Description

Technical Field

[0001] The present invention relates to the technical field of tire processing, and in particular to a roller changing device and an automatic roller changing system. Background Art

[0002] As OTR tires increasingly utilize tubeless technology, the innerliners of OTR tires are increasingly approaching the strip extrusion technology of all-steel innerliners. This has led to the use of larger innerliners in OTR tires. However, during the production process, these larger innerliners require the use of calenders with larger, interchangeable roller sleeves. Because the required roller sleeve dimensions and the resulting shapes remain the same across all tires, the roller sleeves in the calender must be replaced as needed to accommodate varying processing requirements.

[0003] Currently, roller sleeve replacement is mostly done manually. Due to the heavy weight of these calendered roller sleeves (typically approaching 1000 kg), manual operation is extremely difficult and dangerous. Transporting the roller sleeves using ground trolleys also presents limitations such as limited movement and a high reliance on ground tracks, resulting in low installation efficiency.

DETAILED DESCRIPTION

[0042] The 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.

[0043] The following combination Figures 1-17 A roll changing device and an automatic roll changing system according to an embodiment of the present invention are described.

[0044] The embodiment of the present invention provides a roller changing device, such as Figures 1-14 The roller changing device includes a carrier mechanism 1, a rotating mechanism 3 and a translation mechanism 4, as shown in FIG. Figure 1 As shown, the carrier mechanism 1 is used to grab or release the roller sleeve 2, and part of the carrier mechanism 1 can be inserted into the roller sleeve 2 and connected to the roller sleeve 2; the rotating mechanism 3 is connected to the carrier mechanism 1 and can drive the carrier mechanism 1 to rotate in the horizontal plane to change the direction of the carrier mechanism 1; the translation mechanism 4 is connected to the rotating mechanism 3, and when the translation mechanism 4 is started, the carrier mechanism 1 can move between the storage position and the installation position of the roller sleeve 2.

[0045] The carrier mechanism 1, rotating mechanism 3, and translation mechanism 4 in this roller-changing device work together to adjust the orientation and movement path of the roller sleeve 2 through the rotating mechanism 3 and translation mechanism 4, while the carrier mechanism 1 is used to grasp or release the roller sleeve 2. This effectively transfers the roller sleeve 2 between its storage and installation positions. Furthermore, the device can cooperate with a calender 100 located at its installation location to enable the roller sleeve 2 to be detached from, grasped, transported, and repositioned relative to the calender 100, achieving efficient replacement of the roller sleeve 2. During this process, the device allows for rapid replacement of the roller sleeve 2, reduces manual intervention, improves safety and efficiency, and mitigates the risk of personal injury associated with manual replacement of the roller sleeve 2.

[0046] It should be noted that when the roller sleeve 2 is installed on the carrier mechanism 1 , the orientation of the roller sleeve 2 on the carrier mechanism 1 will change synchronously with the change in the orientation of the carrier mechanism 1 .

[0047] The above-mentioned translation mechanism 4 is located between the storage position and the installation position. Under the action of the translation mechanism 4, the carrier mechanism 1 can drive the roller sleeve 2 to move between the two. Figure 1 and Figure 2 As shown, at this time, the number of the above-mentioned storage positions is two and they are located on both sides of a certain moving path of the translation mechanism 4, and at this time, the installation position is located on one side of another moving path of the translation mechanism 4.

[0048] The following is an explanation of the roll changing process of the roll changing device:

[0049] When a roller sleeve 2 installed on the calender 100 needs to be removed and stored, the carrier mechanism 1 can be driven by the translation mechanism 4 and the rotation mechanism 3 to move to a position that matches the roller sleeve 2 of the calender 100 and match the roller sleeve 2 to be removed, such as Figure 3 As shown. Subsequently, after the coupling between the roller sleeve 2 and the calender 100 is released, the translation mechanism 4 can be used to drive the carrier mechanism 1 in a direction away from the calender 100, thereby separating the roller sleeve 2 from the calender 100. Subsequently, the rotation mechanism 3 is activated, causing the carrier to move toward a storage position for the roller sleeve 2 and, under the action of the translation mechanism 4, to a corresponding position. Finally, the carrier mechanism 1 is activated and releases its coupling with the roller sleeve 2, completing the storage of the roller sleeve 2.

[0050] When a roller sleeve 2 stored in the storage position needs to be installed on the calender 100, it is only necessary to repeat the above process in reverse order.

[0051] In some embodiments, the translation mechanism 4 includes an X-axis translation component 41 and a Y-axis translation component 42, and the rotation mechanism 3 is connected to one of the X-axis translation component 41 and the Y-axis translation component 42; and / or, the carrier mechanism 1 is located below any one of the X-axis translation component 41 and the Y-axis translation component 42.

[0052] like Figure 1 、 Figure 3-Figure 5 As shown, it can be seen that at this time the translation mechanism 4 is a two-way motion track in the air, including an X-direction translation component 41 and a Y-direction translation component 42 that can translate in two different directions perpendicular to each other, wherein the X-direction translation component 41 is installed on the Y-direction translation component 42 and can reciprocate along a fixed path in the X direction relative to the Y-direction translation component 42; the carrier mechanism 1 can be connected to the X-direction translation component 41 through the rotating mechanism 3 located above it.

[0053] It should be noted that designing the carrier mechanism 1 below the track is conducive to the carrier mechanism 1 to grasp and release the roller sleeve 2 relative to the storage position without being affected by the track; it also helps to lower the center of gravity of the roller changing device to ensure stable operation of the equipment.

[0054] The specific structure of the above-mentioned translation mechanism 4 is described below:

[0055] like Figure 1 and Figure 6 As shown, in some embodiments, the X-axis translation assembly 41 includes an X-axis bearing seat 411, an X-axis guide assembly and an X-axis drive assembly, wherein the X-axis guide assembly includes an X-axis guide rail 412 and an X-axis slide 413, and the X-axis bearing seat 411 slides with the X-axis guide rail 412 through the X-axis slide 413; the X-axis drive assembly includes a first motor 414, a first gear 415 and a first rack 416, the first motor 414 is fixedly mounted on a certain X-axis bearing seat 411, the first gear 415 is located at the output end of the first motor 414 and engages with the first rack 416, the first rack 416 is arranged parallel to the X-axis guide rail 412, and the first gear 415 can rotate under the drive of the first motor 414.

[0056] Specifically, in order to ensure that the X-direction guide assembly can provide a relatively stable guiding effect, the number of the above-mentioned X-direction guide assemblies is two and they are arranged in parallel along the same direction.

[0057] In order to better install and fix the above-mentioned components, the X-axis translation component 41 also includes a shipping member 417 arranged in a bar shape. The X-guide rail 412 and the first rack 416 are arranged along the length direction (i.e., the X direction) of the shipping member 417. The first motor 414 is located on the X-axis support seat 411 and is engaged with the first rack 416 through the first gear 415. The X-axis slide 413 formed on the X-axis support seat 411 slides with the X-guide rail 412. When the first motor 414 is started, it can guide the first motor 414 to drive the X-axis support seat 411 to slide along the guide path of the X-guide rail 412, and drive the carrier mechanism 1 connected thereto to move synchronously.

[0058] like Figure 1 As shown, at this time, the number of the above-mentioned X-direction bearing seat 411 is one, and two parallel X-direction slides 413 are symmetrically arranged on the lower surface of the X-direction bearing seat 411 and slideably cooperate with the X-direction guide rail 412 located on the transport member 417.

[0059] like Figure 1 and Figure 7 As shown, in some embodiments, the Y-direction translation assembly 42 includes a Y-direction bearing seat 421, a Y-direction guide assembly and a Y-direction drive assembly, wherein the Y-direction guide assembly includes a Y-direction guide rail 422 and a Y-direction slide 423, and the Y-direction bearing seat 421 slides with the Y-direction guide rail 422 through the Y-direction slide 423; the Y-direction drive assembly includes a second motor 424, a second gear 425 and a second rack 426, the second motor 424 is fixedly mounted on a certain Y-direction bearing seat 421, the second gear 425 is located at the output end of the second motor 424 and engages with the second rack 426, the second rack 426 is arranged parallel to the Y-direction guide rail 422, and the second gear 425 can rotate under the drive of the second motor 424.

[0060] Specifically, to ensure that the Y-direction guide assembly provides relatively stable guidance and that there is sufficient space beneath the guide mechanism to accommodate the rotation mechanism 3 and the carrier mechanism 1, the translation mechanism 4 further includes a frame 43. The Y-direction guide assembly is fixedly mounted on the frame 43 and can translate relative to the frame 43 in the Y direction. In this case, there are two Y-direction guide assemblies, which are arranged parallel to the same direction on the frame 43. Similarly, there are two Y-direction bearing seats 421, each of which slidably engages with the two parallel Y-direction guide rails 422 via an X-direction slide 413 located thereon.

[0061] In addition to the aforementioned structure, the translation mechanism 4 also includes a positioning pin drive unit 44, which is located on a Y-axis bearing seat 421 and is connected to the frame 43 via a positioning pin, thereby limiting the movement of the Y-axis translation assembly 42. The positioning pin drive unit 44 can lock the Y-axis translation assembly 42 after it is moved into position, preventing the roller sleeve 2 from shaking when it moves relative to the carrier mechanism 1 (i.e., when the roller sleeve 2 moves between the carrier mechanism 1 and the calender 100 or the storage device 5).

[0062] It should be noted that the two Y-axis bearing seats 421 are respectively connected to the two ends of the transport member 417 in the X-axis displacement assembly. At this time, the transport member 417 is located below the frame 43.

[0063] The second motor 424 in the Y-direction guide assembly is fixedly mounted on a Y-direction support seat 421 and meshes with the second rack 426 through the second gear 425. The Y-direction slide 423 formed on the Y-direction support seat 421 slides with the Y-direction guide rail 422 mounted on the frame 43, and when the second motor 424 is started, it guides the Y-direction support seat 421 to slide along the path guided by the Y-direction guide rail 422, and drives the transport member 417 connected thereto to move synchronously.

[0064] In this embodiment, the rotating mechanism 3 is located on the X-axis bearing seat 411 .

[0065] Of course, in other embodiments, the installation order of the X-direction displacement assembly and the Y-direction displacement assembly can also be adjusted so that the Y-direction displacement assembly is installed on the X-direction displacement assembly and the rotation mechanism 3 is installed on the Y-direction displacement assembly. This embodiment does not limit the installation order.

[0066] The structure of the rotating mechanism 3 is described below:

[0067] like Figure 8 As shown, the rotating mechanism 3 includes a rotating drive unit 31 and a slewing bearing 32. The rotating drive unit 31 is connected to the translation mechanism 4, and the slewing bearing 32 is connected to the carrier mechanism 1. A third gear 311 is installed on the output end of the rotating drive unit 31, and a fourth gear 321 is provided outside the slewing bearing 32 to engage with the third gear 311.

[0068] Specifically, the above-mentioned rotation drive unit 31 is installed on the X-direction support seat 411 and its output end is output downward through the X-direction support seat 411. The third gear 311 located at the output end of the rotation drive unit 31 can engage with the fourth gear 321 located outside the slewing bearing 32, thereby driving the fourth gear 321 to rotate, and driving the slewing bearing 32 and the carrier mechanism 1 to rotate synchronously, thereby realizing the adjustment of the direction of the carrier mechanism 1.

[0069] The connection structure between the carrier mechanism 1 and the rotation drive unit 31 is as follows: Figure 11 and Figure 12 shown.

[0070] The carrier mechanism 1 can be inserted into or pulled out of the roller sleeve 2 to transport, grab, and release the roller sleeve 2. To achieve this function, in some embodiments, the carrier mechanism 1 includes a carrier body 11 and a tensioning assembly 12. A plurality of tensioning adjustment holes 111 are formed on the peripheral side wall of the carrier body 11. The tensioning assembly 12 can extend or retract relative to the tensioning adjustment holes 111 to grab or release the roller sleeve 2. When the tensioning assembly 12 extends relative to the tensioning adjustment holes 111, the structure of the carrier mechanism 1 is as follows: Figure 9 When the tensioning assembly 12 is retracted relative to the tensioning adjustment hole 111, the structure of the carrier mechanism 1 is as shown Figure 10 By adjusting the position of the tensioning assembly 12, the carrier mechanism 1 can grasp and release the roller sleeve 2, and cooperate with the rotating mechanism 3 and the translation mechanism 4 to realize the transportation of the roller sleeve 2 during the adjustment process.

[0071] In some embodiments, the tensioning assembly 12 includes a tensioning driver 121 and a tensioning sheet 122, and its structure is as follows: Figure 11 and Figure 12 As shown, the tensioning driver 121 is a linear driver (such as a linear drive cylinder, etc.), and the tensioning piece 122 is hinged to the action end of the tensioning driver 121; when the tensioning driver 121 is started, the tensioning piece 122 can extend or retract relative to the tensioning adjustment hole 111.

[0072] It should be noted that the number of the tensioning components 12 is not less than the number of the tensioning adjustment holes 111 .

[0073] In some embodiments, the tensioning assembly 12 further includes a connecting rod 123, the ends of which are hingedly connected to the tensioning driver 121 and the tensioning plate 122. When the operating end of the tensioning driver 121 moves linearly, the connecting rod 123 swings under the action of the tensioning driver 121, driving the tensioning plate 122 to extend or retract relative to the tension adjustment hole 111.

[0074] In order to ensure a more stable combination of the tensioning assembly 12 and the roller sleeve 2 , in some embodiments, the number of the tensioning assembly 12 is at least two and they are evenly arranged along the circumference of the carrier body 11 .

[0075] like Figure 13 As shown, the carrier mechanism 1 includes four tensioning pieces 122 evenly arranged along the circumference of the carrier body 11 .

[0076] In some embodiments, a plurality of limiting grooves 113 are formed inside the vehicle body 11 , and the limiting grooves 113 are extended along the radial direction of the vehicle body 11 ; a positioning rod 124 is fixedly mounted on the tensioning plate 122 , and the positioning rod 124 is slidably connected to the limiting grooves 113 .

[0077] The limiting groove 113 can be used to limit the movement direction of the tensioning piece 122, ensuring that the tensioning piece 122 can always move in a direction perpendicular to the axis of the carrier body 11. The design of the limiting groove 113 can further position the tensioning piece 122, ensuring that the tensioning piece 122 can move stably and reciprocatingly along the set path, preventing the tensioning piece 122 from offsetting after multiple displacements, and ensuring that multiple tensioning pieces 122 can always move synchronously.

[0078] Specifically, in some embodiments, a notched plate 112 is further disposed within the carrier body 11. This notched plate 112 is perpendicular to the axis of the carrier body 11 and serves to divide the space within the carrier body 11 into two distinct areas. The main body of the tensioning actuator 121 is located on the inner side of the notched plate 112, while the tensioning plate 122 is located on the outer side of the notched plate 112. A through-hole is formed in the center of the notched plate 112, through which the actuating end of the tensioning actuator 121 extends. A supporting sliding seat 114 is fixedly mounted in the through-hole. The actuating end of the tensioning actuator 121 extends through the supporting sliding seat 114 and is connected to the connecting rod 123 via a sliding sleeve 115 at its end. The sliding sleeve 115 is a hollow annular structure, and one end of each of the connecting rods 123 is hinged to the sliding sleeve 115.

[0079] The tensioning assembly 12 can cooperate with the carrier body 11 to grasp and release roller sleeves 2 of various specifications within a certain size range.

[0080] In some embodiments, a storage device 5 is provided at the storage location, such as Figure 14 As shown, the storage device 5 is provided with a Z-direction lifting component 51 and a supporting platform 52 , and the supporting platform 52 can be raised and lowered under the drive of the Z-direction lifting component 51 .

[0081] Specifically, the Z-axis lifting assembly 51 is mounted below the support platform 52 and includes a Z-axis guide rail and a Z-axis actuator. There are at least two Z-axis guide rails, evenly spaced outside the Z-axis actuator. When the Z-axis actuator is activated and retracts, the Z-axis guide rails retract and retract accordingly, smoothly lifting and lowering the support platform 52.

[0082] The working mode of the above-mentioned roll changing device will be described below by taking the removal of the roll sleeve 2 installed on the calender 100 as an example:

[0083] First, under the action of the roller sleeve 2 removal device of the calender 100, the roller sleeve 2 is transferred to the carrier mechanism 1 in the installation position. The carrier mechanism 1 can fix and limit the roller sleeve 2 through the tensioning component 12 after the roller sleeve 2 is completely separated from the calender 100; then, the translation mechanism 4 and the rotation mechanism 3 are started in sequence or simultaneously according to the set requirements, so that the carrier mechanism 1 moves to the storage position and faces the storage device 5; finally, the lifting and lowering action of the storage device 5 is controlled and the supporting platform 52 lifts the roller sleeve 2. At this time, the carrier mechanism 1 releases the roller sleeve 2 through the tensioning component 12.

[0084] After the operation is completed, the carrier mechanism 1 can be placed at the current position, or the carrier mechanism 1 can be controlled to return to the initial position.

[0085] This embodiment also provides an automatic roller changing system, such as Figure 15-17 As shown, the automatic roll changing device includes a roll changing device, a calender 100 and a controller. The roll changing device is any of the roll changing devices described above. The calender 100 is located in the installation position. The controller is electrically connected to the roll changing device and the calender 100.

[0086] The controller may be a microprocessor or a central controller, or a specific integrated circuit or one or more integrated circuits configured to control the roll changing device and the related electronic control structures in the calender 100. The controller may control the working rhythm of the roll changing device and the calender 100 according to the relevant program running on the controller, thereby realizing the automatic replacement of the roll sleeve 2.
