Description

Technical Field

[0001] The utility model relates to the technical field of cigarette production, and in particular, to a cigarette grabbing manipulator. Background Art

[0002] During the production process of cigarettes, cigarettes need to be transferred to achieve the switching of cigarettes between different workstations. At present, the cigarette transfer process usually relies on robot gripping, and the robot uses negative pressure suction to suck the cigarettes. For example, a Chinese patent document with publication number CN112586801A discloses a visually guided cigarette gripping robot, which discloses a negative pressure air gripper, which is provided with an arc-shaped groove, and an air hole is provided in the arc-shaped groove. The inner cavity is connected to an external air source through an air pipe, and the air hole is connected to the inner cavity. When a negative pressure is formed in the inner cavity, the negative pressure air gripper absorbs the cigarette to be grasped through the air hole. After long-term use, the applicant found that when the external air source is activated, negative pressure is quickly formed in the air hole and the inner cavity, and the position on the cigarette corresponding to the air hole is instantly subjected to a large suction force, so that it is tightly adsorbed on the negative pressure air claw. In this process, the large impact force causes the part of the cigarette that contacts the edge of the air hole to be over-squeezed and produce indentations, resulting in the surface quality of the cigarette after transfer cannot be guaranteed, thereby affecting the product qualification rate. In view of this, it is necessary to improve the structure of the cigarette grasping manipulator to improve the surface quality of the cigarette after grasping. Utility Model Content

DETAILED DESCRIPTION

[0022] Now the utility model is described in detail with reference to the accompanying drawings. This figure is a simplified schematic diagram, which only illustrates the basic structure of the utility model in a schematic manner, so it only shows the components related to the utility model.

[0023] See also Figure 1-Figure 6 The utility model provides a cigarette grabbing robot, including a grabbing part 1, a connecting part 2 and a mounting part 3, wherein the grabbing part 1 and the mounting part 3 are respectively connected to the two opposite sides of the connecting part 2, wherein the grabbing part 1 is used to grab cigarettes under the action of negative pressure, the connecting part 2 is used to be connected to the negative pressure device to perform a vacuum operation on the grabbing part 1, and the mounting part 3 is used to be connected to a driving member so that the robot of the utility model moves under the drive of the driving member, thereby transferring the sucked cigarettes.

[0024] The gripping portion 1 is generally a long rod-shaped structure, and a through groove 11 is provided inside the gripping portion 1 along the length direction of the gripping portion 1, and the through groove 11 passes through the two opposite ends of the gripping portion 1. The bottom of the outer surface of the gripping portion 1 forms an arc surface 12, and the arc surface 12 is adapted to the outer surface of the cigarette to be gripped, so that when the gripping portion 1 sucks the cigarette, the arc surface 12 can fit the outer surface of the cigarette, thereby improving the stability when sucking the cigarette.

[0025] The outer surface of the gripping portion 1 except the arc surface 12 includes a first side wall 13, a second side wall 14, a third side wall 15, a fourth side wall 16 and a fifth side wall 17 which are connected in sequence, wherein the first side wall 13 and the fifth side wall 16 are respectively connected to the two opposite sides of the arc surface 12, and among the first side wall 13, the second side wall 14, the third side wall 15 and the fourth side wall 16, two adjacent side walls are smoothly transitioned and connected.

[0026] As a preferred embodiment, a mounting hole 111 connected to the through groove 11 is provided on the side of the gripping portion 1 away from the connecting portion 2. The aperture of the mounting hole 111 is larger than the aperture of the through groove 11. When in use, a seal, such as a silicone seal plug or a rubber seal plug, is installed in the mounting hole 111 to close one end of the through groove 11. In specific implementation, the seal matches the size of the mounting hole 111, and one end of the seal abuts against the bottom wall of the mounting hole 111. In this way, when the through groove 11 is vacuumed from the other end of the through groove 11, the bottom wall of the mounting hole 111 can limit the seal to prevent the seal from being sucked into the through groove 11 under the action of negative pressure. In addition, during processing, the through groove 11 can be drilled at the end of the gripping portion 1 first, and then the end of the through groove 11 can be expanded to form the mounting hole 111. The processing is convenient, which is conducive to production and can effectively control the production cost.

[0027] In addition, the arc surface 12 is inwardly concave to form a groove 18, which is arranged along the length direction of the gripping part 1. The bottom wall of the groove 18 is provided with a through hole 19, which is connected to the through groove 11. The connecting part 2 is provided with a connecting groove 21, which is connected to one end of the through groove 11. When in use, the connecting groove 21 is connected to the negative pressure device through a pipeline. When the negative pressure device is started, the negative pressure device will perform a vacuum operation on the connecting groove 21. At this time, negative pressure is gradually formed in the groove 18, the through hole 19 and the connecting groove 21, and finally the cigarette is adsorbed on the arc surface 12. In the above-mentioned process of adsorbing cigarettes, the provision of the groove 18 prolongs the time required for the target negative pressure value to be formed in the gripping part 1, so that the cigarette will not be squeezed and adsorbed on the arc surface 12 instantly under the action of negative pressure, but will gradually contact the arc surface 12 at a relatively gentle speed, avoiding the situation where an indentation is left on the surface of the cigarette due to a large adsorption force. At the same time, the relatively small through hole 19 can have a certain hindering effect on the airflow in the groove 18, further preventing the air in the groove 18 from passing through the through hole 19 quickly, and also ensuring that the cigarette is smoothly adsorbed on the curved surface 12, thereby improving the surface quality of the cigarette.

[0028] Furthermore, there are two grooves 18, and each groove 18 is provided with a plurality of through holes 19 along the length direction of the groove 18. The plurality of through holes 19 in each groove 18 are arranged at equal intervals, ensuring that the airflow in the groove 18 flows evenly. At the same time, by providing two grooves 18, the cigarette is adsorbed together, the adsorption stability is improved, and the cigarette is effectively prevented from easily falling off the curved surface 12. In this embodiment, each groove 18 has four through holes 19.

[0029] As a preferred embodiment, the through hole 19 is arranged in the middle of the bottom wall of the groove 18, and arcuate walls 181 are formed on the bottom wall of the groove 18 on both sides opposite to the through hole 19, and the arcuate walls 181 extend to the arcuate surface 12. By providing the arcuate walls 181, it is ensured that the gas on both sides of the groove 18 can flow stably to pass through the through hole 19, so that the cigarette can be adsorbed on the arcuate surface 12 more stably.

[0030] As a preferred embodiment, an angle is formed between the central axis of the through groove 11 and the central axis of the connecting groove 21, so that the through groove 11 and the connecting groove 21 together constitute a bending channel, which can slow down the speed of negative pressure formation and help to further ensure that the cigarette is stably adsorbed.

[0031] Furthermore, one end of the connecting groove 21 away from the through groove 11 passes through the side wall of the mounting portion 3. During processing, a hole can be punched through the side wall of the mounting portion 3 to connect it with the through groove 11, which facilitates processing and improves processing efficiency.

[0032] The mounting portion 3 is a flat plate structure, and the end surface of the mounting portion 3 is perpendicular to the axis of the through slot 11. A plurality of fixing holes 31 are provided on the end surface of the mounting portion 3, and the fixing holes 31 are used to be fixedly connected with the driving member, so as to fix the cigarette grabbing manipulator of the utility model on the driving member. The driving member is a cylinder or a rotating disk driven by a motor to realize linear or deflection movement of the cigarette.

[0033] In this embodiment, the gripping portion 1, the connecting portion 2 and the mounting portion 3 are an integrated structure to facilitate processing and effectively control production costs. In addition, the gripping portion 1, the connecting portion 2 and the mounting portion 3 are made of carbon fiber material, which has good strength and light weight, and can achieve lightweight production while ensuring the structural strength of the manipulator.

[0034] The cigarette grabbing robot of the present invention is provided with a groove 18 on the curved surface 12 for matching with the surface of the cigarette. The groove 18 can prolong the time required for forming a target negative pressure value in the grabbing part 1, so that the cigarette will not be instantly squeezed and adsorbed on the curved surface 12 under the action of negative pressure, but will gradually contact the curved surface 12 at a relatively gentle speed, thereby avoiding the situation where an indentation is left on the cigarette surface due to a large adsorption force, thereby improving the surface quality of the cigarette.

[0035] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without departing from the scope of the utility model through the above description.
