Description

Technical Field

[0001] This utility model relates to the field of tobacco machinery, specifically to a composite clamping device for gripping cigarette auxiliary materials. Background Technology

[0002] Currently, the cigarette auxiliary materials used in cigarette making and packaging machines in tobacco factories include eight types: aluminum foil, cardboard, tipping paper, cigarette paper, small box label paper, carton label paper, small box transparent paper, and carton transparent paper. To achieve precise production and save AGV transport capacity and on-site space, it is usually necessary to combine the quantities and varieties of different auxiliary materials according to production needs and in appropriate proportions. This requires three types of palletizing: single-pair, two-in-one, and four-in-one. Currently, auxiliary material palletizing in tobacco factories is mostly done manually, resulting in high labor intensity, significant material damage, and limited material information transmission, hindering the development of automated and intelligent production in tobacco factories. Therefore, a composite clamping device that can adapt to palletizing multiple auxiliary materials is needed, applied to a robotic arm, to achieve rapid and automated palletizing of auxiliary materials and improve the automation level of tobacco equipment production.

[0003] Utility model patent CN219708418U discloses an automatic auxiliary material dispensing device, including a frame component, a translation arm component, and a gripping device. The translation arm component is slidably connected to the frame component to adjust the lateral position of the auxiliary material. The gripping device is slidably connected to the translation arm component to adjust the vertical position of the auxiliary material. The gripping device includes a lifting arm component and a gripping component, with the gripping component slidably connected to the lifting arm component to adjust the longitudinal position of the auxiliary material. The gripping component includes a claw assembly and a suction cup assembly. The claw assembly is used to extend into the disc-shaped auxiliary material for outward gripping, and the suction cup assembly is used to adsorb the auxiliary material. This utility model can improve the efficiency of auxiliary material dispensing, reduce labor input, and reduce the labor intensity of operators, while also meeting the dispensing needs of auxiliary materials of various specifications and shapes. However, the structure disclosed in this automatic auxiliary material dispensing device, which sets the claw assembly and suction cup assembly coaxially, suffers from stroke limitations and motion interference, and the gripping component and translation arm component cannot be quickly connected and disassembled. Utility Model Content

[0004] In order to expand the applicable scenarios of the clamp, avoid interference between different specifications of material picking components, and improve the installation and disassembly efficiency of the material picking components, the technical solution adopted by this utility model is: a composite clamp device for picking up cigarette auxiliary materials, including a mounting frame, an air expansion shaft and several negative pressure adsorption components.

[0005] The air expansion shaft is disposed on one side of the mounting frame, and a plurality of the negative pressure adsorption components are disposed on the other side of the mounting frame. The axis of the air expansion shaft is perpendicular to the axis of the plurality of negative pressure adsorption components.

[0006] The air shaft is used to grip and transfer reel-type auxiliary materials through its own expansion;

[0007] The negative pressure adsorption component is used to grasp and transfer sheet-like auxiliary materials through negative pressure adsorption.

[0008] Beneficial effects: It can ensure that the air expansion shaft and the negative pressure adsorption component each have a large space for movement, avoiding interference between the two. At the same time, it can also use a set of clamping devices to meet the needs of gripping and transferring reel-type auxiliary materials and sheet-type auxiliary materials.

[0009] Based on the above, the upper surface of the mounting frame is provided with a quick-change clamping sub-plate and a functional connector, which are located on opposite sides of the plurality of negative pressure adsorption components.

[0010] The quick-change sub-disk of the clamp is used to connect to the quick-change female disk of the clamp to achieve a detachable connection; the functional connector is used to transmit power, high-pressure gas, and control signals to the air shaft and several of the negative pressure adsorption components.

[0011] Beneficial effects: It enables rapid locking and unlocking, facilitating fixture replacement and maintenance, thereby improving the installation and disassembly efficiency of the material handling components. The ball bearing mechanism extends during locking, locking the male and female discs; it will not detach even when the power and air supply are cut off, ensuring safety.

[0012] Based on the above, the quick-change jig is an annular quick-change jig, and the functional connector is located on the inner side of the annular quick-change jig.

[0013] Beneficial effect: It can protect the functional joint by using the quick-change sub-plate of the clamp, and avoid damage during rotation.

[0014] Based on the above, the negative pressure adsorption assembly includes a negative pressure generator, several negative pressure suction cups, and several hollow elastic connecting rods;

[0015] The negative pressure generator is located on the outside of the mounting frame, and the negative pressure suction cup is flexibly connected to the mounting frame through the hollow elastic connecting rod. The hollow elastic connecting rod is connected to the negative pressure generator through a pipe.

[0016] Beneficial effects: It can be pressed down and produce a certain degree of elasticity when performing negative pressure adsorption.

[0017] Based on the above, the negative pressure suction cups are divided into at least two rows, and the multiple negative pressure suction cups in each row are arranged at equal intervals.

[0018] Beneficial effects: By arranging multiple negative pressure suction cups at equal intervals, the stability during negative pressure adsorption can be improved, and the auxiliary materials can be prevented from falling off.

[0019] Based on the above, the length of the air shaft is greater than the length of the hollow elastic connecting rod.

[0020] Beneficial effect: It can further increase the distance between the air expansion shaft and the negative pressure adsorption component, avoiding interference between the two.

[0021] Based on the above, the mounting frame is a cuboid mounting frame, and the interior of the cuboid mounting frame is provided with a plurality of quick-connect joints for connecting the hollow elastic connecting rods.

[0022] This utility model has substantial features and progress compared with the prior art. Specifically, this utility model provides a composite clamping device for gripping cigarette auxiliary materials. This composite clamping device installs the air expansion shaft and the negative pressure adsorption component separately, so that the axis of the air expansion shaft and the axis of the negative pressure adsorption component are perpendicular to each other. This ensures that the air expansion shaft and the negative pressure adsorption component each have a large movement space and avoids interference between the two.

[0023] Furthermore, the quick-change female gripper is connected to the end effector of the robotic arm via a quick-change female gripper. The quick-change female and male grippers use a pneumatic ball-operated locking system for rapid locking and unlocking, facilitating gripper replacement and maintenance, thereby improving the efficiency of material handling assembly installation and disassembly. The ball-operated mechanism extends when locked, securing the female and male grippers; they will not detach even when the power or air supply is cut off, ensuring safety.

[0024] Furthermore, the power supply, high-pressure gas, and control signals of this composite clamp device are connected through functional connectors between the mother and daughter panels, facilitating installation and maintenance. Attached Figure Description
