Description

Technical Field

[0001] The invention relates to the technical field of cigarette box unloading, and in particular to a cigarette box posture adjustment and conveying system. Background Art

[0002] In the unloading environment of truck container assembly lines, cigarette boxes are usually transported to chain conveyors or roller conveyor lines manually, and then the barcode or QR code pasted on the surface of the cigarette box is read by the rear-end code reader for identification and storage. In order to cooperate with the scanner of the rear-end code reader, workers need to flip the side of the cigarette box with the barcode or QR code to face the scanner when carrying the cigarette box. That is, if the scanner is located above the conveyor line, the side of the cigarette box with the barcode or QR code needs to be flipped to the top. If the scanner scans from the side of the conveyor line, the side of the cigarette box with the barcode or QR code needs to be flipped to face the scanner. When manually flipping the side of the cigarette box with the barcode or QR code to face the scanner, it is necessary to first observe the side of the cigarette box with the barcode or QR code, and then flip it. The cigarette box cannot be thrown directly or placed at will, which reduces the unloading efficiency and increases the labor intensity of the workers.

[0003] In order to improve the efficiency of cigarette box unloading, some manufacturers choose to equip the front end of the chain conveyor or roller conveyor line with flipping equipment to achieve normal docking with the automatic code reading equipment. However, most of the existing flipping equipment flips the cigarette box in a fixed direction, basically only in one fixed direction, with a single motion logic and limited movement paths for the cigarette box at a single station.

DETAILED DESCRIPTION

[0041] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] like Figure 1-Figure 13As shown, an embodiment of the present invention provides a cigarette box posture adjustment conveying system, comprising a conveyor 1, an identification mechanism, a control system and a posture adjustment mechanism; the identification mechanism comprises a plurality of cameras, which are connected to the control system signal and are used to identify target features on each surface of the cigarette box 6; the posture adjustment mechanism is installed on the conveyor 1 and is connected to the control system signal, which is used to judge the real-time posture of the cigarette box 6 according to the position of the target feature on the cigarette box 6, and control the posture adjustment mechanism according to the real-time posture to adjust the cigarette box 6 to the target posture; the conveyor 1 comprises a frame and a roller conveyor line mounted on the frame, and the roller conveyor line comprises a plurality of rollers; the posture adjustment mechanism comprises:

[0043] The flip assembly 2 includes a rotating shaft 207, a plurality of flip fork plates 208, and a driving component. The rotating shaft 207 is located below the roller conveyor line, and its axis direction is perpendicular to the axis direction of the roller; the flip fork plate 208 has a first bearing surface and a second bearing surface connected to each other, and the angle between the first bearing surface and the second bearing surface is greater than or equal to 90°. The plurality of flip fork plates 208 are arranged and installed on the rotating shaft 207 along the axis direction of the rotating shaft 207, and each flip fork plate 208 is located in the gap between two adjacent rollers on the roller conveyor line. The driving component is used to drive the rotating shaft 207 to rotate around its axis;

[0044] The horizontal rotating assembly 4 includes a bearing base 408, a lifting mechanism and a rotating mechanism. The bearing base 408 is fixed on the rotating mechanism, and its upper surface is used to bear the cigarette box 6. The rotating mechanism is used to drive the bearing base 408 to rotate around its own axis; the lifting mechanism is used to drive the bearing base 408 to rise and fall, so that it is higher or lower than the conveying surface of the roller conveyor line.

[0045] In this embodiment, it should be clear that the unloading conveyor line includes a first conveyor line close to the truck container, a conveyor 1 in this embodiment, and a second conveyor line, and the first conveyor line, the conveyor 1, and the second conveyor line are connected end to end in sequence. The identification mechanism is located at the first conveyor line. After the cigarette box 6 enters the first conveyor line, the camera of the identification mechanism identifies the target features (barcode 601 or QR code) on each surface of the cigarette box 6 on the first conveyor line. Then the cigarette box 6 enters the conveyor 1. The control system determines the real-time posture of the cigarette box 6 according to the position of the barcode 601 or QR code on the cigarette box 6, and controls the posture adjustment mechanism on the conveyor 1 according to the real-time posture to adjust the cigarette box 6 to the target posture. Finally, the cigarette box 6 enters the third conveyor line, and the scanning gun is set at the third conveyor line to scan the barcode 601 or QR code on the cigarette box 6.

[0046] For example, it is assumed that the scanner is arranged above the third conveyor line, and it scans the cigarette box 6 downward. Then, after the control system determines the real-time posture of the cigarette box 6 according to the position of the barcode 601 or the two-dimensional code on the cigarette box 6, it controls the posture adjustment mechanism on the conveyor 1 to adjust the cigarette box 6 so that the side where the barcode 601 or the two-dimensional code is located faces upward. In this way, the barcode 601 or the two-dimensional code on the surface of the cigarette box 6 entering the third conveyor line will be successfully scanned by the scanner.

[0047] The posture adjustment mechanism in this embodiment includes a flip assembly 2 and a horizontal rotation assembly 4, which are sequentially installed on the conveyor 1 from the feeding end to the discharging end of the conveyor 1. After the cigarette box 6 enters the roller conveying line of the conveyor 1, it will first move to the position of the flip fork plate 208, and then the control system controls the driving component to drive the rotating shaft 207 to rotate 90° counterclockwise around its axis, thereby driving the flip fork plate 208 to rotate 90° counterclockwise to flip the cigarette box 6, so that the cigarette box 6 rotates 90° counterclockwise, and preliminarily adjusts the position of the side of the cigarette box 6 where the barcode 601 or the two-dimensional code is located.

[0048] Next, the cigarette box 6 is further moved to the top of the supporting base 408, and then the control system controls the lifting mechanism to drive the supporting base 408 to rise and fall so that it is higher than the conveying surface of the roller conveyor line. Then the control system controls the rotating mechanism to drive the supporting base 408 to rotate around its own axis, and adjusts the position of the side where the barcode 601 or the QR code is located on the cigarette box 6 again.

[0049] After the posture of the cigarette box 6 is adjusted twice by the flipping component 2 and the horizontal rotating component 4, the side of the cigarette box 6 where the barcode 601 or the two-dimensional code is located can finally face the scanning gun.

[0050] It can be seen that this embodiment can automatically adjust the posture of the cigarette box 6, so that the cigarette box 6 can be scanned smoothly by the scanner, and there is no need to manually adjust the posture of the cigarette box 6, which greatly improves the unloading efficiency and reduces the labor intensity of workers. Moreover, facing the complex incoming box forms in the container unloading scenario, this posture adjustment mechanism can meet the posture adjustment of most incoming box types under the condition of determining the box turning logic, and is compatible with cigarette boxes 6 of different sizes.

[0051] It should be noted that the target feature on the cigarette box 6 includes one or more of a QR code, a barcode 601, and a sealing tape 602. Preferably, the target feature is the barcode 601.

[0052] In other embodiments of the present invention, the target features on the cigarette box 6 also include trademarks, patterns, warning signs, etc. In actual use, the target features can be selected according to the needs of adjusting the posture of the cigarette box 6.

[0053] It should be noted that the barcode 601 on the cigarette box 6 is generally attached to the left or right side surfaces or the top surface of the cigarette box 6. Fig.13 In the embodiment, the barcode 601 is usually attached to the two side surfaces of the cigarette box 6 in the X direction and the top surface in the Z direction.

[0054] As a preferred embodiment, Figure 2 and Figure 3 As shown, the flip assembly 2 includes a base plate 201, a movable base 205 and two bearing seats 206, and the driving components include a linear module 202 and a connecting rod 209. The base plate 201 is fixedly mounted on the frame on a beam below the roller conveyor line, and the length direction of the base plate 201 is the same as the width direction of the conveyor 1. The linear module 202 is fixedly mounted on the base plate 201, and the lower surface of the movable base 205 is connected to the sliding block on the linear module 202. The sliding block on the linear module 202 can drive the movable base 205 to move along the length direction of the linear module 202, that is, along the width direction of the conveyor 1. The two bearing seats 206 are respectively fixed at the two ends of the movable base 205, and the two ends of the rotating shaft 207 are respectively connected to the bearings in the two bearing seats 206.

[0055] Furthermore, a plurality of flip fork plates 208 are arranged along the length direction of the rotating shaft 207 and fixed on the rotating shaft 207. Figure 4 As shown, it includes a first plate 2081, a second plate 2082 and a third plate 2083 connected to each other, wherein the first plate 2081 is perpendicular to the second plate 2082, one end of the third plate 2083 is connected to the connection between the first plate 2081 and the second plate 2082, and the third plate 2083 is fixed on the rotating shaft 207. The angle between the third plate 2083 and the first plate 2081 is an obtuse angle, and the angle between the second plate 2082 and the third plate 2083 is also an obtuse angle, and the first plate 2081, the second plate 2082 and the third plate 2083 form a Y-shaped plate.

[0056] Figure 4 In the embodiment, the upper surface of the first plate 2081 forms the first bearing surface, and the right side surface of the second plate 2082 forms the second bearing surface. The first bearing surface and the second bearing surface are surfaces for contacting the cigarette box 6 when the cigarette box 6 is turned over.

[0057] In this embodiment, the first end of the connecting rod 209 is hinged to the second plate 2082 , and the second end of the connecting rod 209 is hinged to the bottom plate 201 .

[0058] It should be clear that when the flip assembly 2 is in the initial state, Figure 2As shown, the first plate 2081 is parallel and the second plate 2082 is vertical. When the cigarette box 6 needs to be rotated 90° counterclockwise, the cigarette box 6 enters the conveyor 1 and moves to the top of the flip fork plate 208 along the roller conveyor line. At this time, the cigarette box 6 is located above the first plate 2081, and then the linear module 202 drives the movable base 205 to drive the flip fork plate 208 to move to the right side. However, due to the traction of the connecting rod 209, the flip fork plate 208 rotates counterclockwise while moving to the right side. When the flip fork plate 208 rotates 90° counterclockwise, the linear module 202 stops working. At this time, the first plate 2081 rotates to a vertical state, and the second plate 2082 rotates to a horizontal state, so as to drive the cigarette box 6 to rotate 90° counterclockwise.

[0059] After that, no-load reset is performed, that is, the linear module 202 drives the movable base 205 to drive the flip fork plate 208 to move to the left side. Under the action of the connecting rod 209, the flip fork plate 208 rotates clockwise while moving to the left side until the flip fork plate 208 rotates 90° clockwise to reach the position shown in FIG. Figure 2 In the state shown, the linear module 202 is suspended.

[0060] As a specific embodiment, two base plates 201 are provided, and two linear modules 202 are also provided. A linear module 202 is fixedly installed on each base plate 201. Figure 3 As shown, a fixed seat 210 is also provided between the ends of the two bottom plates 201, and the fixed seat 210 is also fixedly installed on the crossbeam below the roller conveyor line. Two connecting rods 209 are provided, and the first ends of the two connecting rods 209 are hingedly installed on the fixed seat 210, and the second ends of the two connecting rods 209 are respectively hinged on the second plate bodies 2082 of the two flip fork plates 208.

[0061] In order to improve the stability of the mobile base 205 during lateral movement, Figure 2 As shown, a guide rail 203 is installed on each of the two bottom plates 201 , and at least one slider 204 is slidably installed on the guide rail 203 , and the top of the slider 204 is fixedly connected to the lower surface of the moving base 205 .

[0062] It should be noted that the distance that the linear module 202 drives the movable base 205 to move horizontally determines the rotation angle of the flip fork plate 208. Figure 3As shown, a first photoelectric sensor 211 and a second photoelectric sensor 212 are sequentially installed on a bottom plate 201 along its length direction, and a signal sheet is installed on the lower surface of the movable base 205. When the flip assembly 2 is in the initial state, the signal sheet is located in the first photoelectric sensor 211, and the first photoelectric sensor 211 feeds back a signal to the control system, indicating that the flip fork plate 208 is in the initial state, that is, the first plate body 2081 is parallel and the second plate body 2082 is vertical.

[0063] When the signal piece moves to the second photoelectric sensor 212, the second photoelectric sensor 212 feeds back a signal to the control system, indicating that the flip fork plate 208 has reached the limit position. At this time, the first plate body 2081 is vertical and the second plate body 2082 is horizontal. The control system immediately controls the linear module 202 to stop working.

[0064] The first photoelectric sensor 211 and the second photoelectric sensor 212 can strictly control the flip angle of the flip fork plate 208.

[0065] In this embodiment, the identification mechanism includes a support frame and multiple cameras. The above-mentioned first conveyor line passes through the support frame, that is, the support frame spans the first conveyor line. Multiple cameras are installed on the support frame. The multiple cameras shoot the cigarette box 6 on the first conveyor line from different angles to obtain the target features of the cigarette box 6.

[0066] It should be noted that there are many options for the number of cameras to be installed and the installation angles, which will not be elaborated in detail here, as long as they can meet the requirements of photographing the smoke box 6 from multiple angles.

[0067] As a preferred embodiment, Figure 1 and Fig.10 As shown, the horizontal rotating assembly 4 includes a bearing base 408, a lifting mechanism and a rotating mechanism. The bearing base 408 is fixed on the rotating mechanism, and its upper surface is used to bear the cigarette box 6. The rotating mechanism is used to drive the bearing base 408 to rotate around its own axis; the lifting mechanism is used to drive the bearing base 408 to rise and fall, so that it is higher or lower than the conveying surface of the roller conveyor line.

[0068] In this embodiment, the horizontal rotation component 4 includes a fixed frame 401 and a movable platform 402, wherein the fixed frame 401 is fixedly installed on the crossbeam of the conveyor 1 below the roller conveyor line, and four circular holes are opened at the four corners of the bottom of the fixed frame 401, and four guide rods 403 are provided at the bottom of the movable platform 402, and the four guide rods 403 are respectively inserted into the four circular holes on the fixed frame 401.

[0069] The rotating mechanism includes a rotating shaft 404, a reducer and a second motor 405. A circular hole is opened on the upper surface of the moving platform 402, and a bearing seat is installed at the circular hole. The bottom end of the rotating shaft 404 passes through the circular hole and is matched with the bearing seat. The output end of the reducer and the rotating shaft 404 are connected through gear transmission, and the output end of the second motor 405 is connected to the input end of the reducer. The bearing base 408 is fixedly installed on the top of the rotating shaft 404.

[0070] The lifting mechanism includes a hydraulic cylinder 406 fixedly installed at the bottom of the fixed frame 401 . The cylinder end of the hydraulic cylinder 406 passes through the fixed frame 401 and is fixed to the lower surface of the moving platform 402 .

[0071] The supporting base 408 is generally in the shape of a cross bar, which includes a rectangular block and fixing bars fixed on four sides of the rectangular block. Two fixing bars are fixed on each of the four sides of the rectangular block, for a total of eight fixing bars. Fig.13 As shown, the roller conveyor line includes a first roller conveyor area, a second roller conveyor area and a third roller conveyor area, wherein the first roller conveyor area includes a plurality of first conveyor rollers 101, and the plurality of first conveyor rollers 101 are arranged and extend from the feed end of the conveyor 1 to a position close to the middle of the conveyor 1. The second roller conveyor area includes a plurality of second conveyor rollers 103, and the third roller conveyor area includes a plurality of third conveyor rollers 104. A partition seat 102 is provided between the second roller conveyor area and the third roller conveyor area, and the second conveyor rollers 103 and the third conveyor rollers 104 are symmetrically arranged about the partition seat 102.

[0072] like Figure 1 As shown, in the initial state, the rectangular block in the supporting base 408 is located inside the partition seat 102, and the four fixing rods in the front and rear directions of the rectangular block are also located inside the partition seat 102, while the two fixing rods on the left side of the rectangular block are located in the gap between two adjacent second conveying rollers 103, and the two fixing rods on the right side of the rectangular block are located in the gap between two adjacent third conveying rollers 104.

[0073] After being flipped by the flip assembly 2, the cigarette box 6 is transported by the first roller conveying area to the second roller conveying area and the third roller conveying area. Driven by the second conveying roller 103 and the third conveying roller 104, the cigarette box 6 moves to the top of the supporting base 408. Then, the hydraulic cylinder 406 extends to push the moving platform 402 to drive the rotating shaft 404 and the supporting base 408 to rise together, so as to lift the cigarette box 6 to a certain height. Then, the second motor 405 is turned on to drive the rotating shaft 404 to rotate around its own axis to a set angle, so as to drive the cigarette box 6 on the supporting base 408 to rotate the set angle.

[0074] It should be noted that the rotation angle of the rotation axis 404 each time is 90° or a multiple of 90°, such as 180°, 270° and 360°.

[0075] In order to ensure that the rotation angle of the smoke box 6 is 90° or a multiple of 90°, Fig.10 As shown, four fourth photoelectric sensors 407 are installed on the upper surface of the moving platform 402, and the four fourth photoelectric sensors 407 are evenly distributed around the axis of the rotating shaft 404, that is, the central angle between two adjacent fourth photoelectric sensors 407 is 90°. A signal piece is fixedly installed on the side of the rotating shaft 404, and when the rotating shaft 404 rotates one circle, the signal piece will pass through the four fourth photoelectric sensors 407 in sequence.

[0076] Thus, every time the rotating shaft 404 rotates 90°, a fourth photoelectric sensor 407 will receive a signal and send it to the control system. This ensures that the horizontal rotating assembly 4 drives the cigarette box 6 to rotate horizontally by multiples of 90° each time, thus avoiding the problem of the cigarette box 6 tilting after rotation.

[0077] It should be noted that the cigarette box 6 may be tilted to a certain extent after being flipped by the flip assembly 2, so that after the horizontal rotation assembly 4 drives the cigarette box 6 to rotate horizontally, the cigarette box 6 is still tilted to a certain extent. The tilted cigarette box 6 is not conducive to the subsequent scanning work of the scanner.

[0078] In order to solve this technical problem, in this embodiment, Figure 1 As shown, a centering adjustment assembly 3 is installed on the conveyor 1, and the centering adjustment assembly 3 includes two push plates 320 and a centering drive mechanism. The two push plates 320 are arranged above the roller conveyor line along the axis direction of the rollers of the roller conveyor line, that is, the two push plates 320 are respectively located on the left and right sides of the bearing base 408, and are symmetrical about the bearing base 408. The centering drive mechanism is used to drive the two push plates 320 to move closer to or away from each other.

[0079] After the cigarette box 6 flipped by the flip assembly 2 moves to the top of the supporting base 408, the centering drive mechanism drives the two push plates 320 to move closer to each other, and pushes the cigarette box 6 from the left and right sides of the cigarette box 6 respectively to straighten the slightly tilted cigarette box 6.

[0080] The centering adjustment component 3 mainly plays two roles. First, it straightens the slightly tilted cigarette box 6 to prevent centrifugal tipping during subsequent rotation. Second, it pushes the cigarette box 6 to the middle position of the roller conveyor line, that is, moves it to the center position of the bearing base 408 to prevent centrifugal tipping during subsequent rotation.

[0081] In this embodiment, the centering drive mechanism can be implemented in a variety of structures, such as using two cylinders to push the two push plates 320 respectively. Alternatively, a bidirectional threaded rod mechanism is used, the threads on both sides of the threaded rod are in opposite directions, the two push plates 320 are respectively screwed to the threads on both sides of the threaded rod, and then a motor is used to drive the threaded rod to rotate around its own axis.

[0082] As a specific embodiment, Figure 6 , Figure 7 and Figure 8 As shown, in this embodiment, a belt drive is used to drive the two push plates 320 to move closer to or away from each other. Specifically, the centering adjustment assembly 3 includes a first mounting plate 301, a second mounting plate 302, two first sliding rails 303, two second sliding rails 304, a first moving frame 305 and a second moving frame 306.

[0083] The first mounting plate 301 and the second mounting plate 302 are fixed on the crossbeam below the roller conveying line of the conveyor 1, and the first mounting plate 301 and the second mounting plate 302 are arranged along the conveying direction of the conveyor 1, and the length direction of the first mounting plate 301 and the second mounting plate 302 is perpendicular to the conveying direction of the conveyor 1. Two first sliding rails 303 are fixedly mounted on the first ends of the first mounting plate 301 and the second mounting plate 302, respectively, and two second sliding rails 304 are fixedly mounted on the second ends of the first mounting plate 301 and the second mounting plate 302, respectively.

[0084] The first mobile frame 305 and the second mobile frame 306 have the same structure, and both include a top plate 324 and two legs 323 fixed on both sides of the bottom of the top plate 324. The two legs 323 at the bottom of the first mobile frame 305 are slidably mounted on the two first sliding rails 303, and the two legs 323 at the bottom of the second mobile frame 306 are slidably mounted on the two second sliding rails 304. The two push plates 320 are mounted on the top plates 324 of the first mobile frame 305 and the second mobile frame 306, respectively.

[0085] In this embodiment, the centering drive mechanism includes a drive shaft 308, a transmission belt 319, a first belt 315, a second belt 316, a first transmission pulley 317, a second transmission pulley 318, a first fixed pulley 310, a second fixed pulley 311, two third fixed pulleys 312, two pulley mounting seats 309, two bearing mounting seats 307 and a first motor 330.

[0086] Specifically, a bearing mounting seat 307 is fixedly mounted on the upper surface of the first end of the first mounting plate 301 and the second mounting plate 302, respectively, a pulley mounting seat 309 is mounted on the upper surface of the second end of the first mounting plate 301 and the second mounting plate 302, respectively, and two third fixed pulleys 312 are rotatably mounted on the two pulley mounting seats 309. The driving shaft 308 is rotatably mounted between the two bearing mounting seats 307, and the first transmission pulley 317, the first fixed pulley 310 and the second fixed pulley 311 are fixedly mounted on the driving shaft 308 in sequence. Furthermore, a vertical plate is fixedly installed on the lower surface of the first end of the first mounting plate 301, the first motor 330 is fixedly installed on the vertical plate, and a second transmission pulley 318 is fixedly installed on the output end of the first motor 330, the first transmission pulley 317 is located directly above the second transmission pulley 318, the transmission belt 319 is sleeved between the first transmission pulley 317 and the second transmission pulley 318, the first belt 315 is sleeved between the first fixed pulley 310 and the third fixed pulley 312 at the second end of the first mounting plate 301, and the second belt 316 is sleeved between the second fixed pulley 311 and the third fixed pulley 312 at the second end of the second mounting plate 302.

[0087] Furthermore, the two legs 323 at the bottom of the first mobile frame 305 are respectively connected to the upper parts of the first belt 315 and the second belt 316. The two legs 323 at the bottom of the second mobile frame 306 are respectively connected to the lower parts of the first belt 315 and the second belt 316.

[0088] In this way, the control system controls the first motor 330 to work, and the first motor 330 drives the second transmission pulley 318 to rotate. Since the transmission belt 319 is sleeved between the first transmission pulley 317 and the second transmission pulley 318, it can drive the drive shaft 308 to rotate around its own axis, thereby driving the first fixed pulley 310 and the second fixed pulley 311 to rotate around the axis of the drive shaft 308 at the same time. In addition, the first belt 315 is sleeved between the first fixed pulley 310 and the third fixed pulley 312 at the second end of the first mounting plate 301, and the second belt 316 is sleeved between the second fixed pulley 311 and the third fixed pulley 312 at the second end of the second mounting plate 302, thereby driving the first belt 315 and the second belt 316 to move synchronously. In addition, the two legs 323 at the bottom of the first mobile frame 305 are respectively connected to the upper half of the first belt 315 and the second belt 316. The two legs 323 at the bottom of the second movable frame 306 are respectively connected to the lower parts of the first belt 315 and the second belt 316, so that the first movable frame 305 and the second movable frame 306 can be moved closer to or farther away from each other, that is, the two push plates 320 can be moved closer to or farther away from each other.

[0089] It should be clear that if Figure 1As shown, the legs 323 at the bottom of the first mobile frame 305 are located in the gap between two adjacent second conveying rollers 103 in the second roller conveying area. Similarly, the legs 323 at the bottom of the second mobile frame 306 are located in the gap between two adjacent third conveying rollers 104 in the third roller conveying area.

[0090] In this embodiment, if Figure 6 As shown, the two legs 323 at the bottom of the first mobile frame 305 are connected to the upper part of the first belt 315 and the second belt 316 using the first fixing clamp 313. The two legs 323 at the bottom of the second mobile frame 306 are connected to the lower part of the first belt 315 and the second belt 316 using the second fixing clamp 314.

[0091] In order to avoid the problem of damaging the cigarette box 6 when the push plate 320 pushes the cigarette box 6 to correct its posture. Figure 8 and Fig. 9 As shown, an elastic member 329 is fixedly installed between the push plate 320 and the top plate 324, a detection block 326 is installed on the side of the push plate 320 facing the top plate 324, and a proximity switch 328 is installed on the top plate 324. The proximity switch 328 is an ultrasonic proximity switch, and the proximity switch 328 points to the detection block 326. When the push plate 320 pushes the cigarette box 6, the push plate 320 is subjected to a reaction force and moves toward the top plate 324 to compress the elastic member 329, and at the same time, the distance between the detection block 326 and the proximity switch 328 is reduced. When it is reduced to within a set range, the control system controls the first motor 330 to stop working, so that the push plate 320 stops.

[0092] It should be understood that the ultrasonic proximity switch works by transmitting and receiving high-frequency sound waves. First, the transmitter sends out a series of ultrasonic pulses, which are reflected back after encountering the detection block 326 and captured by the receiver. By measuring the time it takes for the sound waves to go back and forth, the position of the detection block 326 can be known.

[0093] Optionally, the proximity switch 328 may also be replaced by a distance sensor with a sufficiently fast response speed, such as a photoelectric distance sensor.

[0094] In this embodiment, the elastic member 329 is a rubber column or a spring.

[0095] In this embodiment, if Fig. 9 A stopper 327 is also installed on the side of the push plate 320 facing the top plate 324. The length of the stopper 327 is greater than the length of the detection block 326. Its function is to prevent the push plate 320 from hitting the top plate 324 to reserve sufficient safety space.

[0096] In addition, if Figure 8As shown, a slot plate 321 is installed on the side of the first mounting plate 301, and a plurality of third photoelectric sensors 322 are installed on the slot plate 321 along its length direction. A signal sheet 325 used in conjunction with the third photoelectric sensor 322 is installed on the leg 323 located above the first mounting plate 301 at the bottom of the first moving frame 305, and the third photoelectric sensor 322 is connected to the control system for communication. The position of the moving frame is determined by the third photoelectric sensor 322.

[0097] As a preferred embodiment, Figure 1 As shown, a height limiting component 5 is installed above the discharge end of the conveyor 1, and the height limiting component 5 is used to intercept the cigarette box 6 so that the standing cigarette box 6 is blocked and falls down.

[0098] Specifically, Fig.11 and Fig.12 As shown, the height limiting assembly 5 includes a first fixed bottom block 501, a second fixed bottom block 502, a threaded rod 504, a first vertical rod 505, a second vertical rod 506, an active lifting block 507, a driven lifting block 508, a height limiting rod 509, a top box 503 and a rotating handle 510.

[0099] The first fixed bottom block 501 and the second fixed bottom block 502 are respectively fixedly mounted on both sides of the top of the discharge end of the conveyor 1, at least one vertically arranged first upright pole 505 is fixedly mounted on the first fixed bottom block 501, at least one vertically arranged second upright pole 506 is fixedly mounted on the second fixed bottom block 502, and the top box 503 is fixed between the top of the first upright pole 505 and the top of the second upright pole 506. Further, the threaded rod 504 is rotatably mounted between the first fixed bottom block 501 and the top box 503, and the top of the threaded rod 504 passes through the top box 503, and the rotating handle 510 is fixedly connected to the top of the threaded rod 504 for shaking the threaded rod 504. The active lifting block 507 is threadedly connected to the threaded rod 504 and is slidably connected to the first upright pole 505, the driven lifting block 508 is slidably connected to the second upright pole 506, and the height limiting rod 509 is fixed between the active lifting block 507 and the driven lifting block 508.

[0100] By shaking and rotating the handle 510 to drive the threaded rod 504 to rotate, the height limiting rod 509 can be driven to rise and fall.

[0101] It should be clear that if Fig.14 As shown, when the end face of the cigarette box 6 in the Y direction falls on the roller conveyor line of the conveyor 1, it is necessary to use the height limiting component 5 to intercept the cigarette box 6. The cigarette box 6 falls over under the blocking action of the height limiting rod 509, so that the end face of the cigarette box 6 in the Y direction no longer acts on the roller conveyor line.

[0102] Preferably, in order to accurately adjust the height of the height-limiting rod 509, Fig.12As shown, a vertically arranged scale 512 is provided on one side of the first fixed bottom block 501 , and a pointer 511 is provided on the end surface of the active lifting block 507 , and the pointer 511 points to the scale 512 .

[0103] In summary, in the present posture adjustment conveying system for cigarette box 6, the cigarette box 6 is successively adjusted in posture by the flipping assembly 2, the horizontal rotation assembly 4 and the height limiting assembly 5, so as to ensure that the side of the cigarette box 6 where the barcode 601 is located is adjusted to face the scanner. That is, the present posture adjustment mechanism can formulate different adjustment strategies according to the real-time posture of the cigarette box 6, adjust the cigarette box 6 to the target posture, and can meet the posture adjustment requirements of most incoming cargo boxes when the flipping logic is determined.

[0104] In order to improve the adaptability to cigarette boxes 6 of different sizes, the control system includes a storage component. The storage component stores a shape database of the cigarette box 6. The shape database includes size data corresponding to various cigarette boxes 6. The control system determines the real-time posture of the cigarette box 6 according to the target characteristics and the size data corresponding to the cigarette box 6, and controls the posture adjustment mechanism to adjust the cigarette box 6 to the target posture according to the real-time posture.

[0105] After the user inputs all the dimension data of the cigarette box 6 that needs to be adjusted into the shape database, the control system can directly call the dimension data in the shape database when determining the real-time posture of the cigarette box 6, so as to more quickly identify the real-time posture of the cigarette box 6.
