Description

Technical Field

[0001] The present invention relates to the field of production equipment for tires, and more particularly to an automatic mold loading method for a tire vulcanizer based on an AGV. Background Art

[0002] In existing tire vulcanization processes, green tires are placed in tire molds (including upper molds and lower molds) for vulcanization production. When producing tires of different specifications or when the tire molds need to be repaired and maintained, the original tire molds need to be removed from the tire vulcanizer, and new tire molds need to be installed on the tire vulcanizer. The existing method is to replace the tire molds manually. Since the tire molds are large and heavy, it is extremely inconvenient to manually pick up, place, and transport them, and the efficiency is low. At the same time, there are also potential safety hazards. Based on this, the present invention provides an automatic mold loading method for a tire vulcanizer based on an AGV. Summary of the Invention

[0003] To solve the above technical problems, the present invention provides an automatic mold loading method for a tire vulcanizer based on an AGV, including the following steps: S21: Transport the mold placement tray carrying the tire mold to the lower mold change station by an AGV; S22: Accurately position the mold placement tray with the positioning mechanism of the tire vulcanizer, and lock the tire mold with the upper template assembly; S23: Lift the tire mold to the upper mold change station by a lifting mechanism; S24: Move the empty mold placement tray out of the tire vulcanizer by the AGV; S25: Lower the tire mold to the mold loading station by the lifting mechanism; S26: Lock and fix the lower mold.

[0004] The present invention mainly designs an automatic mold loading method for a tire vulcanizer based on an AGV to achieve automatic mold loading of tire molds, thereby replacing the original manual mold loading and handling. The degree of automation is high. And it is very easy to combine with existing AGV equipment, with simple operation, which helps to achieve full-process fully automated production in the tire production process.

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0023] As Figures 1 to 17 shown, the present invention provides a tire vulcanization system based on an AGV. The tire vulcanization system includes a tire vulcanizer 100 having a tire mold 40, and an AGV that can transport the tire mold 40 between the tire vulcanizer 100 and a designated position. The tire vulcanizer 100 includes a tire rack 10, an upper template assembly 31 movably disposed on the tire rack 10 through a lifting mechanism 20, a lower template assembly 32 disposed opposite to the upper template assembly 31. An upper mold 41 is disposed on the upper template assembly 31, a lower mold 42 is disposed on the lower template assembly 32, and a positioning mechanism 50 is further disposed on the lower template assembly 32; further includes a mold placement tray 200 used in cooperation with the positioning mechanism 50. The mold placement tray 200 is transported by the AGV and is used to load the tire mold 40. The tire mold 40 described in the present invention refers to the upper mold 41 and the lower mold 42 integrated together. The lifting mechanism 20 is a driving mechanism that can drive the upper template assembly 31 to move up and down, which can be an electric driving method, a hydraulic driving method or other forms of driving methods. The lifting mechanism 20 can be disposed on the upper template assembly 31, can also be disposed on the tire rack 10, or disposed at other positions. The accompanying drawings only illustrate the electric driving method disposed on the upper template assembly 31.

[0024] Through the tire vulcanizer 100 with the above structure, in cooperation with the AGV and the mold placement tray 200, when it is necessary to replace tire molds 40 of different specifications or the tire molds need to be repaired and maintained, the original tire mold can be automatically unloaded from the tire vulcanizer 100 and a new tire mold can be loaded onto the tire vulcanizer. The automatic mold unloading and automatic mold loading methods based on the AGV described in the present invention can be used alone or simultaneously.

[0025] The upper template assembly 31 described in the present invention can be an upper template or an upper template provided with upper heating elements, etc. The lower template assembly 32 can be a lower template or a lower template provided with lower heating elements, etc.

[0026] The present invention provides an automatic mold unloading method for a tire vulcanizer based on an AGV, including the following steps: S11: As Figure 2 and 3As shown in the figure, the original tire mold located on the tire vulcanizer 100 is lifted to the upper mold changing station by the lifting mechanism 20 of the tire vulcanizer. The upper mold changing station refers to the position after the entire tire mold 40 is lifted, and this position is used to avoid the AGV so that the AGV can extend into the tire vulcanizer.

[0027] S12: As Figure 4 shown in the figure, the AGV transports the empty mold placement tray 200 to the lower mold changing station, and the lower mold changing station refers to the position for loading the mold placement tray 200.

[0028] S13: The mold placement tray 200 is accurately positioned with the positioning mechanism 50 of the tire vulcanizer.

[0029] S14: As Figure 5 shown in the figure, the original tire mold located at the upper mold changing station is moved to the mold placement tray 200 by the lifting mechanism 20 and the original tire mold is released.

[0030] S15: As Figure 6 and 7 shown in the figure, the AGV moves the mold placement tray 200 loaded with the original tire mold out of the tire vulcanizer together.

[0031] Through the above method, by using the tire vulcanizer 100 in cooperation with the AGV, the automatic demolding of the tire mold 40 is realized, replacing the original manual demolding, thereby realizing rapid mold change and reducing the manual operation intensity.

[0032] It should be noted that the upper mold 41 and the lower mold 42 in the normal production process are respectively arranged on the upper template assembly 31 and the lower template assembly 32. Before demolding the tire mold 40, the separated upper mold 41 and lower mold 42 need to be combined into an integral tire mold 40 first. Preferably, before the step S11, there is also a step S111: As Figure 1 and 2 shown in the figure, the upper mold 41 is moved to the position where the lower mold 42 is located by the lifting mechanism 20, so that the upper mold 41 and the lower mold 42 are combined into an integral tire mold 40, and the lower mold 42 is automatically released by the lower mold locking device 60, so that the lower mold 42 is no longer fixedly arranged with the lower template assembly 32. The release step of the lower mold 42 and the step of combining the upper mold 41 and the lower mold 42 into an integral tire mold 40 can be carried out successively according to the specific production needs, or can also be carried out simultaneously. The tire mold 40 described in the present invention can combine or separate the upper mold 41 and the lower mold 42 manually, or can realize the automatic combination or separation of the upper mold 41 and the lower mold 42 through mechanical structures and manipulators. The lower mold locking device 60 described in the present invention can be any structure that can realize the automatic locking and separation functions of the lower mold 42 and the lower template assembly 32.

[0033] In step S14, the original tire mold 40 located at the upper die change station is moved to the position where the mold placing plate 200 is located by the lifting mechanism 20, and the tire mold 40 is placed on the mold placing plate 200. At the same time, the upper die locking device 70 automatically releases the upper die 41, so that the upper die 41 and the upper template assembly 31 are automatically separated. The upper die 41 is in a free state, and finally the separation of the tire mold 40 from the upper template assembly 31 is realized, and the tire mold 40 is placed on the mold placing plate 200. Of course, the automatic locking of the upper die 41 and the upper template assembly 31 can also be realized by the upper die locking device 70, and the upper die locking device 70 only needs to be able to realize the automatic locking and separation of the upper die 41 and the upper template assembly 31.

[0034] After step S15, step S16 may also be included. The AGV moves the mold placing plate 200 loaded with the original tire mold to a specified position together to temporarily store the original tire mold.

[0035] The present invention also provides an automatic die loading method for a tire vulcanizer based on an AGV, including the following steps: S21: As Figure 6 shown, the mold placing plate 200 carrying the new tire mold is transported to the lower die change station by the AGV.

[0036] S22: As Figure 5 shown, the mold placing plate 200 is accurately positioned with the positioning mechanism 50 of the tire vulcanizer, and the new tire mold is locked with the upper template assembly 31.

[0037] S23: As Figure 4 shown, the new tire mold is lifted to the upper die change station by the lifting mechanism 20, so as to facilitate the AGV to unload the mold placing plate.

[0038] S24: The AGV moves the empty mold placing plate 200 out of the tire vulcanizer.

[0039] S25: As Figure 3 and 2 shown, the new tire mold is lowered to the mold loading station by the lifting mechanism 20, so that the tire mold 40 contacts the lower template assembly 32, and the tire mold 40 is placed on the lower template assembly 32. The mold loading station refers to the position for placing the tire mold 40 on the lower template assembly 32.

[0040] S26: The lower die 42 is locked and fixed to the lower template assembly 32.

[0041] Before step S21, there is also step S211: Use an AGV to pick up the mold placement tray 200 loaded with a new tire mold from a specified location. The specified location can be a place such as a mold storage or a warehouse where the tire mold 40 is temporarily stored.

[0042] Preferably, the tire vulcanization system of the present invention may further include a preheating device (not shown). The preheating device is used to preheat the new tire mold that needs to be loaded onto the tire vulcanizer 100. By preheating the new tire mold in advance, the time required for the new tire mold to reach normal production from cold equipment can be shortened, and the production efficiency can be improved. Therefore, another implementation of step S211 is to use an AGV to pick up the mold placement tray 200 loaded with a new tire mold from the preheating device, and this mold placement tray 200 has been preheated by the preheating device.

[0043] Preferably, in order to ensure that the AGV transports the mold placement tray 200 loaded with a new tire mold to the lower die change station without interference from the upper template assembly 31 at the lower die change station, before performing step S21, there is also the upper template assembly 31 detection and judgment step S212: As Figure 7 shown, detect and judge whether the upper template assembly 31 is at the upper die change station. If the upper template assembly 31 is not at the upper die change station, lift the upper template assembly 31 to the upper die change station through the lifting mechanism 20. This can prevent the upper template assembly 31 from colliding with the AGV and the mold placement tray 200 at the lower die change station and damaging the equipment.

[0044] It should be noted that there is no necessary order requirement for the above steps S211 and S212, and the order can be set according to actual needs or they can be carried out simultaneously.

[0045] In step S22, move the upper template assembly 31 to contact the new tire mold through the lifting mechanism 20, and automatically lock and fix the new tire mold and the upper template assembly 31 through the upper die locking device 70. At this time, the upper die locking device 70 automatically locks the upper die 41 in the new tire mold and the upper template assembly 31, thereby realizing the automatic locking of the new tire mold and the upper template assembly 31.

[0046] Preferably, in order to ensure that the upper mold 41 is in contact with the upper template assembly 31 when the upper mold 41 and the upper template assembly 31 are automatically locked, in step S22, there is also a mold in-place detection and judgment step S221: detecting and judging whether the upper template assembly 31 is in contact with the new tire mold through a detection mechanism (not shown), and automatically locking the new tire mold and the upper template assembly 31 after detecting and judging that the upper template assembly 31 is in contact with the tire mold 40. Preferably, the detection mechanism includes a trigger element movably arranged on the upper template assembly 31, the trigger element protruding from the end face of the upper template assembly 31 close to the upper mold, and also includes a detection element. When the upper template assembly 31 is in contact with the tire mold 40, it will drive the position of the trigger element to move, and the detection element is used to detect the position change of the trigger element and feed back the position change to the control system, so as to judge whether the upper template assembly 31 is in contact with the tire mold 40.

[0047] Preferably, in step S26, the lower mold 42 and the lower template assembly 32 are automatically locked and fixed through the lower mold locking device 60, so as to realize automatically clamping the lower mold 42 onto the lower template assembly 32.

[0048] In the automatic mold loading method of the present invention, there is also a tire mold separation step S261: separating the tire mold 40 into an upper mold 41 and a lower mold 42, that is, the upper mold 41 and the lower mold 42 are no longer fixed together and can move separately. The tire mold separation step S261 can occur before step S26. At this time, the lower mold 42 in step S26 is the separate lower mold 42 after being separated from the upper mold 41. That is, after separating the tire mold first, then locking and fixing the lower mold 42 and the lower template assembly 32.

[0049] As another implementation manner, the tire mold separation step S261 can also occur after step S26. At this time, the lower mold 42 in step S26 is the upper mold 41 still connected to the upper mold in the tire mold 40. That is, first lock and fix the lower mold 42 in the overall tire mold to the lower template assembly 32, and then separate the tire mold 40 so that the upper mold 41 can move separately.

[0050] Such as Figures 8 to 11As shown in the figure, the mold placement tray 200 of the present invention includes a main support member 210, and a receiving space 211 for placing an AGV or other handling tools is provided on the main support member 210. The handling tool can pick up and place the mold placement tray 200 through the receiving space 211. One end of the main support member 210 in contact with the tire mold 40 is provided with a centering member 220 for centering the lower mold 42 in the tire mold. A first positioning member 230 is also provided on the main support member 210. The first positioning member 230 is used to cooperate with the positioning mechanism 50 on the lower template assembly 32 of the tire vulcanizer, so that when the mold placement tray 200 is placed in the tire vulcanizer for picking up and placing the tire mold 40, the position of the mold placement tray 200 can be accurately positioned and fixed.

[0051] As Figure 10 shown, the centering member 220 has a centering surface 221 that cooperates with the bottom of the lower mold 42. Preferably, the centering member 220 can be cylindrical or hollow annular, and the centering surface 221 is a circular surface, so as to better cooperate with the circular bottom of the lower mold 42, so that when the tire mold 40 is placed on the mold placement tray 200, the tire mold 40 is fixed and will not move. It should be noted that when the centering surface 221 cooperates with the bottom of the lower mold 42, the tire mold 40 will not move, and the tire mold 40 can easily move upward, that is, the tire mold 40 can easily be separated from the centering member 220.

[0052] As Figure 9 shown, preferably, the first positioning member 230 is a hollow structure, and a first guiding end 231 for guiding the positioning mechanism 50 and a first positioning end 232 for cooperating with the positioning mechanism 50 are provided inside the first positioning member 230. When the mold placement tray 200 is placed on the positioning mechanism 50 of the tire vulcanizer 100 or the temporary storage position from top to bottom, the positioning mechanism 50 enters the first positioning member 230 through the guiding of the first guiding end 231, so that the first positioning end 232 can be in good contact with the positioning mechanism 50 for positioning.

[0053] As Figure 10 and 11 shown, preferably, for a more reasonable layout, the first positioning member 230 is arranged inside the main support member 210. An installation hole 212 is provided inside the main support member 210. The installation hole has a first installation end 2121 for setting the first positioning member 230 and an avoidance end 2122 for accommodating the positioning mechanism 50. When the mold placement tray 200 is placed on the positioning mechanism 50, the positioning mechanism 50 is placed in the first installation end 2121 of the first positioning member and the avoidance end 2122 of the installation hole through the guiding of the first guiding end 231. The first positioning member 230 can be integrally or separately provided with the main support member 210.

[0054] It should be noted that the existing tire molds unloaded from the tire vulcanizer usually have a certain temperature. To prevent automatic handling tools such as AGVs from being damaged due to the temperature of the tire mold 40, the mold placement tray 200 of the present invention further includes a heat insulation member 240, and the heat insulation member 240 is disposed at one end of the main support member 210 close to the tire mold 40. The heat insulation member 240 is made of heat insulation material, so as to prevent the temperature of the tire mold 40 from being transmitted downward to the AGV or the handling tool. And when the new tire mold replaced on the tire vulcanizer has been preheated, by loading and transporting the new tire mold through the mold placement tray 200 with the heat insulation member 240, it can well prevent the new tire mold from reducing its temperature due to energy transfer.

[0055] Since the mold is heavy and the material of the mold is hard, to prevent the heat insulation material from being crushed or scratched by the mold, the mold placement tray 200 of the present invention is further provided with a protective layer 250 with a certain hardness, and the protective layer 250 is disposed above the heat insulation member 240 for contacting the tire mold 40.

[0056] As Figure 10 shown, since the mold specifications produced by different tire mold 40 manufacturers will not be exactly the same, that is, the inner diameter size of the circular bottom of the lower mold will change. To enable the mold placement tray to have a better range of use, the mold placement tray 200 of the present invention further includes an adjusting member 260 sleeved outside the centering member 220. Preferably, the adjusting member 260 is in a ring structure. When the inner diameter size of the circular bottom of the lower mold 42 in the tire mold 40 changes, by replacing the adjusting member 260 with different sizes, the adjusting member 260 can better cooperate with the bottom of the lower mold 42 to achieve position centering.

[0057] As Figure 8 and 9 shown, preferably, the positioning mechanism 50 of the present invention includes a plurality of second positioning members 51, and the second positioning members 51 include a second installation end 511, a second positioning end 512 that cooperates with the mold placement tray 200, and a second guiding end 513. Preferably, the second positioning end 512 is cylindrical, and the second guiding end 512 is conical.

[0058] As Figures 12 to 14As shown, preferably, the lower die locking device 60 of the present invention includes a lower locking drive mechanism 61 and a plurality of lower locking mechanisms 62 driven by the lower locking drive mechanism 61 (the plurality mentioned here also includes one lower locking mechanism 62, and one lower locking mechanism 62 can be driven by an independent lower locking drive mechanism 61). A plurality of lower die locking grooves 311 are provided on the lower template assembly 31. The lower locking mechanism 62 can move in the lower die locking grooves 311 under the drive of the lower locking drive mechanism 61, so as to automatically lock or release the lower die 42 placed on the lower template assembly 31.

[0059] As Figure 12 and 13 shown, the lower locking drive mechanism 61 includes a lower locking drive source 611 and a first transmission mechanism 612 driven by the lower locking drive source 611. The first transmission mechanism 612 includes a first transmission member 6121 arranged along the circumference of the lower template assembly 31 and in the lower die locking grooves 311, and a second transmission member 6122 arranged in the lower die locking grooves 311. The first transmission member 6121 and the second transmission member 6122 are coupled. Preferably, the first transmission member 6121 is a structure such as a chain or a steel cable, and the second transmission member 6122 can be a structure such as a gear or a sprocket. A plurality of the lower locking mechanisms 62 are fixed to the second transmission member 6122 at the same distance position in the lower die locking grooves 311. When the lower locking drive source 611 drives the second transmission member 6122 to move, the second transmission member 6122 drives a plurality of lower locking mechanisms 62 to move synchronously, so as to realize the synchronous movement of a plurality of lower locking mechanisms 62 in the lower die locking grooves 311 through the first transmission mechanism 612.

[0060] As Figure 14 shown, the lower locking mechanism 62 includes a support member 621 and a locking member 622 arranged in parallel with the support member 621 at a certain distance through a spacing adjusting member 624. The locking member 622 is connected to the support member 621 through an elastic component 623. After the locking member 622 contacts the lower die 42, it can be lifted upward relative to the support member 621 under force and receive a downward clamping force, so as to lock a part of the lower die 42 and the lower template assembly 32 located between the support member 621 and the locking member 622 through the downward clamping force received by the locking member 622.

[0061] The elastic component 623 includes a fixed shaft 6231 passing through the support member 621. The fixed shaft 6231 can move within the support member 621. The fixed shaft 6231 is connected to the locking member 622. A fixed shaft end 6232 is provided at one end of the fixed shaft 6231 close to the support member 621. It further includes a fastener 6233 for fixedly arranging the fixed shaft 6231 on the locking member 622. The elastic component 623 further includes a first elastic element 6234 sleeved on the fixed shaft 6231. The first elastic element 6234 is arranged between the support member 621 and the fixed shaft end 6232. When the locking member 622 contacts the lower mold 42 and the locking member 622 is lifted upward under the action of the force from the lower mold 42, the locking member 622 drives the fixed shaft 6231 to move upward, so that the first elastic element 6234 arranged between the support member 621 and the fixed shaft end 6232 is compressed. Since the support member 621 is arranged within the lower template assembly 32 and cannot move upward, the elastic restoring force of the first elastic element 6234 will act on the fixed shaft 6231 through the fixed shaft end 6232, causing the fixed shaft 6231 to be subjected to a downward force. Through the transmission of the force, the locking member 622 is subjected to a downward force, thereby locking the support member 621 and the locking member 622. Preferably, the first elastic element 6234 is a compression spring.

[0062] Such as Figures 15 to 17As shown, preferably, the upper mold locking device 70 of the present invention includes an upper locking drive source 711, a movable sliding seat 72 connected to the upper locking drive source 711, and a clamping mechanism 73 connected to the sliding seat 72. The clamping mechanism 73 includes a first clamping member 731 and a second clamping member 732 that are respectively movably arranged along a first direction (such as the horizontal direction F1). The first clamping member 731 can also move along a second direction (such as the vertical direction F2). A first locking groove 7311 is provided on the first clamping member 731, and a second locking groove 7321 is provided on the second clamping member 732. The first locking groove 7311 and the second locking groove 7321 are arranged opposite to each other. The first clamping member 731 and the second clamping member 732 can move towards each other or in opposite directions simultaneously along the first direction F1. When the first clamping member 731 reaches the locking position along the first direction F1 (the locking position refers to the position where, in the first direction F1, the first locking groove 7311 on the first clamping member 731 is in full contact with the mold locking screw 312. The mold locking screw 312 is pre-fixed on the upper mold 41 of the tire mold and passes through the upper template assembly 31. At this position, the first clamping member 731 cannot continue to move towards the second clamping member 732 in the first direction F1), the second clamping member 732 continues to move along the first direction F1, driving the first clamping member 731 to move along the second direction F2. When the first clamping member 731 moves along the second direction F2 to be in full contact with the locking end of the mold locking screw 312, so that the upper mold 41 contacts the upper template assembly 31 in the second direction F2, the first clamping member 731 and the second clamping member 732 lock the mold locking screw 312 passing through the upper template assembly 31 in the second direction F2, realizing automatic mold locking of the upper mold 41.

[0063] As Figure 16 As shown, a first inclined surface 7311 is provided on the first clamping member 731, and a second inclined surface 7321 is provided on the second clamping member 732. The first inclined surface 7311 and the second inclined surface 7321 are arranged in parallel. Through the above arrangement, when the first clamping member 731 reaches the locking position, the second clamping member 732 continues to move along the first direction towards the first clamping member 731 until it contacts the first clamping member 731. At this time, the second inclined surface 7321 of the second clamping member 732 contacts the first inclined surface 7311 of the first clamping member 731. Since the first clamping member 731 cannot continue to move towards the second clamping member 732 in the first direction F1, when the second clamping member 732 continues to move towards the first clamping member 731, the first inclined surface 7311 of the first clamping member 731 moves upward along the second direction F2 under the guidance of the second inclined surface 7321 of the second clamping member 732, realizing the movement of the first clamping member 731 along the second direction.

[0064] AsFigure 15 As shown, the first clamping member 731 is connected to the sliding seat 72 through a first connecting mechanism 74, and the second clamping member 732 is connected to the sliding seat 72 through a second connecting mechanism 75. A moving adjustment mechanism 76 is further provided on the first connecting mechanism 74. The moving adjustment mechanism 76 is used to ensure that when the first clamping member 731 reaches the locking position, the first clamping member 731 does not move in the first direction F1, and the second clamping member 732 continues to move in the first direction.

[0065] Specifically, the first connecting mechanism 74 includes a link assembly 741 and a rotating rod 742 that are hinged, and a support rod 743 connected to the middle position of the rotating rod 742. The rotating rod 742 is rotatably provided on the support rod 743. One end of the link assembly 741 away from the hinge with the rotating rod 742 is hinged to the sliding seat 72, and the end of the rotating rod 742 away from the hinge with the link assembly 741 is hinged to the first clamping member 731. The second connecting mechanism 75 is respectively hinged to the sliding seat 72 and the second clamping member 732. The link assembly 741 includes a fixed rod 7411 and a moving rod 7412. One end of the moving rod 7412 is movably provided within the fixed rod 7411. The moving adjustment mechanism 76 includes a moving groove 761 provided on the fixed rod 7411, and a fixing member 762 that can move within the moving groove 761 and is fixedly provided on the moving rod 7412. The fixing member 762 enables the moving rod 7412 to move within the range of the moving groove 761. It also includes a second elastic element 763 sleeved on the moving rod 7412. The second elastic element 763 is provided on a part of the moving rod 7412 outside the fixed rod 7411. When the moving rod 7412 moves towards the fixed rod 7411, the second elastic element 763 will be compressed.

[0066] Preferably, the upper locking drive source 711 of the present invention can be an independent drive source to drive one clamping mechanism, such as Figure 17 As shown, as another implementation manner, it further includes a second transmission mechanism 712 driven by the upper locking drive source 711. Through the second transmission mechanism 712, multiple groups of clamping mechanisms 73 are driven to move synchronously to lock multiple mold locking screws 312 simultaneously. Preferably, the second transmission mechanism 712 includes a gear 7121 and a first rack 7122 and a second rack 7123 that are relatively arranged and respectively meshed with the gear 7121. It also includes a first connecting link 7124 connected to the first rack 7122 and a second connecting link 7125 connected to the second rack 7123. The first connecting link 7124 and the second connecting link 7125 are respectively connected to two groups of sliding seats 72. Through the above settings, multiple clamping mechanisms 73 are driven to move synchronously by one upper locking drive source 711.
