[0053] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0054] After receiving the cigarette box, the present invention restricts the left and right and up and down movements of the cigarette box by the box clamping assembly, the outer swing cover opening assembly opens the outer swing cover of the cigarette box and restricts the forward and backward movement of the cigarette box, and the inner swing cover opening assembly is driven by the box clamping assembly, positioned at the inner swing cover of the cigarette box and opens the inner swing cover, and then the cigarette pushing element in the cigarette pushing assembly adjusts its size, is driven by the cigarette pushing telescopic part, extends into the cigarette box from one end, and pushes the cigarette out of the other end of the cigarette box.

[0055] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0056] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0057] Figures 1 to 10 A special-shaped cigarette box opening and material taking mechanism according to an embodiment of the present invention comprises:

[0058] The mounting bracket 1 includes a lifting driving member 11 and a lifting sliding pair 12. The clamping box assembly 2 is arranged on a slider of the lifting sliding pair 12. The lifting driving member 11 drives the clamping box assembly 2 to slide up and down along the slide rail of the lifting sliding pair 12.

[0059] Specifically, the lifting drive member 11 includes a lifting motor 111 and a lifting rack 112. The lifting motor 111 is arranged on the box clamping assembly 2, and the lifting rack 112 is arranged on the mounting bracket 1. The rotating end of the lifting motor 111 is provided with a second gear matched with the lifting rack 112. When the lifting motor 111 is running, the second gear moves along the lifting rack 112 to drive the box clamping assembly 2 to move. The lifting motor 111 drives the lifting rack 112 to run. When the specifications of the special-shaped cigarette boxes are inconsistent, it is convenient to redesign the transmission to adjust the action range of the structure, so that the present structure can be applied to special-shaped cigarette boxes of various specifications.

[0060] The clamping box assembly 2 comprises a clamping frame 21, a clamping driving member 22 and a clamping claw element group 23; the clamping driving member 22 is arranged on the clamping frame 21, and the movable end of the clamping driving member 22 drives the clamping claw element group 23 to open and close the cigarette box;

[0061] The clamping jaw element group 23 is composed of a rotationally symmetrical clamping jaw sliding pair 231, a clamping jaw driving rack 232 and a clamping plate 233;

[0062] The slide rail of the clamping jaw sliding pair 231 is fixed on the clamping frame 21, the slider of the clamping jaw sliding pair 231 is provided with a clamping plate 233, the clamping plate 233 is provided with a clamping jaw driving rack 232, the clamping jaw driving member is arranged on the clamping frame 21, and the movable end of the clamping jaw driving member 22 is provided with a first gear 221 that cooperates with the clamping jaw driving rack 232. When the clamping jaw driving member 22 moves, it drives the first gear 221 to rotate, thereby driving the clamping jaw driving rack 232 to move, and driving the clamping plate 233 to move.

[0063] The linear guide connection method ensures the performance of the linear guide and makes the installation level of the clamping element group 23 more reasonable and convenient for leveling.

[0064] Optionally, the lifting motor 111 is a servo motor. The overall movement detection of the structure is completed by the current feedback of the servo motor. When the descending action or the grabbing action of the special-shaped cigarette box clamp contacts the box body, the box body generates additional resistance feedback to increase the current of the servo motor, thereby judging the completion status of the action, reducing the use of sensors on the moving parts.

[0065] Optionally, the clamping frame 21 includes a frame vertical plate, a frame horizontal plate and a frame connecting plate; the frame connecting plate fixes the frame vertical plate and the frame horizontal plate vertically to each other; the lifting drive member 11 is fixed to the frame vertical plate; and the clamping box assembly 2 is arranged on the frame horizontal plate.

[0066] The outer swing cover opening assembly includes a box pushing element, a first movable frame and an outer swing cover opening element. The box pushing element abuts against the cigarette box 9. The first movable frame drives the outer swing cover opening element to move downward to open and fix one side of the outer swing cover, and then drives the outer swing cover opening element to move upward to open and fix the other side of the outer swing cover.

[0067] The rotation and opening directions of the outer and inner flaps of the cigarette box 9 are perpendicular to the inner flap, and the outer flap is on the outside and is larger in size, so a special structure is required to open the outer flap. When the cigarette box 9 is on the transmission line, the outer flap is rotated with the help of equipment until it is parallel to the ground, and then the tapes on the outer flaps at both ends are cut open. At this time, the outer flap will naturally flip outward at an angle, providing conditions for the subsequent opening of the outer flap.

[0068] Specifically, the pushing box element includes a telescopic pushing box element and a pushing box flap. The pushing box flap is rotatably arranged at the telescopic end of the pushing box telescopic pushing box element. The pushing box flap is provided with a suction cup, which can adsorb the outer swing cover on the opposite side of the outer swing cover opening element. The pushing box flap rotates to drive the outer swing cover to open upward.

[0069] The principle of setting the box pushing element is to bring the outer swing cover of the front end of the cigarette box 9 as close as possible to the outer swing cover opening element, and the suction cup of the box pushing flap can lift the outer swing cover at the upper rear end of the cigarette box 9 upwards to reduce the resistance when the cigarette is pushed out.

[0070] Optionally, the outer swing cover opening element includes an outer swing cover opening plate and an outer swing cover pressure plate. The outer swing cover opening plate slides downward. Since the outer swing cover is already in a state of slightly opening outward after the tape is cut, the outer swing cover opening plate can slide downward and be inserted into the gap between the outer swing covers to push the lower outer swing cover to flip. In order to prevent the lower outer swing cover from rebounding to its original position, the outer swing cover pressure plate moves to press the lower outer swing cover to prevent rebound. The outer swing cover opening plate then slides upward to push the upper outer swing cover to flip. When it is flipped into place, it stops moving to maintain its flipped state.

[0071] After the above actions are completed, the outer flap at the front end of the cigarette box 9 is in a flipped open state, and the upper outer flap at the rear end is also flipped to an angle that will not hinder the ejection of cigarettes. The lower flap at the rear end will naturally flip downward at a certain angle due to gravity, and together with the inner flap at the rear end, it will be pushed open by the cigarettes during the subsequent ejection process.

[0072] The inner swing cover opening assembly 4 is arranged on the clamping claw sliding pair and moves with the clamping plate; it includes an inner swing cover opening and closing driving element 41, and an adaptive inner swing cover opening and closing element 42 arranged at the rotating end of the inner swing cover opening and closing driving element 41;

[0073] The self-adaptive inner swing cover opening and closing element 42 comprises an inner swing cover opening and closing sliding pair 421 and an inner swing cover adsorbing member 422 arranged on a slider of the inner swing cover opening and closing sliding pair 421, and the inner swing cover adsorbing member 422 slides along the rotation tangent direction of the rotating end of the inner swing cover opening and closing driving member;

[0074] The sizes of the inner swing covers are different for different specifications of cigarette boxes 9, but the position of the inner swing cover relative to the cigarette box 9 is fixed. Therefore, the inner swing cover opening assembly 4 can complete the alignment of the inner swing cover after moving with the splint and clamping the cigarette box 9. The inner swing cover opening and closing driving element 41 is actuated to bring the adaptive inner swing cover opening and closing element 42 as a whole close to the inner swing cover. During the process, the inner swing cover adsorption part 422 sucks the inner swing cover tightly, and with the further movement of the inner swing cover opening and closing driving element 41, the inner swing cover is flipped open. The function of the inner swing cover opening and closing sliding pair 421 is to compensate for the difference in movement routes caused by the different axes of the rotation center of the inner swing cover and the rotation center of the inner swing cover opening and closing driving element 41 in the above process, so that the opening process is smooth and unstuck.

[0075] Optionally, the inner swing cover adsorption member 422 includes a mounting rod and a suction cup, and the mounting rod forms a long hole for the suction cup to be fixed. This design facilitates fine-tuning of the structural position during installation.

[0076] The cigarette pushing assembly 5 includes a telescopic cigarette pushing member 51 and a cigarette pushing element 52. The telescopic cigarette pushing member 51 is extended and retracted to drive the cigarette pushing element 52 to push the cigarette. The cigarette pushing element 52 includes a pair of cigarette pushing plates 521 that can move closer to or farther away from each other and a pushing plate driving member. The pushing plate driving member drives the pushing plates to move relative to each other to adapt to the internal space of different cigarette boxes 9.

[0077] The depth of cigarette packs currently on the market can reach nearly 600 mm. To ensure that the internal cigarettes are completely pushed out to the area outside the rear rocker cover, the stroke of the cigarette pusher assembly 5 must be at least more than 900 mm. The common solution will make the length of the cigarette pusher assembly 5 still exceed 500 mm after being folded, occupying more area, and it is also necessary to ensure the speed of the long rod extending, and the structure is relatively complicated.

[0078] Therefore, in some embodiments, the telescopic cigarette pushing member 51 includes a telescopic member base 511, a telescopic member driving member 512, a first telescopic slide 513 and a second telescopic slide 514; the telescopic member base 511 is fixed to the external frame, the first telescopic slide 513 is slidably arranged on the telescopic member base 511, and the second telescopic slide 514 is slidably arranged on the first telescopic slide 513, and the two constitute a synchronous telescopic structure. The telescopic driving member is installed on the telescopic member base 511, drives the first telescopic slide 513 to slide, and then drives the second telescopic slide 514 to slide, and the cigarette pushing element 52 is arranged on the end of the second telescopic slide 514 away from the first telescopic slide 513.

[0079] Since the first telescopic slide 513 and the second telescopic slide 514 can move synchronously, the advantage is that the movement speed of a single component can be reduced and the stability during movement can be improved; the overall length of the cigarette pushing telescopic member 51 after being retracted can be further reduced, thereby reducing the occupation of the working area.

[0080] Specifically, the telescopic member base 511 and the first telescopic slide 513 are connected by a slide rail, a rack is provided at the bottom of the first telescopic slide 513, the telescopic member driving member 512 is a servo motor, a gear is provided at the end of the motor, the gear cooperates with the rack to drive the first telescopic slide 513 to move; the first telescopic slide 513 and the second telescopic slide 514 are also connected to each other by a slide rail.

[0081] The first telescopic slide 513 and the second telescopic slide 514 achieve synchronous movement on the sides through two groups of pulleys: divided into a forward pulley group and a backward pulley group. The forward pulley of the forward pulley group is rotatably arranged on the side of the first telescopic slide 513. The forward pulley is bypassed by a forward transmission belt. One end of the forward transmission belt is hinged on the telescopic member base 511, and the other end is hinged on the second telescopic slide 514. Therefore, when the first telescopic slide 513 slides forward, the forward pulley moves forward together. Since one end of the forward transmission belt surrounding it is hinged on the relatively immovable structure of the telescopic member base 511, the other end moves relatively with the forward pulley, which is manifested as the other end also moving forward. Since the other end is hinged on the second telescopic slide 514, it eventually drives the second telescopic slide 514 to slide forward, and the sliding speed is the same as that of the first telescopic slide 513.

[0082] The backward pulley group includes a backward pulley and a backward transmission belt. The backward pulley is also arranged on the first telescopic slide plate 513, but at the other end away from the forward pulley, one end of the backward transmission belt wrapped around it is hinged on the telescopic member base 511, and the other end is hinged on the second telescopic slide plate 514; the forward transmission belt and the backward transmission belt have the same length, and are hinged at the position of the telescopic member base 511 and are also on the same straight line, and the position of the second telescopic slide plate 514 is also on the same straight line, and the front and rear straight lines are relatively parallel; the difference between the backward pulley and the forward pulley is that the two pulleys are respectively located on both sides of the straight line formed by the transmission chain being hinged at the telescopic member base 511.

[0083] Optionally, a sliding pair is provided between the cigarette pushing plates 521, and the cigarette pushing driving member 522 is fixed to one cigarette pushing plate 521. A gear is provided at the rotating end of the cigarette pushing driving member 522, and the gear cooperates with a rack provided on the other cigarette pushing plate 521. The rotation of the gear drives the rack to move relative to each other, thereby causing the two cigarette pushing plates 521 to move relative to each other.
