Description

Technical Field

[0001] The invention relates to the technical field of textile tools, and more particularly to a mechanism for transferring sliver barrels. Background Art

[0002] The sliver barrel is a type of tool mainly used in the textile field to hold textile fabrics and fiber materials. The sliver barrel is mainly made of high-strength plastic, so it is generally called a plastic sliver barrel or a textile sliver barrel. The bottom is equipped with universal wheels, and the upper edge is sealed with stainless steel. It is widely used in textile workshop production lines.

[0003] Based on the above, the inventors found that: since the sliver barrels need to be transported between various processes, the existing automatic transportation method is to use a traction-type AGV trolley to intelligently transport the sliver barrels, install a telescopic arc clamping device in front of the AGV trolley, and use the universal wheels at the bottom of the sliver barrels to traction and transportation. This method needs to meet the size of the body plus the sliver barrel when transporting sliver barrels, so the space requirement is relatively high. It cannot operate in many narrow alleys and areas with limited AGV path space, and the overall applicability is poor. At the same time, the overall stability of the traction and transportation method is relatively poor. When the transportation path is more complicated, it is easy to be clamped unsteadily, and there will be shaking, rollover and other phenomena, which reduces the efficiency of transportation. Therefore, in view of this, the existing structure is studied and improved, and a mechanism for transporting sliver barrels is provided, in order to achieve a more practical purpose. Summary of the invention

[0004] 1. Technical problems to be solved

At the same time, the coordinated clamping of the gripper and the central clamping mechanism can adapt to sliver barrels of different sizes within a certain range, and the stability is significantly improved.

With the cooperation of the rotating mechanism and the connecting rod assembly, the barrel is placed on the cargo platform for transportation, so that the transportation method is changed from the traditional traction type to the backpack type, so that the barrel no longer occupies space during operation, reducing the demand for the operating space of the AGV body, improving the overall applicability, and greatly improving the transportation efficiency.

A blocking plate is provided under the gripper to ensure that the barrels do not fall. At the same time, with the support of the loading platform, the barrels can be more stable during the transportation process to avoid shaking or tipping. BRIEF DESCRIPTION OF THE DRAWINGS

When in use, the reset spring 306 installed under the loading platform 305 can ensure the safe contact between the barrel and the loading platform 305, and the loading platform 305 can be reset in time after the barrel is removed.

[0052] See also Figure 4 or Figure 5 The central clamping mechanism 7 includes a worm gear reducer 701 fixedly installed on the top of one end of the base 2, a servo motor 702 is installed at one end of the worm gear reducer 701, a top driving shaft of the worm gear reducer 701 is fixedly connected with a rocker arm 703, and a pull rod 704 is rotatably connected between the rocker arm 703 and the corresponding inner wall of the base 6 through a pin shaft. When in use, the servo motor 702 drives the middle rocker arm 703 to rotate through the worm gear reducer 701, and the rocker arm 703 connects to the pull rod 704 to drive the bases 6 on both sides to move toward the middle or both sides at the same time, thereby realizing the clamping and releasing actions.

[0053] See also Figure 7 The rotating mechanism 8 includes a cycloidal pinwheel reducer 801 installed on the inner wall of the base 6, and a servo motor 2 802 is installed at one end of the cycloidal pinwheel reducer 801. The driving shaft at the other end of the cycloidal pinwheel reducer 801 passes through the base 6 and is fixedly connected to a swing arm 803. The end of the swing arm 803 away from the base 6 is rotatably connected to the outer side of the corresponding gripper 9 through a rotating shaft 804. A connecting rod assembly 10 is arranged between the rotating shaft 804 and the upper end position of the outer side of the corresponding base 6. When in use, the servo motor 2 802 drives the swing arm 803 to rotate through the cycloidal pinwheel reducer 801, and the gripper 9 flips with the swing arm 803. The connecting rod assembly 10 ensures that the gripper 9 is always in a vertical state.

[0054] See also Figure 7The connecting rod assembly 10 includes a limit arm 1001 fixed to the outer periphery of the rotating shaft 804, and a connecting rod 1002 is rotatably connected between one end of the limit arm 1001 and the outer upper end position of the corresponding base 6 through a pin shaft.

[0055] See also Figure 6 and Figure 7 The swing arm 803 is arranged in parallel with the corresponding connecting rod 1002.

[0056] See also Figure 6 The two grippers 9 are provided with arc-shaped grooves on the sides close to each other, and the bottoms of the arc-shaped grooves are fixedly connected with blocking plates 11. When in use, the blocking plates 11 provided under the grippers 9 can ensure that the barrels do not fall and ensure the stability of the barrels.

[0057] When in use: when the AGV body 1 runs in front of the barrel, the gripper 9 is lowered from the top of the AGV body 1, and the servo motor 1 702 drives the middle swing arm 703 to rotate through the worm gear reducer 701, and the swing arm 703 connects the pull rod 704 to drive the bases 6 on both sides to move toward the middle at the same time, and uses the two grippers 9 to clamp the barrel, and the gripping force is controlled by the torque of the servo motor 1 702. When the servo motor 1 702 reaches the set torque, it stops automatically to adapt to barrels of different diameters. At this time, the blocking plate 11 set under the gripper 9 can hook the edge of the bottom of the barrel, and then start the servo motor 2 802, and the servo motor 2 802 drives the swing arm 8 through the cycloid pinwheel reducer 801. 03 rotates, and the gripper 9 flips with the swing arm 803. The connecting rod assembly 10 ensures that the gripper 9 is always in a vertical state, and moves the barrel to the loading platform 305 of the AGV body 1. The reset spring 306 installed under the loading platform 305 ensures the safe contact between the barrel and the loading platform 305. When the sensor senses that the gripper 9 is in place, the AGV body 1 starts to transfer the barrel, and the gripper 9 always clamps the barrel. This can not only reduce the running radius of the AGV body 1, but also prevent the barrel from shaking, rolling over, etc. When the AGV body 1 is in place, the gripper 9 is used to place the barrel at the specified position, and the gripper 9 rotates back to the top of the AGV body 1 to continue to take out the next barrel.
