Description

Technical Field

[0001] The present invention relates to the technical field of tire production, and in particular to an automatic production line and method for solid tires. Background Art

[0002] The production process of solid tires is to wrap different thin rubber sheets around rubber sleeves to finally obtain tire blanks with weight and size that meet the process requirements. Common solid tires first wrap the base rubber around the rubber sleeve, then wrap the highly elastic intermediate rubber around the base rubber, and finally wrap the wear-resistant tread rubber around the intermediate rubber. The weight ratio of the base rubber, intermediate rubber and tread rubber is generally 3:2:5, and the output of these rubber sheets is mainly completed by an open mixing mill. In the related technology, the production of solid tires mostly adopts the following two methods:

[0003] 1. One open mixing mill outputs three types of films, and the rest of the processes are all manually operated. This method not only requires frequent replacement of the rubber material, but also has high labor intensity and low production efficiency;

[0004] 2. Each type of rubber compound is equipped with an open mixing mill, but the production process is still mainly completed manually, including loading and unloading, transportation, tapping, size measurement, etc. of tire blanks, which has high labor intensity and low production efficiency and product quality.

[0047] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0048] like Figure 1 and Figure 2As shown, an automatic production line for solid tires according to an embodiment of the present invention comprises a base rubber winding system 1, an intermediate rubber winding system 2 and a tread rubber winding system 3 which are connected in sequence, and there are two tread rubber winding systems 3 which are connected with the intermediate rubber winding system 2 respectively; each of the base rubber winding system 1, the intermediate rubber winding system 2 and the tread rubber winding system 3 comprises a connected open mixing mill 11 and an execution component 12, the open mixing mill 11 is used for calendering the rubber into a film to output it so as to wind the film around the tire blank, and the execution component 12 is suitable for being connected with the tire blank and being able to move the tire blank; the execution component 12 of the base rubber winding system 1 and the execution component 12 of the intermediate rubber winding system 2 are connected through a first storage table 4, and the first storage table 4 is used for temporarily storing the primary tire blank wound with the base rubber film, and the execution component 12 of the intermediate rubber winding system 2 and the execution component 12 of the tread rubber winding system 3 are connected through a second storage table 5, and the second storage table 5 is used for temporarily storing the intermediate tire blank wound with both the base rubber film and the intermediate rubber film.

[0049] It can be understood that the automatic production line for solid tires according to the embodiment of the present invention is coordinated by a base rubber winding system 1, an intermediate rubber winding system 2 and two tread rubber winding systems 3, forming a machine configuration method that is basically consistent with the weight ratio of various types of films wound on the solid tire (that is, the weight ratio of base rubber: intermediate rubber: tread rubber is 3:2:5), so as to facilitate the winding process of the base rubber, intermediate rubber and tread rubber on the rubber sleeve in sequence, reduce the waiting time in the production process of each process, and improve the utilization rate and production efficiency of the equipment. Among them, two sets of open mixing mills 11 are configured for the sheet winding of the tread rubber, which can ensure that the production time of each process is basically the same, and the auxiliary design of the execution component 12, the first storage table 4 and the second storage table 5 enables the tire blanks between adjacent processes to be automatically transferred and temporarily stored, realizing the series connection of the automatic winding production process of various types of films. Therefore, compared with the relevant technology, the present invention can realize the automation of the solid tire production process, reduce labor intensity, and improve production efficiency and product quality.

[0050] Specifically, the open mill 11 may be provided with a forming roller to calender the rubber material into a film for output. Its specific structure and working principle may adopt the existing technology in the field and will not be expanded here. The execution component 12 can automatically grab the tire blank. For example, a forming drum may be installed on the execution component 12. The forming drum has an expansion and contraction function. After contraction, it can extend into the inner hole of the tire blank, and then expand to clamp the tire blank, so as to realize the automatic grasping of the tire blank by the execution component 12, that is, the automatic connection between the execution component 12 and the tire blank, thereby improving production efficiency. The primary tire blank can be placed upright on the first storage platform 4, and its center of circle coincides with the center of the opening of the first storage platform 4. Similarly, the intermediate tire blank can also be placed upright on the second storage platform 5, and its center of circle coincides with the center of the opening of the second storage platform 5, so that the forming drum on the execution component 12 is connected to the corresponding tire blank.

[0051] like Figure 1and Figure 2 As shown, in some embodiments, the actuator 12 of the base rubber winding system 1 is also suitable for being connected to the rubber sleeve and can move the rubber sleeve to the mixing mill 11 of the base rubber winding system 1 to wind the base rubber film, thereby realizing automatic transfer and winding of the rubber sleeve and further improving the automation performance of the production line.

[0052] like Figure 1 and Figure 2 As shown, in some embodiments, the actuator 12 of at least one of the intermediate rubber winding system 2 and the tread rubber winding system 3 can also move the tire blank to the corresponding mixing mill 11 to wind the film, thereby realizing automatic transfer and winding of the tire blank, and further optimizing the automation performance of the production line.

[0053] It can be understood that the actuator 12 of the intermediate rubber winding system 2 is capable of moving the tire blank to its open mill 11 to wind the film; or, the actuator 12 of the tread rubber winding system 3 is capable of moving the tire blank to its open mill 11 to wind the film; or, the actuator 12 of each of the intermediate rubber winding system 2 and the tread rubber winding system 3 is capable of moving the tire blank to the corresponding open mill 11 to wind the film.

[0054] It should be noted that in order to further ensure the automated production of solid tires on the production line, the tire blank (or rubber sleeve) on the execution component 12 can also be designed to cooperate with the mixing mill 11 to automatically transfer the film output by the mixing mill 11 and wrap it around the tire blank (or rubber sleeve).

[0055] like Figure 1 and Figure 2 As shown, in some embodiments, each of the base rubber winding system 1, the intermediate rubber winding system 2 and the tread rubber winding system 3 also includes an extruder unit 13, and the extruder unit 13 is used to plasticize the rubber material. The extruder unit 13 is connected to the mixing mill 11 through a conveyor line to continuously supply rubber to the mixing mill 11, so that the corresponding rubber material can be directly supplied to the mixing mill 11 after being heated and plasticized by the extruder unit 13, thereby ensuring the continuous output of the rubber sheet and providing a prerequisite for the continuous and automated production of solid tires.

[0056] It should be noted that in the related art, the plasticizing of solid tire rubber is usually completed by an open mixing mill 11, among which the intermediate rubber and tread rubber have been generally plasticized by an extruder due to their low hardness; and the base rubber is fiber rubber with high hardness, which is usually plasticized by a kneading mill or a rubber breaker and then supplied to the open mixing mill 11, which is an intermittent production method. Therefore, the extruder unit 13 in the base rubber winding system 1 of the present invention can meet the plasticizing requirements of the fiber rubber by adjusting at least one of the power, strength and torque of the screw (for example, using an extruder with high power, high torque, low speed and high heat exchange efficiency) to achieve continuous supply of fiber rubber.

[0057] like Figure 1 and Figure 2 As shown, in some embodiments, an active area 14 is jointly defined between the open mixing mill 11 of the base rubber winding system 1, the open mixing mill 11 of the intermediate rubber winding system 2, and the open mixing mill 11 of each of the two tread rubber winding systems 3, and the actuator 12 of the base rubber winding system 1, the intermediate rubber winding system 2, and each of the two tread rubber winding systems 3 can be pivotally mounted in the active area 14 and arranged adjacent to the corresponding open mixing mill 11.

[0058] A transition storage platform 6 is provided between at least one of the two tread rubber winding systems 3 and the second storage platform 5 . The second storage platform 5 and the transition storage platform 6 are connected via a first transfer component 7 . The first transfer component 7 can transfer the intermediate tire blank to the transition storage platform 6 .

[0059] It can be understood that the above-mentioned structural arrangement makes the production line compact and reduces space occupation.

[0060] For instance, taking the figure as an example, the open mixer 11 of the base rubber winding system 1 and the open mixer 11 of the outer tread rubber winding system 3 can be arranged in the front-to-back direction, and the open mixer 11 of the middle rubber winding system 2 and the open mixer 11 of the inner tread rubber winding system 3 can be arranged in the left-to-right direction, wherein the open mixer 11 of the base rubber winding system 1 is located on the far left, the open mixer 11 of the middle rubber winding system 2 and the open mixer 11 of the inner tread rubber winding system 3 are arranged adjacent to each other in the left-to-right direction and are both located in the middle, and the open mixer 11 of the outer tread rubber winding system 3 is located on the far right, thereby defining an inverted U-shaped activity area 14 between the four.

[0061] like Figure 1 and Figure 2 As shown, in some embodiments, the automatic production line for solid tires also includes a weighing station 8, and the first transfer component 7 is connected to the weighing station 8 and can transfer the finished tires wrapped with the base rubber film, the intermediate rubber film and the tread rubber film to the weighing station 8 for weighing, so as to judge whether the weight of the finished tire is qualified.

[0062] like Figure 1 and Figure 2 As shown, in some embodiments, the automatic production line for solid tires also includes a third storage table 81, and the execution component 12 of each of the two tread rubber winding systems 3 is connected to the third storage table 81 and can temporarily store the finished tires on the third storage table 81. The third storage table 81 is connected to the weighing station 8 through the first transfer component 7, so that the first transfer component 7 can automatically transfer the finished tires on the third storage table 81 to the weighing station 8 for weighing, thereby further ensuring the production continuity of the entire production line.

[0063] like Figure 1 and Figure 2As shown, in some embodiments, the solid tire automatic production line also includes a manual processing station 82, which is connected to the weighing station 8 through a second transfer component 83. The manual processing station 82 is used to cut off the overweight rubber or fill the insufficient rubber for the finished tires that do not meet the weight requirements. The second transfer component 83 can enable the finished tires to flow between the manual processing station 82 and the weighing station 8 to achieve the processing of unqualified finished tires, further improving the performance of the production line and ensuring the quality of the finished tires.

[0064] It should be noted that in the control system of the production line, the length of the film winding during the production process can be automatically adjusted according to the accumulation of production data and weight feedback, thereby improving the qualified rate of the finished tire weight and reducing the intensity of manual work.

[0065] Furthermore, the first storage table 4 , the second storage table 5 , the transition storage table 6 , the first transfer component 7 , the weighing station 8 , the third storage table 81 , the manual processing station 82 and the second transfer component 83 are all located in the activity area 14 .

[0066] Furthermore, the execution component 12 of each of the base rubber winding system 1, the intermediate rubber winding system 2 and the two tread rubber winding systems 3 can be a transfer robot, and each of the first transfer component 7 and the second transfer component 83 can be one of a transfer robot and a conveyor line.

[0067] Taking the figure as an example, when the actuator 12 and the first transfer assembly 7 are both transfer robots, and the second transfer assembly 83 is a conveyor line (such as a conveyor roller), the first storage table 4 can be located between the actuator 12 of the base rubber winding system 1 and the actuator 12 of the intermediate rubber winding system 2, there can be two second storage tables 5 arranged in the front-to-back direction, and the second storage tables 5 can be located between the actuator 12 of the intermediate rubber winding system 2 and the actuator 12 of the inner tread rubber winding system 3, there can be one transition storage table 6 and it is located between the actuator 12 of the outer tread rubber winding system 3 and the first transfer assembly 7, the third storage table 81 is located between the actuators 12 of the two tread rubber winding systems 3, and the weighing station 8 is located on the front side of the transition storage table 6.

[0068] Among them, the execution component 12 of the base rubber winding system 1, the first storage platform 4, the execution component 12 of the intermediate rubber winding system 2, the second storage platform 5 (rear side), the execution component 12 of the inner tread rubber winding system 3 and the third storage platform 81 are connected in sequence and constitute a production line for the tire blank; or, the execution component 12 of the base rubber winding system 1, the first storage platform 4, the execution component 12 of the intermediate rubber winding system 2, the second storage platform 5 (front side), the first transfer component 7, the transition storage platform 6, the execution component 12 of the outer tread rubber winding system 3 and the third storage platform 81 are connected in sequence and constitute another production line for the tire blank. The third storage platform 81, the first transfer component 7, the weighing station 8, the second transfer component 83 and the manual processing station 82 are connected in sequence to realize the weighing of the finished tires and the processing of unqualified finished tires.

[0069] In addition, when the execution component 12 is a transfer robot, and the first transfer component 7 and the second transfer component 83 are both conveyor lines (such as conveyor rollers), the difference from the above is that there is one second storage platform 5 and two transition storage platforms 6. The second storage platform 5 and the left transition storage platform 6 are arranged adjacently between the execution component 12 of the middle rubber winding system 2 and the execution component 12 of the inner tread rubber winding system 3, and the right transition storage platform 6 is located between the execution components 12 of the two tread rubber winding systems 3. The right transition storage platform 6, the third storage platform 81 and the weighing station 8 are arranged in sequence from back to front, and the second storage platform 5, the two transition storage platforms 6, the third storage platform 81 and the weighing station 8 are connected in sequence through the first transfer component 7. The second storage platform 5 and the two transition storage platforms 6 can also be raised and lowered to lift the tire blank, so that the molding drum on the execution component 12 can be inserted into the inner hole of the tire blank to achieve stable and reliable clamping.

[0070] like Figure 1 and Figure 2 As shown, in some embodiments, the solid tire automatic production line further includes a tire unloading trolley 84, and the weighing station 8 is connected to the tire unloading trolley 84 through the first transfer assembly 7, or the weighing station 8 is connected to the tire unloading trolley 84 through the tire unloading truss 85, so that any one of the first transfer assembly 7 and the tire unloading truss 85 can transfer the finished tires with qualified weight to the tire unloading trolley 84, so as to realize the automatic unloading operation of the finished tires, and further improve the automation performance of the production line. The tire unloading trolley 84 is not limited to an AGV trolley.

[0071] Specifically, the tire unloading cart 84 can extend along its travel direction so that the tire unloading cart 84 (such as an AGV cart) moves forward one workstation each time it loads a tire blank, thereby enabling the tire unloading cart 84 to load multiple finished tires, and the tire unloading cart 84 can be automatically replaced when full.

[0072] like Figure 3As shown, in some embodiments, the solid tire automatic production line further includes a lifting pallet 9, which can be lifted and lowered in the height direction and is used to carry the rubber sleeve, and the actuator 12 of the base rubber winding system 1 is connected to the lifting pallet 9 and can grab the rubber sleeve on the lifting pallet 9, so that the actuator 12 of the base rubber winding system 1 can clamp the rubber sleeve to ensure the operation continuity of the production line. The rubber sleeve can be placed upright on the lifting pallet 9.

[0073] like Figure 3 As shown, in some embodiments, the solid tire automatic production line further includes a clamping plate 91, which is connected to the lifting support plate 9, and the clamping plate 91 has at least two clamping cavities that jointly define a clamping cavity for accommodating the rubber sleeve, so as to limit the rubber sleeve on the lifting support plate 9 (that is, the clamping plate 91 can be pressed against the outer peripheral wall of the rubber sleeve), ensuring that the rubber sleeve is stably and reliably placed on the lifting support plate 9. Among them, the lifting support plate 9 and the clamping plate 91 together constitute a rubber sleeve clamping platform.

[0074] like Figure 3 As shown, in some embodiments, the automatic production line for solid tires further includes a rubber sleeve trolley 92 and a rubber sleeve picking mechanism 93. The rubber sleeve trolley 92 is provided with a limit groove, which is suitable for loading the rubber sleeve. The lifting support plate 9 is connected to the limit groove through the rubber sleeve picking mechanism 93. The rubber sleeve picking mechanism 93 is provided with a picking fixture, which is suitable for grabbing the rubber sleeve so that the rubber sleeve can be transferred to the lifting support plate 9, so as to automatically supply the rubber sleeve to the lifting support plate 9. In combination with the structure of the production line described above, the automatic production process of solid tires is opened up, which greatly reduces the labor intensity of the solid tire production process and improves production efficiency and product quality. Among them, the rubber sleeve clamping table, the rubber sleeve trolley 92 and the rubber sleeve picking mechanism 93 together constitute a rubber sleeve picking device.

[0075] Specifically, the rubber sleeve picking mechanism 93 may not be limited to a truss (such as a three-axis truss), and a picking fixture is installed on the truss, which can be driven by the truss to reach each rubber sleeve position and the rubber sleeve clamping table position. When the picking fixture puts the rubber sleeve on the rubber sleeve clamping table and exits, the clamping plate 91 of the rubber sleeve clamping table holds the rubber sleeve from the outside, and the lifting support plate 9 descends, thereby allowing the forming drum to extend into the inner hole of the rubber sleeve. In addition, after the rubber sleeve trolley 92 is sent to the workstation, it must be positioned and locked to ensure the accuracy of the rubber sleeve position on the rubber sleeve trolley 92, and the transportation of the rubber sleeve trolley 92 can be completed manually or by factory logistics.

[0076] Further, there are multiple limiting grooves arranged in an array on the rubber sleeve trolley 92. Among them, the specific specifications of the limiting grooves can be designed according to different rubber sleeve sizes to ensure that the position of the rubber sleeve is accurate each time it is placed on the rubber sleeve trolley 92.

[0077] Furthermore, there are two rubber sleeve trolleys 92 which supply rubber sleeves to the rubber sleeve picking mechanism 93 in turn, so that the other rubber sleeve trolley 92 can be sent to the corresponding workstation before the rubber sleeves on one rubber sleeve trolley 92 are used up, thereby ensuring the continuity of the rubber sleeve supply.

[0079] It should be noted that, for the return to zero of the primary tire embryo and the intermediate tire embryo, for example, the length of the film can be measured with the help of an encoder installed on the forming roller of the open mill 11, and the angle of rotation of the forming roller can be calculated, and the position of the tail of the film wound on the primary tire embryo or the intermediate tire embryo can be obtained through visual detection or contact switch detection, so as to control the rotation angle of the first storage table 4 or the second storage table 5 and realize the return to zero of the primary tire embryo or the intermediate tire embryo. The realization of this part of the function can adopt the existing technology in the field and is not specifically limited to this.
