Description

Technical Field

[0001] This invention relates to the field of tire tread feeding technology, and more specifically, to an auxiliary machine side feeding device and auxiliary machine side feeding method. Background Technology

[0002] The auxiliary steel tire side-feeding materials include: #1 belt layer, #2 belt layer, #3 belt layer, #4 belt layer, #0 belt layer, and tread material. Belt layers #1-4 are automatically cut and bonded. The all-steel tire zero belt (i.e., #0 belt layer) is mostly manually cut; the material is rolled and wound onto a feeding trolley, and fed from above the belt layer during bonding. The all-steel tread is mostly pre-cut; to achieve automated feeding, a van is used as the tooling trolley, and the bonding template is positioned above the belt layer during feeding.

[0003] The existing solution provides a zero-belt feeder above the 1-4# belt layer feeder, with the tread feeder positioned in front of the belt layer drum. This method requires a separate bonding and rotating drive device for the zero-belt feeder during bonding, resulting in a complex structure and high cost. Tread feeding, located in front of the belt layer drum, typically employs both manual and automatic bonding methods. Manual bonding relies entirely on manual operation; the large size and weight of the tread layer lead to high labor intensity for manual handling. Automatic bonding, on the other hand, occupies a large space and is also costly.

[0004] Some solutions involve providing a tread feeder above the 1-4# belt layer feeder, while in this case, the zero belt feeder is usually eliminated. This results in the same machine being unable to meet the production process of multiple tire specifications and the requirement for simultaneous bonding of the zero belt and tread. Summary of the Invention

[0005] The main objective of this invention is to provide an auxiliary machine side feeding device and auxiliary machine side feeding method to solve the problems of complex structure and high cost of the auxiliary machine side feeding device in the prior art.

[0006] To achieve the above objectives, according to one aspect of the present invention, an auxiliary machine-side feeding device is provided, comprising: a frame, a tread feeding template, a zero-track feeding template, and a tread / zero-track driving mechanism. The tread feeding template is movably connected to the frame; the zero-track feeding template is movably connected to the frame and moves synchronously with the tread feeding template in at least one direction; the tread / zero-track driving mechanism is driven connected to both the tread feeding template and the zero-track feeding template, and is capable of driving both the tread feeding template and the zero-track feeding template to move synchronously in at least one direction.

[0007] Furthermore, both the tread feeding template and the zero-belt feeding template can be raised and lowered relative to the frame, and the tread and zero-belt drive mechanism can drive the tread feeding template and the zero-belt feeding template to rise and fall synchronously.

[0008] Furthermore, the tread feeding template is located above the zero-belt feeding template.

[0009] Furthermore, the auxiliary machine side feeding device also includes a belt layer feeding template, which is located below both the tread feeding template and the zero belt feeding template.

[0010] Furthermore, the tread material supply template, the zero-belt material supply template, and the belt layer material supply template are set sequentially from top to bottom.

[0011] Furthermore, the tread feeding template and / or zero-belt feeding template include: a pre-feeding template, a bonding template, and a bonding drive component. The pre-feeding template is vertically adjustable relative to the frame; the bonding template is movably connected to the pre-feeding template and is laterally movable relative to the pre-feeding template; the bonding drive component is drivenly connected to the bonding template and is capable of driving the bonding template to move laterally to approach or move away from the belt drum.

[0012] Furthermore, the tread feeding template and / or zero-belt feeding template also include a post-feeding template. Along the material conveying direction, the post-feeding template is farther away from the belt drum than the pre-feeding template. The post-feeding template has a floating tensioning mechanism, and the material is conveyed around the floating tensioning mechanism. The floating tensioning mechanism is movable to control the tension of the material.

[0013] According to another aspect of the present invention, an auxiliary machine-side material feeding method is provided, employing the aforementioned auxiliary machine-side material feeding device. The auxiliary machine-side material feeding method includes: selecting the rubber compound bonding sequence according to the tire formula, and bonding the rubber compound sequentially according to the bonding sequence; when it is necessary to bond the tread or zero strip, the tread and zero strip driving mechanism drives the tread material feeding template and the zero strip material feeding template, so that the tread material feeding template and the zero strip material feeding template move synchronously to a predetermined position, and then the tread material feeding template or the zero strip material feeding template moves to bond the tread or zero strip.

[0014] Furthermore, the auxiliary machine side feeding method also includes: when the tread zero-belt drive mechanism drives the tread feeding template and the zero-belt feeding template to move synchronously, the tread zero-belt drive mechanism drives the tread feeding template and the zero-belt feeding template to move up and down synchronously, so that the tread feeding template and the zero-belt feeding template move to a predetermined height position, and then the tread feeding template or the zero-belt feeding template moves to perform rubber material bonding.

[0015] Furthermore, the auxiliary machine side feeding method also includes: when it is necessary to bond the belt layer, the belt layer feeding template is switched to the bonding state to bond the belt layer; when bonding one of the tread, the zero belt, and the belt layer, the bonding templates corresponding to the other two of the tread, the zero belt, and the belt layer are prepared with at least one of the following: cutting, centering, length measurement and heating.

[0016] Furthermore, the auxiliary machine side feeding method also includes: when the tread feeding template or the zero-belt feeding template moves to bond the rubber material, the floating tensioning mechanism moves to prevent the rubber material from being stretched, and the bonding drive drives the bonding template to move laterally and approach the belt layer drum to bond the rubber material; after bonding is completed, the bonding drive drives the bonding template to move laterally in the opposite direction and away from the belt layer drum, while the floating tensioning mechanism moves, and the tread zero-belt drive mechanism drives the tread feeding template and the zero-belt feeding template to move in the opposite direction to the initial position.

[0017] By applying the technical solution of this invention, a tread supply template and a zero-belt supply template are provided, and both the tread supply template and the zero-belt supply template are driven and connected to a tread and zero-belt drive mechanism. This allows the tread supply template and the zero-belt supply template to share a single drive mechanism, thereby reducing the overall structural complexity of the device and lowering costs. Simultaneously, sharing a single drive mechanism still ensures the normal bonding of the belt layer, tread, and other rubber materials. During bonding, the tread and zero-belt drive mechanism jointly drives both the tread supply template and the zero-belt supply template to the required position. Then, the tread supply template and the zero-belt supply template can operate independently as needed to achieve bonding, thus realizing the bonding of the tread and the zero-belt. Furthermore, the auxiliary machine-side feeding device in this embodiment defines all feeding types for the auxiliary machine-side feeding method of the all-steel forming machine, realizing automatic belt layer and automatic tread bonding, and meeting the logical and spatial layout requirements for zero-belt bonding. It can also meet the bonding requirements of various rubber materials and the production needs of various tire specifications. Using a van as the tread tooling, it automatically bonds the tread, automatically bonds the 1-4# belt layers, and incorporates the 0# belt layer process. The bonding angle above the belt layer is optimized to allow for simultaneous bonding of the zero-belt and tread. By combining the mechanical structure and control sequence of each part, the auxiliary machine feeding system achieves automation and diversification of detection, transportation, and bonding functions. The layout, structure, and feeding sequence of each feeding rack are clearly defined. Each module has independent functions and a clear division of labor, making subsequent modifications and uses clear. Attached Figure Description

[0024] 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.

[0025] 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.

[0026] 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.

[0027] To address the problems of complex structure and high cost of auxiliary machine side feeding devices in the prior art, the present invention provides an auxiliary machine side feeding device and auxiliary machine side feeding method.

[0028] like Figures 1 to 3 The auxiliary machine side feeding device shown includes: a frame, a tread feeding template 10, a zero-belt feeding template 20, and a tread / zero-belt drive mechanism 30. The tread feeding template 10 is movably connected to the frame; the zero-belt feeding template 20 is movably connected to the frame and moves synchronously with the tread feeding template 10 in at least one direction; the tread / zero-belt drive mechanism 30 is driven connected to both the tread feeding template 10 and the zero-belt feeding template 20, and is capable of driving both the tread feeding template 10 and the zero-belt feeding template 20 to move synchronously in at least one direction.

[0029] This embodiment features a tread supply template 10 and a tire belt supply template 20, both of which are connected to a tread / tread belt drive mechanism 30. This allows the tread supply template 10 and the tire belt supply template 20 to share a single drive mechanism, reducing the overall structural complexity and cost of the device. While sharing a single drive mechanism, the proper bonding of the belt layer and tread materials is still ensured. During bonding, the tread / tread belt drive mechanism 30 moves both the tread supply template 10 and the tire belt supply template 20 to the required position. Then, the tread supply template 10 and the tire belt supply template 20 can operate independently as needed to achieve bonding between the tread and the tire belt. Furthermore, the auxiliary machine-side feeding device in this embodiment defines all feeding types for the auxiliary machine-side feeding method of the all-steel forming machine, realizing automatic belt layer and automatic tread bonding, and meeting the logical and spatial layout requirements for zero-belt bonding. It can also meet the bonding requirements of various rubber materials and the production needs of various tire specifications. Using a van as the tread tool 70, it automatically bonds the tread, automatically bonds the 1-4# belt layers, and uses the 0# belt layer process. The bonding angle above the belt layer is optimized to allow for simultaneous bonding of the zero-belt and tread. Combining the mechanical structure and control sequence of each part, the auxiliary machine feeding system achieves automation and diversification of detection, transportation, and bonding functions. The layout, structure, and feeding sequence of each feeding rack are clearly defined. Each module has independent functions and a clear division of labor, making subsequent modifications and uses clear.

[0030] like Figure 1 and Figure 2 As shown, in this embodiment, both the tread feeding template 10 and the zero-belt feeding template 20 can be raised and lowered relative to the frame, and the raising and lowering is vertical. The tread and zero-belt driving mechanism 30 can drive the tread feeding template 10 and the zero-belt feeding template 20 to rise and fall synchronously. The synchronously raised and lowered tread feeding template 10 and zero-belt feeding template 20 have three vertical position states: the initial position, the zero-belt bonding position for bonding the zero-belt, and the tread bonding position for bonding the tread. The zero-belt bonding position and the tread bonding position can be the same or different positions depending on the situation. The tread feeding template 10 and the zero-belt feeding template 20 can switch between the initial position, the zero-belt bonding position, and the tread bonding position by means of the tread and zero-belt driving mechanism 30. After the position is switched, the tread feeding template 10 and the zero-belt feeding template 20 can move on their own according to the bonding needs, such as moving laterally or rotating, to bond the tread or zero-belt to the belt drum 50. Of course, in addition to the vertical lifting setting, the tilting lifting method or other movement methods can also be used as needed, as long as the positions of the tread material feeding template 10 and the zero-belt material feeding template 20 can be adjusted to achieve the bonding of the rubber material or to avoid the movement of other mechanisms.

[0031] In this embodiment, the tread feeding template 10 and the zero-belt feeding template 20 are vertically higher in their initial positions than in their zero-belt bonding positions and tread bonding positions. Furthermore, the tread feeding template 10 and the zero-belt feeding template 20 are vertically higher in their zero-belt bonding positions than in their tread bonding positions. Thus, the initial position, zero-belt bonding position, and tread bonding position are sequentially arranged from top to bottom. This arrangement ensures that the auxiliary machine-side feeding device conforms to the bonding logic and sequence in the subsequent bonding process. Specifically, when bonding is not required, both the tread feeding template 10 and the zero-belt feeding template 20 are in their initial positions, allowing them to avoid the normal operation of other mechanisms. When bonding is required, they descend to the necessary positions to perform the bonding action. Simultaneously, the tread bonding template 22 and the zero-belt bonding template 22 utilize the same drive mechanism, reducing the use of one additional drive mechanism and lowering the cost of the auxiliary machine-side feeding device.

[0032] In this embodiment, the tread zero-belt drive mechanism 30 can be driven by a servo electric cylinder. When the tread feeding template 10 and the zero-belt bonding template 22 are raised and lowered to switch between the initial position, the zero-belt bonding position, and the tread bonding position, the servo electric cylinder is used as the drive component. This makes the vertical position control of the tread zero-belt drive mechanism 30 more precise, and the vertical position switching of the tread feeding template 10 and the zero-belt feeding template 20 more accurate and controllable.

[0033] In this embodiment, the tread feeding template 10 is located above the zero-track feeding template 20. This arrangement of the tread feeding template 10 and the zero-track feeding template 20 is logical and spatially meets the requirements for zero-track bonding. The tread feeding template 10 and the zero-track feeding template 20 have two motion states: stationary and relative to the frame, both moving upwards and downwards. During these two motion states, there is always a height difference between the tread feeding device and the zero-track feeding template that remains unchanged regardless of the motion state; that is, they remain relatively stationary during the lifting and lowering process.

[0034] In this embodiment, the auxiliary machine side feeding device also includes a belt layer feeding template 40. The function of the belt layer feeding template 40 is to bond the 1-4# belt layers. The belt layer feeding template 40 is located below both the tread feeding template 10 and the zero belt feeding template 20, so that the bonding action of the 1-4# belt layers can be performed normally. This is also one of the reasons why the initial position is set at a relatively high position, that is, when the tread feeding template 10 and the zero belt feeding template 20 are in the initial position, there is enough space between them and the belt layer feeding template 40, so that the action of the belt layer feeding template 40 will not be affected.

[0035] Preferably, by combining the aforementioned arrangement of the tread feeding template 10 above the zero-belt feeding template 20, the tread feeding template 10, the zero-belt feeding template 20, and the belt layer feeding template 40 form a structure arranged sequentially from top to bottom. This makes the overall spatial layout of the auxiliary machine side feeding device reasonable, which can meet the bonding requirements of the belt layer, zero belt, and tread, realize all types of material feeding on the auxiliary machine side, and enable the production of tires of various specifications and processes without changing the machine, thus having broad economic value.

[0036] In this embodiment, the tread feeding template 10 and the zero-track feeding template 20 can have the same structure or different structures. This embodiment uses the example of two templates having the same structure for illustration. Figure 3 As shown, taking the zero-belt feeding template 20 as an example, the zero-belt feeding template 20 includes: a pre-feeding template 21, a bonding template 22, and a bonding drive component 23. The feeding template 21 is adjustable relative to the frame and is connected to the tread belt drive mechanism 30, which drives the feeding template 21 to lift and lower. The bonding template 22 is movably connected to the feeding template 21 and is located at the end of the feeding template 21 near the belt drum 50. The bonding template 22 can be moved laterally relative to the feeding template 21. When bonding is required, the tread belt drive mechanism 30 drives the feeding template 21 to descend, and the bonding template 22 descends to the same position. The bonding template 22 then moves laterally closer to the belt drum 50. The bonding template 22 can be rotated at a certain angle to adjust the bonding angle, and then the bonding template can be bonded to the belt drum 50 to achieve bonding. The bonding drive 23 can be a component such as an electric cylinder. The bonding drive 23 is connected to the bonding template 22 and plays the role of driving the bonding template 22 to move laterally, thereby driving the bonding template 22 to move closer to or further away from the belt layer drum 50 to achieve zero-belt bonding.

[0037] In this embodiment, the zero-belt feeding template 20 also includes a post-feeding template. The post-feeding template and the pre-feeding template 21 can be connected together or not. When not connected, the post-feeding template can be fixed relative to the frame, and the lifting action only occurs at the pre-feeding template 21. Along the material conveying direction, the post-feeding template is farther away from the belt drum 50 than the pre-feeding template 21. That is, the post-feeding template and the bonding template 22 are located at opposite ends of the pre-feeding template 21. The post-feeding template mainly serves to convey the zero belt, and can also perform functions such as centering, heating, and length measurement as needed (currently, heating and length measurement functions are not provided). The auxiliary feeding device also includes a floating tensioning mechanism 60. The feeding template has a floating tensioning mechanism 60. The floating tensioning mechanism 60 can be a tensioning wheel or other components. The material is conveyed around the floating tensioning mechanism 60. The floating tensioning mechanism 60 can be moved so that when conveying the rubber material or when the template 21 before feeding is raised or lowered, the floating tensioning mechanism 60 can be automatically or manually adjusted to achieve the effect of controlling the tension of the material and ensuring smooth conveying of the zero belt.

[0038] In this embodiment, each feeding template of the auxiliary machine side feeding device can be used with the tread tooling 70 to provide the tread, etc.

[0039] In this embodiment, the auxiliary machine-side feeding device adopts a reasonable spatial layout, specifically as follows: the belt layer drum 50 is located directly in front of the entire auxiliary machine-side feeding device. The belt layer drum 50 has a side surface that is distinct from the annular bonding surface, and this side surface is parallel to the conveying direction of the tread feeding template 10, the zero-belt feeding template 20, and the belt layer feeding template 40. The tread feeding template 10, the zero-belt feeding template 20, and the belt layer feeding template 40 are arranged sequentially from top to bottom, wherein the tread feeding template 10 and the zero-belt feeding template 20 are synchronously raised and lowered, and are jointly driven by the tread-zero-belt drive mechanism 30. The tread feeding template 10, the zero-belt feeding template 20, and the belt layer feeding template 40 all have a pre-feeding template 21 and a post-feeding template. The pre-feeding template 21 of all three is responsible for bonding with the belt layer, while the post-feeding templates are responsible for conveying the tread, zero-belt, and belt layer to the bonding position, respectively. Based on this requirement, the pre-feeding template 21 of the tread feeding template 10, zero-belt feeding template 20, and belt layer bonding template 22 of the auxiliary machine side feeding device is closer to the belt layer drum 50 than the post-feeding template. The zero-belt feeding template 20 also has a drive cylinder as a drive component to extend the zero-belt feeding template 20.

[0040] In this embodiment, the zero-belt feeding template 20 and the tread feeding template 10 can be used not only for the automatic lower bonding belt layer feeding rack but also for the automatic upper bonding belt layer feeding rack and the manual belt layer feeding rack. The zero-belt feeding template 20 and the belt layer feeding template 40 can be used not only for the tread feeding rack of the van tooling but also for the area above the rear-mounted rolling tread feeding rack and the area above the rear-mounted louvered tread feeding rack.

[0041] This embodiment also provides an auxiliary machine-side material supply method, employing the aforementioned auxiliary machine-side material supply device. The auxiliary machine-side material supply method includes: selecting the rubber compound bonding sequence according to the tire compound formula, and bonding the rubber compounds sequentially according to the bonding sequence; when bonding the tread or tire belt is required, the tread / tread belt drive mechanism 30 drives the tread material supply template 10 and the tire belt supply template 20, causing them to move synchronously to the tread bonding position or the tire belt bonding position, and then the tread material supply template 10 or the tire belt supply template 20 performs tread or tire belt bonding. In this way, the auxiliary machine-side material supply method, in conjunction with the aforementioned auxiliary machine-side material supply device, achieves automatic belt layer and automatic tread bonding, satisfying the logical and spatial layout requirements for tire belt bonding. Simultaneously, the overall structure and usage are relatively simple, easy to operate, and conducive to cost reduction.

[0042] In this embodiment, the auxiliary machine side feeding method further includes: when the tread zero-belt drive mechanism 30 drives the tread feeding template 10 and the zero-belt feeding template 20 to move synchronously, the tread zero-belt drive mechanism 30 drives the tread feeding template 10 and the zero-belt feeding template 20 to move up and down synchronously, so that the tread feeding template 10 and the zero-belt feeding template 20 move to a predetermined height position, and then the tread feeding template 10 or the zero-belt feeding template 20 actuates to perform adhesive bonding.

[0043] In this embodiment, the auxiliary machine side feeding method further includes: when it is necessary to bond the belt layer, the belt layer feeding template 40 switches to the bonding state to bond the belt layer; when bonding one of the tread, the zero belt, and the belt layer, the bonding template 22 corresponding to the other two of the tread, the zero belt, and the belt layer performs material preparation work including at least one of cutting, centering, length measurement and heating.

[0044] In this embodiment, the auxiliary machine side feeding method further includes: when the tread feeding template 10 or the zero-belt feeding template 20 is in motion to apply the adhesive, the floating tensioning mechanism 60 is activated to prevent the adhesive from being stretched, and the bonding drive 23 drives the bonding template 22 to move laterally and approach the belt drum 50 to apply the adhesive; after the bonding is completed, the bonding drive 23 drives the bonding template 22 to move laterally in the opposite direction and away from the belt drum 50, and at the same time the floating tensioning mechanism 60 is activated, and the tread zero-belt drive mechanism 30 drives the tread feeding template 10 and the zero-belt feeding template 20 to move in the opposite direction to the initial position.

[0045] The following example, using the determined tire bonding sequence of #1, #2, #3, #4 belt layers + zero belt + tread, illustrates the specific operation process of the auxiliary machine-side material feeding method described above:

[0046] 1. The bonding template 22 on the belt layer feeding template 40, which is equipped with automatic cutting and automatic bonding, is positioned in the bonding state, and the adhesive materials of each belt layer are bonded together.

[0047] 2. After the tread material preparation is completed, the tread zero-belt drive mechanism 30 drives the tread bonding template 22 and the zero-belt bonding template 22 to descend above the belt drum 50 to await bonding. At this time, the tread feeding template 10 can perform centering, heating, and one-time length measurement. The bonding drive component 23 of the zero-belt feeding template 20 is activated, driving its bonding template 22 to extend above the belt drum 50 to await bonding. This process does not have a clear order with the process in step 1; it can be performed sequentially or simultaneously.

[0048] 3. After the belt layer bonding is completed, the tread belt drive mechanism 30 drives the pre-feeding template 21 of the belt feeding template 20 to the bonding position of the belt, bonding the belt material. During this process, when the belt feeding template 20 descends to the waiting bonding position, the bonding drive component 23 drives the bonding template 22 to extend, and the floating tensioning mechanism 60 on the post-feeding template activates to prevent belt stretching. When the belt feeding template 20 continues to descend to bond the tread material, the bonding drive component 23 drives the bonding template 22 to retract, and the floating tensioning mechanism 60 continues to activate to reduce belt stretching. During subsequent lifting and lowering movements of the belt feeding template 20, the floating tensioning mechanism 60 continues to activate to prevent belt stretching.

[0049] 4. After the zero-belt rubber material is bonded, the bonding template 22 on the zero-belt feeding template 20 returns, and the tire tread zero-belt drive mechanism 30 drives the tire tread feeding template 10 and the zero-belt feeding template 20 to continue to descend to the bonding position of the tire tread and bond the tire tread rubber material.

[0050] 5. After the tread rubber compound is bonded, the tread zero-belt drive mechanism 30 drives the tread material supply template 10 and the zero-belt material supply template 20 back to their initial positions, waiting for the next bonding.

[0051] When the determined bonding sequence of the adhesive materials changes, the order of the above process can be adjusted accordingly. If some adhesive materials do not need to be bonded, the bonding process of the corresponding adhesive materials can be cancelled.

[0052] It should be noted that "multiple" in the above embodiments refers to at least two.

[0053] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0054] 1. This technology solves the problems of complex structure and high cost of auxiliary machine-side feeding devices in existing technologies;

[0055] 2. The tread feeding template and the zero-belt feeding template share a common drive mechanism, which can reduce the overall structural complexity of the device and reduce costs;

[0056] 3. For the auxiliary machine side material supply method of the all-steel forming machine, all material supply types on the auxiliary machine side are defined to realize automatic belt layer and automatic tread bonding, and meet the reasonable layout of zero belt bonding requirements in logic and space.

[0057] 4. It can meet the requirements of various rubber compound bonding and the production needs of various tire specifications. It uses a van as the tread tool, automatically bonding the tread and the 1-4# belt layers, and is equipped with the 0# belt layer process. The bonding angle is optimized above the belt layer to meet the simultaneous bonding of the zero belt and the tread.

[0058] 5. By combining the mechanical structure and control sequence of each part, the auxiliary machine feeding system can achieve automation and diversification of detection, transportation, and bonding functions;

[0059] 6. The layout, structure, and feeding sequence of each feeding rack, as well as the independent function and clear division of labor of each module, make subsequent modifications and use clear.
