Description

Technical Field

[0001] This utility model relates to the technical field of automated production equipment for traditional Chinese medicine, and in particular to a device for picking up and placing bucket lids. Background Technology

[0002] In the automated production of traditional Chinese medicine decoction, the weighing, dispensing, slag removal, and liquid filling of medicinal materials have been largely automated, significantly improving production efficiency and process stability. During production, the prescribed medicinal materials are first placed into open medicine barrels, and after dispensing (either automatically or semi-automatically), the barrels are then covered before entering the decoction process. Therefore, in continuous production lines, automatic lid handling is required at multiple workstations. To adapt to the production line's pace, the lid handling device must balance operational efficiency and layout flexibility, especially requiring the ability to complete lid handling on one side of the production line to avoid interfering with other processes. Therefore, developing an automated device suitable for traditional Chinese medicine decoction lines that can accurately and efficiently grasp and place lids has become an urgent technical problem to be solved.

[0039] This utility model proposes a bucket lid picking and placing device 100, which aims to provide an automated bucket lid picking and placing device suitable for Chinese medicine decoction lines, capable of accurately and efficiently picking up and placing bucket lids.

[0040] Please see Figures 1 to 3 In one embodiment of this utility model, the bucket lid picking and placing device 100 includes a housing 1 and a picking and placing mechanism 2. The housing 1 has an opening a on one side in the longitudinal direction. The picking and placing mechanism 2 includes a mounting base 21 and a picking part 22. The mounting base 21 is movably mounted on the housing 1 in the vertical direction, and the picking part 22 is movably mounted on the mounting base 21 in the transverse direction. The picking part 22 has a picking and placing stroke in the vertical direction and a conveying stroke in the transverse direction. The picking part 22 is used to pick up or place the bucket lid 200 in the picking and placing stroke and to convey the picked bucket lid 200 in the transverse direction in the conveying stroke. The picking part 22 extends at least partially outward from the opening a so that the picking part 22 can pick up the bucket lid 200 located outside the housing 1 at the loading station and place the picked bucket lid 200 at the unloading station outside the housing 1.

[0041] Understandably, the housing 1, as the main supporting structure of the whole, has an opening a on one side along the longitudinal direction. This opening a is used for the working end of the loading and unloading mechanism 2 to extend outward and connect with the external loading and unloading stations. The structural design of the housing 1 can be adapted according to the actual installation space, and its material can be metal or high-strength engineering plastic to ensure structural rigidity and long-term operational stability.

[0042] The pick-and-place mechanism 2 includes a mounting base 21 and a pick-up part 22. The mounting base 21 is movably mounted in the housing 1 in the vertical direction and can achieve precise vertical guiding movement through a guide structure such as a guide rail 32 in cooperation with a slider.

[0043] The reciprocating motion of the mounting base 21 is driven by a vertical drive device. This drive device can be in the form of a cylinder, an electric push rod, a servo motor with a lead screw and nut structure, etc. This manual does not limit its specific structure. It can be a cam drive, a linkage mechanism, or a linear motor, etc., which will not be described in detail here.

[0044] The pickup unit 22 is movably mounted on the mounting base 21 in the lateral direction and can reciprocate in the horizontal direction relative to the mounting base 21. This lateral movement is realized by a horizontal drive device. The drive method can be a pneumatic slide, a synchronous belt mechanism driven by a stepper motor, or a ball screw transmission mechanism, etc. The specific form can be selected according to the requirements of stroke accuracy and response speed. This specification does not limit this embodiment.

[0045] In addition, the end effector of the pickup unit 22 can be a suction cup, a gripper or a magnetic structure, depending on the material and structure of the lid 200. Of course, other possible shapes can also be used. The specific shape can be determined according to the actual situation. This specification does not limit this embodiment.

[0046] It should be noted that the picking unit 22 has a vertical picking and placing stroke and a horizontal conveying stroke. During the picking and placing stroke, the picking unit 22 uses vertical movement to grasp the barrel cover 200 located at the loading station or release the barrel cover 200 located at the unloading station.

[0047] After picking up the lid 200, the picking unit 22 rises to a safe height along with the mounting base 21, and then moves laterally to above the unloading station under the action of the horizontal drive device, before descending to complete the lid placement action. The picking unit 22 is provided to extend at least partially outward from the opening a of the housing 1, ensuring that its working range covers the loading and unloading stations outside the housing 1, thereby realizing the picking and placing operation in a single-sided layout, effectively saving the lateral space of the equipment, and facilitating integration into a compact production line.

[0048] By setting up a pick-and-place mechanism 2 with a vertically movable mounting base 21 and a horizontally movable pick-up part 22, and cooperating with the side opening a layout of the housing 1, the automatic pick-and-place operation of the bucket lid 200 is realized on one side of the production line. This structural design allows the device to be flexibly arranged on one side of the production line without reserving operating space on both sides of the production line, saving equipment space and improving the compactness and flexibility of the production line layout. Through the coordinated control of the vertical stroke and the horizontal transfer stroke, the pick-up part 22 can accurately and stably complete the entire process of picking up the bucket lid 200 from the loading station and transferring it to the unloading station, with smooth action and rapid response, effectively matching the automated production cycle.

[0049] Specifically, in this embodiment, the mounting base 21 is mounted on the outer side of one side of the housing 1 in the longitudinal direction; the pickup part 22 is mounted on the side of the mounting base 21 opposite to the housing 1.

[0050] Thus, the mounting base 21 is positioned on the outer side of one longitudinal side of the housing 1, i.e., outside the main body of the housing 1, rather than inside the cavity. This simplifies the structure, facilitates installation and maintenance, and reduces the space occupied inside the housing 1. The mounting base 21 is fixed to the outer wall of the housing 1 by fasteners or snap-fit. It must have sufficient strength to bear the moving load of the pickup unit 22. The material can be aluminum alloy, stainless steel, or high-strength engineering plastic. Of course, other possible materials can also be used, depending on the actual working conditions. This specification does not limit this aspect.

[0051] The pickup unit 22 is installed on the side of the mounting base 21 away from the housing 1, so that its working side faces the external operating area. This helps to expand the lateral operating space and avoids interference with the housing 1 or other equipment. This layout allows the pickup unit 22 to directly connect to the loading and unloading stations, improving operating efficiency.

[0052] The lateral movement of the pickup unit 22 is driven by a horizontal drive device. The drive method can be a cylinder, a servo motor with a synchronous belt or a lead screw structure. This manual does not limit its specific form. It can be a cam, a connecting rod or other linear drive method, which will not be described in detail here.

[0053] This configuration, with the mounting base 21 located on the outside of the housing 1 and the pickup unit 22 positioned away from the housing 1, shortens the transmission path, improves response accuracy, and facilitates equipment installation, debugging, and maintenance. Furthermore, the external structure avoids interference with other components of the production line, ensuring smooth pickup and placement operations.

[0054] Specifically, in this embodiment, the picking and placing mechanism 2 further includes a first driving mechanism 23 and a second driving mechanism 24. The first driving mechanism 23 has a first driving part 231 that is movably arranged in the vertical direction, and the first driving part 231 is fixedly connected to the mounting base 21. The second driving mechanism 24 is mounted on the mounting base 21, and the second driving mechanism 24 has a second driving part 25 that is movably arranged in the horizontal direction, and the second driving part 25 is connected to the picking part 22 to drive the picking part 22 to move.

[0055] It is understood that the first drive unit 231 is fixedly connected to the mounting base 21, directly driving the mounting base 21 to rise and fall. The first drive mechanism 23 can be a cylinder, an electric push rod, a servo motor with a lead screw, a cam, or a linkage mechanism, etc. This specification does not limit its specific structure; it can be a linear motor or other linear drive form, which will not be described in detail here.

[0056] The second drive mechanism 24 is mounted on the mounting base 21 and is used to drive the pickup unit 22 to move laterally. It has a horizontally movable second drive unit 25, which is connected to the pickup unit 22 to achieve lateral transfer. The second drive mechanism 24 can be a synchronous belt driven by a stepper motor or servo motor, a ball screw, a linear cylinder, or a swing arm mechanism, etc. Other possible drive methods can also be used, depending on the stroke, speed, and accuracy requirements. This specification does not limit this aspect. Its installation position should ensure smooth movement of the pickup unit 22, avoiding uneven loading or jamming.

[0057] By setting up independent first drive mechanism 23 and second drive mechanism 24, the vertical lifting and horizontal conveying actions are controlled respectively, achieving motion decoupling and improving control accuracy and response speed. This drive structure has a compact layout, reliable operation, and is easy to link with automation systems, meeting the requirements of rhythmic and continuous production line operations, while also facilitating maintenance and debugging.

[0058] Specifically, in this embodiment, the first drive mechanism 23 further includes a first motor 232 and a transmission structure. The first motor 232 is fixedly installed inside the housing 1 and has a first rotating shaft extending laterally. The transmission structure includes two transmission wheels 233 and a transmission belt 234 wrapped around the periphery of the two transmission wheels 233. The two transmission wheels 233 are arranged at intervals in the vertical direction. One of the transmission wheels 233 is coaxially connected to the first rotating shaft and is connected to the other transmission wheel 233 through the transmission belt 234. The first drive part 231 is provided on the transmission belt 234.

[0059] The first motor 232 is fixedly installed inside the housing 1. Its output end is provided with a first rotating shaft extending laterally. This motor can be a stepper motor, a servo motor, or a DC motor, and has speed regulation and precise positioning functions to provide stable power output. The first rotating shaft is arranged in a horizontal direction, and its two ends or one end are connected to a transmission wheel 233 in the transmission structure to realize power transmission.

[0060] The transmission structure consists of two transmission wheels 233 and a transmission belt 234. The two transmission wheels 233 are spaced apart vertically and are respectively installed in the upper and lower support positions within the housing 1, forming a vertical transmission path. One transmission wheel 233 is coaxially connected to the first shaft of the first motor 232, serving as the driving wheel, while the other transmission wheel 233 serves as the driven wheel. The two are synchronously driven by the transmission belt 234 surrounding them. The transmission belt 234 can be a flexible transmission element with tensile strength, such as a synchronous belt, roller chain, or steel belt, ensuring no slippage and accurate positioning during transmission.

[0061] A first drive unit 231 is fixedly installed on the transmission belt 234. The first drive unit 231 can be a connecting plate, a clamping block or an attachment, and is directly connected to the mounting base 21. When the transmission belt 234 rotates with the motor, it drives the first drive unit 231 and the mounting base 21 to reciprocate in the up and down direction.

[0062] The wheel structure, pitch, and material of the transmission wheel 233 can be selected according to the load and operating speed. Of course, other possible shapes can also be used. The specific design can be determined according to the actual situation, and this specification does not limit this aspect. The mounting direction of the first motor 232 and the layout of the transmission wheel 233 can be flexibly adjusted according to the internal space of the housing 1. This specification does not limit the specific mounting form. Alternative solutions such as cam drive, linkage drive, and lead screw structure can be used, which will not be described in detail here.

[0063] The lifting and lowering drive of the mounting base 21 is achieved by using a motor in conjunction with a transmission wheel 233 and a transmission belt 234. This method features smooth transmission, low operating noise, and easy maintenance. Furthermore, precise control of the lifting speed and position of the mounting base 21 can be achieved by controlling the motor speed and rotation angle, meeting the requirements of automated cycle time. This transmission method has a compact structure and occupies little space.

[0064] Furthermore, in this embodiment, a first guide portion 3 is provided on the opening a side of the housing 1, and the first guide portion 3 extends vertically; a guide groove 21a is provided on the side of the mounting base 21 facing the first guide portion 3, and the mounting base 21 slides with the first guide portion 3 through the guide groove 21a.

[0065] Understandably, the first guide section 3 extends vertically and serves as a guide reference for the lifting and lowering movement of the mounting base 21. The first guide section 3 can be a guide rail 32, a guide post 26, a rib, or a sliding rod structure. Its cross-sectional shape can be rectangular, dovetail, T-shaped, or cylindrical, etc., and it can form a sliding fit with the guide groove 21a on the mounting base 21 to ensure that the mounting base 21 maintains a stable posture during lifting and lowering, and prevents deflection or shaking.

[0066] The first guide part 3 is fixed to the inner or outer side wall of the housing 1 by welding, screwing or snapping, and its length covers the entire lifting stroke of the mounting base 21 to ensure the continuity and effectiveness of the guiding function.

[0067] The mounting base 21 has a guide groove 21a on the side facing the first guide part 3. This guide groove 21a forms a sliding pair with the first guide part 3 in the assembled state, enabling precise vertical guidance of the mounting base 21. The inner contour of the guide groove 21a matches the outer contour of the first guide part 3 and can be designed as a through groove or a semi-enclosed structure for easy assembly and maintenance. The guide groove 21a can be equipped with friction-reducing elements such as rollers 4, sliders, or built-in bearings to reduce frictional resistance and improve smoothness of movement.

[0068] The clearance between the guide groove 21a and the first guide part 3 needs to be controlled within a reasonable range to ensure both the flexibility of movement and to avoid excessive looseness that could affect the positioning accuracy.

[0069] By providing a first guide portion 3 extending vertically on the opening a side of the housing 1, and configuring a guide groove 21a that slides with it on the mounting base 21, a stable and reliable guide structure is formed, which can effectively constrain the lifting and lowering trajectory of the mounting base 21 and prevent it from swaying, tilting or rotating during operation.

[0070] Specifically, in this embodiment, the first guide portion 3 includes two first guide bars 31 spaced apart in the horizontal direction and extending upward in the vertical direction, the two first guide bars 31 being disposed on both sides of the opening a; the guide groove 21a includes two first grooves spaced apart in the horizontal direction and extending upward in the vertical direction, each first groove being slidably engaged with a corresponding first guide bar 31.

[0071] The first guide section 3 includes two first guide bars 31, which are respectively disposed on both sides of the opening a, forming a symmetrical or quasi-symmetrical guide structure. It should be noted that each first guide bar 31 can be a raised structure with a rectangular, trapezoidal or arc-shaped cross-section, and its extension length covers the entire vertical stroke of the mounting base 21, ensuring effective guidance throughout the entire stroke range.

[0072] The first guide bar 31 can be fixed to the side wall of the housing 1 by screw fastening, welding or embedding. The material can be metal or high-strength engineering plastic, with sufficient rigidity and wear resistance. Of course, other possible shapes can also be used. The specific shape can be determined according to the actual situation. This specification does not limit this embodiment.

[0073] Thus, the dual guide bar structure can effectively improve the support stability of the mounting base 21 and prevent it from torsional deformation or excessive force on one side during lifting.

[0074] The guide groove 21a is provided with two first grooves that are spaced apart in the horizontal direction and extend in the vertical direction. The position of each first groove corresponds to the first guide strip 31 on both sides of the opening a. During assembly, each first groove is fitted onto the outer periphery of the corresponding first guide strip 31 to form a sliding fit pair.

[0075] Understandably, the first groove can be a through-hole channel or a U-shaped groove structure, with its inner wall maintaining an appropriate clearance with the surface of the first guide strip 31, ensuring smooth sliding while restricting the degree of freedom of the mounting base 21 in the lateral and rotational directions. A sliding bearing, self-lubricating bushing, or roller assembly can be installed within the first groove to reduce the coefficient of friction and improve motion stability.

[0076] By setting two first guide bars 31 spaced apart in the horizontal direction and configuring two corresponding first grooves on the mounting base 21 to achieve sliding fit, a double-point symmetrical guide structure is formed, which significantly improves the stability and anti-torsion ability of the lifting movement of the mounting base 21, effectively suppresses the shaking or jamming caused by off-center load, and improves the repeatability and reliability of the picking and placing action.

[0077] Specifically, in this embodiment, the second driving part 25 includes a connecting seat 251, and a guide structure is provided between the connecting seat 251 and the mounting seat 21. The guide structure is used to guide the connecting seat 251 when it slides laterally relative to the mounting seat 21.

[0078] Understandably, the connecting seat 251 of the second drive unit 25 serves as a transitional component between the second drive mechanism 24 and the pickup unit 22, transmitting driving force and maintaining smooth movement. A guide structure is provided between the connecting seat 251 and the mounting base 21. This guide structure provides precise motion guidance when the connecting seat 251 slides laterally relative to the mounting base 21, ensuring that the pickup unit 22 maintains a stable posture during the transfer stroke and preventing deflection or jamming.

[0079] The connecting seat 251 is fixedly connected to the pickup part 22 by fasteners or integral molding. Its structural shape can be designed as an L-shaped, T-shaped, or plate-like structure according to the spatial layout. The material can be lightweight high-strength metal or engineering plastic to reduce the moment of inertia. The guide rail 32 or guide post in the guide structure is fixed to the mounting seat 21, and the slider or sliding part is fixed to the connecting seat 251, or vice versa. The specific installation method can be flexibly selected according to the assembly process and stress conditions. This specification does not limit the specific form of the guide structure. It can be a cam groove guide, a linkage limiting structure, or other mechanical structures that can achieve lateral guidance function, which will not be described in detail here.

[0080] By setting a guide structure between the connecting seat 251 and the mounting seat 21, the trajectory of the connecting seat 251 during the lateral movement can be well constrained, thereby improving the stability and guiding accuracy of the picking unit 22's transfer action and preventing shaking, tilting or jamming caused by uneven load or driving force.

[0081] Specifically, in this embodiment, the guide structure includes a guide post 26 and a guide hole 251a that extends laterally on the connecting seat 251. The guide post 26 extends laterally and passes through the guide hole 251a.

[0082] The guide post 26 is fixed to the mounting base 21 in the transverse direction, and its axis is consistent with the transverse movement direction, serving as a guide reference for the sliding of the connecting base 251.

[0083] The guide post 26 can be cylindrical or square, made of metal, and has sufficient rigidity and surface finish. It can be reliably installed by thread, interference fit or end fasteners.

[0084] A guide hole 251a is provided on the connecting seat 251, extending laterally and slidingly engaging with the guide post 26. A self-lubricating bushing or linear bearing can be embedded within the guide hole 251a to reduce friction, improve smoothness of movement, and enhance wear resistance. The guide post 26 passes through the guide hole 251a, providing stable guidance when the connecting seat 251 moves, restricting its degrees of freedom in non-lateral directions, and ensuring accurate movement trajectory. This structure is simple and compact, easy to assemble, and suitable for space-constrained applications. Of course, other possible shapes can also be used; the specific design can be determined according to the actual situation, and this specification does not limit this embodiment.

[0085] Specifically, in this embodiment, the guide structure further includes a guide rail 32 and a slide groove 251b respectively disposed on the mounting base 21 and the connecting base 251. The guide rail 32 extends laterally, and the slide groove 251b slides in cooperation with the guide rail 32.

[0086] Understandably, the guide rail 32 extends laterally and is fixed to either the mounting base 21 or the connecting base 251. Its cross-section can be rectangular, T-shaped, dovetail-shaped, or arc-shaped. A groove 251b is provided on another component, its inner contour matching that of the guide rail 32, forming a sliding fit pair. When the second drive mechanism 24 moves the connecting base 251, the guide rail 32 slides within the groove 251b, restricting its degree of freedom in the non-moving direction and ensuring smooth and accurate lateral movement.

[0087] It should be noted that the guide structure can be arranged in a single set or two sets can be symmetrically set on both sides of the lateral direction to form a double guide structure.

[0088] Of course, other possible shapes can also be used, and the specific shape can be determined according to the actual situation. This specification does not limit this embodiment. This specification does not limit the specific material combination or installation method of the guide rail 32 and the slide groove 251b. It can be a cam groove, a connecting rod limiter, or other structures that achieve linear guidance, which will not be described in detail here.

[0089] Specifically, in this embodiment, the picking-up part 22 includes two clamping arms 221, which are movably arranged in directions of approaching and moving away from each other, for clamping the handle 201 on the top of the bucket lid 200 during the approaching stroke; the sides of the two clamping arms 221 that approach each other are configured to be adapted to the peripheral side of the handle 201 of the bucket lid 200.

[0090] The picking unit 22 includes two clamping arms 221, which can move towards or away from each other. Approaching the clamping arms clamps the handle 201 on the top of the lid 200, while moving them away releases them. The opening and closing of the clamping arms 221 is controlled by a drive mechanism, which can be a cylinder, a motor with gear and rack, a cam, or a linkage mechanism, etc., enabling synchronous or symmetrical movement. This specification does not limit the specific structure; it can be a cam shaft drive, a lead screw structure, or other feasible solutions, which will not be described in detail here. The movement path of the clamping arms 221 can be linear, rotary, or arc-shaped, and can be flexibly designed according to the installation space and operational requirements.

[0091] The opposing side profiles of the two clamping arms 221 are adapted to the peripheral side surfaces of the handle 201 of the bucket lid 200, for example, designed as curved, flat, or chamfered surfaces, to increase the contact area, improve clamping stability, and prevent slippage. The clamping surfaces may be provided with anti-slip textures or an elastic material layer to further enhance friction and prevent damage to the bucket lid 200. The clamping arm 221 body is made of metal or high-strength plastic to ensure structural strength and lightweight design. The opening and closing stroke and clamping force can be adjusted according to actual needs; other possible shapes can also be used, specifically adapted to different handle 201 structures. This specification does not limit this aspect.

[0092] By setting two movable gripping arms 221 with gripping surfaces adapted to the shape of the handle 201, stable gripping and reliable release of the handle 201 of the bucket lid 200 are achieved, ensuring firm gripping and accurate positioning, effectively preventing slippage or displacement. At the same time, it is compatible with bucket lids 200 of various handle 201 forms, improving the versatility of the bucket lid picking and placing device 100 and the stability of automated operation.

[0093] Furthermore, in this embodiment, the bottom of the housing 1 is also provided with rollers 4 for moving and positioning the entire device.

[0094] The number of rollers 4 can be multiple, distributed around the bottom surface of the housing 1 or at the four corners, to ensure balanced force distribution during load-bearing. Each roller 4 is mounted to the bottom of the housing 1 via a bracket or bushing structure, and can be in the form of omnidirectional wheels or directional wheels. Omnidirectional wheels facilitate flexible movement in multiple directions, while directional wheels help maintain stability during movement.

[0095] This manual does not limit the specific structural form of the roller 4. It can be a suspension buffer wheel, a height-adjustable and retractable wheel set, or other auxiliary movement structure, which will not be described in detail here.

[0096] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and 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.
