Description

Technical Field

[0001] This utility model belongs to the field of tires, specifically relating to a simple single-station tire blank storage device. Background Technology

[0002] A tire holder is a device for storing tire blanks placed before a tire vulcanizing machine. After the tire molding process, the tire blank is placed in the tire holder belonging to the tire vulcanizing machine so that the machine's robotic arm can grasp it for the vulcanization process. Therefore, the proper storage of tire blanks in the tire holder is crucial for the vulcanization process.

[0003] Under normal circumstances, each tire vulcanizing machine is equipped with a tire keeper at least one to one according to its vulcanization level, that is, one tire keeper for each vulcanization chamber, in order to reduce the proportion of non-vulcanization time in the tire vulcanization process. Currently, in addition to the most basic function of storing tire blanks, tire keepers not only assist in radial centering of the tire blank so that the tire vulcanizing machine's tire-loading robot can accurately grasp it, but also help restore the rubber near the bead caused by the tire's own weight over a long period of time, reducing the risk of tire vulcanization defects and the labor intensity of workers.

[0004] Most current tire storage devices adopt a semi-steel green tire storage device disclosed in CN107804009A. Specifically, it forms an L-shaped structural space with its support part to hold the tire blank, and the position of the support part is adjusted to make corresponding adaptations.

[0005] However, there is a drawback in the above process: the mechanical gripper needs to maintain high precision when grasping the embryo in order to place the embryo in the internal space it forms. At the same time, it needs to maintain a stable state during the downward process. Otherwise, because the space formed after adjusting the position of the support part is highly compatible with the embryo, if it is not placed stably, there may be problems with the embryo not being placed in place. These situations either result in high manufacturing and operation costs for the equipment or make the equipment prone to construction errors. Utility Model Content

[0006] Details of one or more embodiments of the present invention are set forth in the following drawings and description to make other features, objects and advantages of the present application more readily apparent.

[0007] This utility model provides a simple single-station tire holder. By adopting a hinged rotating structure, the upper interface is relatively large when the tire is not placed, so precise docking is not required. After being lowered, the upper interface gradually shrinks and forms a central adjustment due to the weight of the tire itself, thus forming a more reliable clamping state.

[0008] A simplified single-station tire preform storage device, characterized in that it includes:

[0009] Tractor platform;

[0010] At least three support legs are arranged in a circular array on the support platform, and each support leg is hinged with a folding plate by a pin.

[0011] The second roller and the first roller are respectively disposed on the folding plates on the inner and outer sides of the pin shaft, and abut against the side and bottom of the tire blank through the included angle space formed between the first roller, the pin shaft and the second roller;

[0012] An angle limiter is used to adjust the deflection angle of the folding plate and make the diameter of the circumference formed by the plurality of first rollers in the included angle space when the tire blank is not placed larger than the diameter of the circumference formed by the plurality of first rollers when the tire blank is placed.

[0013] In some embodiments, the angle limiter is a compression spring; the compression spring is disposed between the support leg and the folding plate.

[0014] In some embodiments, the angle limiter is a counterweight; the counterweight is disposed on the folding plate and located on one side of the second roller.

[0015] In some embodiments, the included angle formed between the first roller, the pin, and the second roller is an obtuse angle.

[0016] In some embodiments, the distance between the pin and the second roller is greater than the distance between the pin and the first roller.

[0017] In some implementations, it also includes:

[0018] The display and control unit includes a sensing unit for monitoring the deflection state of the folding plate and a feedback unit for issuing a prompt signal for the deflection state of the folding plate.

[0019] The sensing unit is a tilt sensor, and the feedback unit is a signal light.

[0020] In some implementations, it also includes:

[0021] Multiple adjusting rods are evenly distributed around the center of the circumferential array and radiate outwards along its radial direction, with each of the legs slidingly mounted on each of the adjusting rods;

[0022] A ranging device is used to monitor the distance between each of the legs and the center of the circumferential array.

[0023] In some embodiments, the lower part of the support leg has an inner hollow structure and is fitted onto the adjusting rod.

[0024] In some embodiments, the radial cross-section of the adjusting rod is a cuboid structure, and multiple pin holes are provided along its axial direction; the lower part of the support leg is provided with a pin hole that matches the pin holes.

[0025] In some embodiments, the support platform includes:

[0026] The upper tray and the lower tray are separated by a gap, and the inner end of the adjusting rod is embedded and fixed in the gap;

[0027] The chassis is located below the lower tray, and a telescopic rod is provided between the two.

[0028] Compared with the prior art, the present invention has the following advantages:

[0029] By using a hinged structure, the first roller provides more space when not in storage, greatly reducing the precision requirements of the corresponding mechanical parts and achieving true simplicity and efficiency, while ensuring reliable and stable clamping. Meanwhile, in traditional storage structures, the force support for the tire blank is mostly on the lower side of the blank, making it difficult to provide reliable clamping support for the crown. This force deviation increases the probability of deformation deviation on the upper and lower sides of the blank. However, this application, based on the hinged structure, allows the first roller to apply a clamping force to the crown of the blank during the downward movement, thereby reducing the force on the lower side of the blank.

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described and explained below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments provided by this utility model without inventive effort are within the scope of protection of this utility model.

[0036] Obviously, the accompanying drawings described below are merely some examples or embodiments of this utility model. Those skilled in the art can apply this utility model to other similar scenarios without any creative effort. Furthermore, it is understood that although the efforts made in this development process may be complex and lengthy, for those skilled in the art related to the content disclosed in this utility model, any changes to the design, manufacturing, or production methods based on the disclosed technical content are merely conventional technical means and should not be construed as insufficient disclosure of this utility model.

[0037] In this utility model, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this utility model. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this utility model may be combined with other embodiments without conflict.

[0038] A simplified single-station tire preform storage device includes:

[0039] Tractor platform 1;

[0040] At least three support legs 2 are arranged in a circular array on the support platform 1, and each support leg 2 is hinged with a folding plate 3 by a pin.

[0041] The second roller 5 and the first roller 4 are respectively disposed on the folding plates 3 on the inner and outer sides of the pin shaft, and abut against the side and bottom of the tire blank through the included angle space formed between the first roller 4, the pin shaft and the second roller 5.

[0042] An angle limiter is used to adjust the deflection angle of the folding plate 3, and to make the circumferential diameter of the included angle space formed by the plurality of first rollers 4 in the state without the tire blank larger than the circumferential diameter formed by the plurality of first rollers 4 in the state with the tire blank placed.

[0043] When the tire blank is not stored, the first roller 4 expands outward to form a larger opening range, making it easier to accept and dock with the robotic arm holding the tire blank. During the lowering process, affected by the weight of the tire blank itself, the first roller 4 retracts inward and applies a resisting force, which not only achieves the central setting and reliable clamping and storage, but also offsets part of the load-bearing capacity of the second roller 5, so as to reduce the force on the lower side of the tire blank.

[0044] In some embodiments, the angle limiter is a compression spring; the compression spring is disposed between the support leg 2 and the folding plate 3.

[0045] The reset function is achieved by the compression spring. When the compression spring is not under force, the first roller 4 naturally expands outward. When the tire carcass is stored, the first roller 4 contracts inward, applying tension to the compression spring. The compression spring becomes longer, giving the first roller 4 room to deflect. After the tire carcass is removed, the compression spring resets and pulls the first roller 4 back to its initial state, that is, the naturally outward expansion state.

[0046] Similarly, it can also be set as a hinge spring, located at the pin, similar to a hinged reset door panel.

[0047] In some embodiments, the angle limiter is a counterweight; the counterweight is disposed on the folding plate 3 and located on one side of the second roller 5.

[0048] Similarly, a counterweight structure can be used to reset the first roller 4 by means of counterweight, thereby ensuring that the first roller 4 naturally expands outward to form a larger opening range when the tire blank is not stored.

[0049] In some embodiments, the included angle formed between the first roller 4, the pin, and the second roller 5 is an obtuse angle. The distance between the pin and the second roller 5 is greater than the distance between the pin and the first roller 4. This structural arrangement makes the overall structure more rational and its stability higher.

[0050] In some embodiments, it also includes:

[0051] The display and control unit includes a sensing unit for monitoring the deflection state of the folding plate 3 and a feedback unit for issuing a deflection state prompt signal for the folding plate 3.

[0052] The sensing unit is a tilt sensor, and the feedback unit is a signal light.

[0053] Specifically, if the tire embryo is not stored, the sensor unit detects this state and sends a green light signal to the operator; if the tire embryo is stored, the sensor unit detects this state and sends a red light signal to the operator. This allows for quick differentiation. The reason for this setup is that, typically, there are 5-8 support legs 2 to more evenly store the tire embryo, thus requiring more reliable alerts and feedback.

[0054] In some embodiments, it also includes:

[0055] Multiple adjusting rods 7 are evenly distributed around the center of the circumferential array and are arranged outward in the radial direction, with each of the legs 2 slidably mounted on each of the adjusting rods 7;

[0056] A ranging device is used to monitor the distance between each of the legs 2 and the center of the circumferential array.

[0057] The above structure allows for the adaptation of different sizes of tire blanks, thereby increasing the applicability of the equipment.

[0058] Specifically, the lower part of the support leg 2 has an inner hollow structure and is fitted onto the adjusting rod 7. The radial cross-section of the adjusting rod 7 is a cuboid structure, and multiple pin holes 8 are provided along its axial direction; the lower part of the support leg 2 is provided with a pin hole that matches the pin holes 8.

[0059] The cuboid structure prevents the outrigger 2 from deflecting, improving the ease of adjustment. Meanwhile, the ranging device can use a conventional ruler or a corresponding sensing ranging unit, and can be matched and selected according to actual cost requirements.

[0060] In some embodiments, the support platform 1 includes:

[0061] The upper tray 11 and the lower tray 12 are separated by a gap, and the inner end of the adjusting rod 7 is embedded and fixed in the gap.

[0062] The chassis 10 is located below the lower tray 12, and a telescopic rod 9 is provided between the two.

[0063] The structure of the support platform 1 makes the installation and fixing of the adjusting rod 7 more secure, while the addition of the telescopic rod 9 further increases the applicability and versatility of the equipment.

[0064] Its working principle is as follows:

[0065] Based on the size range of the tire blank, the specific position of the support leg 2 is adjusted. A pin is inserted between the pin hole 8 and the pin hole to achieve relative fixation of the position. When the relative size variation of the tire blank storage area is small, fine-tuning of the distance is not required. The expansion and contraction range of the first roller 4 is utilized to simplify the corresponding process steps.

[0066] The robotic arm picks up the tire carcass and transports it above the support platform 1. Precise alignment is not required; simply placing it within the approximate opening of the first roller 4 in its expanded state allows for lowering. During lowering, the first roller 4 retracts inward under the tire carcass's own weight, contacting the crown of the carcass and automatically centering it. Simultaneously, the clamping contact between the first roller 4 and the carcass's crown partially offsets the load on the second roller 5, reducing the force on the lower side of the carcass. Both the first roller 4 and the second roller 5 are rotatably connected to the folding plate 3, further enhancing the stability and reliability of the lowering process.

[0067] During the placement or retrieval process, the status identification of the first roller 4 can be implemented in accordance with the scheme of the aforementioned embodiment to ensure the normal operation of the equipment.

[0068] After the embryo is removed, the counterweight 6 applies a downward force to one end of the first roller 4, causing the first roller 4 to return to its original position and be in a larger opening range, thus preparing it for the next storage operation.

[0069] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
