DETAILED DESCRIPTION
[0018] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the preferred embodiments are only for illustrating the present invention, rather than for limiting the protection scope of the present invention.
[0019] like Figure 1-3As shown in the figure, a gripper for loading and unloading woven bagged raw tobacco bales has a main body of a baffle 1. The baffle 1 is circumferentially connected to the execution end of a multi-degree-of-freedom robotic arm. In the middle upper part of the baffle 1, there is a bracket 7. The bracket 7 is a frame-shaped structure with an opening facing downwards. The bracket 7 is arranged in the front-back direction. A vertical hydraulic cylinder 6 is fixed on the bracket 7. The push rod 13 of the hydraulic cylinder 6 penetrates through the bracket 7. The bottom of the push rod 13 is rotationally connected to a left connecting rod 12 and a right connecting rod 5 through a rotating shaft 8. On the left and right sides of the bracket 7 on the baffle 1, there are respectively a left support structure and a right support structure. The left support structure is multiple left columns 9 arranged in the front-back direction. The right support structure is multiple right columns 2 arranged in the front-back direction. The upper part of the left support structure is rotationally connected to a left thorn needle frame 10 on its left side through a rotating shaft 8. The left thorn needle frame 10 is in a "day" - shaped structure. The right side of this "day" - shaped structure is connected to each left column 9 through a rotating shaft 8. Multiple arc-shaped left thorn needles 11 that can pierce the woven bag are evenly spaced in the front-back direction below it. The upper part of the right support structure is rotationally connected to a right thorn needle frame 4 on its right side through a rotating shaft 8. The right thorn needle frame 4 is in a "day" - shaped structure. The left side of this "day" - shaped structure is connected to each right column 2 through a rotating shaft 8. Multiple arc-shaped right thorn needles 3 that can pierce the woven bag are evenly spaced in the front-back direction below it. Each left thorn needle 11 and each right thorn needle 3 correspond one by one and their openings face each other. The strength of each left thorn needle 11 and each right thorn needle 3 together can lift the raw tobacco bale. On the baffle 1, thorn needle perforations corresponding to each left thorn needle 11 and right thorn needle 3 are provided. The free ends of the left connecting rod 12 and the right connecting rod 5 are respectively rotationally connected to the middle parts of the two "day" - shaped structures. The aforementioned woven bag is a woven bag or a gunny bag.
[0020] The working principle of this gripper is that before grasping the raw tobacco bale, the state of the gripper is as shown in Figure 1 , that is, the tips of each left thorn needle 11 and right thorn needle 3 are inside or above the holes of the baffle 1. When grasping, the baffle 1 is attached to the upper surface of the raw tobacco bale 14. The push rod 13 of the hydraulic cylinder 6 is pushed out, which will drive each right thorn needle 3 and each left thorn needle 11 to pierce into the raw tobacco bale 14 (as shown in Figure 2 and 3 ). After the raw tobacco bale is grasped in place by moving the gripper through the multi-degree-of-freedom robotic arm, the push rod 13 of the hydraulic cylinder 6 is retracted, and then each left thorn needle 11 and each right thorn needle 3 are withdrawn from the raw tobacco bale to put down the raw tobacco bale 14. Using this gripper, the loading and unloading of raw tobacco bales can be fully automated, with high efficiency.
[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the present technical solution, and they should all be covered within the scope of the claims of the present invention.
