Technical Field

[0001] The utility model relates to the field of stamping automation, in particular to a shuttle device capable of gravity centering. Background Art

[0002] Domestic stamping production lines can be divided into the destacking and transportation part at the beginning of the line, the stamping part in the middle of the line, and the transportation part at the end of the line. Among them, the indispensable part of the transportation part at the beginning of the line is the centering and transportation of the sheet metal.

[0003] Belt conveyors and shuttle mechanisms are often used to transport sheet materials, and mechanical centering devices and visual centering are often used by robots to position and grab sheet materials. These two functions work together to realize the process of transporting sheet materials from the front of the stamping line to the stamping part in the line, and then the robot grabs and loads the materials. However, this existing combination mode has the disadvantages of requiring a lot of equipment and high cost.

[0004] Therefore, it is necessary to invent a shuttle device that can be gravity-centered. Utility Model Content

[0023] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0024] Please refer to the attached Figure 1-6 The utility model provides a gravity-centered shuttle device, comprising a fixed base 1, with linear guide rails 2 symmetrically fixed to both sides of the top of the fixed base 1, a mobile frame 3 connected to the top of the fixed base 1 through a driving component, and both sides of the bottom of the mobile frame 3 are slidably connected to the surfaces of the two linear guide rails 2, the top of the mobile frame 3 is connected to a table 4 through a gravity centering component, and a material rack interface 5 is fixed to the top of the table 4;

[0025] The driving assembly includes a servo motor 6, which is fixedly mounted on one end of the top of the fixed base 1. The output shaft of the servo motor 6 is fixed with a transmission pulley 7. The other end of the top of the fixed base 1 is rotatably connected to a driven pulley 8. The transmission pulley 7 and the driven pulley 8 are connected through an open synchronous belt 9. The open ends of the open synchronous belt 9 are fixed with connecting plates 10, and the connecting plates 10 are fixed to the bottom of the mobile frame 3. Specifically, when the servo motor 6 is running, it can drive the open synchronous belt 9 to rotate forward and reverse between the transmission pulley 7 and the driven pulley 8, thereby driving the connecting plate 10 to move back and forth in a straight line, which can drive the mobile frame 3 sliding on the surface of the linear guide rail 2 to move back and forth synchronously in a straight line, so that the table 4 can be accurately moved into place according to production needs. Moreover, the servo motor 6 is installed on the fixed base 1 and does not move with the table 4, avoiding the situation where the motor cable needs to pass through the drag chain, simplifying the cable path, and ensuring the stability of the transmission system.

[0026] The gravity centering component includes a horizontal limit bracket 11, the bottom end of the horizontal limit bracket 11 is vertically fixed to one end of the top of the mobile frame 3, and a first anti-collision block 12 is horizontally fixed to the top of the horizontal limit bracket 11. A first proximity switch 13 is fixed to the end of the first anti-collision block 12. The proximity switch is a technology well known to those skilled in the art. The first proximity switch 13 is horizontally located below one end of the table 4. A tilt limit bracket 14 is vertically fixed to the other end of the top of the mobile frame 3. A second anti-collision block 15 is tiltedly fixed to the top of the tilt limit bracket 14. A second proximity switch 16 is fixed to the end of the second anti-collision block 15. The second proximity switch 16 is tilted below the other end of the table 4. Support columns 17 are vertically fixed at any two diagonal points on the top of the mobile frame 3. A first fisheye joint 18 is fixed to the top of the support column 17. The top of the first fisheye joint 18 is hinged to the bottom of the table 4. The other end of the top of the mobile frame 3 The two outer diagonal positions are hinged with a cylinder 19, and the top of the output shaft of the cylinder 19 is fixed with a second fisheye joint 20. The top of the second fisheye joint 20 is hinged to the bottom of the table 4. Specifically, the table 4 is supported by a support column 17 and a cylinder 19, and the hinged positions are respectively provided with a first fisheye joint 18 and a second fisheye joint 20, so that the table 4 can rotate diagonally around the center of the table 4. The horizontal limit bracket 11 and the tilt limit bracket 14 can play a certain supporting role on the table 4, and the horizontal limit bracket 11 and the tilt limit bracket 14 are respectively provided with a first proximity switch 13 and a second proximity switch 16, and the first proximity switch 13 and the second proximity switch 16 are respectively protected by a first anti-collision block 12 and a second anti-collision block 15, which can not only protect the proximity switch, but also detect whether the status of the table 4 meets the use requirements. There is no need for visual alignment, which reduces equipment and reduces costs.

[0027] It should be noted that the device is electrically connected to an external main controller and 220V AC power, and the main controller can be used as a control device for a computer or the like. The device also includes an air circuit system, which is connected by an air source component and an air pipe to control the air supply and control of the cylinder. Specifically, each cylinder is controlled by a three-position five-way solenoid valve and a two-position three-way solenoid valve. After the gas is processed by the triplex component, it is sent to the cylinder through the three-position five-way solenoid valve. The lifting and lowering of the cylinder is controlled by the three-position five-way solenoid valve. When it is lifted or lowered to a given position, the two-position three-way solenoid valve controls the cylinder to lock. At this time, the overall angle of the table is fixed. It should be noted that a speed regulating valve is installed at the air inlet of each cylinder, which controls the speed of the piston rod movement by adjusting the compressed air flow at the air inlet.

[0028] The use process of the present invention is as follows: when used as a shuttle device, the cylinder 19 is lifted to a state where the table 4 is parallel to the linear guide rail 2. When in use, the table 4 is driven to adjust its state by the cylinder 19. When the first proximity switch 13 on the horizontal limit bracket 11 detects the table 4, that is, detects whether the state of the table 4 meets the use requirement, the cylinder 19 stops lifting and locking the cylinder 19, and then drives the table 4 to move at both ends of the fixed base 1 to transport materials; and when used as a common shuttle device, the material rack interface can be used in conjunction with the material rack at the production site to accurately move the sheet material from the left end to the right end to achieve the purpose of transporting the sheet material. When used as a gravity centering platform, the mobile frame 3 can be locked at one end of the top of the fixed base 1 (such as Figure 2 As shown), the cylinder 19 under the console table 4 is controlled to operate, so that the table 4 is tilted at a certain angle to achieve the purpose of gravity centering the sheet, which facilitates the switching between the transportation function and the gravity centering function.

[0029] The above description is merely a preferred embodiment of the present invention. Anyone skilled in the art can utilize the above-described technical solutions to modify the present invention or create equivalent technical solutions. Therefore, any simple modification or equivalent replacement based on the technical solutions of the present invention falls within the scope of protection claimed by the present invention.
