Description

[0002] In the field of pharmaceutical equipment, syringes are usually packaged in honeycomb containers (hereinafter referred to as honeycomb plates), and multiple honeycomb plates are placed in boxes for storage and transportation. With the continuous improvement of the automation level of the pharmaceutical industry, higher requirements are placed on automatic syringe feeding equipment.

[0003] The existing automatic syringe loading process usually requires the following steps: taking out the nest plate in the syringe box, taking out the syringe from the nest plate, adjusting the syringe spacing to match the process requirements of the downstream equipment, and finally delivering the syringe to the downstream equipment. In this process, since the syringes are initially packaged in a nested manner, the spacing between the syringes is small and fixed, while the downstream equipment usually requires a larger syringe spacing, which requires spacing adjustment after the syringes are taken out. At the same time, the need to constantly replace the nest plate and box easily causes interruptions in the delivery of the syringes.

[0004] At present, the existing technology has the following shortcomings: taking out the syringe and adjusting the syringe spacing usually require independent mechanisms to complete, the equipment structure is complex, and the space occupied is large; since the process of replacing the nest plate and the box will cause the suspension of syringe delivery, it is difficult to meet the downstream equipment's demand for continuous supply of syringes; there is a lack of effective transition mechanism in the process from the syringe being taken out of the nest plate to being transported to the downstream equipment, which affects production efficiency.

It should be noted that the accompanying drawings are in very simplified form and are not in exact proportions, and are only used to facilitate and clearly assist in illustrating the purpose of the embodiments of the present invention.

[0035] This embodiment provides an automatic syringe removal device, please refer to Figure 1-Figure 2 ,include:

[0036] A frame body 1, on which a material conveying system and a syringe removal system are arranged;

[0037] The material conveying system includes a feeding device 2, a nest plate separation device 3 and a nest plate transfer device 4, and the syringe taking system includes a syringe taking device 6 and a syringe conveying device 7. The syringe taking device 6 is used to take out the syringe from the nest plate B transferred to the syringe taking station by the nest plate transfer device 4;

[0038] The feeding device 2 comprises a conveying 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 removal station;

[0039] The syringe retrieval device 6 includes a supporting shaft and a pitch-changing assembly. The pitch-changing assembly is installed on the frame body 1 through the supporting shaft to clamp the syringe on the nest plate transfer device 4. The supporting shaft is used to switch the position of taking and placing the syringe, and the syringe conveying device 7 is used to receive and convey the syringe placed by the pitch-changing 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 the syringe removal system are installed. The material conveying system is responsible for processing the nest box A and transporting it to the designated station for processing. Specifically, it consists of the following parts: Feeding device 2-this device is used to transport the nest box A to the subsequent processing steps. Nest plate separation device 3-when the nest box A arrives at the feeding device 2, this device will separate the single nest plate B in it for further processing. Nest plate transfer device 4-once the single nest plate B is separated, this device will transport it to the syringe removal station to prepare for the next step of operation.

[0041] The function of the syringe retrieval system is to retrieve the syringe from the nest plate B. It is mainly composed of the following two parts: the syringe retrieval device 6 is located at the syringe retrieval station and is responsible for retrieval of the syringe from the nest plate B. It has an adjustable syringe spacing function and a switching function for taking and placing syringes. The syringe conveying device 7 is responsible for receiving the syringes taken out from the syringe retrieval device 6 and transporting them to the next destination. The core components of the syringe retrieval device 6 include a supporting shaft and a variable pitch assembly. Among them, the function of the supporting shaft is to switch between different positions to realize the function of taking and placing syringes; the variable pitch assembly can clamp each group of syringes in the nest plate and adjust the distance between each syringe.

[0042] The automatic syringe removal device realizes efficient processing of the nest box A and accurate removal of the syringe through reasonable structure and design, thereby improving production efficiency and automation.

[0043] Preferably, the nest plate transfer device 4 includes a fixed seat, a connecting shaft and a sliding member, both ends of the connecting shaft are fixed on the fixed seat, the sliding member is sleeved on the connecting shaft and can slide along the connecting shaft, and a bearing portion is provided on the side of the sliding member close to the feeding device 2.

[0044] Specifically, the fixing seat is a basic part of the nest board transfer device 4, which is used to fix the two end points of the connecting shaft. The fixing seat is usually fixed on the frame body 1 to provide a stable support point for the connecting shaft. The connecting shaft is a key component used to support the sliding member in the nest board transfer device 4. The two ends of the connecting shaft are fixed on the fixing seat so that the sliding member can slide along the length direction of the connecting shaft. The sliding member is a component that is sleeved on the connecting shaft and can slide freely along the connecting 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 the nest box A is transported from the feeding device 2 to the carrying part, the slide moves along the connecting shaft under the action of the driving device (such as a cylinder or a motor), and the nest plate B is transferred from the feeding device 2 to the station of the syringe removal system. This design makes the transfer of the nest plate B more flexible and accurate, and also facilitates the realization of automatic control.

[0046] Preferably, the material conveying system further comprises a nest board positioning device 5, wherein the nest board positioning device 5 is placed on the bearing portion to position and shape the nest board B.

[0047] The main function of the nest plate positioning device 5 is to accurately position the nest plate B after it is transferred to the syringe retrieval station. The positioning device can adjust the position of the nest plate B to ensure that the syringe on the nest plate B corresponds to the position of the syringe retrieval device 6, thereby improving the accuracy and efficiency of needle retrieval. The nest plate positioning device 5 is placed on the bearing part, which means that it is located in a part of the slide that is close to or facing the syringe retrieval station. When the slide transfers the nest plate B from the feeding device 2 to the syringe retrieval station, the positioning device will fine-tune the nest plate B to ensure that it is in the correct position.

[0048] Preferably, the nest plate B is made of a soft plastic material. In order to ensure the accurate removal of the subsequent syringe C, a nest plate positioning device 5 is provided on the bearing portion of the nest plate transfer device. The nest plate positioning device 5 includes a supporting base plate and a plurality of clamping components. The supporting base plate is provided with a supporting plane adapted to the shape of the nest plate B, which is used to support the nest plate B. The clamping components are evenly arranged along the edge of the nest plate B. Each clamping component includes a clamping cylinder and a pressure head. The clamping cylinder drives the pressure head to clamp the edge of the nest plate B, thereby achieving the positioning and shape correction of the nest plate B. Through the action of the nest plate positioning device 5, it is ensured that the nest plate B maintains a standard flat shape, and effectively avoids position deviation during the subsequent removal of the syringe C due to deformation of the nest plate B.

[0049] Through accurate positioning, the error in the needle removal process can be reduced, ensuring that each syringe can be accurately removed. The positioned nest plate B can be processed more quickly by the syringe removal device 6, reducing downtime or adjustment time caused by inaccurate positioning. The stable positioning of the nest plate B contributes to the smooth operation of the entire material conveying system and reduces equipment failures caused by the movement or offset of the nest plate B.

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

[0051] Specifically, in the feeding device 2 of the automatic syringe removal device, the conveyor belt is the core part of the feeding device 2, which is installed on the frame body 1. The function of the conveyor belt is to convey the nest box A and move it along a preset path for subsequent processing. The guide plates are located on both sides of the conveyor belt and are arranged parallel to the conveyor belt. The main function of the guide plate is to guide the nest box A to move correctly on the conveyor belt and prevent the nest box A from shifting sideways or tipping over during transportation. The space between the guide plate and the conveyor belt forms a conveying channel, which is specifically used to accommodate the nest box A. The design of the conveying channel ensures that the nest box A remains stable during transportation, while also limiting the movement range of the nest box A so that it does not deviate from the predetermined conveying path.

[0052] Through the cooperation of the conveyor belt and the guide plate, the feeding device 2 can continuously and stably convey the nest boxes A to the next processing link, namely the nest plate 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 plate separation device 3 includes a bracket, a lifting drive mechanism is provided on the top of the bracket, the lifting drive mechanism is connected to a clamping assembly for clamping the nest plate B, and the bracket is rotatably connected to the frame body through a bearing seat.

[0054] Specifically, the bracket is the basic structure of the nest plate separation device 3, which provides support for the entire device. The bracket is fixed to the frame body 1 and provides a stable installation platform for other components. The vertical lifting cylinder is installed on the top of the bracket. The function of the cylinder is to provide power so that the clamping assembly can move in the vertical direction, thereby clamping and releasing the nest plate B. The clamping assembly is connected to the vertical lifting cylinder, and it is a component used to directly contact and operate the nest plate B. The design of the clamping assembly enables it to firmly clamp the nest plate B and release the nest plate B when needed.

[0055] When the nest box A is transported to the nest board separation device 3 by the conveyor belt, the vertical lifting cylinder will drive the clamping assembly to move downward, and the clamping assembly will clamp the nest board B. Once the nest board B is clamped, the vertical lifting cylinder can further operate the clamping assembly to separate the nest board B from the nest box A. The separated single nest board B can be transported to the syringe removal station for the next syringe removal operation.

[0056] For further information, please refer to Figure 3 , the syringe removal device 6 also includes:

[0057] A connecting plate, the connecting plate is fixedly connected to the other end of the supporting shaft, and both ends of the connecting plate are respectively provided with a variable pitch assembly for adjusting the distance between the syringes;

[0058] The first driving mechanism 61 is fixed on the connecting plate and is transmission-connected to the pitch-changing assembly.

[0059] Specifically, the support shaft is one of the key components of the syringe removal device 6, one end of which is fixed to the frame body 1 to provide support for the entire device. The design of the support shaft enables it to withstand a certain load, and it can be rotated when necessary to achieve the operation of taking a bottle at one end and putting the bottle at the other end. The connecting plate is fixedly connected to the other end of the support shaft, and it acts as a bridge, connecting the support shaft and the pitch-changing assembly. The two ends of the connecting plate are respectively provided with pitch-changing assemblies, which means that the connecting plate needs to be strong and stable enough to ensure that the pitch-changing assembly can work accurately.

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

[0061] The first driving mechanism 61 is fixed on the connecting plate and is in transmission connection with the pitch-changing assembly. The function of the driving mechanism is to provide power to drive the pitch-changing assembly to adjust the spacing. The syringe taking device 6 realizes the precise taking and placing of the syringe through the coordinated work of the supporting shaft, the connecting plate, the pitch-changing assembly and the first driving mechanism 61. After the nest plate B is transported to the syringe taking station, the supporting shaft can be rotated to a suitable position under the action of the first driving mechanism 61, the pitch-changing assembly adjusts the spacing, and then the syringe taking device 6 can take the syringe from the nest plate B, and transport the syringe C to the next station through the syringe transporting device 7.

[0062] Furthermore, the pitch-changing assembly includes a mounting plate 62 and a pitch-changing 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 removal assembly. The first driving mechanism 61 is in transmission connection with the mounting plate 62 and drives the mounting plate 62 to telescopically move.

[0064] One end of the variable-length pull plate 67 is placed on the mounting plate 62 via a second driving mechanism 63, and the variable-length pull plate 67 is driven to telescopically move by the second driving mechanism 63. The other end of the variable-length pull plate 67 is provided with a plurality of receiving grooves adapted to the syringe C.

[0065] Specifically, the mounting plate 62 is a component of the variable pitch assembly, and one end of the mounting plate 62 is fixed to the first drive mechanism 61. The other end of the mounting plate 62 is provided with a needle removal assembly, which is a component directly involved in the needle removal operation. The first drive mechanism 61 is transmission-connected to the mounting plate 62, and can drive the mounting plate 62 to telescopically move. This movement is to adjust the position of the needle removal assembly so as to facilitate the removal of the syringe C from the nest plate B. The needle removal 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 removal assembly also moves therewith, thereby realizing the operation of taking and placing the syringe.

[0066] The variable pitch pull plate 67 is another key component in the variable pitch assembly, one end of which is placed on the mounting plate 62 through the second drive mechanism 63. The variable pitch pull plate 67 can be telescopically moved by the second drive mechanism 63, and this movement is used to adjust the spacing between the syringes C.

[0067] The variable pitch assembly achieves precise adjustment of the syringe spacing and stable syringe removal through the cooperation of the mounting plate 62 and the variable pitch pull plate 67, as well as the coordinated work of the first drive mechanism 61 and the second drive mechanism 63. When the syringe C spacing needs to be adjusted, the first drive mechanism 61 and the second drive mechanism 63 drive the mounting plate 62 and the variable pitch pull plate 67 respectively, so that the needle removal assembly can adapt to syringes C with different spacings.

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

[0069] Furthermore, the needle removal assembly includes a sliding shaft 64 and a plurality of sliding seats 66, the sliding shaft 64 is fixed on the mounting plate 62, the sliding seats 66 are sleeved on the sliding shaft 64 through bearings 65, and a syringe removal head 68 is provided at one end of each of the sliding seats 66, and a suction nozzle is provided inside the syringe removal head 68.

[0070] Specifically, the sliding shaft 64 is a fixed part of the needle removal assembly, which is fixed on the mounting plate 62. The function of the sliding shaft 64 is to provide an axis so that the sliding seat 66 can slide on the axis, thereby realizing the positioning and movement of the needle removal head 68. The sliding seat 66 is sleeved on the sliding shaft 64 through the bearing 65, so that the sliding seat 66 can move flexibly on the sliding shaft 64. One end of each sliding seat 66 is equipped with a needle removal head 68, so that multiple sliding seats 66 can perform needle removal operations at the same time, thereby improving the needle removal efficiency. The needle removal head 68 is the part that directly contacts the syringe C, and it is installed at one end of the sliding seat 66. The design of the syringe removal head 68 needs to ensure that the syringe C can be firmly grasped so as to remove it from the nest plate B. A suction nozzle is provided in the syringe removal head 68, which is a common needle removal mechanism that uses vacuum suction to suck the syringe C. The suction nozzle can effectively absorb the syringe and remove it from the nest plate B by generating negative pressure.

[0071] Furthermore, the syringe conveying device 7 includes a first conveying belt 72 and a second conveying belt 73 arranged in a double layer, and the first conveying belt 72 and the second conveying belt 73 have different running speeds.

[0072] The syringe conveying device 7 adopts a conveyor belt with a double-layer arrangement of upper and lower layers, namely a first conveyor belt 72 and a second conveyor belt 73. This double-layer layout can effectively utilize space, improve conveying efficiency, and can allocate syringes C to different conveying paths as needed. The operating speeds of the first conveyor belt 72 and the second conveyor belt 73 are different. This design allows the syringe C to be conveyed at different speeds in different stages. For example, the first conveyor belt 72 may convey the syringe C from the needle removal assembly to the next processing stage at a faster speed, while the second conveyor belt 73 may perform fine position adjustment or be used for buffering at a slower speed.

[0073] When the working speed of the upstream or downstream equipment is inconsistent, the flow rate can be adjusted by different conveying speeds to play a buffering role. This double-layer conveyor belt design improves the flexibility and adaptability of the equipment and can meet the needs of different production links.

[0074] Furthermore, both the first conveyor belt 72 and the second conveyor belt 73 are provided with a conveying block 71, and the conveying block 71 is used to transport the removed syringe C.

[0075] Specifically, the conveying block 71 is a component installed on the conveyor belt, which is used to directly contact and fix the syringe so as to keep the syringe stable during the conveying process. The main function of the conveying block 71 is to transport the syringe C removed by the syringe removal device 6. They usually have grooves or clamps suitable for the shape and size of the syringe C to ensure that the syringe C does not fall off or overturn during the conveying process. The conveying block 71 can also help position the syringe C to ensure that the syringe C maintains the correct direction and position during the conveying process, which is crucial for the subsequent automated processing steps. The conveying block 71 can also protect the syringe C to prevent the syringe from being damaged during the conveying process.

[0076] After the syringes C are removed by the syringe removal device 6, they will be placed on the conveying block 71 on the first conveyor belt 72 or the second conveyor belt 73. The conveying block 71 will move with the movement of the conveyor belt to transport the syringes C from one location to another, such as from the needle removal area to the packaging area or assembly area. Since the first conveyor belt 72 and the second conveyor belt 73 have different running speeds, the design of the conveying block 71 needs to be able to adapt to different speeds to ensure that the syringes C can remain stable during high-speed or low-speed movement.

[0077] Furthermore, a collecting device 9 is provided at the end of the conveying 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 put the empty nesting plate back to the conveying line. Since the conveying line is inclined, that is, provided with a slide 8, the empty nesting plate will move along the conveying line to the collecting device 9. By collecting the empty nesting plates, they can be easily put back into the production process, reducing material waste and improving resource utilization.

[0079] In summary, by setting up a material conveying system and a syringe taking system, wherein the material conveying system includes a feeding device, a nest plate separation device and a nest plate transfer device, and the syringe taking system includes a syringe taking device with a variable pitch function and a double-layer syringe conveying device, the automatic separation of nest plates, automatic removal of syringes and spacing adjustment are realized, and by operating the double-layer conveyor belt at different speeds, the demand of downstream equipment for continuous supply of syringes is solved, thereby improving production efficiency.

[0080] The above specific examples are used to illustrate the present invention, which is only used to help understand the present invention and is not intended to limit the present invention. For those skilled in the art, according to the concept of the present invention, some simple deductions, modifications or substitutions can be made.
