DETAILED DESCRIPTION

[0022] The technical scheme in the embodiment of the utility model will be clearly and completely described in the following by combining the drawings in the embodiment of the utility model, obviously, the described embodiment only is a part of the embodiment of the utility model, instead of all the embodiments. Based on the embodiment in the utility model, all other embodiments obtained by ordinary skilled person in the art without making creative labor belong to the scope of the utility model protection.

[0023] The utility model discloses a cigarette posture correction device to solve the problems existing in the prior art, and the posture of the cigarette is detected by the detection mechanism, and then the posture of the cigarette is adjusted by cooperating with the blowing mechanism and the baffle.

[0024] In order to make the above-mentioned purpose, features and advantages of the utility model more apparent, obvious and understandable, the utility model will be further described in detail below in combination with the drawings and specific embodiments.

[0025] Please refer to as Figs. 1-3 The utility model discloses a cigarette posture correction device, which comprises a detection mechanism for detecting the included angle between the cigarette and the conveying direction of the conveying belt, a blowing mechanism for blowing the end of the cigarette and a baffle 20. The detection mechanism and the blowing mechanism are both arranged in front of the baffle 20 along the conveying direction of the conveying belt, and the blowing mechanism is located on the side of the conveying belt. The blowing direction of the blowing mechanism is parallel to the conveying belt. The baffle 20 switches between the blocking state for blocking the cigarette and the release state for releasing the cigarette through a driving mechanism. The main working principle is as follows: the posture of the cigarette is detected by the detection mechanism. If the posture belongs to a state that cannot be directly scanned, the baffle 20 is used to block the cigarette to realize posture adjustment, or the blowing mechanism and the baffle 20 are used together to realize posture adjustment. In this embodiment, two postures of the cigarette are defined, which are represented by the included angle between the cigarette and the conveying direction of the conveying belt. The first posture is 36°-144°, and the second posture is 0°-36° and 144°-180°. In the two postures, the baffle 20 is needed in the first posture, and the blowing mechanism and the baffle 20 are needed together in the second state.

[0026] The driving mechanism can be a stepping motor 23 or an electric / pneumatic / hydraulic telescopic rod. When the stepping motor 23 is selected, the stepping motor 23 is used to drive the baffle 20 to rotate, so as to switch between the blocking state and the release state. When the telescopic rod is selected, the linear motion of the telescopic rod is used to drive the baffle 20 to move up and down, so as to switch between the blocking state and the release state.

[0027] A limit sensor can be arranged to limit the movement path of the baffle 20. The limit sensor can be a travel switch. When the baffle 20 rotates, travel switches can be arranged on both sides of the rotation path of the baffle 20. When the baffle 20 contacts the travel switch, it means that it is in place. When the baffle 20 moves linearly, a protruding part can be arranged on the baffle 20. Travel switches are arranged on both sides of the movement path of the protruding part. When the protruding part contacts the travel switch, it means that it is in place.

[0028] The detection mechanism can be a camera. The posture of the current cigarette is captured by the camera and transmitted to the control system, so as to control the subsequent movement of the blowing mechanism and the baffle 20.

[0029] The detection mechanism can also be a sensor group comprising a first laser reflection sensor 3 and a second laser reflection sensor 4 arranged in sequence along the conveying direction of the conveying belt, the distance between the rays of the first laser reflection sensor 3 and the second laser reflection sensor 4 and the conveying belt is less than the height of the cigarette, so as to block the rays when the cigarette passes through, so as to be detected by the sensor, the rays of the first laser reflection sensor 3 and the second laser reflection sensor 4 are perpendicular to the conveying direction of the conveying belt, the distance between the rays of the first laser reflection sensor 3 and the second laser reflection sensor 4 is equal to the length of the conveying belt occupied by the cigarette when the angle between the cigarette and the conveying direction of the conveying belt is 36° or 144°, and the length is taken as a critical point, if the rays of the two sensors are blocked at the same time, it represents that the inclination angle of the cigarette is less than 36° or greater than 144°, at this time, the blowing mechanism needs to be blown to adjust, and then the baffle 20 is used for adjustment, if only the ray of the second laser reflection sensor 4 is blocked, it represents that the inclination angle of the cigarette is between 36° and 144°, at this time, only the baffle 20 needs to be adjusted.

[0030] The third laser reflection sensor 5 can be arranged on the side of the first laser reflection sensor 3 away from the second laser reflection sensor 4, and the fourth laser reflection sensor 6 can be arranged on the side of the second laser reflection sensor 4 away from the first laser reflection sensor 3, the rays of the third laser reflection sensor 5 and the fourth laser reflection sensor 6 are perpendicular to the conveying direction of the conveying belt, the distance between the rays of the third laser reflection sensor 5 and the fourth laser reflection sensor 6 and the conveying belt is less than the height of the cigarette, and the distance between the rays of the third laser reflection sensor 5 and the fourth laser reflection sensor 6 is greater than the diagonal length of the cigarette, the third laser reflection sensor 5 and the fourth laser reflection sensor 6 can exclude interference, when neither of them detects the cigarette, the detection of the first laser reflection sensor 3 and the second laser reflection sensor 4 is valid detection, which can prevent the situation that the first laser reflection sensor 3 and the second laser reflection sensor 4 detect the object at the same time, for example, the previous cigarette does not exit the position of the second laser reflection sensor 4, and the next cigarette just arrives at the position of the first laser reflection sensor 3.

[0031] The detection mechanism further comprises a fifth laser beam interrupt sensor 7, which is located behind the fourth laser beam interrupt sensor 6, the rays of the fifth laser beam interrupt sensor 7 are perpendicular to the conveying direction of the conveying belt, the distance between the rays of the fifth laser beam interrupt sensor 7 and the conveying belt is less than the height of the cigarette, the distance between the rays of the fourth laser beam interrupt sensor 6 and the fifth laser beam interrupt sensor 7 is equal to the length of the conveying belt occupied by the cigarette when the angle between the cigarette and the conveying direction of the conveying belt is 70° or 110°, and the length is taken as a critical point, if the rays of the two sensors are blocked at the same time, it represents that the angle of the cigarette is between 36°-70° or 110°-144°, at this time, the baffle 20 needs to be adjusted, if only the fifth laser beam interrupt sensor 7 is blocked, it represents that the angle of the cigarette is between 70° and 110°, at this time, the baffle 20 does not need to be adjusted, that is, the first posture is subdivided again, 36°-70° and 110°-144° are postures that need the intervention of the baffle 20, and the postures of the angle of 70°-110° are divided out, so that the energy required for the movement of the baffle 20 in the postures can be saved, and the efficiency is improved.

[0032] The sixth laser beam interrupt sensor 8 is arranged behind the fifth laser beam interrupt sensor 7, the rays of the sixth laser beam interrupt sensor 8 are perpendicular to the conveying direction of the conveying belt, the distance between the rays of the sixth laser beam interrupt sensor 8 and the conveying belt is less than the height of the cigarette, and the distance between the rays of the second laser beam interrupt sensor 4 and the sixth laser beam interrupt sensor 8 is greater than the length of the conveying belt occupied by the cigarette when the angle between the cigarette and the conveying direction of the conveying belt is 70° or 110°, the cooperation principle of the second laser beam interrupt sensor 4 and the sixth laser beam interrupt sensor 8 is the same as that of the third laser beam interrupt sensor 5 and the fourth laser beam interrupt sensor 6, and both are for excluding interference.

[0033] The detection mechanism further comprises a seventh laser beam interrupt sensor 9, which is located behind the baffle 20, the function of the laser beam interrupt sensor is to detect whether the cigarette has left the baffle 20, when the distance between the rays of the seventh laser beam interrupt sensor 9 and the intercepting position of the baffle 20 is greater than the width of the cigarette, the baffle 20 can fall again to block the next cigarette when the seventh laser beam interrupt sensor 9 detects the cigarette, when the distance between the seventh laser beam interrupt sensor 9 and the intercepting position of the baffle 20 is less than the width of the cigarette, the baffle 20 can fall again to block the next cigarette only after the seventh laser beam interrupt sensor 9 is converted from the state of detecting the cigarette to the state of not detecting the cigarette, so as to avoid the situation that the previous cigarette has not left the intercepting position of the baffle 20 when the baffle 20 blocks the next time, resulting in the situation that the baffle 20 is stuck or the cigarette is damaged.

[0034] In addition, in the case that the baffle 20 is controlled by the stepping motor 23 and the baffle 20 is turned to open towards the direction of the cigarette, the seventh laser reflection sensor 9 can also be designed at a specific position, at which the laser of the seventh laser reflection sensor 9 at the specific position is just below the bottom end of the baffle 20 in the limit release state when the baffle 20 is turned to the limit release state in which the distance between the bottom end of the baffle 20 and the surface of the conveying belt is just enough for the cigarette to pass through.

[0035] The cigarette posture correction device further comprises a guide mechanism, the guide mechanism comprises two guide plates 2, the two guide plates 2 are arranged in parallel, and the detection area of each sensor is between the two guide plates 2; the guide plates 2 are parallel to the conveying direction of the conveying belt; the specific laser reflection sensor is arranged outside the guide plate 2; the guide plate 2 is provided with an opening at the position corresponding to the specific laser reflection sensor; the height of the guide plate 2 is not less than the height of the cigarette; the first laser reflection sensor 3 and the second laser reflection sensor 4 are provided with the first laser diffuse reflection sensor 10, the second laser diffuse reflection sensor 11, the third laser diffuse reflection sensor 12 and the fourth laser diffuse reflection sensor 13 which are all located above the conveying belt; the arrangement direction of the first laser diffuse reflection sensor 10 and the second laser diffuse reflection sensor 11 is parallel to the conveying direction of the conveying belt; the arrangement direction of the third laser diffuse reflection sensor 12 and the fourth laser diffuse reflection sensor 13 is parallel to the conveying direction of the conveying belt; the arrangement direction of the first laser diffuse reflection sensor 10 and the third laser diffuse reflection sensor 12 is perpendicular to the conveying direction of the conveying belt; the arrangement direction of the second laser diffuse reflection sensor 11 and the fourth laser diffuse reflection sensor 13 is perpendicular to the conveying direction of the conveying belt; the detection distance of the first laser diffuse reflection sensor 10, the second laser diffuse reflection sensor 11, the third laser diffuse reflection sensor 12 and the fourth laser diffuse reflection sensor 13 is less than the distance between the sensor and the conveying belt and greater than the distance between the sensor and the upper surface of the cigarette; the distance between the laser emission path of the first laser diffuse reflection sensor 10 and the guide plate 2 close to the first laser diffuse reflection sensor 10 is less than the width of the cigarette; the distance between the third laser diffuse reflection sensor 12 and the guide plate 2 close to the third laser diffuse reflection sensor 12 is less than the width of the cigarette; the distance between the first laser diffuse reflection sensor 10, the second laser diffuse reflection sensor 11 and the laser of the two laser reflection sensors is less than the width of the cigarette; the distance between the third laser diffuse reflection sensor 12, the fourth laser diffuse reflection sensor 13 and the laser of the two laser reflection sensors is less than the width of the cigarette.

[0036] The parameters of the device are designed by taking the standard hard pack cigarette as an example, wherein the standard hard pack cigarette is 280 mm long, 88 mm wide, 47 mm high, and the diagonal line is 295 mm long (the soft pack is 2 mm shorter in height, 10 mm shorter in length, and 10 mm shorter in diagonal line length), the distance between the two side guide plates 2 is 356 mm, the ray distance of the first laser emitter-receiver sensor 3 and the second laser emitter-receiver sensor 4 is 269.7 mm, the distance between the rays of the first laser emitter-receiver sensor 3 and the second laser emitter-receiver sensor 4 is 20 mm, the distance between the rays of the second laser emitter-receiver sensor 4 and the fourth laser emitter-receiver sensor 6 is 20 mm, the distance between the third laser diffuse reflection sensor 12 and the ray of the first laser emitter-receiver sensor 3 is 70 mm, and the distance between the third laser diffuse reflection sensor 12 and the guide plate 2 is 70 mm. The distance between the fourth laser diffuse reflection sensor 13 and the third laser diffuse reflection sensor 12 is 130 mm, the distance between the fourth laser diffuse reflection sensor 13 and the ray of the second laser emitter-receiver sensor 4 is 70 mm, and the first laser diffuse reflection sensor 10 and the second laser diffuse reflection sensor 11 are the same as the third laser diffuse reflection sensor 12 and the fourth laser diffuse reflection sensor 13.

[0037] The four laser diffuse reflection sensors can cooperate with the first laser emitter-receiver sensor 3 and the second laser emitter-receiver sensor 4 to achieve more accurate detection. When the third laser emitter-receiver sensor 5 and the fourth laser emitter-receiver sensor 6 do not detect an object, and the first laser emitter-receiver sensor 3 and the second laser emitter-receiver sensor 4 detect an object, the four laser diffuse reflection sensors will have the following states:

[0038] The first state: when the four laser diffuse reflection sensors do not detect an object at the same time, since the distance between the first laser diffuse reflection sensor 10 and the third laser diffuse reflection sensor 12 and the distance between the second laser diffuse reflection sensor 11 and the fourth laser diffuse reflection sensor 13 are 216 mm, when the cigarette is inclined at an angle of 36°, the length is 269.7 mm and the width is 230.62 mm. It indicates that only one cigarette enters the area and the inclination angle is less than 36°.

[0039] The second state: the third laser diffuse reflection sensor 12 and the fourth laser diffuse reflection sensor 13 detect at the same time, the first laser diffuse reflection sensor 10 and the second laser diffuse reflection sensor 11 do not detect, or the first laser diffuse reflection sensor 10 and the second laser diffuse reflection sensor 11 detect an object, and the third laser diffuse reflection sensor 12 and the fourth laser diffuse reflection sensor 13 do not detect an object, which indicates that only one cigarette enters the area and is close to the running direction of the conveying belt. The angle is less than 36°.

[0040] The third state: only a single one of the four laser diffuse reflection sensors detects, and the others do not detect, which indicates that the inclination angle of the cigarette entering the area is less than 36° and there is only one cigarette.

[0041] Fourth state: More than two of the four laser diffuse reflection sensors detect at the same time, indicating that multiple cigarettes enter the area.

[0042] The blowing mechanism includes blowing pipes arranged on both sides of the conveying belt respectively for blowing the two ends of the cigarette, and the blowing directions of the blowing pipes on both sides are opposite to improve the blowing strength. The blowing mechanism can be provided with multiple groups. In the embodiment, two groups of blowing mechanisms are provided, which include a first blowing pipe 16, a second blowing pipe 17, a third blowing pipe 18, and a fourth blowing pipe 19 in total. The first blowing pipe 16 and the second blowing pipe 17 are located on the same side, and the third blowing pipe 18 and the fourth blowing pipe 19 are located on the other side. Two blowing pipes are arranged correspondingly, and diagonally opposite blowing pipes form a blowing mechanism. This design can cooperate with the arrangement of the four laser diffuse reflection sensors. The first blowing pipe 16 is arranged near the first laser diffuse reflection side. Taking the first blowing pipe 16 and the third blowing pipe 18 on the front side as an example, when the third laser transmission sensor 5 and the fourth laser transmission sensor 6 do not detect an object at the same time, and the first laser transmission sensor 3 and the second laser transmission sensor 4 detect an object at the same time, different blowing pipes are selected for blowing according to the above four different detection states: when the first state is satisfied, it indicates that the cigarette is in the middle area of the conveying belt, and the first blowing pipe 16 and the fourth blowing pipe 19 blow at the same time; when the second state is satisfied, if the third laser diffuse reflection sensor 12 and the fourth laser diffuse reflection sensor 13 detect an object at the same time, it indicates that the cigarette is on one side of the third laser diffuse reflection sensor 12, and the first blowing pipe 16 and the fourth blowing pipe 19 blow at the same time; if the first laser diffuse reflection sensor 10 and the second laser diffuse reflection sensor 11 detect an object at the same time, it indicates that the cigarette is on one side of the first laser diffuse reflection sensor 10, and the second blowing pipe 17 and the third blowing pipe 18 blow at the same time; when the third state is satisfied, when the second laser diffuse reflection sensor 11 or the third laser diffuse reflection sensor 12 detects an object alone, it indicates that the cigarette is in an inclined state with the head close to the second laser diffuse reflection sensor 11 side and the tail close to the third laser diffuse reflection sensor 12 side, and the first blowing pipe 16 and the fourth blowing pipe 19 blow at the same time. When the first laser diffuse reflection sensor 10 or the fourth laser diffuse reflection sensor 13 detects an object alone, it indicates that the cigarette is in an inclined state with the head close to the fourth laser diffuse reflection sensor 13 side and the tail close to the first laser diffuse reflection sensor 10 side, and the second blowing pipe 17 and the third blowing pipe 18 blow at the same time; no blowing in the fourth state. The state of multiple cigarettes belongs to an extremely small probability case, and blowing cannot effectively blow. In this state, only the baffle 20 is used to block, and there is no special requirement for the posture adjustment. If the cigarette is parallel to the conveying direction of the conveying belt after being blocked by the baffle 20, human intervention is required.

[0043] The fifth laser diffuse reflection sensor 14 and the sixth laser diffuse reflection sensor 15 are arranged in front of the baffle 20, the arrangement direction of the fifth laser diffuse reflection sensor 14 and the sixth laser diffuse reflection sensor 15 is perpendicular to the conveying direction of the conveying belt, the detection distance of the fifth laser diffuse reflection sensor 14 and the sixth laser diffuse reflection sensor 15 is less than the distance between the fifth laser diffuse reflection sensor 14 and the sixth laser diffuse reflection sensor 15 and the conveying belt, and greater than the distance between the fifth laser diffuse reflection sensor 14 and the sixth laser diffuse reflection sensor 15 and the upper surface of the cigarette, the fifth laser diffuse reflection sensor 14 and the sixth laser diffuse reflection sensor 15 are symmetrically arranged, the laser emission path spacing of the fifth laser diffuse reflection sensor 14 and the sixth laser diffuse reflection sensor 15 is less than the length of the cigarette, when the fifth laser diffuse reflection sensor 14 and the sixth laser diffuse reflection sensor 15 synchronously detect an object, it represents that the cigarette in the middle of the conveying belt is parallel to the baffle 20, the cigarette is corrected, at this time, the baffle 20 can be switched to the release state first, the laser emission path of the fifth laser diffuse reflection sensor 14 and the sixth laser diffuse reflection sensor 15 and the spacing of the respective distal end guide plate are less than the length of the cigarette, so that the fifth laser diffuse reflection sensor 14 or the sixth laser diffuse reflection sensor 15 can also detect the cigarette when the cigarette is conveyed in close contact, but in this state, the baffle 20 needs to be switched to the release state first after the fifth laser diffuse reflection sensor 14 or the sixth laser diffuse reflection sensor 15 detects the cigarette for a period of time, and the period of time is the time required for the cigarette to be blocked by the baffle 20 and to be corrected, which is inversely proportional to the conveying speed of the conveying belt.

[0044] The setting parameters of the fifth laser diffuse reflection sensor 14 and the sixth laser diffuse reflection sensor 15 are designed taking the standard hard-packed cigarette as an example, and the spacing between the fifth laser diffuse reflection sensor 14 and the sixth laser diffuse reflection sensor 15 is 120 mm.

[0045] A flexible friction pad 21 is vertically arranged in front of the baffle 20, the flexible friction pad 21 can be made of rubber or other materials with flexibility and can increase the friction with the cigarette, when the cigarette passes through the flexible friction pad 21, the flexible friction pad 21 is pushed open and exerts a friction force on the cigarette from above, which can effectively avoid the problem that the posture of the cigarette changes again after the cigarette hits the baffle 20, and the distance between the bottom end of the flexible friction pad 21 and the baffle 20 can be designed to be less than the width of the cigarette.

[0046] A frame 1 can be arranged on the guide plate 2 to provide protection and installation basis for the wiring of the sensor and the arrangement of the air blowing pipe, a glass plate can be arranged above the frame 1 to prevent dust falling and facilitate viewing of the internal dynamics.

[0047] An additional controller 22 can be arranged on the frame 1, the controller 22 is provided with a baffle folding down button, a baffle folding up button and a rotary switch, the rotary switch is used to switch the system to an automatic control state and a manual control state, after being switched to the manual control state, the movement of the baffle 20 can be controlled by using the baffle folding down button and the baffle folding up button.

[0048] The adaptive changes according to actual needs are within the protection scope of the utility model.

[0049] It should be noted that, for those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the utility model.
