Description

Technical Field

[0001] This invention relates to the field of pharmaceutical equipment, and more specifically to an automatic syringe dispensing device. Background Technology

[0002] In the pharmaceutical equipment field, syringes are typically packaged using honeycomb containers (hereinafter referred to as honeycomb trays), with multiple honeycomb trays then placed inside a box for storage and transportation. As the pharmaceutical industry continues to increase its level of automation, higher demands are being placed on automated syringe feeding equipment.

[0003] Existing automated syringe feeding processes typically involve the following steps: removing the tray from the syringe box, extracting the syringes from the tray, adjusting the syringe spacing to match the process requirements of downstream equipment, and finally conveying the syringes to the downstream equipment. In this process, because the syringes are initially packaged using trays, the spacing between the syringes is small and fixed, while downstream equipment usually requires a larger spacing. This necessitates spacing adjustment after the syringes are removed. Furthermore, the need to constantly replace trays and boxes can easily cause interruptions in syringe delivery.

[0004] Currently, existing technologies have the following shortcomings: taking out syringes and adjusting the syringe spacing usually require separate mechanisms, resulting in complex equipment structures and large space occupation; the process of changing the nesting board and box will cause a pause in syringe delivery, making it difficult to meet the downstream equipment's demand for continuous syringe supply; and there is a lack of effective transition mechanisms in the process of syringes being taken out of the nesting board and delivered to downstream equipment, which affects production efficiency.

[0005] Therefore, how to design an automated device that can efficiently complete syringe extraction, spacing adjustment, and ensure continuous feeding of downstream equipment is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0034] The invention is described more specifically by way of example in the following paragraphs with reference to the accompanying drawings. The advantages and features of the invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the invention.

[0035] This embodiment provides an automatic syringe dispensing device. Please refer to [reference needed]. Figures 1-2 ,include:

[0036] The frame body 1 is equipped with a material conveying system and a syringe dispensing system.

[0037] The material conveying system includes a feeding device 2, a nest board separation device 3 and a nest board transfer device 4. The syringe extraction system includes a syringe extraction device 6 and a syringe conveying device 7. The syringe extraction device 6 is used to extract syringes from nest board B that has been transferred to the syringe extraction station by the nest board transfer device 4.

[0038] The feeding device 2 includes a conveyor line for conveying nest boxes A, the nest board separation device 3 is used to separate nest boards B from the nest boxes A of the feeding device 2, and the nest board transfer device 4 is used to transfer the nest boards B separated by the nest board separation device 3 to the syringe dispensing station.

[0039] The syringe picking device 6 includes a support rotating shaft and a variable distance assembly. The variable distance assembly is mounted on the frame body 1 via the support rotating shaft to grip the syringes on the nest plate transfer device 4. The support rotating shaft is used to switch the syringe picking and placing positions. The syringe conveying device 7 is used to receive and convey the syringes placed by the variable distance assembly at the syringe placing position.

[0040] Specifically, the frame body 1 is the base of the entire equipment, on which the material conveying system and syringe dispensing system are installed. The material conveying system is responsible for processing nest boxes A and transporting them to designated workstations for further processing. Specifically, it consists of the following parts: Feeding device 2 – This device transports nest boxes A to subsequent processing steps. Nest box separation device 3 – When nest box A arrives at feeding device 2, this device separates individual nest boxes B for further processing. Nest box transfer device 4 – Once individual nest boxes B are separated, this device transports them to the syringe dispensing station, ready for the next step of the operation.

[0041] The function of the syringe retrieval system is to retrieve syringes from the nesting plate B. It mainly consists of two parts: a syringe retrieval device 6, located at the syringe retrieval station, responsible for retrieving syringes from nesting plate B. It features adjustable syringe spacing and a syringe retrieval / placement position switching function. A syringe transport device 7 receives the syringes retrieved from the syringe retrieval device 6 and transports them to the next destination. The core components of the syringe retrieval device 6 include a support shaft and a pitch-adjusting assembly. The support shaft switches between different positions to achieve the syringe retrieval / placement function; the pitch-adjusting assembly grips each group of syringes in the nesting plate and adjusts the distance between each syringe.

[0042] The automatic syringe dispensing equipment achieves efficient processing of nest box A and accurate dispensing of syringes through its reasonable structure and design, thereby improving production efficiency and automation.

[0043] Preferably, the nest board transfer device 4 includes a fixed base, a connecting shaft, and a sliding member. The two ends of the connecting shaft are fixed on the fixed base, and the sliding member is sleeved on the connecting shaft and can slide along the connecting shaft. The sliding member has a bearing portion on the side near the feeding device 2.

[0044] Specifically, the fixing seat is a fundamental part of the nest board transfer device 4, used to fix the two ends of the connecting shaft. The fixing seat is typically fixed to the frame body 1, providing a stable support point for the connecting shaft. The connecting shaft is a key component in the nest board transfer device 4 used to support the sliding member. Both ends of the connecting shaft are fixed to the fixing seat, allowing the sliding member to slide along the length of the connecting shaft. The sliding member is a component sleeved on the connecting shaft, allowing it to slide freely along the shaft. The design of the sliding member enables it to move smoothly on the connecting shaft, thereby realizing the transfer of the nest board B.

[0045] When nest box A is conveyed from feeding device 2 to the carrier section, the sliding member moves along the connecting shaft under the action of the drive device (such as a cylinder or motor), transferring nest plate B from feeding device 2 to the station of the syringe dispensing system. This design makes the transfer of nest plate B more flexible and precise, and also facilitates automated control.

[0046] Preferably, the material conveying system further includes a nesting board positioning device 5, which is placed on the bearing part to position and shape the nesting board B.

[0047] The main function of the nest plate positioning device 5 is to precisely position the nest plate B after it has been transferred to the syringe dispensing station. The positioning device adjusts the position of the nest plate B to ensure that the syringes on the nest plate B correspond to the position of the syringe dispensing device 6, thereby improving the accuracy and efficiency of syringe dispensing. The nest plate positioning device 5 is located on the support unit, meaning it is part of the sliding component, which is close to or directly opposite the syringe dispensing station. When the sliding component transfers the nest plate B from the feeding device 2 to the syringe dispensing station, the positioning device fine-tunes the nest plate B to ensure it is in the correct position.

[0048] Preferably, the nesting plate B is made of soft plastic. To ensure accurate removal of the subsequent syringe C, a nesting plate positioning device 5 is provided on the support part of the nesting plate transfer device. The nesting plate positioning device 5 includes a support base plate and multiple clamping components. The support base plate has a support plane adapted to the shape of the nesting plate B for supporting the nesting plate B. The clamping components are evenly arranged along the edge of the nesting plate B. Each clamping component includes a clamping cylinder and a clamping head. The clamping cylinder drives the clamping head to clamp the edge of the nesting plate B, thereby achieving positioning and shape correction of the nesting plate B. Through the action of the nesting plate positioning device 5, the nesting plate B is ensured to maintain a standard flat shape, effectively avoiding positional deviations during the subsequent removal of the syringe C due to deformation of the nesting plate B.

[0049] Precise positioning reduces errors during needle retrieval, ensuring each syringe is accurately removed. Positioned nesting plate B can be processed more quickly by the syringe retrieval device 6, reducing downtime or adjustment time caused by inaccurate positioning. Stable positioning of nesting plate B contributes to the smooth operation of the entire material conveying system, reducing equipment malfunctions caused by nesting plate B movement or offset.

[0050] Furthermore, the feeding device 2 includes a conveyor belt disposed on the frame body 1, and parallel guide plates are provided on both sides of the conveyor belt, forming a conveying channel for accommodating the nest box A between the guide plates and the conveyor belt.

[0051] Specifically, in the feeding device 2 of the automatic syringe dispensing equipment, the conveyor belt is the core component, mounted on the frame body 1. The conveyor belt's function is to transport the nest box A along a preset path for subsequent processing. Guide plates are located on both sides of the conveyor belt and are set parallel to it. The main function of the guide plates is to guide the nest box A to move correctly on the conveyor belt, preventing it from shifting laterally or tipping over during transport. The space between the guide plates and the conveyor belt forms a transport channel specifically designed to accommodate the nest box A. The design of the transport channel ensures the stability of the nest box A during transport while also limiting its range of movement, preventing it from deviating from the predetermined transport path.

[0052] Through the cooperation of the conveyor belt and guide plate, the feeding device 2 can continuously and stably transport the nest box A to the next processing stage, namely the nest board separation device 3. This design improves the automation and reliability of the conveying process, reduces the need for manual intervention, and also improves the overall efficiency of the production line.

[0053] Furthermore, the nest board separation device 3 includes a bracket, the top of which is provided with a lifting drive mechanism, the lifting drive mechanism being connected to a clamping assembly for clamping the nest board B, and the bracket being rotatably connected to the frame body via a bearing seat.

[0054] Specifically, the support frame is the basic structure of the nest board separation device 3, providing support for the entire device. The support frame is fixed to the frame body 1, providing a stable mounting platform for other components. A vertical lifting cylinder is mounted on top of the support frame. This cylinder provides power, enabling the clamping assembly to move vertically, thereby clamping and releasing the nest board B. The clamping assembly is connected to the vertical lifting cylinder and is the component used for direct contact and operation of the nest board B. The clamping assembly is designed to firmly clamp the nest board B while releasing it when needed.

[0055] When nest box A is conveyed to nest board separation device 3 via conveyor belt, the vertical lifting cylinder drives the clamping assembly to move downwards, clamping nest board B. Once nest board B is clamped, the vertical lifting cylinder can further operate the clamping assembly to separate nest board B from nest box A. The separated individual nest board B can then be transferred to the syringe retrieval station for the next syringe retrieval operation.

[0056] For further details, please refer to... Figure 3 The syringe dispensing device 6 further includes:

[0057] A connecting plate is fixedly connected to the other end of the supporting rotating shaft. The two ends of the connecting plate are respectively provided with pitch-changing components for adjusting the syringe spacing.

[0058] The first drive mechanism 61 is fixed to the connecting plate and is connected to the pitch component for transmission.

[0059] Specifically, the support shaft is one of the key components of the syringe dispensing device 6. One end of it is fixed to the frame body 1, providing support for the entire device. The design of the support shaft allows it to withstand a certain load and rotate when needed, enabling the dispensing of a bottle at one end and the placement of the bottle at the other. The connecting plate is fixedly connected to the other end of the support shaft, acting as a bridge connecting the support shaft and the pitch-changing assembly. Pitch-changing assemblies are located at both ends of the connecting plate, meaning that the connecting plate needs to be sufficiently robust and stable to ensure the accurate operation of the pitch-changing assemblies.

[0060] The main function of the variable-distance assembly is to adjust the distance between the syringe dispensing device and the nesting plate positioning device. By adjusting this distance, the variable-distance assembly ensures that the syringe dispensing device 6 can accurately remove the syringe C from the nesting plate B.

[0061] The first drive mechanism 61 is fixed to the connecting plate and is connected to the pitch-changing assembly. The function of this drive mechanism is to provide power to drive the pitch-changing assembly to adjust the pitch. The syringe dispensing device 6 achieves precise syringe dispensing and placement through the coordinated operation of the supporting shaft, connecting plate, pitch-changing assembly, and first drive mechanism 61. After the nesting plate B is transferred to the syringe dispensing station, the supporting shaft can rotate to a suitable position under the action of the first drive mechanism 61, the pitch-changing assembly adjusts the pitch, and then the syringe dispensing device 6 can remove the syringe from the nesting plate B and transport the syringe C to the next station via the syringe conveying device 7.

[0062] Furthermore, the pitch control assembly includes a mounting plate 62 and a pitch control pull plate 67;

[0063] One end of the mounting plate 62 is fixed to the first driving mechanism 61, and the other end is provided with a needle-taking assembly. The first driving mechanism 61 is connected to the mounting plate 62 and drives the mounting plate 62 to extend and retract.

[0064] One end of the variable pitch pull plate 67 is placed on the mounting plate 62 through the second drive mechanism 63, and the variable pitch pull plate 67 is moved telescopically by the second drive mechanism 63. The other end of the variable pitch pull plate 67 is provided with a plurality of receiving slots that are adapted to the syringe C.

[0065] Specifically, the mounting plate 62 is a component of the variable pitch assembly, with one end fixed to the first drive mechanism 61. The other end of the mounting plate 62 is equipped with a needle-retrieving assembly, which directly participates in the needle-retrieval operation. The first drive mechanism 61 is drively connected to the mounting plate 62, enabling it to move telescopically. This movement is to adjust the position of the needle-retrieval assembly to facilitate the removal of the syringe C from the housing plate B. The needle-retrieval assembly is mounted on the mounting plate 62 and is designed to grasp and remove the syringe. When the mounting plate 62 moves under the drive of the first drive mechanism 61, the needle-retrieval assembly also moves accordingly, thereby realizing the syringe pick-up and drop operation.

[0066] The pitch-adjustable pull plate 67 is another key component in the pitch-adjustable assembly. One end of the pull plate 67 is mounted on the mounting plate 62 via the second drive mechanism 63. The pitch-adjustable pull plate 67 can be telescopically moved via the second drive mechanism 63, and this movement is used to adjust the spacing between the syringes C.

[0067] The variable pitch assembly, through the cooperation of the mounting plate 62 and the variable pitch pull plate 67, and the coordinated operation of the first drive mechanism 61 and the second drive mechanism 63, achieves precise adjustment of the syringe spacing and stable syringe placement and removal. When it is necessary to adjust the syringe C spacing, the first drive mechanism 61 and the second drive mechanism 63 respectively drive the mounting plate 62 and the variable pitch pull plate 67, so that the needle removal assembly can adapt to syringes C with different spacings.

[0068] Preferably, the first drive mechanism 61 and the second drive mechanism 63 are telescopic cylinders. It is understood that the first drive mechanism 61 can also be a motor, a cylinder or other suitable drive device, and the second drive mechanism 63 can be an independent motor, a cylinder or other type of drive device, which works according to the control signal to achieve precise control of the variable pitch plate 67.

[0069] Furthermore, the needle retrieval assembly includes a sliding shaft 64 and multiple sliding seats 66. The sliding shaft 64 is fixed on the mounting plate 62, and the sliding seats 66 are sleeved on the sliding shaft 64 through bearings 65. Each sliding seat 66 has a needle retrieval head 68 at one end, and the needle retrieval head 68 has a suction nozzle inside.

[0070] Specifically, the sliding shaft 64 is the fixed part of the needle retrieval assembly, fixed to the mounting plate 62. The function of the sliding shaft 64 is to provide an axis, allowing the sliding seat 66 to slide along the shaft, thereby achieving the positioning and movement of the syringe head 68. The sliding seat 66 is sleeved on the sliding shaft 64 via a bearing 65, a design that allows the sliding seat 66 to move flexibly along the sliding shaft 64. Each sliding seat 66 has a syringe head 68 mounted at one end, allowing multiple sliding seats 66 to perform needle retrieval operations simultaneously, improving needle retrieval efficiency. The syringe head 68 is the part that directly contacts the syringe C, and it is mounted at one end of the sliding seat 66. The design of the syringe head 68 needs to ensure that it can firmly grasp the syringe C for removal from the tray B. The syringe head 68 has a suction nozzle, a common needle retrieval mechanism that uses vacuum suction to draw up the syringe C. The suction nozzle effectively adsorbs the syringe and removes it from the tray B by generating negative pressure.

[0071] Furthermore, the syringe delivery device 7 includes a first conveyor belt 72 and a second conveyor belt 73 arranged in two layers, with the first conveyor belt 72 and the second conveyor belt 73 having different operating speeds.

[0072] The syringe delivery device 7 employs a double-layered conveyor belt arrangement, namely a first conveyor belt 72 and a second conveyor belt 73. This double-layered layout effectively utilizes space, improves delivery efficiency, and allows syringes C to be assigned to different delivery paths as needed. The first conveyor belt 72 and the second conveyor belt 73 operate at different speeds. This design allows syringes C to be delivered at different speeds at different stages. For example, the first conveyor belt 72 may deliver syringes C from the needle-picking assembly to the next processing stage at a faster speed, while the second conveyor belt 73 may be used at a slower speed for fine positioning adjustments or for buffering.

[0073] When the operating speeds of upstream or downstream equipment are inconsistent, the flow rate can be adjusted by using different conveyor speeds, thus acting as a buffer. This double-layer conveyor belt design improves the flexibility and adaptability of the equipment, enabling it to meet the needs of different production stages.

[0074] Furthermore, both the first conveyor belt 72 and the second conveyor belt 73 are provided with conveyor blocks 71, which are used to transport the removed syringes C.

[0075] Specifically, the conveyor block 71 is an assembly mounted on the conveyor belt for direct contact with and fixation of the syringes, ensuring their stability during transport. The primary function of the conveyor block 71 is to transport the syringes C removed by the syringe-retrieving device 6. They typically have grooves or clamps tailored to the shape and size of the syringe C, ensuring it does not fall off or tip over during transport. The conveyor block 71 also helps position the syringe C, ensuring it maintains the correct orientation and position during transport, which is crucial for subsequent automated processing steps. The conveyor block 71 also protects the syringe C from damage during transport.

[0076] After the syringes C are removed by the syringe dispensing device 6, they are placed on a conveyor block 71 on the first conveyor belt 72 or the second conveyor belt 73. The conveyor block 71 moves with the conveyor belt, transporting the syringes C from one location to another, such as from the syringe dispensing area to the packaging area or assembly area. Because the first conveyor belt 72 and the second conveyor belt 73 operate at different speeds, the design of the conveyor block 71 needs to be able to adapt to different speeds to ensure that the syringes C remain stable during high-speed or low-speed movement.

[0077] Furthermore, a collection device 9 is provided at the end of the conveyor line.

[0078] Specifically, after the syringe C is removed from the nesting plate B by the needle removal assembly, the nesting plate separation device 3 will place the empty nesting plate back onto the conveyor line. Due to the inclined design of the conveyor line, i.e., the presence of a ramp 8, the empty nesting plate will move along the conveyor line into the collection device 9. By collecting the empty nesting plates, they can be easily reintroduced into the production process, reducing material waste and improving resource utilization.

[0079] In summary, by setting up a material conveying system and a syringe picking system, wherein the material conveying system includes a feeding device, a nesting board separation device, and a nesting board transfer device, and the syringe picking system includes a syringe picking device with variable pitch function and a double-layered syringe conveying device, automatic separation of nesting boards, automatic syringe picking, and pitch adjustment are achieved. Furthermore, by operating the double-layered conveyor belts at different speeds, the demand for continuous syringe supply from downstream equipment is met, thereby improving production efficiency.

[0080] The above examples illustrate the present invention only to aid in understanding it and are not intended to limit the scope of the invention. Those skilled in the art can make various simple deductions, modifications, or substitutions based on the principles of this invention.
