Two sets of mechanical grippers 17 and 16 are respectively arranged on two vertical sliding blocks which are positioned on the same side of the pick-and-place device and are respectively matched with the Z-axis vertical sliding guide rails 18 and 20 on the two Z-axis vertical sliding guide rails 18 and 20 at a certain interval. The Z-axis vertical sliding guide rails 18 and 20 are independently controlled by two Z-axis servo motors 22 and 21 respectively to drive two sets of mechanical grippers 17 and 16 on two vertical sliding blocks to ascend and descend.
Please continue to refer to fig. 1. The vertical lifting mechanism consists of two Z-axis vertical sliding guide rails 18 and 20, two Z-axis servo motors 22 and 21 and two vertical sliding blocks matched with the Z-axis vertical sliding guide rails 18 and 20. The positions of the mechanical grippers 17 and 16 on the Z-axis vertical sliding guide rails 18 and 20 can be independently controlled to move up and down through the Z-axis servo motors 22 and 21, so that accurate positioning is realized. The vertical lift mechanism is in the form of an electric cylinder drive, the principle of which can be understood with reference to the prior art.
One gripper 17 is used to transfer and grip the shoes between the transfer line (large belt line) 14 and the stitching station 13, and the other gripper 16 is used to grip the shoes on the equipment belt 15, transfer the shoes between the waiting station 12 and the stitching station 13, and place the shoes on the stitching station 13.
The distance between the two grippers 17 and 16 corresponds to the distance between the transmission line 14 and the equipment belt 15; and also corresponds to the distance between the apparatus belt 15 and the press-fitting station 13, and to the distance between the press-fitting station 13 and the waiting station 12.
The hand grips 17, 16 may be pneumatic grips, but are not limited thereto. The gripper can adopt the existing gripper structure for gripping shoes, and adopts the air cylinder to control the gripper to open and close, and the control principle can be understood by referring to the prior art.
Please refer to fig. 1. The horizontal moving mechanism can be composed of an X-axis horizontal sliding guide rail 19, an X-axis servo motor 23 and a horizontal sliding base 24 which are fixed on the mounting platform 11 of the pressing station 13 and span above the transmission line 14 and the equipment belt 15.
The two Z-axis vertical slide rails 18, 20 are mounted on the same side of a horizontal slide base 24. Two Z-axis servomotors 22, 21 and an X-axis servomotor 23 may be mounted on a horizontal slide base 24 through a mounting plate.
The X-axis horizontal sliding guide 19 may be fixedly disposed above the mounting platform 11 by the bracket 10.
The horizontal moving mechanism is controlled by an X-axis servo motor 23 independently to drive a vertical lifting mechanism on a horizontal sliding base 24 and the mechanical grippers 17 and 16 to move horizontally back and forth. The X-axis servo motor 23 can control the sliding displacement of the sliding base 24 on the X-axis horizontal sliding guide rail 19, thereby realizing the accurate positioning of the mechanical grippers 17, 16 on the vertical lifting mechanism installed on the sliding base 24. The horizontal movement mechanism is in the form of an electric cylinder drive, the drive principle of which can be understood with reference to the prior art.
The pressing station 13 and the waiting station 12 are arranged on the mounting platform 11 in parallel, and the equipment belt 15 and the transmission line 14 are arranged on one side of the pressing station 13 in sequence.
In order to improve the efficiency, the pressing station 13 and the waiting station 12 can be respectively provided with one set on two sides of the X-axis horizontal sliding guide rail 19. Correspondingly, the vertical lifting mechanism and the grabbing mechanism connected with the vertical lifting mechanism can also be respectively provided with one set at two sides of the X-axis horizontal sliding guide rail 19. At this time, each of the Z-axis servomotors 22 and 21 can be used to simultaneously control the vertical sliders on the corresponding Z-axis vertical sliding guides 18 and 20 on both sides to move synchronously. Each Z-axis servo motor 22, 21 can realize synchronous control of the vertical sliding blocks on the Z-axis vertical sliding guide rails 18, 20 on two sides through a shaft coupler.
As the utility model relates to a typical shoe taking and placing action execution control method, the following steps can be carried out:
a. a gripper 16 is driven by a Z-axis servo motor 21 to descend, first grip the unfinished shoe from the previous station on the equipment belt 15 and lift it to a predetermined height.
b. The horizontal sliding base 24 is driven by the X-axis servo motor 23 to translate rightward until the gripper 16 reaches the standby station 12.
c. The gripper 17 is driven by a Z-axis servo motor 22 to descend, grip the pressed shoes on the pressing station 13 and lift to a preset height position.
d. The horizontal sliding base 24 is driven by the X-axis servo motor 23 to move leftwards, so that the gripper 16 moves to a position above the pressing station 13. At this time, the Z-axis servomotor 21 drives the gripper 16 to descend, and places the unfixed shoe onto the stitching station 13, and then lifts it to a predetermined height position.
The e.X axis servo motor 23 drives the horizontal sliding base 24 to move left, the grip 17 is above the transmission line (large belt line) 14, the Z axis servo motor 22 drives the grip 17 to descend, and the pressed shoes are placed on the large belt line.
The f.Z axis servo motor 21 drives the gripper 16 to descend, grip the unfinished shoe on the equipment belt 15, and lift to a predetermined height. And e, circularly executing the steps a to e, and continuously carrying out the operation of taking and placing the shoes.
Through the above-mentioned synergistic action of two independent control's of snatching mechanism mechanical tongs, vertical lift mechanism, horizontal migration mechanism, cyclic execution snatchs and transport action periodically, makes the utility model discloses a get and put the device and can accomplish in 5s and tak away the shoes that the pressfitting is good away, place the assigned position, snatch new uncompleted shoes again to operating position, finally realize the high coincidence of pressfitting action and transport action, improved production facility's beat greatly.
What has just been said is the preferred embodiment of the present invention, the embodiment is not used for limiting the patent protection scope of the present invention, therefore all the equivalent structural changes made by the contents of the description and the drawings of the present invention should be included in the protection scope of the present invention.
