Description

Technical Field

[0001] The invention relates to the technical field of shoe production, in particular to intermittent rotary shoe-making equipment. Background Art

[0002] In the shoe manufacturing industry, soles and uppers are generally produced separately. The uppers usually need to be fixed on the shoe last first, and then the uppers are subsequently processed. Usually, the part of the bottom of the upper that needs to be glued needs to be roughened first to make its surface rough so as to increase the viscosity of the glue of the bonding part. Then, the roughened area of ​​the bottom of the upper is glued, and the sole is glued at the same time. After applying the glue, it is also briefly baked, and then the upper and sole are fixed and pressed together by a pressing machine. However, in the traditional shoemaking process, the roughening station, gluing station, baking station and pressing station are usually separated independently, and the overall footprint of the equipment is large. It is usually necessary to manually carry out material handling and transfer between the stations.

In this way, there is no need for manual material handling and transfer between the various stations, which greatly reduces manual participation and is conducive to improving the overall shoemaking efficiency.

[0028] Specifically, the sole intermittent rotating platform 1 includes a sole base 11 and a sole turntable 12, a rotatable and vertically arranged sole rotating shaft 13 is installed on the sole base 11 through a sole bearing, a sole intermittent driving source 14 is provided on the sole base 11, the sole intermittent driving source 14 is transmission-connected to the lower end of the sole rotating shaft 13 and is used to drive the sole rotating shaft 13 to rotate intermittently, the sole turntable 12 is fixedly installed on the upper end of the sole rotating shaft 13, four pre-pressing openings 121 are evenly arranged on the sole turntable 12 along its circumferential direction, a pre-pressing plate 122 is provided at the upper end of the sole turntable 12 at the pre-pressing opening 121, a placement groove 1223 adapted to the sole is provided at the upper end of the pre-pressing plate 122, the pre-pressing plate 122 is elastically connected to the sole turntable 12, and correspondingly, the sole intermittent driving source 14 is a combination of a servo motor or a reduction motor and an intermittent divider.

[0041] The method for using the intermittent rotary shoe-making equipment of the present invention comprises the following steps:

[0042] Step 1, loading the sole from the sole loading station 31 onto the corresponding pre-pressing plate 122 on the sole intermittent rotating table 1, loading the shoe last 26 with the upper from the upper loading station 41 onto the corresponding connecting shaft 25 on the upper intermittent rotating table 2;

[0043] Step 2, the sole intermittent rotating platform 1 rotates intermittently and drives the sole to pass through the sole glue spraying station 32 and the sole baking station 33 in sequence, and correspondingly, the sole glue spraying manipulator 511 at the sole glue spraying station 32 will drive the sole glue spraying gun 512 to spray glue on the corresponding area of ​​the sole along the set trajectory, and the sole baking device 52 at the sole baking station 33 will bake the glue on the sole to obtain a suitable adhesive viscosity. At the same time, the upper intermittent rotating platform 2 rotates intermittently and drives the upper to pass through the upper roughening station 42, the upper glue spraying station 43, the upper primary baking station 44 and the upper secondary baking station 45 in sequence, and when the upper is intermittently rotated When the movable platform 2 rotates from the upper loading station 41 to the upper roughening station 42, the driving motor 27 can drive the connecting shaft 25 to rotate 180 degrees and make the bottom of the upper face upwards. Correspondingly, the upper roughening manipulator 611 at the upper roughening station 42 can drive the roughening head 612 to roughen the corresponding area of ​​the bottom of the upper along the set trajectory, and the upper glue spraying manipulator 621 at the upper glue spraying station 43 can drive the upper glue spraying gun 622 to spray glue on the roughened part of the bottom of the upper along the set trajectory. The upper baking device 63 at the upper primary baking station 44 and the upper secondary baking station 45 will bake the glue at the bottom of the upper to obtain a suitable adhesive viscosity;

[0044] Step 3, the sole intermittent rotating platform 1 continues to rotate intermittently and drives the glued and baked sole to rotate to the sole pre-pressing station 34, the upper intermittent rotating platform 2 continues to rotate intermittently and drives the glued and baked upper to rotate to the upper pre-pressing station 46, and the driving motor 27 can drive the connecting shaft 25 to rotate 180 degrees and make the bottom end of the upper face downward, at this time, the upper pre-pressing station 46 overlaps with the sole pre-pressing station 34 and makes the upper be located directly above the sole, and then, the lifting hydraulic cylinder 534 drives the lifting seat 532 to rise and makes the top column 5321 push the pre-pressing plate 122 upward to the pre-pressing position, and makes the upper end of the sole abut against the bottom end of the upper, at this time, the three pre-pressing hydraulic cylinders 535 drive the three pre-pressing blocks 533 in turn to apply an upward pressing force to the flexible placement plate 1222 respectively, so that the sole is pre-pressed at the bottom end of the upper;

[0045] Step 4, the upper intermittent rotating table 2 continues to rotate intermittently and drives the upper with the pre-pressed sole to rotate to the finished shoe pressing station 47. At this time, the third main pressing hydraulic cylinder 6441 and the fourth main pressing hydraulic cylinder 6451 simultaneously drive the toe top block 644 and the heel top block 645 to move upward respectively, so that the pressing bottom plate 647 abuts against the bottom end of the sole and slightly presses upward. Then, the first main pressing hydraulic cylinder 6421 drives the shoe last 26 pressing rod to press down, the second main pressing hydraulic cylinder 6431 drives the toe pressing rod 643 to press down, and the fifth main pressing hydraulic cylinder 6461 drives the middle top block 646 to press upward, and at the same time cooperates with the adaptive swing of the connecting shaft 25, thereby facilitating the complete pressing of the pre-pressed upper and the sole;

[0046] Step 5: The upper intermittent rotating platform 2 continues to rotate intermittently and drives the fully pressed sole and upper to rotate to the finished shoe unloading station 48 for unloading.
