[0002] After being capped and packaged, medicine bottles need to be cleaned at the washing station. The traditional process involves conveying the bottles to the capping station, sealing them, and then using a conveyor to hold them before moving them to the washing station. Therefore, this process requires three work cycles: capping, holding, and conveying, which is inefficient. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, the present invention provides a capped packaging type medicine bottle transport device, which can improve work efficiency compared with traditional processes.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0006] The mounting bracket is moved by a mobile device;

[0007] A pair of clamping blocks are provided on the mounting bracket. The pair of clamping blocks can be driven to be in an engaged or disengaged state. The clamping blocks are provided with clamping cavities.

[0008] A pressure cap is located between a pair of clamping blocks. The upper end of the pressure cap is provided with an extension rod, which is floated longitudinally on the mounting frame. The bottom of the pressure cap is provided with a circular cavity that adapts to the upper end of the cover. A suction cup is provided inside the circular cavity, and the suction cup is used to pick up the cover.

[0009] The transmission structure located between the pressure cap and the clamping block drives the pressure cap to move downward a preset first distance during the process of the clamping block moving from a separated state to a joined state, so as to tightly cover the cap body and clamp the medicine bottle in the clamping cavity.

[0010] As can be seen from the above technical solution, the present invention has the following beneficial effects:

[0011] This application discloses a capped packaging type medicine bottle transport device, the method of use of which is as follows: the moving device moves the entire mounting frame to pick up the seal, allowing the seal to enter the circular cavity, and the seal is held in place by a suction cup; the moving device moves the entire mounting frame above the medicine bottle, and moves the mounting frame downwards until the cap enters the cavity of the seal, during which the pressure cap is raised; a pair of clamping blocks are driven to move to the engaging state, at which point the medicine bottle is clamped and the seal is tightly pressed onto the cap; finally, the mounting frame is moved to the cleaning station. Therefore, this capped packaging type medicine bottle transport device unifies the working rhythm of capping packaging and clamping, improving work efficiency compared to traditional processes.

[0030] Example 1

[0031] Combination Figures 1 to 3 The illustrated medicine bottle conveying device, used to clamp a medicine bottle 91 and seal the cap 92 at the upper end of the medicine bottle 91, includes:

[0032] A pair of clamping blocks 3 that can be driven to be in a closed or open state. The clamping blocks 3 are provided with clamping cavities 30 and air cavities 31. When the pair of clamping blocks 3 are in a closed state, the clamping cavity 30 is used to clamp and circumferentially wrap the position of the medicine bottle 91 corresponding to the cap 92, and the pair of air cavities 31 are joined to annularly cover the outer periphery and lower end of the cap 92.

[0033] Mounting bracket 1; Mounting bracket 1 is moved by a moving device (not shown);

[0034] A pressure cap 2 is provided between a pair of clamping blocks 3. An extension rod 21 is provided at the upper end of the pressure cap 2. The extension rod 21 is floated on the mounting frame 1 along the longitudinal direction.

[0035] The clamping block 3 is provided with a storage cavity 32 that is compatible with the pressure cap 2;

[0036] A transmission structure is provided between the pressure cap 2 and the clamping block 3. During the process of the clamping block 3 moving from the separated state to the joined state, the transmission structure is used to drive the pressure 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 storage cavity 32 covers the radial outer side of the pressure cap 2, and the extension rod 21 extends upward from the storage cavity 32 out of the outer side of the clamping block 3.

[0037] Based on the above structure, in this embodiment of the medicine bottle conveying device, after the clamping blocks 3 are engaged, they clamp the cap 92 through the clamping cavity 30, and the air cavity 31 covers the outer periphery and lower end of the cap 92 to allow air to pass through during the cleaning process and prevent moisture from entering the medicine bottle 91. During the movement of the clamping blocks 3 in the engagement direction, the pressure cap 2 is driven by the transmission structure to move to a position where it is tightly pressed against the upper end of the cap 92, ensuring that the cap 92 is longitudinally pressed against the medicine bottle 91 and preventing gas introduced into the air cavity 31 from entering the medicine bottle 91.

[0038] Combination Figure 2 combine Figure 3 As shown, in this embodiment, the clamping block 3 is slidably mounted on the mounting frame 1 in a horizontal direction. The mounting frame 1 is provided with a driving assembly 4 for driving the clamping block 3 to move horizontally. The transmission structure includes a pair of guide ramps 50 located on the clamping block 3 and the pressure cap 2 respectively. During the movement of the clamping block 3 toward the mating state, the guide ramps 50 on the clamping block 3 abut against the guide ramps 50 on the pressure cap 2 to push the pressure cap 2 downward by a preset first distance. In this embodiment, the mounting frame 1 is provided with a first guide rail 11 extending laterally, and the clamping block 3 is slidably mounted on the first guide rail 11. Figure 8 As shown, in this embodiment, a transmission plate 33 is installed inside the receiving cavity 32, and a guide slope 50 is disposed on the transmission plate 33. Since the guide slope 50 on the clamping block 3 needs to be disposed inside the receiving cavity 32, and the receiving cavity 32 is difficult to grind, the transmission plate 33 is installed to ensure the smoothness of the guide slope 50 on the clamping block 3.

[0039] Combination Figure 7 As shown, in this embodiment, the drive assembly 4 includes a drive frame 41 longitudinally slidably mounted on the mounting frame 1 and a driver 42 that drives the drive frame 41 to move longitudinally relative to the mounting frame 1. A pair of clamping blocks 3 are slidably connected to the drive frame 41 along an oblique direction, so that the drive frame 41 can drive the pair of clamping blocks 3 to open and close synchronously during longitudinal movement. Based on the above device, the pair of clamping blocks 3 can be driven to open and close in linkage, which has the advantage of simple control. In the closed state, the driving force of the driver 42 can be evenly distributed to the pair of clamping blocks 3 to ensure a tight fit at the joint of the pair of clamping blocks 3, effectively isolating moisture, and also ensuring the consistency of the force applied to the pressure cap 2 by the transmission structures on both sides. This ensures the stability of the movement of the pressure cap 2. In this embodiment, the mounting frame 1 is provided with a longitudinally extending second guide rail 12, and the drive frame 41 is slidably mounted on the second guide rail 12. Figure 8 As shown, a sealing strip 34 is provided at the joint where the two clamping blocks 3 meet.

[0040] In this embodiment, the drive frame 41 is provided with a pair of obliquely extending slide rails 411, the clamping block 3 is provided with a transmission roller 38, and a spring 52 is provided between the clamping block 3 and the mounting frame 1. The spring 52 is used to apply 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 drive frame 41, the slide rail 411 can push the air chamber 31 to move horizontally, so that the pair of clamping blocks 3 can move synchronously in the direction of separation or reunification. Compared with the sliding connection of the slide rail and slider, it has the advantage of good load-bearing performance, thereby improving service life. In this embodiment, the spring 52 is a tension spring, which is used to apply elastic force to the clamping block 3 in the direction of separation. The pair of slide rails 411 are V-shaped, and the transmission roller 38 is a rolling bearing. In this embodiment, the driver 42 is a telescopic cylinder, and the end of the slide rail 411 is provided with a limiting protrusion 412. When driving the pair of clamping blocks 3 to separate, the limiting protrusion 412 is used to limit the movement of the air chamber 31 to limit the stroke of the driver 42. The limiting protrusion 412 ensures that the clamping blocks 3 will not move excessively during separation. By limiting the travel of the driver 42 through the limiting protrusion 412, it offers advantages over sensor-based detection, offering simpler control and lower costs. In this embodiment, the drive frame 41 is 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.

[0041] The existing capping medicine bottle conveying device also has the disadvantage that it cannot guarantee the centering of the medicine bottle relative to the two clamps before the clamps on both sides move together, which will affect the sealing performance after the clamps are engaged.

[0042] In this regard, combined with Figure 2 As shown, in this embodiment, the bottom of the pressure cap 2 is provided with a circular cavity 20 that is adapted to the upper end of the cover 92;

[0043] Before the pair of clamps 3 are engaged, the mounting bracket 1 is moved from top to bottom to fit the cavity 20 onto the upper end of the cover 92;

[0044] It also includes a sensor for detecting the displacement change of the pressure cap 2 relative to the mounting bracket 1 during the process of the circular cavity 20 being fitted onto the cover 92.

[0045] Based on the above device, the principle is as follows: by moving the mounting frame 1 so that the cavity 20 fits onto the cap 92, the positional accuracy of the medicine bottle 91 and the cap 92 is ensured. Since the pressure cap 2 is floatingly mounted on the mounting frame 1 via the extension rod 21, if the position of the medicine bottle 91 deviates, it will cause the cap 92 to abut against the outer edge of the cavity 20 during the movement of the mounting frame 1 to fit the cavity 20 onto the upper end of the cap 92, causing the pressure cap 2 to be lifted. Therefore, the sensor can determine whether the position of the medicine bottle 91 is accurately positioned by detecting the displacement change of the pressure cap 2 relative to the mounting frame 1 during this process. If the positioning error of the medicine bottle 91 is too large and it cannot fit into the cavity 20, the system will alarm and terminate the subsequent operation to avoid losses.

[0046] Combination Figure 2 combine Figure 5 As shown, in this embodiment, the mounting frame 1 is provided with a mounting platform 13, and an extension rod 21 passes through the mounting platform 13 and is longitudinally slidably connected to the mounting platform 13. A limiting baffle 22 is provided on the extension rod 21, and the limiting baffle 22 is located at the upper end of the mounting platform 13. A compression spring 53 abuts between the mounting platform 13 and the pressure cap 2, and the compression spring 53 is sleeved on the extension rod 21. Before the pressure cap 2 abuts against the cover 92, the limiting baffle 22 abuts against the mounting platform 13 longitudinally to restrict the downward movement of the pressure cap 2, before the clamping block 3 closes. Based on the above device, during the process of the mounting frame 1 moving to the point where the pressure cap 2 abuts against the cover 92 longitudinally, the pressure cap 2 is raised by a preset height h to allow for the downward displacement of the pressure cap 2 during the closing of the clamping block 3. If the sensor detects that the height of the pressure cap 2 raised is greater than h, it indicates that the cover 92 has not entered the circular cavity 20, and it can be determined that the positioning of the medicine bottle 91 is unqualified. In this embodiment, a linear bearing 131 is installed on the mounting platform 13, and the extension rod 21 is slidably disposed inside the linear bearing 131.

[0047] Combination Figure 2 As shown, in this embodiment, the sensor includes a Hall sensor 61 and a magnetic block 62 facing each other longitudinally. The Hall sensor 61 and the magnetic block 62 are respectively disposed on the limiting baffle 22 and the mounting platform 13. Compared with photoelectric ranging sensors, it has the advantages of simple installation and low cost. In this embodiment, the mounting platform 13 is provided with a limiting groove 132, and the extension rod 21 passes through the annular cavity of the limiting groove 132. The upper end of the limiting groove 132 is used to restrict the downward movement of the limiting baffle 22, and the magnetic block 62 is disposed at the bottom of the annular cavity of the limiting groove 132.

[0048] Combination Figure 3 , Figure 6 combine Figure 8 As shown, in this embodiment, the clamping block 3 includes:

[0049] The housing 35 has a transverse partition 351 inside, a transmission plate 33 is disposed on the upper side of the transverse partition 351, and an air inlet 350 is provided on the housing 35.

[0050] The air distribution hood 36 is installed inside the housing 35. The air distribution hood 36 abuts against the lower end of the transverse partition 351. An air distribution channel 360 is provided between the air distribution hood 36 and the housing 35. The air inlet 350 is connected to the air distribution channel 360. The air distribution hood 36 is provided with a set of air distribution outlets 361 that connect the air distribution channel 360 and the air chamber 31.

[0051] A clamp 37 is installed radially inside the gas distribution hood 36. The clamp 37 is semi-circular in shape and includes a clamping portion 371 that abuts against the side wall of the medicine bottle 91 and / or the cap 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 forms a clamping cavity 30. The gas cavity 31 includes an air inlet cavity 311 located at the upper end of the clamping portion 371 and an air outlet cavity 312 located inside the gas guiding portion 372, as well as a gas guiding groove 313 provided on the inner wall of the clamping portion 371. The gas guiding groove 313 connects the air inlet cavity 311 and the air outlet cavity 312. In this embodiment, the clamp 37 is made of elastic plastic.

[0052] Combination Figure 4 As shown, in this embodiment, the inner wall of the air guide 372 is provided with a steam-blocking groove 373. The steam-blocking groove 373 is semi-annular and includes a conical surface 3731 that is wider at the top and narrower at the bottom, and a horizontal semi-annular blocking surface 3732 at the upper end of the conical surface 3731. The steam-blocking groove 373 is used to prevent water vapor from rising and passing through the air outlet 312.

[0053] Combination Figure 9 As shown, in this embodiment, the bottom of the cap 2 is provided with a first annular flange 23 and a second annular flange 24, which correspond to the inner and outer diameters of the mouth of the medicine bottle 91, respectively. When the cap 2 is pressed onto the cover 92, the first annular flange 23 and the second annular flange 24 are embedded in the end face of the cover 92, which allows the cover 92 to fit tightly against the inner and outer diameters of the mouth of the medicine bottle 91, thereby improving the sealing performance.

[0054] In other embodiments, a sleeve 93 needs to be pressed onto the cover 92. The cavity of the sleeve 93 is adapted to the shape of the upper end of the cover 92. After the sleeve 93 covers the cover 92, the first annular flange 23 and the second annular flange 24 can press the sleeve 93 onto the cover 92.

[0055] Example 2

[0056] Based on Example 1, in this example, combined with Figure 9As shown, a suction cup 25 is provided on the inner side of the first annular flange 23 on the pressure cap 2. The suction cup air passage 251 connecting the suction cup 25 longitudinally passes through the pressure cap 2 and the extension rod 21. The suction cup 25 is used to pick up the cover 93. By moving the overall mounting bracket 1, the cover 93 is placed on the cap 92. Then, by moving the drive clamp 3 to engage, the cover 93 is tightly pressed onto the cap 92. In its natural state, the suction cup 25 protrudes from the lower end of the first annular flange 23. A suction cup groove 230 is provided on the inner side of the first annular flange 23 to receive the squeezed suction cup 25 when the first annular flange 23 presses the cover 93. Therefore, a medicine bottle conveying device can also transfer the cover 93 and press the cover 93 onto the cap 92, which has the advantage of high integration. Its usage method includes the following steps:

[0057] S1: The mobile device (not shown) moves the entire mounting frame 1 to pick up the cover 93, so that the cover 93 enters the circular cavity 20 and is held in place by the suction cup 25;

[0058] S2: Combination Figure 10 As shown in the left to middle figure, the moving device moves the mounting bracket 1 to the top of the medicine bottle 91 and moves the mounting bracket 1 from top to bottom until the cap 92 enters the cavity of the sleeve 93. During this process, the pressure cap 2 is raised. Due to the elastic force of the pressure spring 53, the sleeve 93 and the cap 92 can be longitudinally fitted, avoiding the friction between the sides of the sleeve 93 and the cap 92, which would cause the sleeve 93 and the cap 92 to not fit tightly in the longitudinal direction.

[0059] S3: The sensor detects whether the pressure cap 2 has risen a preset height h relative to the mounting bracket 1 in step S2. If the pressure cap 2 rises a height greater than the preset height h, it indicates that the positioning of the medicine bottle 91 has deviated, and the machine stops and alarms. If the pressure cap 2 rises a height equal to h, then step S4 is executed.

[0060] S4: Combination Figure 10 As shown in the right figure, the drive component 4 drives a pair of clamping blocks 3 to move to the mating state. At this time, the medicine bottle 91 is clamped and the cover 93 is tightly pressed onto the cap 92.

[0061] S5: Move the mounting bracket 1 to the cleaning station to rinse the body of the medicine bottle 91. During the rinsing process, the valve between the air inlet 350 and the air source is opened, and the air chamber 31 covers the gap between the medicine bottle 91 and the cap 92 to prevent moisture from entering.

[0062] S6: After cleaning is completed, the mounting frame 1 is moved to the discharge station, and the drive assembly 4 drives a pair of clamps 3 to move to a separated state, and the medicine bottle 91 is placed at the discharge station.

[0063] Repeat steps S1 to S6 to achieve automatic cyclic operation.

[0064] In this embodiment, combined with Figures 6 to 8 As shown, the lower end of the medicine bottle 91 corresponding to the cap 92 is provided with an annular retaining flange 911 for limiting positioning. After the cap 92 is longitudinally pressed, it abuts against the annular retaining flange 911. The inner wall of the clamping surface of the corresponding clamping part 371 includes, from top to bottom, a first contact surface 3711 that fits against the side wall of the cap 92, a second contact surface 3712 that fits against the bottom of the annular retaining flange 911, and a third contact surface 3713 that fits against the side wall of the neck of the medicine bottle 91. When the cap 92 enters the cavity of the sleeve 93, and the cap 92 and the sleeve 93 are longitudinally tightly fitted, the lower edge of the sleeve 93 extends downward beyond the annular retaining flange 911. Therefore, after step S4 is executed, combined with Figure 10 As shown in the right figure, the cover 93 covers the lower end face of the annular flange 911.

[0065] In one embodiment, a heating module is provided inside the circular cavity 20, and the cover 93 is made of heat-shrinkable material. After step S4 is completed, the heating module works so that the cover 93 tightly wraps around the outside of the cover 92 and the annular flange 911.

[0066] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of the invention and should not be construed as limiting the scope of protection of the invention in any way. Based on this explanation, those skilled in the art can conceive of other specific embodiments of the invention without creative effort, and these embodiments will all fall within the scope of protection of the present invention.
