Description

Technical Field

[0001] The utility model relates to the technical field of shoemaking machinery, in particular to an automatic sole glue spraying machine used for glue spraying production of soles. Background Art

[0002] The gluing of soles is a key process in the shoe production process that requires a lot of labor and is time-consuming. It is related to the bonding firmness of the soles and is closely related to the production quality of the shoes. The existing sole glue spraying machines used for the glue spraying production of the soles have low production efficiency. How to improve the production speed is an urgent technical problem to be solved. In addition, since the shoes are transported upside down during the glue spraying process, the glue is easy to flow down to other parts of the upper, and the glue spraying quality is poor, which not only wastes glue but also pollutes the upper. Summary of the invention

[0003] In view of the deficiencies in the prior art, the utility model aims to provide a wall-type sole pressing machine which is used for automatic glue spraying of soles in the shoemaking process, ensures the glue spraying quality and improves the working speed.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] The automatic sole glue spraying machine is characterized in that it includes a loading station, a glue spraying station and a unloading station arranged front to back, a manipulator performs a longitudinal sliding motion to pass through the loading station, the glue spraying station and the unloading station, the manipulator can move up and down and is installed on a longitudinal slide, the up and down movement of the manipulator is driven by a first driving member, and the longitudinal slide is driven by a second driving member to perform a longitudinal sliding motion, the glue spraying station is provided with a glue spraying component, a three-dimensional scanning channel is provided between the loading station and the glue spraying station, a three-dimensional scanner is provided around the three-dimensional scanning channel, and the glue spraying component includes a glue spraying head, and the glue spraying head can perform lowering and raising, horizontal rotation and horizontal sliding movements.

[0006] There are two groups of loading stations and unloading stations side by side on the left and right, and there are two groups of corresponding manipulators on the left and right, and the three-dimensional scanning channel can move left and right.

[0007] Corresponding to the left and right loading stations, there are two groups of left and right feeding conveyor belts, and the two groups of feeding conveyor belts are independently driven by respective motors.

[0008] The three-dimensional scanning channel is a U-shaped channel, and the three-dimensional scanner is provided with three groups, which are respectively installed on the left, right and bottom of the U-shaped channel.

[0009] The glue spray head can swing up and down and is connected to the rotating seat. The up and down swing of the glue spray head is driven by the third driving member. The rotating seat can rotate circumferentially and is arranged on the transverse slide seat. The circumferential rotation of the rotating seat is driven by the third driving member. The transverse slide seat is driven by the fifth driving member to perform a transverse sliding action.

[0010] A glue baffle is arranged above the glue spraying head.

[0011] The glue baffle can be extended and retracted, and a sensor probe is provided to sense the extended and retracted position of the glue baffle.

[0012] After adopting the above technical scheme, when the shoes are sent to the loading station in an upright posture, the robot will grab the shoe last head of the shoe, then the robot moves up, and the longitudinal slide moves backward. When the shoes pass through the three-dimensional scanning channel, three groups of three-dimensional scanners simultaneously perform three-dimensional scanning on the two sides and the bottom surface of the sole in three directions, and record the scanned contour curve data and transmit it to the PLC. Next, the shoes arrive at the glue spraying station. At this time, the glue spraying head lowers its head, rotates horizontally and slides horizontally according to the information sent by the PLC after calculation, and sprays glue accurately onto the sole. Since the shoes are not in an inverted state at this time, the glue is prevented from flowing down to other parts of the shoe surface; when the sole is sprayed with glue, the shoes are sent to the unloading station. At this time, the robot releases the shoes, and then the robot returns to the loading station to grab new unsprayed shoes, and repeats the above actions to complete the automatic glue spraying production of the sole. In the above process, firstly, three groups of three-dimensional scanners simultaneously perform three-dimensional scanning on both sides and three directions of the bottom surface of the sole, which can greatly improve the scanning speed, so that the shoes do not stop during the scanning process, but are continuously transported, thereby improving the production speed of the sole spray glue; secondly, since there are two groups of loading stations and unloading stations arranged side by side on the left and right, and the corresponding manipulators are also arranged on the left and right, the double stations can be used to alternately spray glue on the soles with the left and right movement of the three-dimensional scanning channel, so as to further improve the production speed. In addition, after adopting the above technical solution, due to the setting of the glue baffle, the glue sprayed by the glue spray head can be prevented from splashing upward onto the upper of the shoe above the sole spray glue part, thereby avoiding contamination of the upper and ensuring the quality of the glue spray; at the same time, the retractable setting of the glue baffle ensures that there is a suitable distance between the glue spray head and the periphery of the sole during the glue spraying operation, thereby improving the quality of the glue spraying and avoiding collision between the two, thereby ensuring production safety.
