Description

Technical Field

[0001] This utility model relates to the field of tire production equipment technology, specifically to an anti-marking tire blank storage tray for storing and transferring tire blanks. Background Technology

[0002] In the tire manufacturing process, after the tire blank is formed, it needs to be temporarily stored and transferred on a dedicated storage pallet to facilitate its subsequent orderly entry into the vulcanization process. Currently, the tire blank storage pallets commonly used in the industry exhibit several major problems in practical application: First, due to unreasonable design of the pallet support blocks, the bead area of ​​the tire blank often touches the edge of the support block, while the shoulder area fails to make effective contact; instead, the sidewall area contacts the support block. This improper support condition leaves obvious marks on the soft sidewall of the tire blank. These marks cannot be eliminated during the subsequent high-temperature vulcanization process and easily develop into a quality defect of insufficient rubber on the sidewall, seriously affecting the final quality and pass rate of the tire product. Second, some pallet support blocks or the pallet body structure protrude outwards. In automated storage and retrieval systems (AS / RS), when the stacker crane's pins are used to pick up and place pallets, the pins are prone to interference and collision with the pallet support blocks. This not only affects the efficiency of automated transfer but also poses a risk of damaging equipment and tire blanks, resulting in low operational safety.

[0003] Furthermore, traditional pallets are often designed to be quite thick and heavy in order to achieve structural strength, resulting in a significant weight. This increases energy consumption during frequent transfers and also creates inconvenience for manual operation (when human intervention is required). Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a tire blank storage tray that prevents imprints from forming on the side of the tire blank through dual optimization of structure and materials. It is compatible with the automated picking and placing operation of stacker cranes in automated warehouses, and is also lighter in weight, making it easier to transport.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A tire blank storage tray designed to prevent scratches, the tray comprising a plurality of support members for supporting the tire blanks, the plurality of support members being circumferentially spaced and enclosing to form a support ring, the plurality of support members comprising:

[0007] The base is used for fixed connection to the ground;

[0008] The support portion is fixedly connected at its bottom to the top of the base portion. The support portion is made of elastic cushioning material. The support portion has a support top surface for contacting and supporting the tire shoulder, and a relief slope extending downward from the inner edge of the support top surface.

[0009] The clearance ramp is configured to maintain a non-contact gap with the tire side and the bead portion of the tire when the tire is placed on the support top surface.

[0010] The beneficial effects of this utility model are as follows:

[0011] This invention ensures that the tire embryo is supported by the strongest part of the tire shoulder, while the soft sidewalls and vulnerable calves are suspended in the air, avoiding hard contact.

[0012] The open support structure provided by this invention offers an unobstructed operating channel for the stacker crane's feet, enabling efficient and safe integration with automated storage and retrieval systems. By abandoning the traditional monolithic structure and adopting an independent support design, it significantly reduces material usage, lowers weight and manufacturing costs, while also facilitating localized maintenance and replacement, resulting in greater economic benefits.

[0018] 200 - rib, 100 - shoulder, 300 - sidewall. Detailed Implementation

[0019] The following will be illustrated with the accompanying drawings. Figures 1-3 The technical solution of this utility model will be described in detail through specific embodiments.

[0020] The shoulder 100 is the transition area between the tread and the sidewall 300. In the tire blank 1 structural design, this area has the thickest rubber compound and the densest internal ply layers, steel wire bundles, and other skeleton materials, forming the part with the highest structural strength and best rigidity in the entire tire blank 1. It bears the stored weight of the entire tire blank 1 and will not undergo irreversible plastic deformation. The sidewall 300 area is the softest and thinnest. The main function of the sidewall 300 is to provide sufficient flexibility when the tire rolls. Therefore, the rubber compound in this part is the thinnest, and the number of skeleton material layers is small, making it extremely soft. In the green tire state, the sidewall 300 is like uncured soft rubber; any slight contact or pressure is enough to leave permanent indentations or wrinkles on its surface. The bead 200 area is rigid but vulnerable. The bead 200 is wrapped with a high-strength steel wire ring, so it is extremely rigid. However, the bead 200 is a precision part for assembly with the wheel hub, and its surface finish and geometry are crucial. During storage, if the edge of the bead 200 collides or makes point contact with the support member 2, it may not only cause dents but also damage the bond between the internal steel wires and the rubber compound. This damage is insidious and cannot be repaired after vulcanization, seriously affecting the tire's driving safety. In the subsequent vulcanization process, the tire carcass 1 is placed in a high-temperature mold. Under the influence of internal pressure and temperature, the rubber compound flows and fills the mold cavity, ultimately forming the tire's tread pattern and outline. If there are already indentations on the sidewall 300 of the green tire, the density and flow characteristics of the rubber compound in that area have changed. During vulcanization, these indentations will become stress concentration points and trap air, preventing the rubber compound in that area from fully filling the mold, thus directly transforming into the irreversible defect of insufficient rubber in the sidewall 300, rendering it unusable. Because the shoulder 100 has a robust structure, it will not undergo harmful deformation when in contact with the support member 2. Even if there is slight contact stress, it will be completely eliminated under the strong hot and pressure action of the vulcanization process and will not remain on the final product. Based on the above technical facts, this utility model provides a storage tray for anti-mark tire blank 1 by designing a support point on the tire shoulder 100 to protect the most vulnerable sidewall 300 and the most delicate and fragile bead 200.

[0021] Example 1

[0022] The anti-marking tire blank 1 storage tray consists of four independent support members 2. Each support member 2 includes a base 22 and a support portion 21. The base 22 is a base with mounting holes, which is directly fixed to a predetermined position on the floor of the production workshop by anchor bolts. The four support members 2 form a stable support ring. The tire blank 1 is placed directly on these four support members 2 to complete the storage.

[0023] Support component 2 is installed independently, and its layout can be flexibly adjusted according to the specifications of pallet 1. Maintenance only requires replacing a single damaged support component 2, eliminating the need to scrap the entire pallet, resulting in excellent economy and applicability. Due to the lack of obstruction, the gaps between support components 2 create an unobstructed passageway, allowing stacker crane feet to freely enter and exit, and facilitating the loading and unloading of pallet 1 without any obstacles, greatly improving the efficiency and operational safety of automated warehouse transfers. Simultaneously, it reduces material usage, significantly lightening the weight, lowering energy consumption, and substantially saving manufacturing costs.

[0024] The support portion 21 is made of rubber. Utilizing the elasticity and damping properties of rubber, it provides flexible contact when supporting the tire carcass 1, effectively absorbing and dispersing stress, and preventing initial indentations caused by rigid impacts. The distribution circle formed by the center points of the support top surfaces 211 of the four support members 2 has a diameter of 500mm. This dimension is crucial to ensuring that the rigid bead 200 of the tire carcass 1 is completely within the support ring after the tire carcass 1 is firmly seated. It fundamentally avoids any risk of collision between the bead 200 and the upper edge of the support portion 21, forming the basis for a non-contact gap. The angle between the avoidance ramp 212 and the horizontal plane is 45°. This angle is the most versatile choice, guiding tire carcasses 1 of different sizes so that their shoulders 100 naturally fall into the support top surface 211, while providing maximum avoidance space for the sidewall 300 profile, ensuring that the gap always exists.

[0025] The supporting top surface 211 is an arc-shaped surface adapted to the curvature of the tire shoulder 100 of the tire blank 1, and it transitions smoothly with the avoidance slope 212 through a curved surface. The arc-shaped surface increases the contact area, and the smooth transition prevents the formation of cutting marks on the contact line.

[0026] Optionally, a microporous foam layer is laminated onto the top surface 211 of the support portion 21. This foam material is extremely soft and can further alleviate concentrated stress, providing protection.

[0027] Four support members 2 are arranged in a cross shape on the frame. The wide gap between the support members 2 forms an unobstructed passage for the stacker crane's feet, allowing the feet to freely extend in to pick up and put in the tire blank 1, which is perfectly compatible with the automated warehouse system.

[0028] It is understood that the number of support members 2 in this invention can be flexibly configured according to actual needs. For small tire blanks 1, three support members 2 can be arranged in an equilateral triangle. For standard-sized tire blanks 1, a cross-shaped symmetrical arrangement of four support members 2 is the optimal choice, which can provide good space for automated operation while ensuring stability. For large or heavy tire blanks 1, five or more support members 2 can be arranged in a uniform ring to provide a more sufficient distribution of support force.

[0029] The tire blank 1 is vertically lowered onto a support ring consisting of four independent support members 2 by a robotic arm or manually. The shoulder 100 of the tire blank 1 first contacts the arc-shaped top surface 211 of the elastic support 21, whereby the weight is cushioned and distributed. Simultaneously, thanks to the 500mm distribution diameter and the 45° clearance slope 212, the sidewall 300 and bead 200 of the tire blank 1 automatically form and maintain a safe, non-contact gap with the clearance slope 212 of the support member 21 in the radial direction. Throughout the storage cycle, the tire blank 1 is supported only by four flexible points at its strongest shoulder, with the vulnerable parts remaining completely contactless and stress-free, thus reliably preventing the formation of tire marks.

[0030] Example 2

[0031] Based on Embodiment 1, this embodiment provides a solution that facilitates overall relocation. The four independent support members 2 are fixedly mounted on a lightweight connecting plate 4 via their bases 22. An RFID mounting structure 3 is provided on the connecting plate 4. The connecting plate 4 provides integrity, facilitating relocation and management; the RFID mounting structure 3 assigns a unique digital identity to each pallet, facilitating full lifecycle tracking and management in intelligent manufacturing systems. The above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Those skilled in the art should understand that several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
