Description

Technical Field

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

[0002] Existing tire vulcanization processes all involve placing a raw tire in a tire mold (including an upper mold and a lower mold) for vulcanization production. When producing tires of different specifications or when the tire mold requires maintenance, the original tire mold must be removed from the tire vulcanizer and a new tire mold installed. Existing methods all involve manual replacement of tire molds. Because tire molds are large and heavy, manual handling is extremely inconvenient and inefficient, and also poses a safety hazard. Based on this, the present invention provides an automatic mold unloading method for a tire vulcanizer based on an AGV. Summary of the Invention

[0003] In order to solve the above technical problems, the present invention provides an automatic demolding method of a tire vulcanizer based on AGV, comprising the following steps: S11: The tire mold is lifted to the upper mold changing station by the lifting mechanism of the tire vulcanizer; S12: The empty mold tray is transported to the next mold changing station by AGV; S13: Accurately positioning the mold placement plate and the positioning mechanism of the tire vulcanizer; S14: releasing the tire mold onto the mold placement plate; S15: The mold placement tray loaded with the tire mold is moved out of the tire vulcanizer by the AGV.

[0004] The present invention mainly designs an automatic mold unloading method for tire vulcanizers based on AGV, realizing automatic mold unloading of tire molds, thereby replacing the original manual mold unloading and mold handling, with a high degree of automation. It is also easy to combine with existing AGV equipment, simple to operate, and helps to achieve full automation of the entire tire production process. BRIEF DESCRIPTION OF THE DRAWINGS

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

[0023] like Figures 1 to 17 As shown, the present invention provides an AGV-based tire vulcanization system, which 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 location. The tire vulcanizer 100 includes a tire frame 10, an upper template assembly 31 movably arranged on the tire frame 10 by a lifting mechanism 20, and a lower template assembly 32 arranged opposite to the upper template assembly 31. The upper template assembly 31 is provided with an upper mold 41, the lower template assembly 32 is provided with a lower mold 42, and the lower template assembly 32 is also provided with a positioning mechanism 50; and further includes a mold placement tray 200 used in conjunction with the positioning mechanism 50, the mold placement tray 200 being transported by the AGV for loading the tire mold 40. The tire mold 40 described in the present invention refers to an upper mold 41 and a lower mold 42 combined into one body. The lifting mechanism 20 is a driving mechanism that can drive the upper template assembly 31 to move up and down. It can be an electric drive mode, or a hydraulic drive mode or other forms of drive mode. The lifting mechanism 20 can be set on the upper template assembly 31, or on the tire frame 10, or at other locations. The accompanying drawings only illustrate the electric drive mode set on the upper template assembly 31.

[0024] The tire vulcanizer 100 of the above structure, in conjunction with the AGV and the mold placement tray 200, can automatically remove the original tire mold from the tire vulcanizer 100 and load a new tire mold onto the tire vulcanizer when a tire mold 40 of a different specification needs to be replaced or when the tire mold requires maintenance. The automatic mold unloading and automatic mold loading methods based on the AGV of the present invention can be used separately or simultaneously.

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

[0026] The present invention provides an automatic demoulding method for a tire vulcanizer based on AGV, comprising the following steps: S11: Figure 2 and 3 As shown, 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, wherein the upper mold changing station refers to the position after the tire mold 40 is lifted as a whole, which is used to avoid the AGV so that the AGV can extend into the tire vulcanizer.

[0027] S12: Figure 4 As shown, the empty mold placement tray 200 is transported to the lower mold change station by the AGV, and the lower mold change station refers to a position for loading the mold placement tray 200.

[0028] S13: Precisely position the mold placement plate 200 and the positioning mechanism 50 of the tire vulcanizer.

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

[0030] S15: Figure 6 and 7 As shown, the mold placement tray 200 loaded with the original tire mold and the tire mold are moved out of the tire vulcanizer by the AGV.

[0031] Through the above method, by using the tire vulcanizer 100 in conjunction with the AGV, the tire mold 40 can be automatically unloaded, replacing the original manual unloading, thereby achieving rapid mold replacement and reducing the intensity of manual operation.

[0032] It should be noted that, in the normal production process, the upper mold 41 and the lower mold 42 are respectively arranged on the upper template assembly 31 and the lower template assembly 32. Before the tire mold 40 is unmolded, the separated upper mold 41 and the lower mold 42 need to be combined into an integral tire mold 40. Preferably, before step S11, step S111 is also included: Figure 1 and 2 As shown, the upper mold 41 is moved to the position of the lower mold 42 by the lifting mechanism 20, so that the upper mold 41 and the lower mold 42 are combined to form an integral tire mold 40, and the lower mold locking device 60 automatically releases the lower mold 42 so that the lower mold 42 is no longer fixed to the lower template assembly 32. The steps of releasing the lower mold 42 and combining the upper mold 41 and the lower mold 42 to form an integral tire mold 40 can be performed in sequence according to specific production needs, or can also be performed simultaneously. The tire mold 40 described in the present invention can be combined or separated manually by the upper mold 41 and the lower mold 42, or automatically combined or separated by a mechanical structure and a robot. The lower mold locking device 60 described in the present invention can be any structure as long as it can realize the automatic locking and separation function of the lower mold 42 and the lower template assembly 32.

[0033] In step S14, the existing tire mold 40 located at the upper mold changing station is moved to the location of the mold placement tray 200 by the lifting mechanism 20, and the tire mold 40 is placed on the mold placement tray 200. Simultaneously, the upper mold locking device 70 automatically releases the upper mold 41, automatically separating the upper mold 41 and the upper mold plate assembly 31. The upper mold 41 is in a free state, and the tire mold 40 is finally separated from the upper mold plate assembly 31, allowing the tire mold 40 to be placed on the mold placement tray 200. Of course, the upper mold locking device 70 can also be used to automatically lock the upper mold 41 and the upper mold plate assembly 31. The upper mold locking device 70 only needs to be able to automatically lock and separate the upper mold 41 and the upper mold plate assembly 31.

[0034] After step S15 , step S16 may be further included, in which the AGV moves the mold placement tray 200 loaded with the original tire mold to a designated location to temporarily store the original tire mold.

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

[0036] S22: Figure 5 As shown, the mold placement plate 200 is precisely 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: If Figure 4 As shown, the new tire mold is lifted to the upper mold changing station by the lifting mechanism 20, so that the AGV can unload the mold placement tray.

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

[0039] S25: Figure 3 and 2 As 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 a position for placing the tire mold 40 on the lower template assembly 32.

[0040] S26: Lock and fix the lower mold 42 to the lower template assembly 32.

[0041] Before step S21, the process further includes step S211: taking the mold placement tray 200 loaded with the new tire mold from a designated location by the AGV. The designated location may be a mold warehouse 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) for preheating a new tire mold to be loaded onto the tire vulcanizer 100. By preheating the new tire mold, the time required for the new tire mold to transition from a cold device to normal production is shortened, thereby improving production efficiency. Therefore, another embodiment of step S211 is to use an AGV to retrieve a mold tray 200 loaded with the new tire mold from the preheating device. The mold tray 200 has already been preheated by the preheating device.

[0043] Preferably, in order to ensure that the upper template assembly 31 does not interfere with the lower mold changing station when the AGV transports the mold placement tray 200 loaded with the new tire mold to the lower mold changing station, before performing step S21, the upper template assembly 31 detection and judgment step S212 is also included: Figure 7 As shown, the upper mold assembly 31 is detected and determined to be in the upper mold change station. If the upper mold assembly 31 is not in the upper mold change station, the upper mold assembly 31 is lifted to the upper mold change station by the lifting mechanism 20. This prevents the upper mold assembly 31 from colliding with the AGV and the mold placement tray 200 at the lower mold change station and damaging the equipment.

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

[0045] In step S22, the upper mold assembly 31 is moved into contact with the new tire mold by the lifting mechanism 20, and the new tire mold and the upper mold assembly 31 are automatically locked and fixed by the upper mold locking device 70. At this time, the upper mold locking device 70 automatically locks the upper mold 41 of the new tire mold with the upper mold assembly 31, thereby automatically locking the new tire mold and the upper mold assembly 31.

[0046] Preferably, to ensure that the upper mold 41 is in contact with the upper mold assembly 31 during automatic locking, step S22 further includes a mold position detection step S221: a detection mechanism (not shown) detects and determines whether the upper mold assembly 31 is in contact with the new tire mold. When the upper mold assembly 31 is detected and determined to be in contact with the tire mold 40, the new tire mold is automatically locked with the upper mold assembly 31. Preferably, the detection mechanism includes a movably disposed trigger element on the upper mold assembly 31, the trigger element protruding from an end surface of the upper mold assembly 31 proximal to the upper mold, and a detection element. When the upper mold assembly 31 contacts the tire mold 40, the trigger element moves. The detection element is configured to detect the position change of the trigger element and feed this position change back to the control system, thereby determining whether the upper mold 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 by the lower mold locking device 60 , thereby automatically locking the lower mold 42 to the lower template assembly 32 .

[0048] The automatic mold loading method of the present invention further includes a tire mold 40 separation step ( S261 ): separating the tire mold 40 into an upper mold 41 and a lower mold 42 . This separation allows the upper mold 41 and the lower mold 42 to be moved independently of each other. This tire mold separation step ( S261 ) can occur before step ( S26 ). In this case, the lower mold 42 in step ( S26 ) is a separate lower mold 42 separated from the upper mold 41 . Specifically, the tire mold is separated before the lower mold 42 is securely fastened to the lower mold assembly 32 .

[0049] As another embodiment, the tire mold separation step S261 can also occur after step S26. In this case, the lower mold 42 in step S26 is the upper mold 41 in the tire mold 40 that is still connected to the upper mold. That is, the lower mold 42 of the entire tire mold is first locked and fixed to the lower mold plate assembly 32, and then the tire mold 40 is separated, allowing the upper mold 41 to move independently.

[0050] like Figures 8 to 11As shown, the mold placement tray 200 described in the present invention includes a supporting main part 210, and the supporting main part 210 is provided with a accommodating space 211 for placing an AGV or other transporting tools, and the transporting tools can take and place the mold placement tray 200 through the accommodating space 211; the supporting main part 210 is provided with a centering part 220 on the end that contacts the tire mold 40 for centering the lower mold 42 in the tire mold, and the supporting main part 210 is also provided with a first positioning part 230, which 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 to take and place the tire mold 40, the position of the mold placement tray 200 is fixed.

[0051] like Figure 10 As shown, the centering member 220 has a centering surface 221 that mates with the bottom of the lower mold 42. Preferably, the centering member 220 can be cylindrical or hollow, and the centering surface 221 is a circular surface, thereby better mates with the circular bottom of the lower mold 42. When the tire mold 40 is placed on the mold placement plate 200, the tire mold 40 is fixed and does not move. It should be noted that when the centering surface 221 mates with the bottom of the lower mold 42, the tire mold 40 does not move and can easily move upward, that is, the tire mold 40 can easily separate from the centering member 220.

[0052] like Figure 9 As shown, preferably, the first positioning member 230 is a hollow structure, and the first positioning member 230 is provided with a first guide end 231 for guiding the positioning mechanism 50 and a first positioning end 232 that cooperates with the positioning mechanism 50. When the mold placement plate 200 is placed from top to bottom on the tire vulcanizer 100 or the positioning mechanism 50 in the temporary storage position, the positioning mechanism 50 is guided by the first guide end 231 and enters the first positioning member 230, so that the first positioning end 232 is in good contact with the positioning mechanism 50 for positioning.

[0053] like Figure 10 and 11 As shown, preferably, for a more rational layout, the first positioning member 230 is disposed within the main support member 210. The main support member 210 is provided with a mounting hole 212. The mounting hole has a first mounting end 2121 for mounting the first positioning member 230 and a relief end 2122 for accommodating the positioning mechanism 50. When the mold placement plate 200 is placed on the positioning mechanism 50, the positioning mechanism 50 is guided by the first guide end 231 and positioned within the first mounting end 2121 of the first positioning member and the relief end 2122 of the mounting hole. The first positioning member 230 can be integral with the main support member 210 or separately.

[0054] It should be noted that the existing tire molds removed from the tire vulcanizer are usually at a certain temperature. In order to prevent automatic handling tools such as AGVs from being damaged by the temperature of the tire mold 40, the mold placement tray 200 of the present invention also includes a heat insulating member 240, which is arranged on one end of the support main component 210 near the tire mold 40. The heat insulating member 240 is made of a heat insulating material, thereby preventing the temperature of the tire mold 40 from being transferred downward to the AGV or handling tool. In addition, when the new tire mold replaced on the tire vulcanizer is preheated, loading and handling the new tire mold through the mold placement tray 200 with the heat insulating member 240 can effectively prevent the new tire mold from lowering its temperature due to energy transfer.

[0055] Since the mold is heavy and made of a hard material, in order to prevent the insulation material from being crushed or scratched by the mold, the mold placement plate 200 described in the present invention is also provided with a protective layer 250 of a certain hardness. The protective layer 250 is provided above the insulation part 240 for contacting the tire mold 40.

[0056] like Figure 10 As shown, since the mold specifications of tire molds 40 produced by different manufacturers vary, namely, the inner diameter of the circular bottom of the lower mold may vary, to improve the usability of the mold placement tray, the mold placement tray 200 of the present invention also includes an adjustment member 260 that is disposed outside the centering member 220. Preferably, the adjustment member 260 is a circular ring structure. When the inner diameter of the circular bottom of the lower mold 42 in the tire mold 40 changes, by replacing the adjustment member 260 with a different size, the adjustment member 260 and the bottom of the lower mold 42 can better cooperate and achieve centering.

[0057] like Figure 8 and 9 As shown, preferably, the positioning mechanism 50 of the present invention includes a plurality of second positioning members 51, each of which includes a second mounting end 511, a second positioning end 512 that cooperates with the mold placement plate 200, and a second guide end 513. Preferably, the second positioning end 512 is cylindrical, and the second guide end 512 is conical.

[0058] like Figures 12 to 14As shown, preferably, the lower mold locking device 60 described in 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 described here also includes a lower locking mechanism 62, and a lower locking mechanism 62 can be driven by an independent lower locking drive mechanism 61), and a plurality of lower mold locking grooves 311 are provided on the lower template assembly 31, and the lower locking mechanism 62 can be moved in the lower template locking groove 311 by the drive of the lower locking drive mechanism 61, thereby automatically locking or releasing the lower mold 42 placed on the lower template assembly 31.

[0059] like Figure 12 and 13 As 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 disposed along the circumference of the lower template assembly 31 and within the lower template locking groove 311, and a second transmission member 6122 disposed within the lower template locking groove 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 is a structure such as a gear or a sprocket. Several of the lower locking mechanisms 62 are fixed to the second transmission member 6122 at the same distance position of the lower template locking groove 311. When the lower locking drive source 611 drives the second transmission member 6122 to move, the second transmission member 6122 drives several of the lower locking mechanisms 62 to move synchronously, thereby realizing the synchronous movement of several of the lower locking mechanisms 62 in the lower template locking groove 311 through the first transmission mechanism 612.

[0060] like Figure 14 As shown, the lower locking mechanism 62 includes a support member 621, and a locking member 622 arranged parallel to the support member 621 at a certain distance through a spacing adjustment member 624, and the locking member 622 is connected to the support member 621 through an elastic component 623, wherein the locking member 622 is subjected to a force after contacting the lower mold 42 to be lifted upward relative to the support member 621 and subjected to a downward clamping force, thereby locking the portion of the lower mold 42 and the lower template assembly 32 located between the support member 621 and the locking member 622 through the downward clamping force exerted on the locking member 622.

[0061] The elastic component 623 includes a fixed shaft 6231 that passes through the support member 621, and the fixed shaft 6231 can move within the support member 621. The fixed shaft 6231 is connected to the locking member 622. The fixed shaft 6231 is provided with a fixed shaft end 6232 at one end close to the support member 621, and also includes a fastener 6233 that fixes the fixed shaft 6231 on the locking member 622; the elastic component 623 also includes a first elastic element 6234 that is sleeved on the fixed shaft 6231, and 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 is lifted upward by the force of the lower mold 42, the locking member 622 drives the fixed shaft 6231 upward, compressing the first elastic element 6234 disposed between the support member 621 and the fixed shaft end 6232. Since the support member 621 is disposed within the lower mold assembly 32 and cannot move upward, the elastic restoring force of the first elastic element 6234 acts on the fixed shaft 6231 through the fixed shaft end 6232, causing the fixed shaft 6231 to be subjected to a downward force. Through force transmission, the locking member 622 is also 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] like Figures 15 to 17As shown, preferably, the upper mold locking device 70 described in 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, wherein the clamping mechanism 73 includes a first clamping member 731 and a second clamping member 732 which are movably arranged along a first direction (such as a horizontal direction F1), and the first clamping member 731 can also be moved along a second direction (such as a 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, and the first locking groove 7311 and the second locking groove 7321 are arranged opposite to each other; the first clamping member 731 is provided with a first locking groove 7311, and the second locking groove 7321 is provided with a second locking groove 7321. The first clamping member 731 and the second clamping member 732 can move toward 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 in the first direction F1 where the first locking groove 7311 on the first clamping member 731 is in full contact with the locking screw 312, the locking screw 312 being pre-fixed on the upper mold 41 of the tire mold and passing through the upper mold assembly 31. At this position, the first clamping member 731 cannot continue to move in the first direction F1 toward the direction approaching the second clamping member 732), the second clamping member 732 continues to move in the first direction F1, driving the first clamping member 731 to move in the second direction F2. When the first clamping member 731 moves along the second direction F2 to fully contact the locking end of the 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 locking screw 312 passing through the upper template assembly 31 in the second direction F2, thereby realizing automatic locking of the upper mold 41.

[0063] like Figure 16 As shown, the first clamping member 731 is provided with a first inclined surface 7311, and the second clamping member 732 is provided with a second inclined surface 7321, and the first inclined surface 7311 is arranged parallel to the second inclined surface 7321. 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 toward 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 can no longer move toward the second clamping member 732 in the first direction F1, when the second clamping member 732 continues to move toward the first clamping member 731, the first inclined surface 7311 of the first clamping member moves upward along the second direction F2 under the guidance of the second inclined surface 7321 of the second clamping member, thereby realizing the movement of the first clamping member 731 in the second direction.

[0064] like Figure 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. It also includes a movement adjustment mechanism 76 arranged on the first connecting mechanism 74. The movement adjustment mechanism 76 is used to achieve 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 hinged connecting rod assembly 741 and a rotating rod 742, and a support rod 743 connected to the middle position of the rotating rod 742. The rotating rod 742 is rotatably arranged on the support rod 743. The end of the connecting rod assembly 741 away from the hinged connection with the rotating rod 742 is hinged to the sliding seat 72. The end of the rotating rod 742 away from the hinged connection with the connecting rod assembly 741 is hinged to the first clamping member 731. The second connecting mechanism 75 is hinged to the sliding seat 72 and the second clamping member 732 respectively. The connecting rod assembly 741 includes a fixed rod 7411 and a movable rod 7412. One end of the movable rod 7412 is movably arranged within the fixed rod 7411.
