Specific embodiments

[0008] Embodiment 1 Combined with Figures 1 to 3 As shown, a medicine bottle conveying device for clamping a medicine bottle 91 and sealing the cover body 92 at the upper end of the medicine bottle 91 includes: A pair of clamping blocks 3 that can be driven to move to a combined or separated state. The clamping blocks 3 are provided with a clamping cavity 30 and an air cavity 31. When the pair of clamping blocks 3 are in a combined state, the clamping cavity 30 is used to clamp and circumferentially wrap the position of the medicine bottle 91 corresponding to the cover body 92, and the pair of air cavities 31 are combined to annularly cover the outer periphery and lower end of the cover body 92; Mounting frame 1; The mounting frame 1 is driven to move by a moving device (not shown); A pressing cap 2 disposed between the pair of clamping blocks 3. The upper end of the pressing cap 2 is provided with an extension rod 21, and the extension rod 21 is floatingly mounted on the mounting frame 1 in the longitudinal direction; The clamping block 3 is provided with a receiving cavity 32 adapted to the pressing cap 2; A transmission structure is provided between the pressing cap 2 and the clamping block 3. During the process of the clamping block 3 moving from the separated state to the combined state, the transmission structure is used to drive the pressing cap 2 to move downward by a preset first distance to tightly press against the upper end of the cover body 92. At this time, the inner wall of the receiving cavity 32 wraps around the radial outer side of the pressing cap 2, and the extension rod 21 extends upward from the receiving cavity 32 outside the clamping block 3.

[0009] Based on the above structure, in a medicine bottle conveying device in this embodiment, after the clamping blocks 3 are combined, the cover body 92 is clamped by the clamping cavity 30, and the air cavity 31 covers the outer periphery and lower end of the cover body 92 to block the intrusion of moisture when ventilating to block the medicine bottle 91 during the cleaning process. During the process of the clamping block 3 moving in the combined direction, the pressing cap 2 is driven by the transmission structure to move to tightly press against the upper end of the cover body 92, which can ensure that the cover body 92 is longitudinally pressed on the medicine bottle 91 and prevent the gas introduced into the air cavity 31 from invading the medicine bottle 91.

[0010] Combined with Figure 2 Combined Figure 3 As shown, in this embodiment, the clamping blocks 3 are slidably mounted on the mounting frame 1 in the horizontal direction, and the mounting frame 1 is provided with a driving assembly 4 for driving the clamping blocks 3 to move horizontally; The transmission structure includes a pair of guiding inclined surfaces 50 respectively located on the clamping block 3 and the pressing cap 2. During the process of the clamping block 3 moving towards the combined state, the guiding inclined surface 50 on the clamping block 3 abuts against the guiding inclined surface 50 on the pressing cap 2 to push the pressing cap 2 to move downward by a preset first distance. In this embodiment, the mounting frame 1 is provided with a laterally extending first guide rail 11, and the clamping blocks 3 are slidably mounted on the first guide rail 11. Combined with Figure 8As shown, in this embodiment, a transmission plate 33 is installed in the storage cavity 32, and the guiding inclined surface 50 is arranged on the transmission plate 33. Since the guiding inclined surface 50 on the clamping block 3 needs to be arranged in the storage cavity 32, and the grinding process of the storage cavity 32 is difficult, the transmission plate 33 is installed to ensure the smoothness of the guiding inclined surface 50 on the clamping block 3.

[0011] Combined with Figure 7 As shown, in this embodiment, the driving assembly 4 includes a driving frame 41 longitudinally slidably installed on the mounting frame 1 and a driver 42 for driving the driving frame 41 to move longitudinally relative to the mounting frame 1. A pair of clamping blocks 3 are symmetrically slidably connected to the driving frame 41 obliquely, so that during the longitudinal movement of the driving frame 41, a pair of clamping blocks 3 can be driven to move synchronously in an opening and closing manner. Based on the above device, a pair of clamping blocks 3 can be driven to move in a linked opening and closing manner, which has the advantage of simple control. When in the combined state, the driving force of the driver 42 can be evenly distributed to a pair of clamping blocks 3 to ensure the tight fit at the joint of the pair of clamping blocks 3, realizing the effective function of isolating water vapor, and also ensuring the consistency of the forces applied to the compression cap 2 by the transmission structures on both sides. Ensure the stability of the movement of the compression cap 2. In this embodiment, a longitudinally extending second guide rail 12 is provided on the mounting frame 1, and the driving frame 41 is slidably installed on the second guide rail 12. Combined with Figure 8 As shown, a sealing strip 34 is provided at the joint position where a pair of clamping blocks 3 are combined.

[0012] In this embodiment, a pair of obliquely extending slide rails 411 are provided on the driving frame 41, a transmission roller 38 is provided on the clamping block 3, and a spring 52 is provided between the clamping block 3 and the mounting frame 1. The spring 52 is used to apply an elastic force to the clamping block 3 so that the transmission roller 38 abuts against the slide rail 411. During the longitudinal movement of the driving frame 41, the slide rail 411 can push the air chamber 31 to move horizontally, realizing the synchronous movement of a pair of clamping blocks 3 in the separating or combining direction. Compared with the sliding connection of the slide rail and slider, it has the advantage of good load-bearing performance, so as to improve the service life. In this embodiment, the spring 52 is a tension spring, which is used to apply an elastic force to the clamping block 3 to move in the separating direction. A pair of slide rails 411 are in a shape of an inverted V, and the transmission roller 38 is a rolling bearing. In this embodiment, the driver 42 is a telescopic cylinder, and a limit convex portion 412 is provided at the end of the slide rail 411. When driving a pair of clamping blocks 3 to separate, the limit convex portion 412 is used to limit the movement of the air chamber 31 to limit the stroke of the driver 42. Setting the limit convex portion 412 can ensure that the clamping block 3 will not move over-position during the separating movement, and the movement stroke of the driver 42 is limited by the limit convex portion 412, which has the advantages of simple control and cost saving compared with in-position detection by a sensor. In this embodiment, the driving frames 41 are arranged in pairs on both sides of a pair of clamping blocks 3. Preferably, the telescopic cylinder is a pneumatic cylinder or a hydraulic cylinder.

[0013] The disadvantages of the existing capping medicine bottle conveying device also include that the centering positioning of the medicine bottle relative to the clamping blocks on both sides cannot be guaranteed before the clamping blocks on both sides move together, which will affect the sealing performance after the clamping blocks are combined.

[0014] In this regard, as shown in Figure 2 In this embodiment, a circular cavity 20 adapted to the upper end of the cover body 92 is provided at the bottom of the pressing cap 2; Before the pair of clamping blocks 3 are combined, move the mounting frame 1 from top to bottom to sleeved the circular cavity 20 on the upper end of the cover body 92; It also includes a sensor for detecting the displacement change amount of the pressing cap 2 relative to the mounting frame 1 during the process of the circular cavity 20 sleeving on the cover body 92.

[0015] Based on the above device, its principle is: by moving the mounting frame 1 so that the circular cavity 20 is sleeved on the cover body 92 to ensure the position accuracy of the medicine bottle 91 and the cover body 92. Since the pressing cap 2 is floatingly mounted on the mounting frame 1 through the extension rod 21, if the position of the medicine bottle 91 deviates, it will cause the outer edge of the cover body 92 to abut against the circular cavity 20 during the movement of the mounting frame 1 to sleeve the circular cavity 20 on the upper end of the cover body 92, resulting in the pressing cap 2 being lifted. Therefore, the sensor can judge whether the position of the medicine bottle 91 is accurately positioned by detecting the displacement change amount of the pressing cap 2 relative to the mounting frame 1 during this process. If the positioning error of the medicine bottle 91 is too large to be sleeved into the circular cavity 20, the system will alarm and terminate the subsequent operation to avoid losses.

[0016] As shown in Figure 2 Combined with Figure 5 In this embodiment, a mounting table 13 is provided on the mounting frame 1. The extension rod 21 passes through the mounting table 13 and is longitudinally slidably connected to the mounting table 13. A limit baffle 22 is provided on the extension rod 21. The limit baffle 22 is located at the upper end of the mounting table 13. A compression spring 53 is abutted between the mounting table 13 and the pressing cap 2. The compression spring 53 is sleeved on the extension rod 21. Before the pressing cap 2 abuts against the cover body 92, the limit baffle 22 abuts longitudinally against the mounting table 13 to limit the downward movement of the pressing cap 2 before the clamping blocks 3 are combined. Based on the above device, during the process of the mounting frame 1 moving to the longitudinal abutment of the pressing cap 2 and the cover body 92, the pressing cap 2 is lifted by a preset height h to make room for the downward displacement amount of the pressing cap 2 during the combination of the clamping blocks 3. If the height that the sensor detects the pressing cap 2 is lifted is greater than h, it means that the cover body 92 does not enter the circular cavity 20, and it can be judged that the positioning of the medicine bottle 91 is unqualified. In this embodiment, a linear bearing 131 is installed on the mounting table 13, and the extension rod 21 is slidably arranged in the linear bearing 131.

[0017] As shown in Figure 2As shown in the figure, in this embodiment, the sensor includes a Hall sensor 61 and a magnetic block 62 that are longitudinally opposed to each other. The Hall sensor 61 and the magnetic block 62 are respectively arranged on the limit baffle 22 and the mounting table 13. It has the advantages of simple installation and low cost compared with the optoelectronic distance measuring sensor. In this embodiment, a limit groove 132 is provided on the mounting table 13, and the extension rod 21 is inserted into the annular cavity of the limit groove 132. The upper end of the limit groove 132 is used to limit the downward movement of the limit baffle 22, and the magnetic block 62 is arranged at the bottom of the annular cavity of the limit groove 132.

[0018] Combined with Figure 3 , Figure 6 Combined with Figure 8 As shown in the figure, in this embodiment, the clamping block 3 includes: A housing 35, a transverse partition 351 is provided inside the housing 35, a transmission plate 33 is arranged on the upper side of the transverse partition 351, and an air inlet 350 is provided on the housing 35; An air distribution hood 36 installed inside the housing 35. The air distribution hood 36 abuts against the lower end of the transverse partition 351. A split air flow channel 360 is provided between the air distribution hood 36 and the housing 35. The air inlet 350 is communicated with the split air flow channel 360. A group of air distribution outlets 361 communicating the split air flow channel 360 and the air cavity 31 are provided on the air distribution hood 36; A chuck 37, the chuck 37 is installed on the radial inner side of the air distribution hood 36. The chuck 37 is integrally semi-circular. The chuck 37 includes a clamping portion 371 that abuts against the side wall of the medicine bottle 91 and / or the cap body 92 and a gas guiding portion 372 located at the lower end of the clamping portion 371. The inner wall of the clamping portion 371 encloses a clamping cavity 30. The air cavity 31 includes an air inlet cavity 311 located at the upper end of the clamping portion 371, an air outlet cavity 312 located inside the gas guiding portion 372, and a gas guiding groove 313 provided on the inner wall of the clamping portion 371. The gas guiding groove 313 communicates the air inlet cavity 311 and the air outlet cavity 312. In this embodiment, the material of the chuck 37 is elastic plastic.

[0019] Combined with Figure 4 As shown in the figure, in this embodiment, a steam blocking groove 373 is provided on the inner wall of the gas guiding portion 372. The steam blocking groove 373 is semi-circular, including a tapered surface 3731 that is wider at the top and narrower at the bottom and a horizontal semi-circular blocking surface 3732 at the upper end of the tapered surface 3731. Among them, the steam blocking groove 373 is used to block the rising of water vapor through the air outlet cavity 312.

[0020] Combined with Figure 9 As shown in the figure, in this embodiment, the bottom of the compression cap 2 is provided with a first annular flange 23 and a second annular flange 24. The first annular flange 23 and the second annular flange 24 respectively correspond to the inner diameter and outer diameter positions of the mouth of the medicine bottle 91. When the compression cap 2 is pressed on the cap body 92, the first annular flange 23 and the second annular flange 24 are recessed into the end face of the cap body 92, which can make the inner and outer diameter positions of the cap body 92 and the mouth of the medicine bottle 91 fit tightly to improve the sealing performance.

[0021] In other embodiments, it is necessary to press-fit an envelope 93 onto the cover 92. The cavity of the envelope 93 is adapted to the shape of the upper end of the cover 92. After the envelope 93 is wrapped around the cover 92, the first annular flange 23 and the second annular flange 24 can press the envelope 93 onto the cover 92.

[0022] Embodiment 2 Based on Embodiment 1, in this embodiment, in combination with Figure 9 as shown, a suction cup 25 is provided on the pressing cap 2 corresponding to the inner side of the first annular flange 23. The suction cup air passage 251 communicating with the suction cup 25 longitudinally penetrates the pressing cap 2 and the extension rod 21. The suction cup 25 is used to suck the envelope 93. By integrally moving the mounting bracket 1, the envelope 93 is sleeved on the cover 92, and then the driving clamp 3 is moved to be combined to tightly press the envelope 93 onto the cover 92. In the natural state, the suction cup 25 protrudes from the lower end of the first annular flange 23, and a suction cup groove 230 is provided corresponding to the inner side of the first annular flange 23 for receiving the squeezed suction cup 25 when the first annular flange 23 presses the envelope 93. Therefore, a medicine bottle conveying device can also transfer the envelope 93 and press the envelope 93 onto the cover 92, having the advantage of high integration. Its usage method includes the following steps: S1: The moving device (not shown) integrally moves the mounting bracket 1 to pick up the envelope 93, so that the envelope 93 enters the circular cavity 20 and is sucked by the suction cup 25. S2: In combination with Figure 10 as shown in the left figure to the middle figure of, the moving device integrally moves the mounting bracket 1 above the medicine bottle 91, and moves the mounting bracket 1 downward from top to bottom until the cover 92 enters the cavity of the envelope 93. During this process, the pressing cap 2 is lifted, and due to the elastic force of the compression spring 53, it can ensure the longitudinal fitting of the envelope 93 and the cover 92, avoiding the longitudinal non-tight fitting of the envelope 93 and the cover 92 caused by the friction between the side surfaces of the envelope 93 and the cover 92. S3: The sensor detects whether the pressing cap 2 rises a preset height h relative to the mounting bracket 1 in step S2. If the rising height of the pressing cap 2 is greater than the preset height h, it indicates that the positioning of the medicine bottle 91 is deviated, and the machine stops and alarms; if the rising height of the pressing cap 2 is equal to h, step S4 is executed; S4: In combination with Figure 10 as shown in the right figure of, the driving assembly 4 drives a pair of clamps 3 to move to the combined state. At this time, the medicine bottle 91 is clamped, and the envelope 93 is tightly pressed onto the cover 92. S5: Move the mounting bracket 1 to the cleaning station to wash the body of the medicine bottle 91. During the washing process, the valve between the air inlet 350 and the air source is opened, and the air cavity 31 wraps the gap between the medicine bottle 91 and the cover 92 to prevent moisture from invading. S6: After the cleaning is completed, the mounting frame 1 is moved to the discharging station, the driving assembly 4 drives a pair of clamping blocks 3 to move to a separated state, and the medicine bottle 91 is placed at the discharging station.

[0023] Repeat steps S1 to S6 to achieve automatic cycle operation.

[0024] In this embodiment, combined with Figures 6 to 8 As shown, the lower end of the corresponding cover 92 of the medicine bottle 91 is provided with an annular retaining edge 911 for limiting the position. After the cover 92 is longitudinally pressed, it contacts the annular retaining edge 911. The inner wall of the clamping surface of the corresponding clamping portion 371 includes, from top to bottom, a first fitting surface 3711 that fits with the side wall of the cover 92, a second fitting surface 3712 that fits with the bottom of the annular retaining edge 911, and a third fitting surface 3713 that fits with the side wall of the bottleneck of the medicine bottle 91. When the cover 92 enters the sleeve cavity of the envelope 93 and the cover 92 and the envelope 93 fit tightly longitudinally, at this time, the lower edge of the envelope 93 goes downward over the annular retaining edge 911. Therefore, after step S4 is executed, combined with Figure 10 As shown in the right figure in FIG. , the sleeve 93 wraps around the lower end surface of the annular retaining edge 911.

[0025] In one embodiment, a heating module is provided in the circular cavity 20 , and the envelope 93 is made of a heat shrink material. After step S4 is completed, the heating module works so that the envelope 93 is tightly wrapped around the cover 92 and the outer side of the annular retaining edge 911 .
