Description

Technical Field

[0001] This utility model relates to the field of shoemaking technology, specifically to a flexible module shoemaking production line. Background Technology

[0002] Traditional shoe production lines typically consist of modules arranged sequentially from upstream to downstream, including lasting, lasting, heel counter, marking, marking, transfer, sole cleaning, applying sole treatment agent, applying upper treatment agent, sole glue, upper glue, sole assembly, sole pressing, and last removal. However, in these traditional production lines, the various shoe-making equipment within each module is generally independent, requiring manual handling of materials such as lasts, uppers, and soles between modules. This leads to problems such as untimely material handling, inconvenient operation, and low production efficiency. Furthermore, the irregular arrangement of the various shoe-making equipment easily results in significant waste of space. Utility Model Content

[0003] The technical problem this invention aims to solve is to provide a flexible modular shoe manufacturing production line. This flexible modular shoe manufacturing production line enables more convenient, faster, and more timely material transfer, thereby improving shoe manufacturing efficiency and reducing labor costs. The technical solution adopted is as follows:

[0004] A flexible modular shoe manufacturing production line includes multiple shoe manufacturing equipment, characterized in that: it also includes a series conveying mechanism, which is composed of multiple conveying units arranged sequentially along its conveying direction, with a material placement platform between two adjacent conveying units; each of the shoe manufacturing equipment is arranged sequentially along the conveying direction of the series conveying mechanism, and each material placement platform corresponds to the workstation position of the corresponding shoe manufacturing equipment.

[0005] During operation, staff can be stationed near each shoe-making production equipment to handle the corresponding shoe-making process. The various conveyor units of the series conveyor mechanism are used to move materials such as shoe lasts, uppers, and soles between the different shoe-making production equipment, transferring them to their respective workstations. When a material is transferred to the position corresponding to a workstation on a particular shoe-making production equipment, it leaves the previous conveyor unit and falls onto the corresponding material placement platform, where it pauses. A staff member then places the material from the platform onto the workstation of the shoe-making production equipment. After the shoe-making process is completed on that equipment, the material is placed onto the next conveyor unit, which then transfers it to the workstation of the next shoe-making production equipment. This process allows materials to be transferred to each shoe-making production equipment sequentially to complete each shoe-making process, ultimately finishing the shoe production. This flexible modular shoe production line connects various shoe production equipment in series through a series conveying mechanism, and sequentially conveys materials such as shoe uppers and soles to the material placement platform corresponding to the workstation of each shoe production equipment. This makes the material conveying more convenient, faster, and more timely, thereby improving shoe production efficiency and reducing labor input and labor costs.

[0006] As a preferred embodiment of this utility model, the material placement platform includes a base and multiple flow bars. The base is disposed between two adjacent conveying units, and the flow bars are arranged side by side on the top of the base. Typically, the flow bars gradually slope downwards from front to back along the conveying direction of the adjacent conveying units. During operation, the material falls onto the flow bars of the material placement platform after being conveyed by the preceding conveying unit, and slides along the flow bars towards the following conveying unit to avoid clogging the material subsequently conveyed by the preceding conveying unit.

[0007] As a preferred embodiment of this utility model, guardrails are provided on both sides of the series conveying mechanism. The guardrails can block and limit the material on the series conveying mechanism, preventing it from falling off one side.

Typically, the shoe-making production devices are arranged closely together in sequence along the conveying direction of the series conveying mechanism. During operation, workers can stand on the inner side of the series conveying mechanism, allowing one person to handle multiple shoe-making processes, thus reducing labor costs. This ensures an orderly arrangement of the shoe-making production devices, a compact overall structure, and advantages such as small footprint, strong visual management, and the ability for one person to handle multiple shoe-making processes, thereby saving labor and space requirements.
