[0025] Compared with the prior art, the present invention sends a correction instruction by the PLC control system. After the solenoid valve receives the instruction and is energized, the slide cylinder drives the correction device to move forward. When the two fingers of the correction device approach the edge of the sole storage bin, the two fingers controlled by one of the two wedge blocks (the wedge angle is larger) move forward and gradually close to the center line position in the width direction of the sole. The two fingers gradually approach the part of the heel of the sole close to the waist of the sole.

It is adjusted so that the sole is directly above the assembly line and the longitudinal center line of the sole is perpendicular to the moving direction of the belt. The finger cylinder drives the clamp to open and close the sole and release the sole. The lifting cylinder rotates at a small angle, and the rotation angle is adjustable within the range of 0-11° to prevent the front end of the sole from touching the correction device when the swing cylinder rotates. When the swing cylinder moves to the release position of the sole on the slide, it carries the sole and swings to the top of the assembly line belt that automatically sprays the sole treatment agent and the first and second layers of glue, and then releases the sole. The sole falls naturally onto the belt by gravity, and the belt drives the sole to enter the sole robot spray treatment agent process and subsequent processes. Each step of the sole clamping device is controlled by the PLC sequence, which solves the problem that the traditional method of selecting soles is manual selection, which is time-consuming and labor-intensive, prone to errors, and requires payment of labor wages and insurance costs, which is not conducive to reducing costs and industrial upgrading.

[0027] The present invention can realize process or remote automatic control, and the air pressure is adjustable, and the bidirectional speed of the switch is adjustable. If a swing cylinder with a damping device is used, the rotation speed of the revolving door gradually slows down when it approaches the limit position to avoid collision. After the revolving door is closed, the door lock pin is inserted into the pin hole of the door to lock the revolving door. When the revolving door is opened, the door lock pin is first pulled out of the pin hole, and then the revolving door is rotated to open. The revolving door is installed by hanging, and the entire weight is borne by the plane bearing or the radial thrust bearing or the angular contact bearing on the upper bearing seat. The circumferential positioning is borne by the radial ball bearing on the bearing seat. The lower door frame of the revolving door is supported on four rolling fulcrums that are evenly distributed on the circumference and installed on the frame. The revolving door rotates smoothly and lightly. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] The outer side surfaces of the other ends of the two pawls opposite to the swinging ends gradually tilt toward the middle to form a wedge shape;

[0050] The slider for maintaining the clamping force is a linear bearing 27 as a slider set at both ends of the optical axis 26, and the linear bearing 27 maintains the clamping force through a tension spring 28;

[0051] The clamp finger 12 is fixed on the linear bearing 27, and the linear bearing 27 abuts against the outside of the pawl and the outside of the wedge-shaped guide block through the roller 30 fixed on the linear bearing 27;

[0052] The optical axis 26 is fixed on the slide of the slide cylinder 29 through the bracket 31 , the slide cylinder 29 is fixed on the mounting base plate 9 , the pawl is connected to the mounting base plate 9 , and the wedge-shaped guide block is fixed on the mounting base plate 9 .

[0053] The swing lifting device is a base of a clamp swing cylinder 32 connected to a slide table of a magnetically coupled rodless cylinder 10, a swing shaft of the clamp swing cylinder 32 is connected to a rotating table 33, one end of the rotating table 33 is hinged to a swing plate 34, a clamp lifting cylinder 35 is connected to the swing plate 34, a piston head of the clamp lifting cylinder 35 is against the rotating table 33, and one end of the swing plate 34 away from the clamp lifting cylinder 35 is connected to the clamping cylinder 11;

[0054] The rotating platform 33 is provided with a lifting and lowering adjustment screw 36 which is opposite to the piston head of the clamp lifting cylinder 35 at one end thereof close to the clamp lifting cylinder 35 .

[0055] The swing lifting device is a magnetically coupled rodless cylinder 10 whose slide table is connected to the base of the clamp lifting cylinder 35 , the piston head of the clamp lifting cylinder 35 is connected to the clamp swing cylinder 32 , and the swing axis of the clamp swing cylinder 32 is connected to the clamping cylinder 11 .

[0056] A sensor 41 is disposed at the bottom of the clamping cylinder 11 to sense whether the shoe sole is clamped.

[0057] A sensor 39 for sensing the stroke of the slider of the slide cylinder 29 is set on the mounting base plate 9, and the servo motor of the screw module 1, the large torque swing cylinder 3, the clamping cylinder 11, the servo rotation drive device 6, the layer infrared rangefinder 23, the position infrared rangefinder 24, the slide cylinder 29, the swing cylinder 32, the clamp lifting cylinder 35 and the sensor 39 are connected to the PLC.

[0058] The working process of the present invention is as follows: after the storage compartment 8 is filled with soles, the servo rotary drive device 6 is started, the servo rotary drive device 6 drives the cylindrical frame 7 to rotate, the layer infrared rangefinder 23 scans the soles, and the scanning results are stored in the PLC. Each time a sole is clamped, the PLC will subtract the sole at that position, and the value displayed on the touch screen is 0, and the color of the rectangular grid is displayed from red to white; when the layer infrared rangefinder 23 scans incorrectly, there is a sole at a certain position on a certain layer and the layer red is scanned, the layer red is scanned, and the layer red is scanned. If the external rangefinder 23 fails to sense, the system will regard that there is no sole at this position on this layer, and the sole will be left at the end; when the layer infrared rangefinder 23 fails to scan, there is no sole at a certain position on a certain layer, but the layer infrared rangefinder 23 senses that there is a sole during scanning, and the subsequent sole clamping device clamps empty soles when clamping, and the sensor at the rear of the clamp cannot sense the existence of soles. The PLC will issue an instruction to clamp the same size sole again. When it is empty again, the PLC will issue an alarm model to notify the production line patrol personnel to take emergency measures to restore the workstation to normal;

[0059] When it is necessary to open the door, press the door opening touch button on the touch screen display, then the solenoid valve of the lock pin cylinder 19 is energized, then the lock pin cylinder 19 is actuated, the positioning pin 20 is pulled out from the pin hole on the lower door frame 17, then the solenoid valve of the large torque swing cylinder 3 is energized, then the large torque swing cylinder 3 is actuated, and the large torque swing cylinder 3 drives the arc-shaped revolving door 5 to rotate around the revolving door shaft (the revolving door shaft only plays a guiding role), when one of the limit position sensors 18 senses that the arc-shaped revolving door 5 has reached the door opening limit position, the arc-shaped revolving door 5 slowly stops under the action of the damper of the large torque swing cylinder 3, and the door opening action is completed; when it is necessary to close the door, press the button on the touch screen display. Press the door closing touch button, and then the solenoid valve of the large torque swing cylinder 3 loses power, and then the large torque swing cylinder 3 acts, and the large torque swing cylinder 3 drives the arc-shaped revolving door 5 to rotate in the opposite direction around the revolving door shaft (the revolving door shaft only plays a guiding role). When another limit position sensor 18 senses that the arc-shaped revolving door 5 has reached the door closing limit position, the arc-shaped revolving door 5 slowly stops under the action of another damper of the large torque swing cylinder 3. After the arc-shaped revolving door 5 is closed in place, the solenoid valve of the lock pin cylinder 19 loses power, and then the lock pin cylinder 19 acts, and the lock pin cylinder 19 drives the positioning pin 20 to enter the pin hole on the lower door frame 17 to lock the arc-shaped revolving door 5, and the door closing action is completed;

[0060] After the door closing action is completed, the PLC sends a sole correction instruction, the solenoid valve is energized, the slide cylinder 29 drives the clamping finger 12 to move forward (to the left in the figure), and the roller 30 moves forward along the straight section of the clamping guide block 13. When the end of the clamping finger 12 is close to the edge of the sole placement grid of the sole storage and preparation device (at this time, the roller 30 begins to enter the oblique segment of the clamping guide block 13), the roller 30 moves forward along the oblique edge of the clamping guide block 13 and at the same time toward the center line of the sole width (at this time, the clamping finger 12 gradually closes). When the end of the clamping finger 12 is at the leftmost position of the oblique segment of the clamping guide block 13, the roller 30 continues to move to the left along the oblique edge of the clamping guide block 13. The roller 30 misses and drives the clamping finger 12 to fall to the leftmost end of the oblique side of the reset guide block 14. The two clamping fingers 12 are simultaneously and rapidly moved toward the sole width under the tension of the tension spring 28. The shoe sole is corrected by the PLC controlling the electromagnetic valve of the slide cylinder 29 to de-energize the electromagnetic valve. The slide cylinder 29 drives the clamping finger 12 to retreat along the oblique edge of the reset guide block 14 (to the right and away from the center line of the sole width in the figure). The roller 30 first contacts the clamping guide block 13 and then pushes the clamping guide block 13 away. The roller 30 continues to move to the right along the oblique edge of the reset guide block 14. The roller 30 passes through the clamping guide block 13. After the clamping guide block 13 is reset, the roller 30 is located on the right side of the straight line segment of the clamping guide block 13. When the slide cylinder 29 retreats to the right limit position, the clamping finger 12 retreats to the rightmost end of the reset guide block 14, waiting for the next cycle movement. At this time, the distance between the two clamping fingers 12 is the largest, making room for the clamp to clamp the sole.

[0061] When the correction device completes the correction action and returns to the right extreme position, the sensor on the correction device senses that the correction action is completed correctly and issues a command to make the actuator perform subsequent actions in sequence: the solenoid valve of the magnetically coupled rodless cylinder 10 is energized, and the magnetically coupled rodless cylinder 10 drives the clamp swing cylinder 32, the clamp lifting cylinder 35, the clamping cylinder 11 and the clamping finger 37 installed on the clamping cylinder 11 on its slide seat to move to the left as a whole. When the slide of the magnetically coupled rodless cylinder 10 moves to the leftmost position, the clamp enters At the shoe sole clamping position, the solenoid valve of the clamp cylinder 11 is energized, the clamp cylinder 11 moves, and the clamping fingers 37 close to clamp the shoe sole. When the sensor 41 senses that the clamping fingers 37 have clamped the shoe sole, the slide of the magnetically coupled rodless cylinder 10 drives the clamp swing cylinder 32, the clamp lifting cylinder 35, the clamping cylinder 11 and the clamping fingers 37 installed on the clamping cylinder 11 to move right as a whole. When the slide of the magnetically coupled rodless cylinder 10 moves to the rightmost position, the solenoid valve of the clamp lifting cylinder 35 is energized, and the clamp lifting cylinder 37 is lifted. 5 Perform lifting action, rotate the sole clockwise by an angle (adjustable 1-11°) to make the sole higher than the correction device to avoid the sole colliding with any parts or objects when the clamp swing cylinder 32 swings the sole in the next step. The clamp swing cylinder 32 swings counterclockwise (from the upper direction and below the clamp swing cylinder 32) to rotate the sole to 50-60mm above the belt conveyor line of the sole spraying line. The starting position of the clamp swing cylinder 32 is adjustable. The correct starting position is the clamp The longitudinal center line is parallel to the moving direction of the slide of the magnetically coupled rodless cylinder 10. The terminal position of the clamp swing cylinder 32 is that the longitudinal center line of the sole is perpendicular to the longitudinal center line of the belt conveyor line of the sole spraying line. The rotation speed of the clamp swing cylinder 32 is adjustable. The solenoid valve of the clamping cylinder 11 loses power, and the clamping cylinder 11 drives the clamping fingers 37 to open and release the sole. The sole falls parallel to the sole spraying line belt in a free fall motion, and the belt moves intermittently to send the sole to the sole spraying position.

[0062] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several changes and improvements can be made without departing from the overall concept of the present invention, which should also be regarded as the scope of protection of the present invention.
