[0039] Please see Figures 1 to 13 The present invention discloses a high-speed continuous tilting conveyor 100, comprising: a frame 101, a first double-row conveyor belt 102, a second double-row conveyor belt 103, a telescopic tilting mechanism 104, and a tilting blocking mechanism 105.

[0040] The first double-row conveyor belt 102 is located at one end of the frame 101, and the second double-row conveyor belt 103 is located at the other end of the frame 101. The telescopic flipping mechanism 104 is located between the first double-row conveyor belt 102 and the second double-row conveyor belt 103. The telescopic flipping mechanism 104 is used to flip the object to be flipped on the first double-row conveyor belt 102. The flipping blocking mechanism 105 is set on the frame 101. The flipping blocking mechanism 105 is located at the end of the first double-row conveyor belt 102 away from the second double-row conveyor belt 103 and is used to prevent the next object to be flipped from entering the first double-row conveyor belt 102.

[0041] The frame 101 includes a rectangular frame 1011 and a plurality of legs 1012, with the plurality of legs 1012 arranged in an array below the rectangular frame 1011. The length direction of the rectangular frame 1011 is the conveying direction, and the width direction is perpendicular to the conveying direction.

[0042] The object to be flipped can be a box 300, which is a flat cubic structure. During transportation, it can be placed flat (with the larger side placed horizontally). When it is about to reach the palletizing area, it can be flipped up and placed vertically (with the larger side placed vertically) to facilitate the picking up of the box 300 by a person or a robot.

[0043] The first double-row conveyor belt 102 is connected to the external telescopic conveyor line 200. Specifically, the conveying surface of the first double-row conveyor belt 102 is arranged horizontally and is flush with the conveying surface of the telescopic conveyor line 200.

[0044] The telescopic flipping mechanism 104 includes a flipping bracket 1041, a flipping drive component 1042, a first rotating shaft 1043, a telescopic bracket 1044, and a telescopic drive component 1045;

[0045] The first rotating shaft 1043 passes through the tilting bracket 1041. The two ends of the first rotating shaft 1043 are movably mounted on the inner walls of both sides of the frame 101. A transmission wheel 1046 is provided on the first rotating shaft 1043. The tilting drive component 1042 is located at the bottom of the frame 101 and is drivenly connected to the transmission wheel 1046. The tilting drive component 1042 is located between the first double-row conveyor belt 102 and the second double-row conveyor belt 103. The tilting bracket 1041 includes a first plate a with a T-shaped structure and a second plate b connected to the first plate a. A telescopic drive component 1045 is located at the end of the first plate a away from the second plate b. The telescopic drive component 1045 passes through the second plate b. The telescopic bracket 1044 is slidably connected to the first plate a. The telescopic bracket 1044 passes through the second plate b and can extend out of the second plate b. When the telescopic bracket 1044 extends out, it can form a cross-shaped structure with the first plate a and the second plate b.

[0046] Specifically, a mounting base 1013 is provided on each side of the frame 101. The two ends of the first rotating shaft 1043 are mounted on the two mounting bases 1013. The tilting drive 1042 drives an intermediate wheel (not shown) that cooperates with the transmission wheel 1046 to rotate, thereby driving the transmission wheel 1046 to rotate. The transmission wheel 1046 drives the first rotating shaft 1043 to rotate. The first rotating shaft 1043 is fixedly connected to the tilting bracket 1041, and the first rotating shaft 1043 rotates together with the tilting bracket 1041. The first plate a and the second plate b are connected in the middle to form a T-shaped structure. Optionally, the first plate a and the second plate b can be an integral structure or a separate structure. Optionally, the tilting drive 1042 is a motor, and the telescopic drive 1045 is a cylinder, hydraulic cylinder, or electric cylinder. The second plate b has an opening in the middle for the telescopic bracket 1044 to pass through. The first plate a includes an end plate and two side plates, which are connected to the two ends of the end plate respectively. The telescopic drive member 1045 is connected to the end plate. Each of the two side plates is provided with a telescopic slide rail 1047. The telescopic bracket 1044 is slidably connected to the two telescopic slide rails 1047. The telescopic drive member 1045 drives the telescopic bracket 1044 to extend and retract, which can be retracted into the first plate a or extended out of the second plate b to form a cross-shaped structure with the first and second plates. Further, a first suction cup 1048 is provided at least one end of the second plate b. Optionally, in this embodiment, a first suction cup 1048 is provided at one end of the second plate b. The flipping drive member 1042 drives the transmission wheel 1046 to drive the flipping bracket 1041 to rotate continuously, or even rotate a full circle, thereby flipping the box 300 from its flat position conveyed by the first double-row conveyor belt 102 to an upright position. The transmission wheel 1046 includes, but is not limited to, sprockets and synchronous pulleys. The connection between the tilting drive 1042 and the transmission wheel 1046 includes, but is not limited to, chain drive and belt drive. The first suction cup 1048 is a vacuum suction cup. The first suction cup 1048 is used to pick up and fix the box 300 during the tilting process and release it when the tilting ends, so as to reduce the risk of tipping over during the tilting process and improve the stability of the tilting process. The telescopic bracket 1044 is driven by the telescopic drive 1045 to extend or retract in a straight line. Furthermore, a rotating air distribution block 1049 is also provided at one end of the first rotating shaft 1043. The rotating air distribution block 1049 is connected to an external compressed air source and vacuum suction cups, cylinders, etc. through an air pipe, which can realize the connection of the compressed air path under the continuous rotation of the telescopic tilting mechanism 104. When the telescopic bracket 1044 extends, it forms a cross-shaped windmill together with the tilting bracket 1041. After the box 300 is in place, it rotates to continuously tilt the box 300 to change the posture of the box 300. When the telescopic support 1044 retracts, the flipping support 1041 stops flipping, so that the first double-row conveyor belt 102 can convey the box 300 in a flat position to pass through without changing the posture of the box 300.The telescopic flipping mechanism 104 is equipped with a first detection sensor on its side to detect whether the housing 300 is in position and a second detection sensor to detect whether the telescopic bracket 1044 is retracted in position. The first and second detection sensors can be, but are not limited to, photoelectric sensors. The first detection sensor detects that the housing 300 has reached the standard position of the telescopic flipping mechanism 104 and sends a signal to initiate the flipping action; the second detection sensor detects whether the telescopic bracket 1044 is retracted in position and sends a signal back.

[0047] The flipping blocking mechanism 105 includes a driving element 1051, a support 1052, a second rotating shaft 1053, a torsion spring 1054, and a flipping blocking block 1055;

[0048] The drive element 1051 is driven to connect with the support 1052, the second rotating shaft 1053 passes through the support 1052, the torsion spring 1054 is sleeved on the second rotating shaft 1053, and the flipping blocking block 1055 is sleeved on the second rotating shaft 1053.

[0049] Specifically, the drive element 1051 is mounted on the frame 101, and the output end of the drive element 1051 is connected to the support 1052. The support 1052 has several protrusions c, and the second rotating shaft 1053 passes through each protrusion c. A torsion spring 1054 is sleeved between each two adjacent protrusions c. The flipping blocking block 1055 has a "[" shaped structure, with both ends sleeved on both ends of the second rotating shaft 1053. Optionally, in this embodiment, the flipping blocking block 1055 has opposing blocking surfaces d and inclined surfaces e. The inclined surface e faces the telescopic flipping mechanism 104, and the blocking surface d faces away from the telescopic flipping mechanism 104. The inclined surface e can be flipped under pressure to be flush with the upper end surface of the support 1052. In fact, the end face of the support 1052 is the upper end face of the protrusion c. Furthermore, a flipping guide rod 1056 is also provided, which is disposed on both sides of the drive element 1051 and connected to the support 1052. The drive element 1051 can be a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder. Specifically, the torsion spring 1054 has two torsion feet, one of which abuts against the support 1052 and the other of which abuts against the tilting stop block 1055.

[0050] Furthermore, it also includes a third double-row conveyor belt 106, which is mounted on the frame 101 and is located at the end of the second double-row conveyor belt 103 away from the first double-row conveyor belt 102. The third double-row conveyor belt 106 is also a double-row conveyor belt.

[0051] An electric idler mechanism 107 is provided between the third double-row conveyor belt 106 and the second double-row conveyor belt 103. The electric idler mechanism 107 includes an idler bracket 1071 and an electric roller 1072. The idler bracket 1071 is mounted on the frame 101, and the electric roller 1072 is mounted on the idler bracket 1071. The electric idler mechanism 107 provides power and support for the transition conveying of the box 300 from the second double-row conveyor belt 103 to the third double-row conveyor belt 106, preventing the box 300 from tipping over during the transition conveying process and improving conveying efficiency and stability. The upper surface of the electric roller 1072 is flush with the conveying surfaces of both the second double-row conveyor belt 103 and the third double-row conveyor belt 106. Preferably, in this embodiment, the electric idler mechanism 107 further includes two mounting plates 1073 and two unpowered rollers 1074. The two mounting plates 1073 are respectively mounted on both ends of the idler bracket 1071, and both ends of each unpowered roller 1074 are respectively mounted on the two mounting plates 1073. The highest position on the two unpowered rollers 1074 is flush with the conveying surface of the second double-row conveyor belt 103 and the conveying surface of the third double-row conveyor belt 106.

[0052] Furthermore, it also includes an automatic pitch control mechanism 108, which includes a centering drive 1081, an intermediate shaft 1082, a first ball screw 1083, a second ball screw 1084, a first side bracket 1085, and a second side bracket 1086.

[0053] A centering guide rail 1014 is provided on the frame 101. A first side bracket 1085 is slidably connected to the centering guide rail 1014, and a second side bracket 1086 is slidably connected to the centering guide rail 1014. A centering drive component 1081 is drivenly connected to an intermediate shaft 1082. A first ball screw 1083 and a second ball screw 1084 are respectively connected to the two ends of the intermediate shaft 1082. The threads on the first ball screw 1083 and the threads on the second ball screw 1084 have opposite directions of rotation. The first side bracket 1085 is connected to the first ball screw 1083 by a first nut 1087 sleeved on the first ball screw 1083. The second side bracket 1086 is connected to the second ball screw 1084 by a second nut 1088 sleeved on the second ball screw 1084. The first side bracket 1085 and the second side bracket 1086 are respectively located on both sides of the frame 101 and can move in a centered manner. The first ball screw 1083 is connected to one end of the intermediate shaft 1082 via a first coupling, and the second ball screw 1084 is connected to the other end of the intermediate shaft 1082 via a second coupling. Since the threads of the first ball screw 1083 and the second ball screw 1084 have opposite directions, the centering drive 1081 drives the intermediate shaft 1082 to rotate in one direction, causing both the first ball screw 1083 and the second ball screw 1084 to rotate in the same direction. However, the first nut 1087 and the second nut 1088 move in opposite directions, allowing for centering and separation. This, in turn, causes the first side bracket 1085 and the second side bracket 1086 to be centered and clamped or to separate and loosen, thereby achieving centering and clamping of multiple boxes 300 after they have been conveyed to their positions, ensuring their sides are flush. This method is suitable for horizontal positioning and alignment of boxes 300 of different sizes and specifications. Optionally, the centering drive 1081 can be a motor, driven and connected to the intermediate shaft 1082 via a belt or chain. The conveying guide length range of the first side support 1085 and the second side support 1086 includes the conveying distance range of the first double-row conveyor belt 102, the second double-row conveyor belt 103, and the third double-row conveyor belt 106. This allows the automatic pitch-changing mechanism 108 to simultaneously horizontally center and clamp multiple boxes 300 of the first double-row conveyor belt 102, the second double-row conveyor belt 103, and the third double-row conveyor belt 106 while the boxes 300 are being conveyed or flipped, resulting in high work efficiency. Preferably, the first side support 1085 and the second side support 1086 are equipped with a distance measuring grating f.The ranging grating f includes two grating optical axes. One grating optical axis is set on the first side bracket 1085, and the other grating optical axis is set on the second side bracket 1086. The two grating optical axes are mutually emitted to detect each other. The ranging grating f detects the position of the grating optical axis blocking after the box 300 is transported to the position. The presence of the box 300 can be calculated or determined from the position of the grating optical axis blocking. If it is present, it can detect whether each box 300 is in place and whether it is tilted at a certain angle. The detection principle is as follows: the two grating optical axes of the ranging grating f are directly opposite each other and emit opposing light. When a box 300 is present, it will form a blockage. If multiple boxes 300 are in close contact, no light will pass through. If there is a gap (for example, the box 300 is not fully in place or the tilt causes the boxes 300 to not be tightly attached), light will pass through.

[0054] Furthermore, a tilting limiting structure 109 is provided near one end of the telescopic tilting mechanism 104 close to the second double-row conveyor belt 103. The tilting limiting structure 109 includes a gantry frame 1091 mounted on the frame 101 and several rollers 1092 mounted on the gantry frame 1091. The rollers 1092 are located above the box 300. During tilting, the tilting limiting structure 109 can be adjusted to forward / backward, up / down, and rotational positions to limit the upper boundary of the box 300 during the tilting process of the telescopic tilting mechanism 104, preventing the box 300 from tipping over during high-speed tilting.

[0055] The first double-row conveyor belt 102, the second double-row conveyor belt 103, and the third double-row conveyor belt 106 each include two conveyor belts. In this embodiment, the first double-row conveyor belt 102, the second double-row conveyor belt 103, and the third double-row conveyor belt 106 have similar structural designs, differing only in size. Each includes two belts h, two drive shafts i, four rollers j, and a conveyor belt drive component k. The conveyor belt drive component k is driven and connected to one or two drive shafts i, and the connection method can adopt existing technology. The four rollers j are sleeved on both ends of the two drive shafts i, and the two belts h are respectively sleeved on the two rollers j on the two drive shafts i. A frame l is provided between the two belts h of the third double-row conveyor belt 106 and part of the second double-row conveyor belt 103, wherein the frame l and the third double-row conveyor belt 106 do not contact each other. A lifting drive m is provided at the lower end of the frame l. Optionally, the lifting drive m is one of a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder. The lifting drive m is mounted on the frame 101. At the same time, two vertically extending lifting guide rods n are provided at the lower end of the frame l. The lifting guide rods n are set on the frame 101. The lifting drive m moves the frame l up and down. The frame l and the lifting drive m form a lifting mechanism.

[0056] The conveying surfaces of the first double-row conveyor belt 102, the second double-row conveyor belt 103, and the third double-row conveyor belt 106 are all arranged laterally. Optionally, in this embodiment, the conveyor belt drive component k is a servo stepless speed-regulating motor with stepless speed regulation function.

[0057] The first double-row conveyor belt 102, the second double-row conveyor belt 103, the telescopic flipping mechanism 104, the flipping blocking mechanism 105, the third double-row conveyor belt 106, the flipping limiting structure 109, and the automatic pitch-changing mechanism 108 are all mounted on the frame 1011. Preferably, since various conveyor belt structures and the housing 300 pass through the frame 101 above the frame 101, in this embodiment, the various driving components, such as motors or cylinders, can be mounted on the lower side of the frame 1011, with the driving components extending downwards. The driving components of the first double-row conveyor belt 102, the second double-row conveyor belt 103, the telescopic flipping mechanism 104, the flipping blocking mechanism 105, the third double-row conveyor belt 106, and the automatic pitch-changing mechanism 108 are all servo motors, which can achieve precise control and speed matching of motion parameters during the conveying and flipping of the housing 300, and effective connection of motion processes in different conveying stages. For composite robots working on planes, slopes, and other conditions, different motor process parameters can be used, allowing for flexible and efficient adaptation to various working conditions.

[0058] Furthermore, a baffle 1015 is provided at one end of the frame 101 where the third double-row conveyor belt 106 is located. A buffer structure 1016 is provided on the side of the baffle 1015 facing the conveyor surface. The buffer structure 1016 can be an elastic block. The buffer structure 1016 can effectively prevent the packaging box 300 from impacting the baffle 1015 and causing noise due to rapid movement of the conveyor line. At the same time, it can effectively prevent the box 300 from tipping backward due to impact. A second suction cup 1017 is provided on the buffer structure 1016. Optionally, a robot arm is provided on the outside of the third double-row conveyor belt 106 for picking up the box 300 placed on the third double-row conveyor belt 106. Preferably, the buffer structure 1016 is telescopic, driven by a drive structure and guided by a guide rod. The drive structure is one of a cylinder, a hydraulic cylinder, or an electric cylinder. Several second suction cups 1017 are provided, for example, three are provided in this embodiment. This invention provides a high-speed continuous flipping conveyor line with multiple operating modes. For example, in operating mode one, the packaging box 300 flips from a lying position to an upright position. Multiple boxes 300 are arranged in a group and then picked up, transported, and palletized by a robot in one go. The number of boxes 300 in a group can be 1, 2, 3, 4, or even more. Each packaging box 300 on the third double-row conveyor belt 106 has a third detection sensor to detect its arrival, including but not limited to gratings and photoelectric switches. Taking a single group of 4 boxes 300 as an example: the third double-row conveyor belt 106 can buffer a maximum of 2 upright boxes. When 2 boxes 300 are in position on the third double-row conveyor belt 106, the conveying operation stops immediately, while the second double-row conveyor belt 103 continues conveying until the remaining 2 boxes 300 are in position. Compared to using a single-segment conveyor line, this effectively prevents and reduces excessive friction and wear on the bottom surface of the boxes 300 caused by continuous conveying when the first 2 boxes 300 are in position. Once all boxes 300 in a group are simultaneously triggered by their arrival signals, the robot gripper picks them up and moves them. In working mode two, the boxes 300 are transported in a horizontal position to the end of the conveyor line, where they are grouped into a single group (1 or 2 boxes) by an automatic pitch-changing mechanism 108, and then picked up and moved by the robot gripper. In some application scenarios, because working mode two involves horizontal transport and the boxes 300 are relatively low, the reachability and picking efficiency of the robotic arm are limited. Therefore, a lifting mechanism needs to be installed in this mode to raise the two horizontally lying boxes 300 to a corresponding compensating height, significantly improving robot reachability and picking efficiency. During depalletizing, the conveyor line can be depalletized by reversing the actions of working mode one or working mode two.

[0059] This invention provides a high-speed continuous flipping conveyor line. After the box 300 is conveyed onto the first double-row conveyor belt 102, it is flipped by the telescopic flipping mechanism 104, realizing automated conveying and flipping of the box 300. The flipping blocking mechanism 105 prevents the next object adjacent to the object to be flipped from entering the first double-row conveyor belt 102, making the flipping smoother and more effective. The flipping limiting structure 109 controls the posture of the box 300 during flipping, making the flipping smoother and more effective. The centering drive component 1081 can center and clamp multiple boxes 300 after they are conveyed to their positions, making their sides flush. This is suitable for horizontal positioning and alignment of boxes 300 of different sizes and specifications. This conveyor line, in conjunction with a robot, requires no manual intervention and can improve the automation and efficiency of high-speed palletizing and depalletizing of packaging boxes 300 in industries such as tobacco, food, pharmaceuticals, and express delivery. Currently, similar conveyor lines in the industry have a cycle time of about 10 seconds, while this invention completes the process in no more than 7 seconds. The weight of the packaging box 300 can reach up to 23 kg. All high-speed continuous tilting conveyor lines are driven by double-row synchronous belts, which can effectively prevent the packaging box from becoming unstable or even tipping over due to the gaps in traditional roller conveyor lines. The continuous stability is better than that of traditional roller conveyor lines.
