

[0018] Furthermore, the fabric storage device also includes a second detection component, which is positioned above the guide section in the height direction.

[0019] Furthermore, there is an installation gap between the first feed end and the connector assembly.

[0020] According to another aspect of the present invention, a tire production system is provided, including a joint assembly and the aforementioned cord storage device.

[0021] Applying the technical solution of this invention, the curtain fabric storage method in this application includes: splicing the curtain fabric using a splice assembly; unloading and storing the curtain fabric using a curtain fabric storage device; and in the vertical direction, the height of the splicing operation is less than the height of the storage operation. When storing the curtain fabric using this method, the storage height is less than the splicing height. Therefore, the curtain fabric is not placed downwards in this application, but rather stored above the storage device, effectively reducing the pulling on the curtain fabric due to its own weight during storage. Thus, the curtain fabric storage method in this application effectively solves the problems of easy stretching of the curtain fabric during storage in the prior art and the inconvenience of on-site construction and operation caused by deep pits.

[0022] The fabric storage device includes a first conveying assembly, a second conveying assembly, and a material dragging assembly. The first conveying assembly has a first inlet end and a first outlet end, with the first inlet end located near the connector assembly. The second conveying assembly has a second inlet end and a second outlet end, and the first and second conveying assemblies are spaced apart in the height direction. In the height direction, the material dragging assembly is located between the first and second conveying assemblies. The material dragging assembly has a third inlet end and a third outlet end, with the third inlet end located near the first outlet end and the third outlet end located near the first inlet end. The third inlet end is movably positioned relative to the third outlet end and can move in a direction close to or away from the third outlet end.

[0023] When using the fabric storage device of this application, the fabric can be conveyed to the second conveying component via the first conveying component and the dragging component. After the jointing component completes the jointing of the fabric, the fabric can be unloaded through the fabric storage device. As the length of the fabric entering the fabric storage device increases, the third feeding end of the dragging component can move away from the third discharging end. At this time, the length of the dragging component increases, thereby ensuring that the dragging component has a larger dragging area, and thus ensuring that the dragging component can support the fabric to prevent the fabric from sag and sticking due to gravity. When the tail joint position of the fabric gradually moves to the corresponding position of the jointing component, the third feeding end can move towards the third discharging end until the tail joint position of the fabric moves to the corresponding position of the jointing component, completing the unloading action of one fabric. After the jointing component completes the jointing operation between the tail of this fabric and the head of the subsequent fabric, the fabric storage device continues the above actions until the tail of the subsequent fabric moves to the corresponding position of the jointing component. Furthermore, since the first conveying component, the second conveying component, and the material dragging component are spaced apart in the vertical direction in this application, the production space can be effectively utilized. Therefore, the fabric storage device in this application effectively solves the problems of easy stretching of the fabric during fabric storage in the prior art and the inconvenience of on-site construction and operation caused by deep pits.

[0030] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0032] In this invention, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this invention.

[0033] To address the problems of easy stretching of the tire cord during tire cord storage in existing technologies and the inconvenience of on-site construction and operation caused by deep pits, this application provides a tire cord storage method, a tire cord storage device, and a tire production system.

[0034] The curtain fabric storage method in this application includes: splicing the curtain fabric using a splice assembly 20; unloading and storing the curtain fabric using a curtain fabric storage device; and, in the vertical direction, the storage height is less than the height of the splicing operation. When using this method to store the curtain fabric, the storage height is less than the height of the splicing operation, so the curtain fabric is not placed downwards but stored above the storage device. This effectively reduces the pulling on the curtain fabric caused by its own weight during storage. Therefore, the curtain fabric storage method in this application effectively solves the problems of easy stretching of the curtain fabric during storage in the prior art and the inconvenience of on-site construction and operation caused by deep pits.

[0035] Optionally, during the unloading and storage operations of the curtain fabric, the movement path of the curtain fabric is zigzag. That is to say, during the unloading and storage operations of the curtain fabric, the space occupied by the curtain fabric during storage can be reduced by adjusting the movement path of the curtain fabric, thereby achieving the effect of saving costs.

[0036] In one specific embodiment of this application, the conveying speed of different parts of the zigzag motion path corresponding to the curtain material storage device is different.

[0037] Optionally, during the unloading and storage operations, at least a portion of the fabric storage device first moves away from the joint assembly 20, and then moves towards the joint assembly 20. During fabric storage, the portion of the fabric after a joint on the fabric storage device decreases as the storage operation proceeds. Therefore, to prevent the fabric storage device from pulling on the fabric, it is necessary to ensure that a portion of the fabric storage device contracts as the portion of the fabric on the device decreases, and then returns to an extended state and contracts again during the transport of the next fabric, forming a reciprocating storage cycle. Therefore, in this application, the middle section of the zigzag movement path of the fabric storage device first extends away from the joint assembly 20 during the unloading and storage operations, and then contracts towards the joint assembly 20.

[0038] In the above embodiments, the fabric storage device includes a first conveying component 10, a second conveying component 30, and a material-dragging component 40, such that the first conveying component 10, the second conveying component 30, and the material-dragging component 40 each correspond to three different segments of a zigzag motion path. Therefore, the conveying speed or movement speed of the first conveying component 10, the second conveying component 30, and the material-dragging component 40 can be different. In this embodiment, the first conveying component 10 and the second conveying component 30 can convey the fabric without extending or retracting in the length direction. The material-dragging component 40 can convey the fabric by extending or retracting, thereby enabling at least a portion of the fabric storage device to first move away from the joint component and then move towards the joint component.

[0039] And, as Figure 3 As shown, the tire production system of this application has a joint assembly 20 and a cord storage device described below.

[0040] like Figure 1 and Figure 2As shown, the fabric storage device of this application includes a first conveying assembly 10, a second conveying assembly 30, and a material dragging assembly 40. The first conveying assembly 10 has a first inlet end 11 and a first outlet end 12, and the first inlet end 11 is disposed near the connector assembly 20; the second conveying assembly 30 has a second inlet end 31 and a second outlet end 32, and the first conveying assembly 10 and the second conveying assembly 30 are spaced apart in the height direction; in the height direction, the material dragging assembly 40 is disposed between the first conveying assembly 10 and the second conveying assembly 30, and the material dragging assembly 40 has a third inlet end 41 and a third outlet end 42, the third inlet end 41 is disposed near the first outlet end 12, the third outlet end 42 is disposed near the first inlet end 11, and the third inlet end 41 is movably disposed relative to the third outlet end 42 and can move in the direction of approaching or moving away from the third outlet end 42.

[0041] When using the fabric storage device of this application, the fabric can be conveyed to the second conveying component 30 through the first conveying component 10 and the dragging component 40. After the jointing component 20 completes the jointing of the fabric, the fabric can be unloaded through the fabric storage device. As the length of the fabric entering the fabric storage device increases, the third feeding end 41 of the dragging component 40 can move away from the third discharging end 42. At this time, the length of the dragging component 40 increases, thereby ensuring that the dragging component 40 can have a larger dragging area, and thus ensuring that the dragging component 40 can support the fabric to prevent the fabric from drooping under the action of gravity and causing the fabric to stick together. When the tail joint position of the fabric gradually moves to the corresponding position of the jointing component 20, the third feeding end 41 can move towards the third discharging end 42 until the tail joint position of the fabric moves to the corresponding position of the jointing component 20, and the unloading action of one fabric is completed. After the joint assembly 20 completes the jointing operation between the tail of this curtain and the head of the subsequent curtain, the curtain storage device continues the above-mentioned actions until the tail of the subsequent curtain moves to the corresponding position of the joint assembly 20. Furthermore, since the first conveying assembly 10, the second conveying assembly 30, and the material dragging assembly 40 are spaced apart in the vertical direction in this application, the production space can be effectively utilized. Therefore, the curtain storage device in this application effectively solves the problems of easy stretching of the curtain during material storage in the prior art and the inconvenience of on-site construction and operation caused by deep pits.

[0042] Of course, in this application, the tire production system may also include structures such as a film applicator, a winding device, and a slitting device located at the second discharge end 32, and may also include structures such as a cord opening device, a centering conveyor, a cutting device, a material pulling device, and a joint feeding conveyor belt located upstream of the joint assembly. The specific working methods are the same as those in the prior art, so they will not be described in detail here.

[0043] Furthermore, in this application, the conveying speed V1 of the first conveying component 10 is greater than the conveying speed V3 of the second conveying component 30. In a specific embodiment of this application, the speed at which the third feed end 41 moves relative to the third discharge section is V2, and V2 = (V1 - V3) / 2. Therefore, it is not difficult to find that when the curtain after the joint is unloaded by the curtain storage device in this application, when the first conveying component 10 and the second conveying component 30 convey the curtain, the speed at which the first conveying component 10 conveys the curtain is greater than the speed at which the second conveying component 30 conveys the curtain. Therefore, in the initial stage, in order to avoid the curtain between the first conveying component 10 and the second conveying component 30 from sticking together, the third feed end 41 needs to move in a direction away from the third discharge end 42, thereby avoiding the accumulation or stretching of the curtain. Meanwhile, in this application, the speed of V1 starts and stops synchronously with the connector assembly 20 at the front end, and is not affected by V2 and V3; the speed of V3 depends on the operation of the back-end equipment, operates independently, and is also not affected by V1 and V2; V2 serves as a speed transition between V1 and V3, and its speed relationship is: V2 = (V1 - V3) / 2. The speed of V2 is adjusted in real time by the servo motor controller according to the change in distance between the detection sensor and the storage arc.

[0044] Meanwhile, in this application, both the first conveying assembly 10 and the second conveying assembly 30 can be conveyor belts driven by motors. Of course, in this application, the first conveying assembly 10 and the second conveying assembly 30 can also be other structures with conveying functions, as long as they can convey the curtain fabric.

[0045] In other words, in this application, the minimum sum of the lengths of the material feeding assembly 40, the first conveying assembly 10, and the second conveying assembly 30 after the third feeding end 41 of the material feeding assembly 40 has moved a maximum distance away from the third discharging end 42 needs to be greater than the length of a sheet of fabric. Of course, in this application, the above length relationship can be adaptively adjusted according to the actual usage, as long as the fabric storage device in this application can meet the storage requirements at the fabric joint.

[0046] Specifically, the first conveying assembly 10 and the second conveying assembly 30 have the same conveying direction. In one specific embodiment of this application, the conveying directions of both the first conveying assembly 10 and the second conveying assembly 30 are horizontal or approximately horizontal. Simultaneously, the movement direction of the third feed end 41 relative to the third discharge end 42 is also horizontal.

[0047] Optionally, the first conveying assembly 10 and the second conveying assembly 30 are parallel to each other.

[0048] Preferably, the first conveying assembly 10 is parallel to the horizontal direction. Of course, in this application, the first conveying assembly 10 and the second conveying assembly 30 can also be approximately parallel to the horizontal direction. In this case, as an optional embodiment, the first discharge end 12 is located below the first feed end 11 in the vertical direction. This arrangement ensures the effective conveying of the fabric on the first conveying assembly 10 and the second conveying assembly 30. Furthermore, in this application, the arrangement of the first conveying assembly 10 and the second conveying assembly 30 can be adaptively adjusted according to actual usage.

[0049] Optionally, in the horizontal direction, the second feed end 31, the third feed end 41, and the third discharge end 42 are all located between the first feed end 11 and the first discharge end 12, and the third discharge end 42 is closer to the first feed end 11 than the second feed end 31.

[0050] Optionally, the material-carrying assembly 40 includes a guide portion 43, a transmission portion 44, and a material-carrying portion 45. The transmission portion 44 is movably mounted on the guide portion 43 and can move along the guide portion 43. Multiple material-carrying portions 45 are spaced apart along the guiding direction of the guide portion 43 and connected to the transmission portion 44 respectively. The transmission portion 44 drives the material-carrying portions 45 to move and adjusts the interval between adjacent material-carrying portions 45. The two material-carrying portions 45 located at both ends are respectively the third feed end 41 and the third discharge end 42. In a specific embodiment of this application, the guide portion 43 is a guide rail, while the transmission portion 44 can be a structure such as a hinged connecting plate, connecting rod, or connecting chain, thereby ensuring that the transmission portion 44 can extend and retract during its movement along the guide rail, thus enabling the movement of the material-carrying portion 45, i.e., the movement of the third feed end 41 relative to the third discharge end 42. Furthermore, in this application, the third discharge end 42 is a fixed end, while the third feed end 41 is a movable end. Meanwhile, in this embodiment, the multiple spaced-apart material-carrying sections 45 can be structures such as multiple spaced-apart transmission rollers or multiple spaced-apart transmission plates. Furthermore, in this application, the material-carrying assembly 40 also includes a drive motor 46 for driving the material-carrying sections 45, thereby providing power for the movement of the material-carrying sections 45. Of course, in this application, the drive motor 46 can also drive a transmission unit, thereby driving the material-carrying sections to move through the transmission unit.

[0051] Optionally, the fabric storage device further includes a first detection component 50, which is positioned below the guide portion 43 in the height direction. Furthermore, in this application, the first detection component 50 can be signal-connected to the drive motor of the material feeding assembly 40. The first detection component 50 is used to detect the position of the storage arc 70 formed by the fabric between the first conveying assembly 10 and the second conveying assembly 30, thereby allowing the drive motor to adjust the position of the third feed end 41 of the material feeding assembly 40 upon receiving the signal. In this application, the radius of the storage arc of the fabric is generally 200-400 mm.

[0052] Optionally, the first detection component 50 can be a displacement sensor, which converts the analog signal detected by the displacement sensor into a digital signal through the PLC analog input module, thereby realizing the detection of the distance change between the detection sensor and the storage arc.

[0053] Optionally, the fabric storage device further includes a second detection component 60, which is positioned above the guide portion 43 in the height direction. The second detection component 60 is primarily used in this application to detect the quality of the fabric joints, fabric width, and other parameters. Of course, depending on the actual usage, the second detection component 60 may not be included, or other detection structures may be added.

[0054] Optionally, there is an installation gap between the first feed end 11 and the connector assembly 20. This arrangement facilitates operation and maintenance by the operator between the first feed end 11 and the connector assembly 20.

[0055] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0056] The fabric storage device of this application includes a first conveying assembly 10, a second conveying assembly 30, and a material dragging assembly 40. The first conveying assembly 10 has a first inlet end 11 and a first outlet end 12, and the first inlet end 11 is disposed near the connector assembly 20; the second conveying assembly 30 has a second inlet end 31 and a second outlet end 32, and the first conveying assembly 10 and the second conveying assembly 30 are spaced apart in the height direction; in the height direction, the material dragging assembly 40 is disposed between the first conveying assembly 10 and the second conveying assembly 30, and the material dragging assembly 40 has a third inlet end 41 and a third outlet end 42, the third inlet end 41 is disposed near the first outlet end 12, the third outlet end 42 is disposed near the first inlet end 11, and the third inlet end 41 is movably disposed relative to the third outlet end 42 and can move in the direction of approaching or moving away from the third outlet end 42.

[0057] When using the fabric storage device of this application, the fabric can be conveyed to the second conveying component 30 through the first conveying component 10 and the dragging component 40. After the jointing component 20 completes the jointing of the fabric, the fabric can be unloaded through the fabric storage device. As the length of the fabric entering the fabric storage device increases, the third feeding end 41 of the dragging component 40 can move away from the third discharging end 42. At this time, the length of the dragging component 40 increases, thereby ensuring that the dragging component 40 can have a larger dragging area, and thus ensuring that the dragging component 40 can support the fabric to prevent the fabric from drooping under the action of gravity and causing the fabric to stick together. When the tail joint position of the fabric gradually moves to the corresponding position of the jointing component 20, the third feeding end 41 can move towards the third discharging end 42 until the tail joint position of the fabric moves to the corresponding position of the jointing component 20, and the unloading action of one fabric is completed. After the joint assembly 20 completes the jointing operation between the tail of this curtain and the head of the subsequent curtain, the curtain storage device continues the above-mentioned actions until the tail of the subsequent curtain moves to the corresponding position of the joint assembly 20. Furthermore, since the first conveying assembly 10, the second conveying assembly 30, and the material dragging assembly 40 are spaced apart in the vertical direction in this application, the production space can be effectively utilized. Therefore, the curtain storage device in this application effectively solves the problems of easy stretching of the curtain during material storage in the prior art and the inconvenience of on-site construction and operation caused by deep pits.
