Description
Technical Field
[0001] This utility model relates to the field of scented candle processing technology, specifically to an automatic candle wick filling device. Background Technology
[0002] In the development of automation in candle production, material handling equipment has been widely used on production lines. It can realize the batch delivery of candle wicks and the orderly transfer of candle tins to be inserted, reducing the participation of manual labor in the material handling process and providing a basic guarantee for the continuous operation of the production process. However, the mechanism responsible for material handling and placement in the crucial process of inserting the wick into the candle holder has significant shortcomings. After grasping the wick, this mechanism struggles to accurately adjust to the actual position of the candle holder, often resulting in positional deviations and improper wick installation. Furthermore, the mechanism's transitions between grasping, moving, and placing actions are not smooth enough, with delays in the connections between each step, affecting the efficiency and stability of the filling process and failing to meet production demands. Utility Model Content
[0003] The purpose of this application is to provide an automatic candle wick filling device to solve the problems of inaccurate filling and low efficiency caused by poor position perception and insufficient action coordination of the candle wick picking and placing mechanism in the prior art.
[0004] One aspect of this utility model provides an automatic candle wick filling device, comprising: The wick conveying mechanism is used to output the completed wicks to the wick separating mechanism; The wick separating mechanism is used to receive the wicks output by the wick conveying mechanism and arrange them in an orderly manner to form a wick group that is adapted to be picked up and placed by the wick picking and placing mechanism. Candle holder conveying mechanism, used to convey candle holders to be inserted with wicks; The wick taking and placing mechanism is used to obtain the wick group from the wick separating mechanism and insert the wick group into the corresponding wick can according to the position information of the wick can on the wick can conveying mechanism. The wick separating mechanism is installed on the output end of the wick conveying mechanism, the candle jar conveying mechanism is located below the wick separating mechanism, and the wick picking and placing mechanism is installed on the wick separating mechanism; The wick picking and placing mechanism includes a housing and a wick picking and placing assembly movably connected in the housing. The wick picking and placing assembly includes a picking and placing frame, a driving component, a sliding component, a wick picking and placing head, and a picking and placing clamp. The picking and placing clamp is disposed at the bottom of the picking and placing frame. The driving component and the sliding component are both mounted on the picking and placing frame. A vacuum generator is disposed inside the wick picking and placing head. The wick picking and placing head is mounted on the driving component via the sliding component. Under the drive of the driving component, the wick picking and placing head gradually approaches or moves away from the picking and placing clamp. The vacuum generator is used to pick up or place the wick and the wick assembly. The wick insertion and removal mechanism also includes a sensor group disposed on the candle container conveying mechanism, the sensor group being used to acquire the position information of the candle container to be inserted.
[0005] It should be noted that, in actual use, the housing of the mechanism is also equipped with a drive mechanism that can drive the candle wick picking and placing component to move along a preset trajectory on the housing of the mechanism. Specifically, it can be a drive device of the same type as an electric guide rail. The candle wick picking and placing component can achieve the effect of moving along a preset trajectory under the control of the aforementioned drive device by connecting the picking and placing frame to the aforementioned drive device. Additionally, in actual use, a host computer (described below) is usually externally connected to coordinate the operation of the wick feeding mechanism, candle holder feeding mechanism, and wick picking and placing mechanism according to preset logic. Specifically, the host computer can control the stable feeding of the candle holder feeding mechanism based on the position information of the candle holder to be inserted obtained by the sensor group; simultaneously, it controls the wick feeding mechanism to stably feed the wicks to the wick separating mechanism, so that the wicks form wick groups in the wick separating mechanism, and controls the wick picking and placing mechanism so that the picking and placing head in the wick picking and placing assembly first moves towards the picking and placing clamp. The device gradually approaches the candle wick assembly to retrieve it, then moves away from the wicking fixture. The aforementioned drive device is controlled to move the entire wick retrieval assembly along with the candle container conveying mechanism carrying the candle container to be inserted. Finally, the wick retrieval head is controlled to gradually approach the wicking fixture again and lower the candle wick assembly. The entire wick retrieval assembly is then reset, including resetting the position of the wick retrieval head and the initial position of the entire wick retrieval assembly in the mechanism housing. This completes one instance of coordinated operation of the candle wick conveying mechanism, the candle container conveying mechanism, and the wick retrieval mechanism according to the preset logic.
[0006] It should be noted that, in actual use, the host computer can also add a corresponding driver to control the core-splitting mechanism, so as to control the core-splitting mechanism to join the aforementioned collaborative work. For details, please refer to the description of the core-splitting mechanism below, which will not be repeated here.
[0007] It should be noted that, in actual use, the wick-taking and wick-placing head in the wick-taking and wick-placing mechanism can take and put the wicks into place by setting an electromagnetic adsorption device or similar device inside the structure that contacts the wick-taking and wick-placing head, and then controlling the working state of the electromagnetic adsorption device. This will not be elaborated here. Furthermore, the wick-retrieving head can also be configured as a replaceable structure. Specifically, the structure at the bottom of the wick-retrieving head used for retrieving and placing the wick assembly can be designed as a detachable structure. For example, a detachable wick head can be provided at the bottom of the wick-retrieving head. This detachable wick head can be detachably installed at the bottom of the wick-retrieving head through a snap-fit or slot connection or similar detachable method, allowing the operator to replace different specifications of detachable wick heads according to the actual processing needs of the candle jar to be inserted. Simultaneously, the wick-separating mechanism described below can also have its inner limiting block configured as a replaceable structure, that is, the inner limiting block can be configured as a detachable limiting block. According to the selected detachable wick head specifications, the detachable limiting block can be replaced with one that matches the detachable wick head specifications, so that the wicks are arranged in an orderly manner in the wick-separating mechanism to form wick assemblies that match the detachable wick heads. Through this design, different specifications of detachable wick heads and detachable limiting blocks can be selected before processing to complete different processing tasks of the candle jar to be inserted, further improving the processing range of this utility model.
[0008] In this solution, on the one hand, the sensor group and the wick picking and placing component work together to accurately capture the position information of the candle jar to be inserted, providing a real-time position reference for the wick picking and placing head. This allows the wick picking and placing head to accurately approach or move away from the picking and placing fixture under the control of the drive component. Combined with the orderly arrangement of the wick group by the wick separating mechanism, the wick picking and placing position is precisely aligned with the position of the candle jar to be inserted, solving the problem of inaccurate can filling alignment caused by poor position perception. On the other hand, the layout and coordination between the wick separating mechanism, the wick conveying mechanism, the candle jar conveying mechanism, and the wick picking and placing mechanism shortens the path distance for wick picking and placing, thereby reducing the time spent on action transmission between the mechanisms. This ensures that the wick conveying, wick separating and arranging, wick picking and placing, and candle jar conveying are all carried out in a continuous manner, avoiding delays, interruptions, or jams in the process. This achieves efficient operation of the can filling process and solves the problem of low efficiency caused by insufficient action coordination.
[0009] In one embodiment, the sliding component includes a sliding rod, a slider, and a connecting plate connected to the driving component. The two ends of the sliding rod are respectively installed at the top and bottom of the pick-and-place frame. The slider is fixedly connected to the connecting plate and slidably connected to the sliding rod. The pick-and-place core head is detachably installed on the connecting plate.
[0010] It should be noted that the driving component can be a similar type of electric cylinder. In actual use, the connecting plate can be fixedly connected to both the output end of the driving component and the slider, allowing the connecting plate and the slider to move up and down under the drive of the driving component. By separating the pick-and-place head from the sliding component, the connecting plate can be guided during lifting by the sliding connection between the sliding rod and the slider, avoiding the shaking problem that may occur when the driving component is directly connected to the pick-and-place head during lifting, thus improving the stability of the pick-and-place head during lifting. On the other hand, it can solve the problem that when the pick-and-place head needs to be replaced, it is inevitable to remove the pick-and-place head from the output end of the driving component, thus damaging the driving component itself, and indirectly enhancing the reliability of the driving component.
[0011] In this design, the cooperation of the slide bar, slider, and connecting plate, along with the stable sliding of the slider on the slide bar, provides precise guidance for the lifting and lowering movement of the connecting plate. This avoids the wobbling problem that may occur when the drive unit is directly connected to the wick-picking head, thereby improving the movement stability of the wick-picking head as it approaches or moves away from the wick-picking fixture, ensuring the accuracy of wick picking and can insertion. In addition, the design of detaching and mounting the wick-picking head on the connecting plate eliminates the need for direct contact with the drive unit's output end when replacing the detachable wick head, reducing wear and tear on the drive unit caused by frequent disassembly, thus enhancing the long-term reliability of the drive unit and extending the stable operation cycle of the equipment.
[0012] In one embodiment, the wick-separating mechanism includes an outer stop block and an inner limiting block. The outer stop block encloses a space for accommodating the wick. One side of the outer stop block has an outer notch that connects to the output end of the wick delivery mechanism. The inner limiting block has an inner opening whose shape and size are adapted to the wick. The outer stop block and the inner limiting block cooperate to position the wick in the inner opening to form the wick assembly.
[0013] It should be noted that, in actual use, the wick separating mechanism can be further equipped with a rotary drive device capable of driving the inner limit block to rotate within the outer stop. This device, under the control of the host computer, starts simultaneously with the wick conveying mechanism. Specifically, when the host computer controls the wick conveying mechanism to stably feed material to the wick separating mechanism at a preset conveying rate, the host computer can synchronously control the rotary drive device to operate, driving the inner limit block to rotate within the outer stop at a preset rotational speed. Ideally, the wick conveying mechanism can adjust the rotation of the inner limit block within the outer stop according to the actual processing requirements of the candle tin to be inserted. The block feeds a corresponding number of candle wicks at a preset conveying rate. Through the inner opening on the inner limit block, which rotates at a preset speed, the candle wicks are arranged in an orderly manner in the wick-separating mechanism into a wick group that meets the actual processing requirements of the candle jar to be inserted. The wick-taking and placing mechanism can directly remove the wick group when it is arranged in an orderly manner. During this process, the wick conveying mechanism continuously conveys at a preset rate, the inner limit block rotates continuously at a preset rate, and the wick-taking and placing mechanism continuously cycles to complete the wick group picking and processing of the candle jar to be inserted, which can improve the overall processing efficiency.
[0014] In one embodiment, the wick delivery mechanism includes a main conveyor belt and a delivery track. The delivery track is mounted on the main conveyor belt and has a guide rod for guiding the wick on the main conveyor belt onto the delivery track. The output end of the delivery track is connected to the outer notch.
[0015] In one embodiment, at least two conveying tracks are provided, and at least two core-splitting mechanisms are provided.
[0016] In this solution, by using the outer stop block and the inner limit block of the wick separating mechanism, the range of candle wick movement can be constrained by the containment space formed by the outer stop block, while the inner opening on the inner limit block that is adapted to the shape and size of the candle wick can be used to accurately position the candle wick, so that the candle wick is arranged in an orderly manner to form a standardized candle wick group, which provides a stable foundation for the accurate picking and placing of the candle wick and avoids picking and placing deviations caused by messy candle wick arrangement. In addition, by cooperating with the main conveyor belt, conveyor track and guide rod of the wick conveying mechanism, the wicks on the main conveyor belt can be guided to the conveyor track by the guide rod, ensuring that the wicks are conveyed in a directional manner to the outer notch of the wick separating mechanism, avoiding deviation or accumulation during the conveying process; by setting at least two conveyor tracks and at least two wick separating mechanisms, the parallel conveying and wick separating of multiple sets of wicks can be realized, thereby increasing the wick supply per unit time.
[0017] In one embodiment, the pick-and-place fixture includes an electric guide rail mounted on the bottom surface of the pick-and-place frame. The electric guide rail is connected to an external drive device. A first clamping part and a second clamping part are movably connected to the electric guide rail. Under the control of the external drive device, the first clamping part and the second clamping part move closer to or further away from each other.
[0018] In one embodiment, both the first clamping part and the second clamping part are provided with clamping blocks, and the clamping blocks are adapted to the candle wick container to be inserted.
[0019] It should be noted that in actual use, the external drive device can be connected to the host computer to complete the coordinated control of the pick-and-place fixture in the overall solution. Specifically, when the host computer controls the drive device to drive the candle wick pick-and-place assembly to move along with the candle wick conveying mechanism, it controls the first clamping part and the second clamping part to clamp the candle wick to ensure the stability of the processing. After the processing is completed, the clamping state is released, and the device waits for the next clamping command from the external drive device.
[0020] It should be noted that in actual use, the clamping block can be installed on the first clamping part or the second clamping part through a detachable connection method such as snap-fit or bolt fastening. When replacing the core and inner limit block in the aforementioned scheme, the clamping block can also be replaced according to the shape of the candle jar to be inserted, so as to adapt to the actual processing requirements of the overall equipment.
[0021] In this solution, by cooperating with the electric guide rail and the first clamping part and the second clamping part, the clamping part can be controlled to move closer or further away from the electric guide rail with the help of an external drive device, and to form a stable clamping of the candle to be inserted during the candle wick insertion process, so as to avoid the alignment deviation caused by vibration and displacement of the candle to be inserted during the transportation or processing, and improve the stability of the processing of the candle wick picking and placing mechanism. Additionally, by setting clamping blocks adapted to the candle tins to be inserted on the first clamping part and the second clamping part, the corresponding clamping structure can be matched according to the shape characteristics of candle tins to be inserted of different specifications. Combined with the replaceable design of the core separating mechanism and the core picking and placing head, the adaptability of the equipment to the processing of candle tins to be inserted of different shapes is improved, ensuring that candle tins to be inserted of different specifications can maintain a stable state during the processing. Furthermore, through the collaborative control logic between the pick-and-place fixture and the host computer, the clamping action can be coordinated with the movement rhythm of the candle wick pick-and-place component, achieving dynamic and stable clamping and timely unlocking in the stages of conveying the candle tin to be inserted, inserting the wick, and resetting, thereby further improving the overall processing stability and efficiency of the equipment.
[0022] In one embodiment, the wick-retrieving and placing mechanism further includes a central control device, which controls the wick-retrieving and placing assembly to move along a preset trajectory within the mechanism housing.
[0023] It should be noted that in actual use, the preset trajectory is pre-set to adapt to the actual processing requirements of the overall equipment. Specifically, it can be a horizontal movement, that is, the wick picking and placing component can be displaced in the horizontal direction to complete the continuous following effect of the wick picking and placing head and the wick picking and placing fixture on the wick-to-be-inserted candle can. Synchronous following can be achieved by using the position information of the wick-to-be-inserted candle can obtained by the sensor group to position the wick picking and placing component on the wick-to-be-inserted candle can. And according to the preset wick-to-be-inserted candle can conveying rate of the candle can conveying mechanism itself, the wick picking and placing component can be displaced in the horizontal direction according to the preset main conveying rate.
[0024] In one embodiment, both the wick conveying mechanism and the candle jar conveying mechanism are connected to an external conveying control device, which is used to coordinate the conveying operations of the wick conveying mechanism and the candle jar conveying mechanism.
[0025] It should be noted that the external conveying control equipment can synchronously manage the preset conveying rates of the wick conveying mechanism and the candle jar conveying mechanism, and is uniformly controlled directly by the host computer, making it convenient for operators to set and manage the preset conveying rates of the wick conveying mechanism and the candle jar conveying mechanism.
[0026] In one embodiment, a host computer is also included. The sensor group, the external drive device, the central control device, and the external delivery control device are all electrically connected to the host computer. The host computer is used to coordinate the operation of the external delivery control device, the central control device, and the external drive device according to preset logic based on the position information of the candle wick to be inserted obtained by the sensor group.
[0027] In this solution, by cooperating with the central control equipment and the sensor group, the position information of the candle jar to be inserted can be obtained in real time by the sensor group, and the candle wick picking and placing component can be controlled to follow the displacement of the candle jar according to the preset trajectory. This achieves continuous dynamic positioning of the picking and placing head and the picking and placing fixture of the candle jar to be inserted, avoids misalignment of the insert due to position deviation caused by the conveying of the candle jar, and improves the synchronization accuracy of the picking and placing action and the movement of the candle jar to be inserted. Additionally, by using external conveying control equipment to coordinate the control of the wick conveying mechanism and the candle holder conveying mechanism, the preset conveying rates of both can be managed in a unified manner, ensuring that the wick supply matches the conveying rhythm of the candle holder to be inserted, avoiding processing interruptions or accumulations caused by asynchronous conveying, and improving the continuity of the overall process. In addition, through the electrical connection between the host computer and the sensor group, central control equipment, external conveying control equipment and external drive equipment, the position information of the sensor group can be used as a reference to coordinate the work of each control device in a unified manner according to the preset logic, so as to achieve precise coordination of the entire process from candle wick conveying, candle jar to candle wick insertion and candle wick removal and placement, reduce manual intervention, and improve the convenience of equipment operation and the stability of overall processing.

The wick picking and placing assembly includes a picking and placing frame 42, a driving member 43, a sliding member 44, a wick picking and placing head 45, and a picking and placing clamp 46. The picking and placing clamp 46 is disposed at the bottom of the picking and placing frame 42. The driving member 43 and the sliding member 44 are both mounted on the picking and placing frame 42. A vacuum generator (not shown) is disposed inside the wick picking and placing head 45. The wick picking and placing head 45 is mounted on the driving member 43 through the sliding member 44. Under the drive of the driving member 43, the wick picking and placing head 45 gradually approaches or moves away from the picking and placing clamp 46. The vacuum generator (not shown) is used to pick up or place the wick 14 and the wick assembly 15. The wick picking and placing mechanism 4 includes a mechanism housing 41 and a wick picking and placing assembly movably connected in the mechanism housing 41. The wick picking and placing assembly includes a picking and placing frame 42, a driving member 43, a sliding member 44, a wick picking and placing head 45, and a picking and placing clamp 46. The picking and placing clamp 46 is disposed at the bottom of the picking and placing frame 42. The driving member 43 and the sliding member 44 are both mounted on the picking and placing frame 42. The wick picking and placing head 45 is mounted on the driving member 43 through the sliding member 44. Under the drive of the driving member 43, the wick picking and placing head 45 gradually approaches or moves away from the picking and placing clamp 46. The wick picking and placing mechanism 4 also includes a sensor group 47 disposed on the candle container conveying mechanism 3, the sensor group 47 being used to acquire the position information of the candle container 31 to be inserted with wick.
[0035] It should be noted that, in actual use, the housing 41 is also equipped with a drive mechanism that can drive the candle wick picking and placing assembly to move along a preset trajectory on the housing 41. Specifically, it can be a drive device of the same type as an electric guide rail. The candle wick picking and placing assembly can achieve the effect of moving along a preset trajectory under the control of the aforementioned drive device by connecting the picking and placing frame 42 to the aforementioned drive device. Additionally, in actual use, a host computer (described below) is usually externally connected to coordinate the operation of the wick conveying mechanism 1, the candle holder conveying mechanism 3, and the wick picking and placing mechanism 4 according to preset logic. Specifically, the host computer can control the stable feeding of the candle holder conveying mechanism 3 based on the position information of the candle holder 31 to be inserted obtained by the sensor group 47; simultaneously, it controls the wick conveying mechanism 1 to stably feed the wick to the wick separating mechanism 2, so that the wick 14 forms a wick group 15 in the wick separating mechanism 2, and controls the wick picking and placing mechanism 4 so that the picking and placing head 45 in the wick picking and placing assembly first moves towards the picking and placing clamp 4. The 6 direction gradually approaches to obtain the wick assembly 15, then moves away from the pick-and-place clamp 46, and controls the aforementioned drive device to drive the entire wick pick-and-place assembly to move along with the candle container 31 to be inserted into the candle container conveying mechanism 3. Finally, the pick-and-place head 45 is controlled to gradually approach the pick-and-place clamp 46 again and put down the wick assembly 15. Then the entire wick pick-and-place assembly is reset, including resetting the position of the pick-and-place head 45 and the initial position of the entire wick pick-and-place assembly in the mechanism housing 41. Thus, the coordinated operation of the wick conveying mechanism 1, the candle container conveying mechanism 3 and the wick pick-and-place mechanism 4 according to the preset logic is completed.
[0036] It should be noted that, in actual use, the host computer can also add a corresponding driver to control the core-splitting mechanism 2, so as to control the core-splitting mechanism 2 to join the aforementioned collaborative work. For details, please refer to the description of the core-splitting mechanism 2 below, which will not be repeated here.
[0037] It should be noted that, in actual use, the wick-taking and placement head 45 in the wick-taking and placement mechanism 4 can perform the wick-taking and placement function of the wick assembly 15 by setting an electromagnetic adsorption device or similar device inside the structure in contact with the wick assembly 15, thereby controlling the working state of the electromagnetic adsorption device. This will not be elaborated here. Additionally, the wick-retrieving head 45 can also be configured as a replaceable structure. Specifically, the structure at the bottom of the wick-retrieving head 45 for retrieving and placing the wick assembly 15 can be designed as a detachable structure. For example, a detachable wick head can be provided at the bottom of the wick-retrieving head 45. This detachable wick head can be detachably installed at the bottom of the wick-retrieving head 45 through a snap-fit or slot connection or similar detachable method, allowing the operator to replace different specifications of detachable wick heads according to the actual processing requirements of the candle holder 31 to be inserted. Simultaneously, the wick-separating mechanism 2 described below can also be configured to... The inner limiting block 22 is configured as a replaceable structure, that is, the inner limiting block 22 is configured as a detachable limiting block, so that the detachable limiting block that matches the selected detachable wick head specification can be replaced, so that the wick 14 is arranged in an orderly manner in the wick separating mechanism 2 to form a wick group 15 that matches the detachable wick head; through such design, different specifications of detachable wick heads and detachable limiting blocks can be selected before processing to complete different wick-inserting candle jars 31 processing work, further improving the processing range of this utility model.
[0038] In this embodiment, on the one hand, the sensor group 47, in conjunction with the wick-picking and placing component, can accurately capture the position information of the candle holder 31 to be inserted with wicks, providing a real-time position reference for the action of picking up and placing the wick head 45. This allows the wick-picking and placing head 45 to accurately approach or move away from the picking and placing clamp 46 under the control of the drive component 43. Combined with the orderly arrangement of the wick group 15 by the wick-separating mechanism 2, the picking and placing position of the wick group 15 and the position of the candle holder 31 to be inserted with wicks can be accurately aligned, solving the problem of inaccurate can filling alignment caused by poor position perception. On the other hand, the layout and coordination between the wick-separating mechanism 2, the wick conveying mechanism 1, the candle holder conveying mechanism 3, and the wick picking and placing mechanism 4 can shorten the path distance for picking up and placing the wick 14, thereby reducing the time consumed by the action transmission between the mechanisms. This allows the wick 14 conveying, wick-separating, picking up and placing the wick, and conveying the candle holder 31 to be inserted with wicks to operate continuously, avoiding delays, interruptions, or jams in the process. This achieves efficient operation of the can filling process and solves the problem of low efficiency caused by insufficient action coordination.
[0039] In one embodiment, the sliding component 44 includes a sliding rod 441, a slider 442, and a connecting plate 443 connected to the driving component 43. The two ends of the sliding rod 441 are respectively installed on the top and bottom of the pick-and-place frame 42. The slider 442 is fixedly connected to the connecting plate 443 and slidably connected to the sliding rod 441. The pick-and-place core head 45 is detachably installed on the connecting plate 443.
[0040] It should be noted that the driving component 43 can be a similar type of driving component 43, such as an electric cylinder. In actual use, the connecting plate 443 can be fixedly connected to both the output end of the driving component 43 and the slider 442, so that the connecting plate 443 and the slider 442 can move up and down under the drive of the driving component 43. By separating the picking and placing head 45 entirely from the sliding component 44, on the one hand, the sliding connection between the sliding rod 441 and the slider 442 during the lifting process can guide the connecting plate 443, avoiding the shaking problem of the picking and placing head 45 that may be caused by the driving component 43 directly connecting to the picking and placing head 45 during the lifting process, thereby improving the stability of the picking and placing head 45 during the lifting process. On the other hand, it can solve the problem that when the picking and placing head 45 needs to be replaced, it is inevitable that the picking and placing head 45 needs to be disassembled from the output end of the driving component 43, thereby damaging the driving component 43 itself, and also indirectly enhancing the reliability of the driving component 43.
[0041] In this embodiment, the sliding rod 441, the slider 442, and the connecting plate 443 work together to provide precise guidance for the lifting and lowering movement of the connecting plate 443 by utilizing the stable sliding of the slider 442 on the sliding rod 441. This avoids the wobbling problem that may occur when the drive unit 43 is directly connected to the pick-and-place wick head 45, thereby improving the movement stability of the pick-and-place wick head 45 as it approaches or moves away from the pick-and-place clamp 46, and ensuring the accuracy of the wick assembly 15 pick-and-place and can insertion actions. In addition, by detaching and mounting the pick-and-place wick head 45 onto the connecting plate 443, the replacement operation of the detachable wick head does not require direct contact with the output end of the drive unit 43, reducing the wear and tear on the drive unit 43 caused by frequent disassembly, thereby enhancing the long-term working reliability of the drive unit 43 and extending the stable operation cycle of the equipment.
[0042] In one embodiment, the wick-separating mechanism 2 includes an outer stop block 21 and an inner limiting block 22. The outer stop block 21 encloses a space for accommodating the wick 14. One side of the outer stop block 21 has an outer notch 211 that connects to the output end of the wick delivery mechanism 1. The inner limiting block 22 has an inner opening 221. The shape and size of the inner opening 221 are adapted to the wick 14. The outer stop block 21 and the inner limiting block 22 cooperate to position the wick 14 in the inner opening 221 to form the wick assembly 15.
[0043] It should be noted that, in actual use, the wick separating mechanism 2 can be further equipped with a rotation drive device that can drive the inner limit block 22 to rotate within the outer stop block 21. This device, under the control of the host computer, will start along with the wick conveying mechanism 4. Specifically, when the host computer controls the wick conveying mechanism 1 to stably feed the wick separating mechanism 2 at a preset conveying rate, the host computer can simultaneously control the rotation drive device to work, driving the inner limit block 22 to rotate within the outer stop block 21 at a preset rotation speed. Ideally, the wick conveying mechanism 1 can, according to the actual processing requirements of the candle holder 31 to be inserted, rotate within the outer stop block 21 at a preset speed. The feeding rate corresponds to the number of candle wicks 14. Through the inner opening 221 on the inner limit block 22 rotating at a preset speed, the candle wicks 14 are arranged in an orderly manner in the wick separating mechanism 2 into a candle wick group 15 that meets the actual processing requirements of the candle jar 31 to be inserted. The candle wick picking and placing mechanism 4 can directly remove the candle wick group 15 when it is arranged in an orderly manner. During this process, the candle wick conveying mechanism 1 continuously conveys at a preset speed, the inner limit block 22 continuously rotates at a preset speed, and the candle wick picking and placing mechanism 4 continuously cycles to complete the picking of candle wick group 15 and the processing of the candle jar 31 to be inserted, which can improve the overall processing efficiency.
[0044] In one embodiment, the wick delivery mechanism 1 includes a main conveyor belt 11 and a delivery track 12. The delivery track 12 is mounted on the main conveyor belt 11 and a guide rod 13 is provided on the delivery track 12. The guide rod 13 is used to guide the wick 14 on the main conveyor belt 11 to the delivery track 12. The output end of the delivery track 12 is connected to the outer notch 211.
[0045] In one embodiment, at least two conveying tracks 12 are provided, and at least two core-splitting mechanisms 2 are provided.
[0046] In this embodiment, by cooperating with the outer stop 21 and the inner limit block 22 of the core separating mechanism 2, the range of motion of the candle wick 14 can be constrained by the accommodating space formed by the outer stop 21. At the same time, the inner opening 221 on the inner limit block 22, which is adapted to the shape and size of the candle wick 14, is used to accurately position the candle wick 14, so that the candle wick 14 is arranged in an orderly manner to form a standard candle wick group 15, which provides a stable foundation for the accurate picking and placing of the candle wick picking and placing mechanism 4 and avoids picking and placing deviations caused by the disorderly arrangement of the candle wick 14. Furthermore, through the cooperation of the main conveyor belt 11, the conveyor track 12 and the guide rod 13 of the wick conveying mechanism 1, the wicks 14 on the main conveyor belt 11 can be guided to the conveyor track 12 by the guide rod 13, ensuring that the wicks 14 are directionally conveyed to the outer notch 211 of the wick separating mechanism 2, avoiding deviation or accumulation during the conveying process; by setting at least two conveyor tracks 12 and at least two wick separating mechanisms 2, the parallel conveying and wick separating of multiple sets of wicks 14 can be realized, thereby increasing the supply of wicks 14 per unit time.
[0047] In one embodiment, the pick-and-place clamp 46 includes an electric guide rail mounted on the bottom surface of the pick-and-place frame 42. The electric guide rail is connected to an external drive device. A first clamping part 461 and a second clamping part 462 are movably connected to the electric guide rail. Under the control of the external drive device, the first clamping part 461 and the second clamping part 462 move closer to or further away from each other.
[0048] In one embodiment, both the first clamping part 461 and the second clamping part 462 are provided with clamping blocks 463, which are adapted to the candle holder 31 to be inserted.
[0049] It should be noted that in actual use, the external drive device can be connected to the host computer, and the host computer can complete the coordinated control of the pick-and-place clamp 46 in the overall scheme. Specifically, when the host computer controls the drive device to drive the candle wick pick-and-place assembly to move along with the candle wick 31 to be inserted on the candle wick conveying mechanism 3, it controls the first clamping part 461 and the second clamping part 462 to clamp the candle wick 31 to be inserted in order to ensure the stability of the processing. After the processing is completed, the clamping state is released, and the device waits for the next clamping command from the external drive device.
[0050] It should be noted that, in actual use, the clamping block 463 can be installed on the first clamping part 461 or the second clamping part 462 through a detachable connection method such as a snap-fit connection or a bolt fastening connection. Furthermore, when replacing the core-removing head 45 and the inner limiting block 22 in the aforementioned scheme, the clamping block 463 can also be replaced according to the shape of the candle jar 31 to be inserted, so as to adapt to the actual processing requirements of the overall equipment.
[0051] In this embodiment, by cooperating with the electric guide rail and the first clamping part 461 and the second clamping part 462, the clamping part can be controlled by an external drive device to move closer or further away from the electric guide rail, and to form a stable clamp on the candle jar 31 to be inserted during the insertion of the wick 14, so as to avoid the alignment deviation of the candle jar 31 to be inserted due to vibration or displacement during the transportation or processing, thereby improving the stability of the processing of the wick taking and putting mechanism 4. Additionally, by providing clamping blocks 463 adapted to the candle jar 31 to be inserted into on the first clamping part 461 and the second clamping part 462, the corresponding clamping structure can be matched according to the shape characteristics of the candle jar 31 to be inserted into different specifications. Combined with the replaceable design of the core separating mechanism 2 and the core picking and placing head 45, the adaptability of the equipment to the processing of candle jars 31 to be inserted into different shapes is improved, ensuring that candle jars 31 to be inserted into different specifications can maintain a stable state during the processing. In addition, through the collaborative control logic between the pick-and-place fixture 46 and the host computer, the clamping action can be coordinated with the movement rhythm of the candle wick pick-and-place component, so as to achieve dynamic and stable clamping and timely unlocking in the stages of conveying, inserting, and resetting the candle jar 31 to be inserted, thereby further improving the overall processing stability and processing efficiency of the equipment.
[0052] In one embodiment, the wick removal and placement mechanism 4 further includes a central control device, which is used to control the wick removal and placement assembly to move along a preset trajectory within the mechanism housing 41.
[0053] It should be noted that in actual use, the preset trajectory is pre-set to adapt to the actual processing requirements of the overall equipment. Specifically, it can be a horizontal movement, that is, the wick picking and placing component can move in the horizontal direction to complete the continuous following effect of the wick picking and placing head 45 and the picking and placing clamp 46 on the wick-to-be-inserted candle jar 31. Synchronous following can be achieved by using the position information of the wick-to-be-inserted candle jar 31 obtained by the sensor group 47 to position the wick picking and placing component on the wick-to-be-inserted candle jar 31. And according to the preset conveying rate of the wick-to-be-inserted candle jar 31 of the candle jar conveying mechanism 3 itself, the wick picking and placing component can move in the horizontal direction according to the preset main conveying rate.
[0054] In one embodiment, both the wick conveying mechanism 1 and the candle jar conveying mechanism 3 are connected to an external conveying control device, which is used to coordinate the conveying operation of the wick conveying mechanism 1 and the candle jar conveying mechanism 3.
[0055] It should be noted that the external conveying control equipment can synchronously manage the preset conveying rates of the wick conveying mechanism 1 and the candle jar conveying mechanism 3, and is uniformly controlled directly by the host computer, making it convenient for operators to set and manage the preset conveying rates of the wick conveying mechanism 1 and the candle jar conveying mechanism 3.
[0056] In one embodiment, a host computer is also included. The sensor group 47, the external drive device, the central control device, and the external delivery control device are all electrically connected to the host computer. The host computer is used to coordinate the operation of the external delivery control device, the central control device, and the external drive device according to preset logic based on the position information of the candle jar 31 to be inserted obtained by the sensor group 47.
[0057] In this embodiment, through the cooperation of the central control device and the sensor group 47, the position information of the candle jar 31 to be inserted can be obtained in real time by the sensor group 47, and the candle wick picking and placing component can be controlled to follow the displacement of the candle jar 31 to be inserted according to a preset trajectory. This enables the picking and placing head 45 and the picking and placing clamp 46 to continuously and dynamically position the candle jar 31 to be inserted, avoids misalignment of the insert due to position deviation caused by the conveying of the candle jar 31, and improves the synchronization accuracy between the picking and placing action and the movement of the candle jar 31. Additionally, by using external conveying control equipment to coordinate the control of the wick conveying mechanism 1 and the candle jar conveying mechanism 3, the preset conveying rates of the two can be managed in a unified manner, ensuring that the supply of wick 14 matches the conveying rhythm of the candle jar 31 to be inserted, avoiding processing interruptions or accumulations caused by asynchronous conveying, and improving the continuity of the overall process. In addition, through the electrical connection between the host computer and the sensor group 47, the central control equipment, the external conveying control equipment and the external drive equipment, the position information of the sensor group 47 can be used as a reference to coordinate the work of each control device in a unified manner according to the preset logic, so as to achieve precise coordination of the entire process from the conveying of the candle wick 14, the conveying of the candle jar to be inserted wick 31 to the picking and placing of the candle wick 14, reduce manual intervention, and improve the convenience of equipment operation and the stability of overall processing.
[0058] The overall operation process of one preferred embodiment of this utility model is described in detail below: Before starting this utility model, the operator needs to make adaptation adjustments to the replaceable parts according to the actual processing requirements of the candle jar 31 to be inserted: the operator first removes the detachable core head at the bottom of the core-removing head 45 and replaces it with a new detachable core head that is compatible with the specifications of the candle jar 31 to be inserted; at the same time, the inner limiting block 22 in the core-separating mechanism 2 is replaced with a new detachable limiting block that is compatible with the specifications of the new detachable core head, so as to ensure that the candle wick 14 can form a candle wick group 15 of the corresponding specifications in the core-separating mechanism 2; if the shape of the candle jar 31 to be inserted changes, the clamping blocks 463 of the first clamping part 461 and the second clamping part 462 on the core-removing fixture 46 also need to be replaced with a new clamping block 463 that is compatible with the shape of the new candle jar 31 to be inserted, thus completing the specification adaptation preparation before equipment processing. After the operator sets the overall preset parameters, the equipment is started. The host computer begins to coordinate the work of each mechanism according to the preset logic: the wick conveying mechanism 1 starts to operate, the completed wick 14 is fed from the main conveyor belt 11, and under the guidance of the guide rod 13, it enters the two conveying tracks 12 from the main conveyor belt 11, and then is directionally conveyed along the conveying track 12 to the outer notch 211 of the wick separating mechanism 2; the outer block 21 of the wick separating mechanism 2 surrounds and forms a receiving space. After the wick 14 enters, the inner limit block 22 rotates in the outer block 21 through the rotation drive device. Its inner opening 221 cooperates with the outer block 21 to accurately position the wick 14 in the inner opening 221 and arrange them in an orderly manner to form a wick group 15 that is adapted to pick up and put down the wick head 45. Synchronously, the candle tin conveying mechanism 3 starts, and the candle tin conveying mechanism 3 transports the candle tins 31 to be inserted into the processing area in sequence. The sensor group 47 set on the candle tin conveying mechanism 3 acquires the position information of the candle tins 31 to be inserted into in real time and feeds it back to the host computer. The host computer controls the external conveying control equipment according to the position information to control the conveying speed of the candle tin conveying mechanism 1 and the candle tin conveying mechanism 3 to keep them matched. Synchronously, the wick picking and placing mechanism 4 starts working under the control of the central control equipment. The driving component 43 drives the connecting plate 443 and the slider 442 to rise and fall along the slide rod 441. The picking and placing head 45 follows the connecting plate 443 to approach the picking and placing clamp 46. The vacuum generator (not shown) in the picking and placing head 45 starts to generate negative pressure and picks up the arranged wick group 15 from the wick separating mechanism 2. Then the driving component 43 drives the picking and placing head 45 away from the picking and placing clamp 46. Under the control of the central control equipment, the driving mechanism in the mechanism housing 41 drives the wick picking and placing assembly to move along the preset trajectory, so that the picking and placing head 45 and the picking and placing clamp 46 move with the wick-to-be-inserted candle can 31 on the candle can conveying mechanism 3. During the movement, the host computer controls the external driving equipment to make the first clamping part 461 and the second clamping part 462 of the picking and placing clamp 46 move closer to each other along the electric guide rail. The new clamping block 463 after replacement forms a stable clamp on the wick-to-be-inserted candle can 31 to prevent it from shifting during the processing. When the wick-picking and placing assembly moves directly above the candle holder 31 to be inserted, the drive unit 43 again drives the wick-picking and placing head 45 to approach the wick-picking and placing clamp 46 along the slide bar 441. The vacuum generator (not shown) stops working and releases the negative pressure, accurately placing the wick assembly 15 into the candle holder 31 to be inserted. After the wick is inserted, the first clamping part 461 and the second clamping part 462 move away from each other under the control of the external drive device, releasing the clamp on the candle holder 31 to be inserted. At this time, the candle holder 31 to be inserted becomes the finished candle holder 32 and leaves the processing area with the candle holder conveying mechanism 3. At the same time, the drive mechanism drives the wick-picking and placing assembly to reset as a whole, and the wick-picking and placing head 45 returns to the initial position under the action of the drive unit 43, ready for the next picking and placing cycle.
[0059] During the above process, the host computer continuously coordinates the central control equipment to adjust the displacement trajectory of the candle wick picking and placing component, the external conveying control equipment to maintain the synchronous conveying rate, and the external drive equipment to control the timing of the clamping action through the information fed back by the sensor group 47, so as to ensure the continuous operation of each link of candle wick 14 conveying, wick arrangement, picking and placing inserts and candle container conveying.
[0060] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
