Description

Technical Field

[0001] This invention relates to a mosquito coil separating and conveying mechanism and a mosquito coil separating device. Background Technology

[0002] Mosquito coils are widely used in daily life. During manufacturing, the raw material is typically placed on a workbench and pressed into coils using a mold. To improve processing efficiency, each coil consists of two interlocking spiral coils; that is, a first coil and a second coil are interlocking. In the market, mosquito coils are sold in two main packaging methods. First, the coil is packaged as a whole, requiring the user to separate it into two coils. This method saves space, but sometimes the coils break when separating the coil. Second, the coil is divided into two coils before packaging. While this method takes up more space, it is more convenient for consumers. Regarding the second packaging method, the applicant disclosed an improved automatic mosquito coil separation device in Chinese invention patent application CN113060344A entitled "Improved Automatic Mosquito Coil Disc Separation Device". The device includes a top ring corresponding to the first mosquito coil ring, a first driving mechanism for moving the top ring up and down, a support ring corresponding to the second mosquito coil ring, a feeding mechanism for feeding the mosquito coil disc to the support ring, and a picking mechanism for removing the second mosquito coil ring from the support ring. The support ring has a guide hole for the first mosquito coil ring to slide down, and also includes a conveying mechanism for receiving the first mosquito coil ring that slides down from the guide hole.

[0003] In the aforementioned mosquito coil separation device, once the predetermined first and second mosquito coil rings are stacked on the receiving platform and the loading platform, the second drive mechanism lowers the receiving platform and guide cylinder to a position below the upper surfaces of the first and second conveyor belts. Then, the fourth drive mechanism moves the loading platform downwards, ensuring that the first and second mosquito coil rings completely fall onto the first and second conveyor belts. With this structure, the separated first and second mosquito coil rings are initially stacked separately before being transferred to the conveyor belts. If any of the separated mosquito coil rings are defective, such as due to a material breakage, the defective rings will mix and stack with the normal ones, making subsequent processing difficult and affecting the consumer's experience.

[0004] In view of this, the inventors of this case conducted in-depth research on the above-mentioned problems, which led to the creation of this case. Summary of the Invention

[0005] The purpose of this invention is to provide a mosquito coil separation and conveying mechanism that facilitates the detection of abnormal mosquito coil rings. Another purpose of this invention is to propose a mosquito coil separation device using this mosquito coil separation and conveying mechanism.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A mosquito coil separating and conveying mechanism includes a frame, a top ring corresponding to a first mosquito coil ring, a first driving mechanism for moving the top ring up and down, a support ring corresponding to a second mosquito coil ring, and a material-picking mechanism for removing the second mosquito coil ring from the support ring. The support ring has a guide hole for the first mosquito coil ring to slide down. The mechanism also includes a conveying device for receiving the first mosquito coil ring that slides down from the guide hole. The conveying device includes a mounting frame, a drive shaft and a driven shaft mounted on the mounting frame, a power mechanism for driving the drive shaft to rotate, a conveyor belt sleeved on the drive shaft and the driven shaft, and a lifting mechanism for driving the mounting frame to lift up and down. The lifting mechanism is mounted on the frame, and the conveyor belt is correspondingly positioned below the guide hole. The material-picking mechanism is used to pick up and place the second mosquito coil ring onto the conveyor belt.

[0008] In a preferred embodiment of the present invention, the lifting mechanism includes a fixed plate, a lead screw nut installed in the fixed plate, a lead screw passing through the lead screw nut, and a transmission motor for driving the lead screw to rotate. The fixed plate is arranged in a horizontal direction, the lead screw is arranged in a vertical direction, and a guide post is provided on the mounting frame. The guide post is movably arranged in the fixed plate, and the upper end of the lead screw is rotatably mounted on the mounting frame.

[0009] As a preferred embodiment of the present invention, it further includes a tray, the drive motor is mounted on the tray, and the guide post is fixedly connected to the tray.

[0010] In a preferred embodiment of the present invention, the frame is provided with multiple columns, and the columns are provided with a first mounting plate, a lifting plate and a second mounting plate from top to bottom. The top ring is disposed in the lifting plate. The first driving mechanism is a cylinder installed in the first mounting plate. The piston rod of the cylinder is connected to the lifting plate. The support ring is disposed in the second mounting plate. The first mounting plate and the second mounting plate are fixed in the columns.

[0011] In a preferred embodiment of the present invention, the material handling mechanism includes a first pneumatic finger for gripping the second mosquito coil ring, a first lifting drive mechanism for driving the first pneumatic finger to move up and down, and a first traversing mechanism for driving the first lifting drive mechanism to move in the conveying direction of the conveyor belt, wherein the first pneumatic finger is disposed above the conveyor belt.

[0012] As a preferred embodiment of the present invention, the frame is provided with a detection mechanism for detecting whether the mosquito coil is out of material, corresponding to the first mosquito coil ring and the second mosquito coil ring respectively. The detection mechanism is a sensor for detecting whether the end of the mosquito coil ring is out of material, and the sensor is correspondingly arranged above the conveyor belt.

[0013] In a preferred embodiment of the present invention, the sensor is a distance sensor.

[0014] As a preferred embodiment of the present invention, the frame is further provided with a limiting block for restricting the movement of the mosquito coil ring on the conveyor belt. The limiting block is mounted on the frame and can be moved up and down by a lifting cylinder. The limiting block is positioned above the conveyor belt.

[0015] As a preferred embodiment of the present invention, the detection mechanism further includes a stacking mechanism for stacking the detected mosquito coil rings. The stacking mechanism includes a second pneumatic finger, a second lifting drive mechanism for driving the second pneumatic finger to rise and fall, a longitudinal movement mechanism for driving the second lifting drive mechanism to move longitudinally, and a rack for stacking mosquito coil rings. The lower end of the rack is connected to a lifting cylinder for driving the rack to rise and fall. Conveyor belts are provided on both sides of the rack, and the longitudinal direction is a direction perpendicular to the conveying direction of the conveyor belt and extends along the horizontal plane.

[0016] This invention also proposes a mosquito coil separation device, including a frame, a top ring corresponding to a first mosquito coil ring, a first driving mechanism for moving the top ring up and down, a support ring corresponding to a second mosquito coil ring, a feeding mechanism for feeding the mosquito coil disc to the support ring, and a picking mechanism for removing the second mosquito coil ring from the support ring. The support ring has a guide hole for the first mosquito coil ring to slide down. The device also includes a conveying device for receiving the first mosquito coil ring sliding down from the guide hole. The conveying device includes a mounting frame, a drive shaft and a driven shaft mounted on the mounting frame, a power mechanism for driving the drive shaft to rotate, a conveyor belt sleeved on the drive shaft and the driven shaft, and a lifting mechanism for driving the mounting frame to lift up and down. The lifting mechanism is mounted on the frame, and the conveyor belt is correspondingly positioned below the guide hole. The picking mechanism is used to pick up and place the second mosquito coil ring onto the conveyor belt.

[0017] With the technical solution of this invention, the lifting mechanism drives the mounting frame to move upward, thereby receiving the first mosquito coil ring falling from the guide hole of the support ring. The material handling mechanism is used to pick up and place the second mosquito coil ring onto the conveyor belt. The first and second mosquito coil rings are transported to the next process on the conveyor belt. During the transport process, it is possible to observe whether the separated mosquito coil rings are broken. This invention directly uses a liftable conveyor belt. When the conveyor belt rises, it receives the separated mosquito coil rings, reducing the drop difference of the mosquito coil rings. After the conveyor belt descends, it transports the mosquito coil rings, reducing the transport path of the mosquito coil rings and reducing the risk of breakage. Preferably, this invention includes a detection mechanism. Based on the characteristics of mosquito coil rings, it determines whether the mosquito coil rings are abnormal by detecting whether they are broken. The detection mechanism also includes a stacking mechanism for stacking qualified mosquito coil rings to facilitate the next packaging step. Attached Figure Description

[0045] To further explain the technical solution of the present invention, the following detailed description is provided in conjunction with embodiments.

[0046] Reference Figures 1 to 6 A mosquito coil separating and conveying mechanism includes a frame 10, a top ring 71 corresponding to a first mosquito coil ring 21, a first drive mechanism 77 for moving the top ring 71 up and down, a support ring 72 corresponding to a second mosquito coil ring 22, and a material-retrieving mechanism for removing the second mosquito coil ring 22 from the support ring 72. The support ring 72 has a guide hole 73 for the first mosquito coil ring 21 to slide down, and also includes a conveying device for receiving the first mosquito coil ring 21 sliding down from the guide hole 73. These structures have been described in Chinese invention patent application CN113060344A, entitled "Improved Automatic Mosquito Coil Disc Separation Device", and will not be described in detail here. In this invention, the conveying device includes a mounting frame 30, a drive shaft 31 and a driven shaft 32 mounted on the mounting frame 30, a power mechanism (not shown in the figure) for driving the drive shaft 31 to rotate, a conveyor belt 33 sleeved on the drive shaft 31 and the driven shaft 32, and a lifting mechanism for driving the mounting frame 30 to rise and fall. The drive shaft 31 and the driven shaft 32 both extend horizontally and are rotatably mounted on the mounting frame 30. The lifting mechanism is mounted on the frame 10. The conveyor belt 33 is correspondingly positioned below the guide hole 73. The separated first mosquito coil ring 21 can fall from the guide hole 73 onto the conveyor belt 33. The material picking mechanism is used to pick up and place the second mosquito coil ring 22 onto the conveyor belt 33. The conveyor belt 33 drives the first mosquito coil ring 21 and the second mosquito coil ring 22 to be conveyed horizontally.

[0047] In a preferred embodiment of the present invention, the lifting mechanism includes a fixed plate 46, a lead screw nut 44 mounted in the fixed plate 46, a lead screw 43 passing through the lead screw nut 44, and a transmission motor 41 for driving the lead screw 43 to rotate. The fixed plate 46 is arranged horizontally, and the lead screw 43 is arranged vertically. A guide post 45 is provided on the mounting frame 30, and the guide post 45 is movably arranged in the fixed plate 46. The upper end of the lead screw 43 is rotatably mounted on the mounting frame 30. When the lead screw 43 rises, it can drive the mounting frame 30 to rise; when the lead screw 43 falls, the mounting frame 30 can fall under the action of gravity. In a preferred embodiment of the present invention, a support plate 42 is also included. The transmission motor 41 is mounted on the support plate 42, and the guide post 45 is fixedly connected to the support plate 42. The lead screw 43 is driven to rotate by the transmission motor 41. In the embodiment, the transmission motor 41 is connected to the lead screw 43 via belt drive. In this application, the lead screw nut 44 is fixed on the fixing plate 46, which is mounted on the frame 10 and remains stationary. The support plate 42, the drive motor 41, and the lead screw 43 move up and down relative to the lead screw nut 44, thereby driving the mounting frame 30 to move up and down as a whole. When moving upward, it receives the first mosquito coil ring 21 that slides down from the guide hole 73 of the support ring 72, reducing the descent height of the first mosquito coil ring 21 and reducing the risk of the first mosquito coil ring 21 breaking or being damaged. When the mounting frame 30 moves downward, the conveyor belt 33 disengages from the support ring 72, allowing the first mosquito coil ring 21 to be conveyed on the conveyor belt 33. The lifting mechanism of this application is not limited to the above-mentioned lifting mechanism; it can also directly adopt a linear drive mechanism such as a cylinder or an electric push rod to drive the mounting frame 30 to move up and down.

[0048] In a preferred embodiment of the present invention, the frame 10 is provided with multiple columns 78. In this embodiment, four columns are provided. From top to bottom, the columns 78 are provided with a first mounting plate 74, a lifting plate 75, and a second mounting plate 76. The top ring 71 is disposed in the lifting plate 75. The first driving mechanism 77 is a cylinder installed in the first mounting plate 74. The piston rod of the cylinder is connected to the lifting plate 75. The support ring 72 is disposed in the second mounting plate 76. The first mounting plate 74 and the second mounting plate 76 are fixed in the columns 78. These structures have been described in the prior art and will not be described in detail here.

[0049] In a preferred embodiment of the present invention, the material handling mechanism includes a first pneumatic finger 95 for gripping the second mosquito coil ring 22, a first lifting drive mechanism 94 for driving the first pneumatic finger 95 to move up and down, and a first traversing mechanism for driving the first lifting drive mechanism 94 to move in the conveying direction of the conveyor belt 33. The first pneumatic finger 95 is disposed above the conveyor belt 33. In an embodiment, the first traversing mechanism includes a motor 90, a first pulley 91 and a second pulley 92 disposed on the frame 10, and a belt 93 sleeved on the first pulley 91 and the second pulley 92. The output shaft of the motor 90 is driven by the first pulley 91, thereby driving the belt 93 to rotate back and forth within a certain range. The first lifting drive mechanism 94 is fixed on the belt 93. As the belt 93 moves back and forth, the first lifting drive mechanism 94 can be a cylinder.

[0050] In a preferred embodiment of the present invention, the frame 10 is provided with detection mechanisms for detecting whether the mosquito coil is out of material, corresponding to the first mosquito coil ring 21 and the second mosquito coil ring 22. The detection mechanism is a sensor 60 for detecting whether the end 23 of the mosquito coil ring is missing material, and the sensor 60 is positioned above the conveyor belt 33. In a preferred embodiment of the present invention, the sensor 60 is a distance sensor 60. Other sensors 60 with this function can also be used in this application. When the end 23 of the mosquito coil ring is missing material (the end 23 is broken or its position is offset), the sensor 60 receives a signal and determines that the mosquito coil ring is defective. The conveyor belt 33 then directly sends the mosquito coil ring from the end of the conveyor belt 33 into the waste collection device. Additionally, if the mosquito coil ring breaks at other locations, the end 23 will shift during transport, making it undetectable and indicating a quality abnormality. The present invention utilizes the characteristics of mosquito coils to detect most mosquito coil abnormalities, improving work efficiency.

[0051] As a preferred embodiment of the present invention, the frame 10 is further provided with a limiting block 51 for restricting the movement of the mosquito coil ring on the conveyor belt 33. The limiting block 51 is movable up and down on the frame 10 by a lifting cylinder 50. The limiting block 51 is located above the conveyor belt 33. In an embodiment, the limiting block 51 is an arc-shaped block corresponding to the shape of the mosquito coil ring. When the mosquito coil ring moves to the limiting block 51, it is blocked by the limiting block 51 and stops moving. The conveyor belt 33 stops moving, and the detection mechanism detects the mosquito coil ring.

[0052] In a preferred embodiment of the present invention, the detection mechanism further includes a stacking mechanism for stacking the detected mosquito coil rings. The stacking mechanism includes a second pneumatic finger 83, a second lifting drive mechanism 82 for raising and lowering the second pneumatic finger 83, a longitudinal movement mechanism 81 for moving the second lifting drive mechanism 82 longitudinally, and a stacking rack 84 for stacking the mosquito coil rings. The lower end of the rack 84 is connected to a drive cylinder 85 for raising and lowering the rack 84. Conveyor belts 86 are provided on both sides of the rack 84, the longitudinal direction being perpendicular to the conveyor belt 33 and extending along the horizontal plane. The second pneumatic finger 83 is mounted on the second lifting drive mechanism 82, which may be, for example, a cylinder. In this application, one detection mechanism is provided for the first mosquito coil ring 21, and another detection mechanism is provided for the second mosquito coil ring 22. The two detection mechanisms are identical and are located on both sides of the conveyor belt 33. When the mosquito coil rings are found to be qualified, they are clamped onto the material rack 84 and stacked using the second pneumatic finger 83, the second lifting drive mechanism 82, and the longitudinal transfer mechanism 81. When a certain number of mosquito coil rings have been stacked, the drive cylinder 85 lowers the material rack 84, transferring the mosquito coil rings to the conveyor belt 86, which then transports them away. In this application, the longitudinal transfer mechanism 81 can have the same structure as the first transverse transfer mechanism, differing only in the conveying direction.

[0053] This invention also proposes a mosquito coil separation device, including a frame 10, a top ring 71 corresponding to the first mosquito coil ring 21, a first driving mechanism 77 for driving the top ring 71 to move up and down, a support ring 72 corresponding to the second mosquito coil ring 22, a feeding mechanism 100 for feeding the mosquito coil disc to the support ring 72, and a material-retrieving mechanism for removing the second mosquito coil ring 22 from the support ring 72. The support ring 72 is provided with a guide hole 73 for the first mosquito coil ring 21 to slide down. It also includes a conveying device for receiving the first mosquito coil ring 21 sliding down from the guide hole 73. The conveying device adopts the conveying device described above. The feeding device has been described in Chinese invention patent application CN113060344A entitled "Improved Automatic Mosquito Coil Disc Separation Device", and will not be described in detail here.

[0054] The product form of the present invention is not limited to the embodiments described in this case. Any appropriate changes or modifications made to it based on similar ideas should be considered as not departing from the patent scope of the present invention.
