Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical packaging machinery technology, and in particular to an integrated cap feeding and pressing device. Background Technology

[0002] Pre-filling needles in filling machines require capping to ensure product sealing and prevent leakage, contamination, or deterioration. However, existing capping processes for pre-filling needles typically involve initial loading and positioning of the caps in a single unit, followed by transfer via a conveyor line to another unit for pressurization or tightening. While this design ensures a certain success rate and reliability in the pressing process, it has significant drawbacks: the linear conveyor structure itself occupies a large amount of floor space, and the multi-unit design requires more operating areas, resulting in a large overall equipment size and a less compact structure, putting pressure on cleanroom space utilization. Furthermore, multiple units mean the need for multiple actuators, sensors, and control systems, increasing equipment complexity and manufacturing costs, as well as raising maintenance difficulty and energy consumption.

[0042] Figure 1 This is a schematic structural diagram of an integrated cap-feeding and cap-pressing device provided in one embodiment of this utility model. Figure 1 As shown, and refer to Figures 2 to 14 This utility model provides a cap feeding and pressing integrated device, including a turntable assembly 100, a first feeding assembly 200, and a second feeding assembly 300. The turntable assembly 100 is rotatably configured and has multiple feeding stations 110. The first feeding assembly 200 is disposed on one side of the turntable assembly 100 and is used to convey the pre-filled needle tube 620 to the feeding station 110. The second feeding assembly 300 is disposed at intervals from the first feeding assembly 200 along the circumference of the turntable assembly 100. The second feeding assembly 300 has a feeding part 310 and a transfer part 320. The feeding part 310 is used to convey the protective cap 610. The transfer part 320 is disposed at one end of the feeding part 310 near the feeding station 110 and is used to transfer the protective cap 610 and press it onto the pre-filled needle tube 620.

[0043] In this embodiment, a first feeding assembly 200 and a second feeding assembly 300 are sequentially arranged around the turntable assembly 100, respectively for conveying the pre-filled syringe 620 and the protective cap 610. After the pre-filled syringe 620 is conveyed to the feeding station 110, the turntable assembly 100 rotates to move the feeding station 110 with the pre-filled syringe 620 to the second feeding assembly 300. The transfer part 320 of the second feeding assembly 300 transfers the protective cap 610 and presses it onto the pre-filled syringe 620, realizing the feeding, positioning and pressurization of the protective cap 610 on a single device. This saves operating space, reduces equipment complexity and manufacturing costs, and reduces the difficulty of later maintenance and energy consumption.

[0044] like Figure 2 , Figure 13 , Figure 14 As shown, in one embodiment of this utility model, the turntable assembly 100 includes a turntable body 120, grippers 130, and a drive unit 140. A loading station 110 is disposed on the turntable body 120, and each loading station 110 is provided with multiple grippers 130. The drive unit 140 is disposed at the bottom of the turntable body 120 to drive the turntable body 120 to rotate. Further, the first loading assembly 200 includes a conveyor belt 210 and a tray 220 disposed on the conveyor belt 210. The tray 220 is used to carry pre-filled syringes 620. In application, the conveyor belt 210 transports the tray 220 and the pre-filled syringes 620 thereon to a position close to the turntable body 120, and then a hoisting robot picks up the pre-filled syringes 620 and feeds them into the grippers 130 on the loading station 110. Finally, by starting the drive unit 140 to rotate, the drive unit 140 drives the turntable body 120 to rotate, and the pre-filled syringe 620 is moved to the next station.

[0045] like Figure 5 , Figure 6 As shown, in one embodiment of this utility model, the feeding part 310 includes a track 311, a vibrating element, and a cap receiving arm 312. The output end of the vibrating element is connected to the track 311 to drive the track 311 to vibrate. The cap receiving arm 312 is disposed at one end of the track 311 near the transfer part 320 and is used to stop the cap 610. Specifically, along the length direction of the track 311, the width of the track 311 decreases, and the narrow end of the track 311 is the end near the turntable body 120, so that the cap 610 can vibrate and move in the track 311 to the position of the cap receiving arm 312.

[0046] like Figures 6 to 9As shown, in one embodiment of this utility model, the transfer part 320 includes a clamping member 321 and a flipping shaft 322. The clamping member 321 is movably disposed above the cap receiving arm 312. The clamping member 321 is provided with a telescopic sleeve 3211. When the sleeve 321 extends out of the clamping member 321, it is inserted into the cap 610. There are multiple sleeves 3211, and they are arranged one-to-one with the track 311. The flipping shaft 322 is rotatably disposed between the loading part 310 and the loading station 110. The side wall of the flipping shaft 322 is provided with a cap feeding arm 323 for clamping the cap 610. When the flipping shaft 322 rotates to the first position, the cap feeding arm 323 is located below the clamping member 321. When the flipping shaft 322 rotates to the second position, the cap feeding arm 323 is located above the loading station 110.

[0047] Through the coordinated design of the clamping component 321 and the flipping shaft 322, high-precision transfer and capping operations of the cap 610 are achieved. The clamping component 321 is movably positioned above the cap receiving arm 312 to ensure accurate gripping of the cap 610. Specifically, before the flipping shaft 322 rotates to the first position, the clamping component 321 moves downward, while the sleeve 3211 extends downward and inserts into the cap 610, forming an interference fit with it. Then, the clamping component 321 moves upward, bringing the cap 610 out of the cap receiving arm 312 position. The flipping shaft 322 drives the cap feeding arm 323 to switch between two key positions through rotational motion. The first position is used to receive the cap 610 transferred by the clamping component 321, and the second position is precisely positioned above the loading station 110 to complete the capping operation. This design not only simplifies the transfer path of the cap 610 and reduces space occupation, but also improves the alignment accuracy and operational stability of the cap through a rotation positioning mechanism, reducing reliance on complex multi-axis mechanical structures, thereby improving the overall reliability and production efficiency of the equipment.

[0048] Furthermore, the transfer unit 320 also includes a first lifting assembly 324 and a second lifting assembly 326. The output end of the first lifting assembly 324 is connected to a connecting block, and the flipping shaft 322 is rotatably connected to the connecting block. By setting the first lifting assembly 324, a vertical lifting freedom is introduced into the cap-pressing process. When the flipping shaft 322 rotates to the second position, the first lifting assembly 324 drives the flipping shaft 322 to move downwards, which improves the accuracy and reliability of the cap transfer and capping process. A clamping member 321 is disposed on the output end of the second lifting assembly 326, so that the second lifting assembly 326 drives the clamping member 321 to move up and down.

[0049] like Figure 3 , Figures 10 to 12As shown, in one embodiment of this utility model, the cap-feeding arm 323 includes a first fixing block 3231, a second fixing block 3232, a clamping block 3233, and a spring 3235. The first fixing block 3231 is fixedly connected to the flipping shaft 322. The first fixing block 3231 and the second fixing block 3232 are spaced apart and fixedly connected by a plurality of fixing rods 3234. The clamping block 3233 is disposed between the first fixing block 3231 and the second fixing block 3232. The fixing rods 3234 pass through the clamping block 3233, and the clamping block 3233 can reciprocate along the axial direction of the fixing rods 3234. The spring 3235 is disposed between the clamping block 3233 and the first fixing block 3231 to drive the clamping block 3233 to fit against the second fixing block 3232. The end of the clamping block 3233 is provided with a first protrusion 3236. The hat feeding and pressing integrated device also includes a drive block 325, which is located at the end of the clamping block 3233 where the first protrusion 3236 is located, and is located on one side of the first protrusion 3236. The drive block 325 is provided with a second protrusion 3251, which is configured to squeeze the first protrusion 3236 when the hat feeding arm 323 moves downward, so as to drive the clamping block 3233 to move towards the first fixing block 3231.

[0050] In this embodiment, when the cap-feeding arm 323 rotates to the first position, the second lifting assembly 326 drives the clamping member 321 to move downward, sending the cap 610 between the second fixing block 3232 and the clamping block 3233. At the same time, the spring 3235 is compressed, and then the sleeve rod 3211 retracts into the clamping member 321. Under the stop of the part around the sleeve rod 3211 on the clamping member 321, the sleeve rod 3211 is retracted into the clamping member 321, while the cap 610 is left between the second fixing block 3232 and the clamping block 3233. At the same time, under the action of the elastic force of the spring 3235, the cap 610 is tightly clamped between the second fixing block 3232 and the clamping block 3233. At this time, the opening of the cap 610 faces upward.

[0051] Then, the cap-feeding arm 323 rotates 150° to 200° to the second position, at which point the cap 610 is positioned with its opening facing downwards and directly above the pre-filled syringe 620 in the loading station 110. The first lifting assembly 324 drives the cap-feeding arm 323 downwards via the flipping shaft 322. During the movement: the first protrusion 3236 first contacts the second protrusion 3251 on the driving block 325. As the movement continues, the first protrusion 3236 and the second protrusion 3251 press against each other, causing the first protrusion 3236 to move the clamping block 3233 away from the second fixing block 3232, thus releasing the cap 610 and placing it on the pre-filled syringe 620. At this time, the spring 3235 is compressed again. After the first protrusion 3236 passes the second protrusion 3251, the spring 3235 returns to its original shape, causing the clamping block 3233 to fit tightly against the second fixing block 3232. The cap delivery arm 323 continues to move downwards, pressing the cap 610 onto the pre-filled syringe 620, completing the cap pressing action.

[0052] This embodiment of the invention seamlessly connects the multiple steps of transferring, aligning, releasing, and pressing the cap 610 by linking the rotation / lifting of the cap-feeding arm 323 and the clamping and placing of the clamping block 3233, significantly improving production efficiency. During application, the elastic force of the spring 3235 drives the clamping block 3233 to engage with the second fixing block 3232 to hold the cap 610. The clamping force is stable and controllable, effectively preventing the cap 610 from accidentally falling off during transport. Furthermore, through the ingenious interaction between the second protrusion 3251 on the driving block 325 and the first protrusion 3236 on the clamping block 3233, a precise mechanical trigger release is achieved: the clamping block 3233 is squeezed and moved to release the cap 610 only when the cap-feeding arm 323 is pressed down to a specific position, ensuring that the cap 610 is accurately placed onto the pre-filled syringe 620 at the correct time and position.

[0053] Preferably, the first protrusion 3236 is a bearing, the axis of which is perpendicular to the moving direction of the cap feeding arm 323, and the peripheral surface of the bearing is in contact with the second protrusion 3251.

[0054] Furthermore, the second fixing block 3232 has a first protrusion 32321 on the upper part of the side near the clamping block 3233, and the clamping block 3233 has a second protrusion 32331 on the lower part of the side near the second fixing block 3232; when the first protrusion 32321 is in contact with the clamping block 3233, the second protrusion 32331 is in contact with the second fixing block 3232. A through hole 32322 is provided at the connection between the second fixing block 3232 and the first protrusion 32321. A first semi-blind hole 32323, coaxial with and communicating with the through hole 32322, is provided at the lower part of the second fixing block 32321. A second semi-blind hole 32332, coaxial with the through hole 32322, is provided on the side of the second protrusion 32331 facing the second fixing block 3232. When the second protrusion 32331 and the second fixing block 3232 are in contact, the first semi-blind hole 32323 and the second semi-blind hole 32332 surround each other and communicate with the through hole 32322, forming a larger blind hole. Furthermore, the diameters of the first semi-blind hole 32323 and the second semi-blind hole 32332 decrease progressively, and the larger diameter end communicates with the through hole 32322.

[0055] It should be noted that a semi-blind hole is a combination of the terms "semi-hole" and "blind hole," meaning a structure formed by dividing a blind hole into two parts along its axis or in a direction parallel to it.

[0056] In this embodiment, when the second lifting assembly 326 moves the clamping member 321 downward, the protective cap 610 first enters the through hole 32322; as the clamping member 321 continues to move downward, the protective cap 610 enters between the first semi-blind hole 32323 and the second semi-blind hole 32332; since the diameters of the first semi-blind hole 32323 and the second semi-blind hole 32332 decrease, the sleeve rod 3211 moves downward, spreading the second fixing block 3232 and the second protrusion 32331 apart, compressing the spring 3235; then the sleeve rod 3211 retracts upward into the clamping member 321, and the portion around the sleeve rod 3211 on the clamping member 321 stops the protective cap 610, keeping it inside the blind hole, while the spring 3235 returns to its original shape, causing the second protrusion 32331 to move closer to the second fixing block 3232, tightly clamping the protective cap 610. Figure 11As shown, when the cap-feeding arm 323 rotates 180° to the second position, the cap 610 is positioned with its opening facing downwards and directly above the pre-filled syringe 620 in the loading station 110. The first lifting assembly 324 drives the cap-feeding arm 323 downwards via the flipping shaft 322. During the movement: the first protrusion 3236 first contacts the second protrusion 3251 on the driving block 325. As the movement continues, the first protrusion 3236 and the second protrusion 3251 press against each other, causing the first protrusion 3236 to drive the clamping block 3233 to move away from the second fixing block 3232. The second fixing block 3232 separates from the second protrusion 32331, releasing the cap 610 and placing it on the pre-filled syringe 620. At this time, the spring 3235 is compressed again. After the first protrusion 3236 passes the second protrusion 3251, the spring 3235 returns to its original shape, causing the clamping block 3233 to fit tightly against the second fixing block 3232. The cap-feeding arm 323 continues to move downwards, and the bottom of the blind hole abuts against the cap 610. Under the action of the first lifting component 324, the cap 610 is pressed onto the pre-filled syringe 620, completing the cap-pressing action.

[0057] This embodiment of the invention enhances the alignment and stability of the clamping by cooperating with the first protrusion 32321 on the second fixing block 3232 and the second protrusion 32331 on the clamping block 3233. Furthermore, the designed through hole 32322, the first semi-blind hole 32323, and the second semi-blind hole 32332 together form a cavity for guiding and accommodating the cap 610. This not only helps in the initial positioning of the cap 610 before clamping but also better constrains the cap 610 during the pressing process, preventing it from tilting and ensuring the pressing quality. The decreasing diameter design of the two semi-blind holes helps the sleeve rod to spread the second fixing block 3232 and the second protrusion 32331, providing better holding force for clamping the cap 610. Therefore, the integrated cap feeding and pressing device of this embodiment not only improves the efficiency and automation of cap 610 installation but, more importantly, significantly improves the positioning accuracy, operational stability, and final pressing quality of the cap 610 during the conveying, releasing, and pressing processes through its reliable mechanical structure and ingenious logical coordination.

[0058] Specifically, the upper end of the clamping member 321 is provided with a drive motor, and the sleeve rod 3211 passes through the clamping member 321 and is connected to the output end of the drive motor, so that the drive motor drives the sleeve rod 3211 to move up and down, so that the sleeve rod 3211 extends out of the clamping member 321 or retracts into the clamping member 321. Alternatively, the upper end of the clamping member 321 is provided with a cylinder, and the sleeve rod 3211 is connected to the piston rod of the cylinder.

[0059] In one embodiment of this utility model, the turntable assembly 100 further includes a positioning mechanism 150, which has a positioning pin 151 that can extend and retract vertically. The turntable body 120 is provided with multiple positioning holes, each corresponding to a loading station 110. When the turntable rotates to a preset position, the positioning pin 151 extends upward and inserts into the corresponding positioning hole, achieving precise positioning. At this time, the loading station 110 can be locked by a knob, thereby adapting to the installation requirements of pre-filled syringes of different specifications and models.

[0060] In addition, such as Figure 4 As shown, the cap feeding and cap pressing integrated device also includes a feeding robot 400 and a feeding slide rail 500. Along the rotation direction of the turntable assembly 100, the feeding robot 400 is positioned downstream of the second feeding assembly 300, used to clamp and transfer the pre-filled needle tube 620 after cap pressing onto the feeding slide rail 500. After cap pressing is completed, the turntable body 120 continues to rotate, rotating the pre-filled needle tube 620 with the cap pressed to the position of the feeding robot 400, which then clamps the pre-filled needle tube 620 and transfers it onto the feeding slide rail 500, completing the discharge action.
