[0002] In the current process of shoe production, there are workstations such as gluing, laminating, screwing, and stitching. After development, there are already automated production lines. However, there are a wide variety of shoe types and specifications, and the automated lines have great limitations. For the production of small batches of shoes, their periodicity and economy cannot meet the requirements. Generally, the entire production process of small batches of shoe products is carried out manually, with high labor intensity, easy to cause uneven batch quality, and low production efficiency. Summary of the Invention

Embodiment

[0016] Referring to Figure 1 and Figure 2, this embodiment is a general-purpose automated equipment for shoe manufacturing, including a double-station jig A, a veneering mechanism B, and a screw-driving mechanism C. An installation frame 1 is provided on the machine frame. The veneering mechanism and the screw-driving mechanism are respectively fixed on the installation frame through a veneering mechanism mounting seat 10 and a screw-driving mechanism mounting seat 15. The double-station jig is used to exchange products 3 between different stations, enabling the flow of the jig in an up-and-down alternating manner for the veneering station and the screw-driving station. A shoe last is placed on the jig of the double-station jig as a tool for shaping the upper. The veneering mechanism automatically presses and fits the upper onto the sole. The screw-driving mechanism is used to lock plastic screws into the sole to lock the upper onto the sole.

[0017] Refer to Figure 3 and Figure 4 , the veneering mechanism is provided with a lifting frame. The lifting frame moves up and down along a slide rail 9 through an up-and-down cylinder 4. The pressing block 7 arranged on the upper side of the lifting frame is controlled by a pressing cylinder 6 to act. The pressing edge block 8 arranged inside the lifting frame is controlled by a left pressing cylinder 51 and a right pressing cylinder 52 to act. When the lifting frame reaches the position, each pressing cylinder acts to press and hold the product with a shoe last by the pressing block and the pressing edge block for veneering.

[0018] Refer to Figure 5 , the screw-driving mechanism is controlled to lift and lower by a lifting cylinder 11. After descending to the position, the screw-driving cylinder 12 drives the screw nozzle 14 to reach the position where the product needs to be screwed. Subsequently, the screwdriver 13 locks the plastic screw into the sole to lock the upper onto the sole. The screw-driving mechanism is provided with four screwdrivers, two in the front and two in the back, to lock a pair of screws on the front and back of the product respectively.

[0019] In this utility model, the veneering mechanism uses a cylinder as the pressing power and a shoe last as the shaping tool for the shoe product. With the positioning of the jig, the shoe product is shaped and fitted in the up-and-down and left-right directions. Sensors can be set on the jig as a protection mechanism for each mechanism to reduce the idle operation of the equipment. After the product is coated with glue, a worker places a shoe last as a shaping tool and places it on the jig. The sensor senses whether a product is placed, and the veneering mechanism and the screw-driving mechanism then determine whether to start working.

[0020] In this utility model, after the start switch is turned on, the up-and-down cylinder drives the left pressing cylinder, right pressing cylinder, pressing cylinder, pressing block, and pressing edge block installed on the slide rail to descend. After reaching the position, the left pressing cylinder, right pressing cylinder, and pressing cylinder act to drive the pressing block and the pressing edge block to press and hold the product with a shoe last respectively, achieving the veneering action.

[0021] In this utility model, while the veneering mechanism is acting, the lifting cylinder drives the screw-driving mechanism to descend. After reaching the position, the screw-driving cylinder drives the screw nozzle to reach the position where the screw needs to be driven. Subsequently, the four screwdrivers start to lock the plastic screws onto the sole.

[0022] Finally, the fixture exchanges positions on the double-station fixture. An operator removes the product with the shoe last, takes off the shoe last and collects it, then replaces it with a new semi-finished product with a shoe last installed. The equipment is restarted to enter the next working cycle.

[0023] For this utility model, a detection component can be set up. Through the torque feedback of the screwdriver, it can detect whether the screw is tightened or skewed. The plastic screw feeding adopts a stepped screw aligner. When the double-station fixture changes stations, it screens and arranges qualified screws, cooperates with a fiber optic sensor to detect the arrival of plastic screws, and uses the blowing method to send the plastic screws to the screw nozzle.

[0024] For this utility model, the corresponding actions and residence times of each mechanism are set by programming the control system to achieve automatic veneering and screwing in shoe manufacturing, greatly saving labor costs and reducing the intensity of manual labor. By replacing different fixtures, it can realize the automatic production of different types and specifications of shoe products. Also, the screwing mechanism can be replaced with other ways of fastening the sole and upper, such as stitching, to expand the versatility of this equipment in the shoe manufacturing industry.
