Description

Technical Field

[0001] The present invention relates to the technical field of medicine bottle clamping devices, and particularly to a capping type medicine bottle gripper. Background Art

[0002] Existing capping medicine bottle grippers, such as the gripping device and cleaning device for a medicament container with a cap disclosed in the Chinese invention patent with the application number 201510314018.3, work by clamping at the cap of the medicine bottle and wrapping the cap position of the medicine bottle through an air cavity, so as to block the intrusion of moisture between the bottle body and the cap when cleaning the medicine bottle through an air curtain.

[0003] Its disadvantages are as follows: The existing medicine bottle gripper cannot form a longitudinal pressure between the medicine bottle and the cap, resulting in the risk that the gas introduced into the air cavity invades the bottle body. Summary of the Invention

[0004] To overcome the above-mentioned deficiencies of the prior art, the present invention provides a capping type medicine bottle gripper, which can ensure that the cap is longitudinally pressed onto the medicine bottle to prevent the gas introduced into the air cavity from invading the medicine bottle.

[0005] To achieve the above object, the present invention is realized through the following technical solutions:

[0006] A capping type medicine bottle gripper for gripping a medicine bottle and sealing the cap at the upper end of the medicine bottle, comprising:

[0007] A pair of clamping blocks that can be driven to move to a state of being combined or separated. The clamping blocks are provided with clamping cavities and air cavities. When the pair of clamping blocks are in a combined state, the clamping cavity is used for clamping and circumferentially wrapping the position of the medicine bottle corresponding to the cap, and the pair of air cavities are combined to annularly wrap the outer periphery and the lower end of the cap;

[0008] A mounting bracket;

[0009] A pressing cap arranged between the pair of clamping blocks. The upper end of the pressing cap is provided with an extension rod, and the extension rod is floatingly installed on the mounting bracket longitudinally;

[0010] The clamping block is provided with a receiving cavity adapted to the pressing cap;

[0011] A transmission structure is provided between the pressing cap and the clamping block. During the process of the clamping block moving from the separated state to the combined state, the transmission structure is used to drive the pressing cap to move downward by a preset first distance to tightly press onto the upper end of the cap. At this time, the inner wall of the receiving cavity wraps around the radial outer side of the pressing cap, and the extension rod extends upward from the receiving cavity outside the clamping block.

[0012] Furthermore, in a capping type medicine bottle gripper in the present application, the clamping blocks are slidably installed on the mounting bracket in the horizontal direction, and the mounting bracket is provided with a driving component for driving the clamping blocks to move horizontally;

[0013] The transmission structure includes a pair of guiding inclined surfaces respectively located on the clamping block and the pressing cap. During the process of the clamping block moving towards the closed state, the guiding inclined surface on the clamping block abuts against the guiding inclined surface on the pressing cap to push the pressing cap downward by a preset first distance.

[0014] Furthermore, in a capping type medicine bottle gripper of the present application, the driving assembly includes a driving frame longitudinally slidably mounted on the mounting frame and a driver for driving the driving frame to move longitudinally relative to the mounting frame. A pair of clamping blocks are symmetrically slidably connected to the driving frame obliquely, so that during the longitudinal movement of the driving frame, it can drive a pair of clamping blocks to move synchronously in the opening and closing directions. As a preferred solution of the present application, based on the above device, it can drive a pair of clamping blocks to move in a linked manner in the opening and closing directions, having the advantage of simple control. When in the closed state, the driving force of the driver can be evenly distributed to a pair of clamping blocks to ensure the tight fit at the joint of the pair of clamping blocks, realizing the effective function of isolating water vapor, and also ensuring the consistency of the forces applied to the pressing cap by the transmission structures on both sides. Ensure the stability of the movement of the pressing cap.

[0015] Furthermore, in a capping type medicine bottle gripper of the present application, a pair of slide rails extending obliquely are provided on the driving frame, transmission rollers are provided on the clamping blocks, and a spring is provided between the clamping blocks and the mounting frame. The spring is used to apply an elastic force to the clamping blocks so that the transmission rollers abut against the slide rails; during the longitudinal movement of the driving frame, the slide rails can push the air chamber to move horizontally, realizing the synchronous movement of a pair of clamping blocks in the separating or closing directions. As a preferred solution of the present application, compared with the sliding connection of the slide rail slider, it has the advantage of good load-bearing performance, so as to improve the service life.

[0016] Furthermore, in a capping type medicine bottle gripper of the present application, the driver is a telescopic cylinder, and a limiting convex portion is provided at the end of the slide rail. When driving a pair of clamping blocks to separate, the limiting convex portion is used to limit the movement of the air chamber to limit the stroke of the driver. As a preferred solution of the present application, setting the limiting convex portion can ensure that the clamping blocks will not move out of position during the separating movement, and limit the movement stroke of the driver through the limiting convex portion, which has the advantages of simple control and cost saving compared with in-position detection by sensors.

[0017] Furthermore, in a capping type medicine bottle gripper of the present application,

[0018] A circular cavity adapted to the upper end of the cover body is provided at the bottom of the pressing cap;

[0019] The mounting frame is driven to move by a moving device;

[0020] Before a pair of clamping blocks are closed, move the mounting frame from top to bottom to sleeved the circular cavity on the upper end of the cover body;

[0021] It also includes a sensor, which is used to detect the displacement change of the pressure cap relative to the mounting bracket during the process of the circular cavity being sleeved on the cover body. As a preferred solution of this application, the disadvantages of the existing capping vial gripper also include that the centering positioning of the vial relative to the two side clamping blocks cannot be guaranteed before the two side clamping blocks move together, which will affect the sealing performance after the clamping blocks are combined. Based on the above device, its principle is: by moving the mounting bracket so that the circular cavity is sleeved on the cover body to ensure the position accuracy of the vial and the cover body. Since the pressure cap is floatingly mounted on the mounting bracket through the extension rod, if the position of the vial deviates, it will cause the outer edge of the cover body to abut against the circular cavity during the process of the mounting bracket moving to sleeve the circular cavity on the upper end of the cover body, causing the pressure cap to be lifted. Therefore, the sensor can judge whether the position of the vial is accurately positioned by detecting the displacement change of the pressure cap relative to the mounting bracket during this process. If the positioning error of the vial is too large to be sleeved into the circular cavity, the system will alarm and terminate the subsequent operation to avoid losses.

[0022] Further, in a capping vial gripper of this application, a mounting table is provided on the mounting bracket. The extension rod passes through the mounting table and is longitudinally slidably connected to the mounting table. A limit baffle is provided on the extension rod, and the limit baffle is located above the mounting table. A compression spring is abutted between the mounting table and the pressure cap, and the compression spring is sleeved on the extension rod. As a preferred solution of this application, the limit baffle is longitudinally abutted against the mounting table to limit the downward movement of the pressure cap before the pressure cap abuts against the cover body, and before the clamping blocks are combined. Based on the above device, during the process of the mounting bracket moving to longitudinally abut the pressure cap against the cover body, the pressure cap is lifted by a preset height h to make room for the downward displacement of the pressure cap during the combination of the clamping blocks. If the sensor detects that the height by which the pressure cap is lifted is greater than h, it indicates that the cover body has not entered the circular cavity, and it can be judged that the vial positioning is unqualified.

[0023] Further, in a capping vial gripper of this application, the sensor includes a Hall sensor and a magnetic block that are longitudinally opposed to each other. The Hall sensor and the magnetic block are respectively arranged on the limit baffle and the mounting table. As a preferred solution, it has the advantages of simple installation and low cost compared with an optoelectronic ranging sensor.

[0024] Further, in a capping vial gripper of this application, the clamping block includes:

[0025] A housing, a transverse partition is provided inside the housing, a transmission plate is arranged on the upper side of the transverse partition, and an air inlet is provided on the housing;

[0026] An air distribution cover installed inside the housing, the air distribution cover abuts against the lower end of the transverse partition, a split air flow channel is provided between the air distribution cover and the housing, the air inlet is communicated with the split air flow channel, and a group of air distribution outlets communicating the split air flow channel and the air cavity are provided on the air distribution cover;

[0027] The chuck is installed on the radial inner side of the air distribution cover. The chuck is integrally semi-circular. The chuck includes a clamping portion that abuts against the side wall of the medicine bottle and / or the cap, and a gas guiding portion located at the lower end of the clamping portion. The inner wall of the clamping portion encloses a clamping cavity. The air cavity includes an air inlet cavity located at the upper end of the clamping portion, an air outlet cavity located inside the gas guiding portion, and an air guiding groove provided on the inner wall of the clamping portion. The air guiding groove communicates the air inlet cavity and the air outlet cavity. As a preferred solution of the present application, in the present application, the material of the chuck is elastic plastic.

[0028] Furthermore, in a capping type medicine bottle gripper of the present application, a steam blocking groove is provided on the inner wall of the gas guiding portion. The steam blocking groove is semi-circular, and includes a tapered surface that is wider at the top and narrower at the bottom, and a horizontal semi-circular blocking surface at the upper end of the tapered surface. As a preferred solution of the present application, the steam blocking groove is used to block the rise of water vapor through the air outlet cavity.

[0029] It can be seen from the above technical solutions that the present invention has the following beneficial effects:

[0030] In a capping type medicine bottle gripper of the present application, after the clamping blocks are combined, the cap is clamped through the clamping cavity, and the air cavity covers the outer periphery and the lower end of the cap to block the intrusion of moisture when ventilating and blocking the medicine bottle during the cleaning process. During the process of the clamping blocks moving towards the combined direction, the pressing cap is driven to move to tightly press against the upper end of the cap through the transmission structure, which can ensure that the cap is longitudinally pressed onto the medicine bottle, prevent the gas introduced into the air cavity from intruding into the medicine bottle, and has the advantages of simple control and high stability.

[0049] Embodiment 1

[0050] Combined with Figures 1 to 3 A capping type medicine bottle gripper shown is used to grip the medicine bottle 91 and seal the cover body 92 at the upper end of the medicine bottle 91, and includes:

[0051] A pair of clamping blocks 3 that can be driven to move to a state of being engaged or separated. The clamping block 3 is provided with a clamping cavity 30 and an air cavity 31. When the pair of clamping blocks 3 are in the engaged state, the clamping cavity 30 is used to clamp and circumferentially wrap the position of the corresponding cap 92 of the medicine bottle 91, and the pair of air cavities 31 are combined to annularly cover the outer periphery and the lower end of the cap 92.

[0052] Mounting bracket 1;

[0053] 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 longitudinally on the mounting bracket 1.

[0054] The clamping block 3 is provided with a receiving cavity 32 adapted to the pressing cap 2.

[0055] 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 engaged 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 cap 92. At this time, the inner wall of the receiving cavity 32 covers the radial outer side of the pressing cap 2, and the extension rod 21 extends upward from the receiving cavity 32 to the outside of the clamping block 3.

[0056] Based on the above structure, in a capping type medicine bottle gripper in this embodiment, after the clamping blocks 3 are engaged, the cap 92 is clamped by the clamping cavity 30, and the air cavity 31 covers the outer periphery and the lower end of the cap 92 to block the intrusion of moisture when ventilating the medicine bottle 91 during the cleaning process. During the process of the clamping block 3 moving in the direction of engagement, the pressing cap 2 is driven by the transmission structure to move to tightly press against the upper end of the cap 92, which can ensure that the cap 92 is longitudinally pressed onto the medicine bottle 91 and prevent the gas introduced into the air cavity 31 from intruding into the medicine bottle 91.

[0057] Combined with Figure 2 and Figure 3 As shown, in this embodiment, the clamping block 3 is slidably mounted on the mounting bracket 1 in the horizontal direction, and the mounting bracket 1 is provided with a driving assembly 4 for driving the clamping block 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 engaged 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 bracket 1 is provided with a laterally extending first guide rail 11, and the clamping block 3 is slidably mounted on the first guide rail 11. Combined with Figure 8 As shown, in this embodiment, a transmission plate 33 is installed in the receiving cavity 32, and the guiding inclined surface 50 is provided on the transmission plate 33. Since the guiding inclined surface 50 on the clamping block 3 needs to be provided in the receiving cavity 32, and the grinding and processing of the receiving 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.

[0058] Combined with Figure 7As shown, in this embodiment, the driving assembly 4 includes a driving frame 41 longitudinally slidably mounted on the mounting frame 1 and a driver 42 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 in an oblique direction, so that the driving frame 41 can drive the pair of clamping blocks 3 to open and close synchronously during the longitudinal movement. Based on the above device, a pair of clamping blocks 3 can be driven to open and close in linkage, which has the advantage of simple control. In the engaged 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 joints of the pair of clamping blocks 3, to achieve an effective isolation effect of water vapor, and to ensure the consistency of the force applied to the pressing cap 2 by the transmission structures on both sides. Ensure the stability of the movement of the pressing cap 2. In this embodiment, a second guide rail 12 extending longitudinally is provided on the mounting frame 1, and the driving frame 41 is slidably mounted on the second guide rail 12. Combined with Figure 8 As shown, a sealing strip 34 is provided at the joint position of a pair of clamping blocks 3 .

[0059] In this embodiment, a pair of slide rails 411 extending obliquely 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, and 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 driving frame 41, the slide rail 411 can push the air cavity 31 to move horizontally, so as to realize the synchronous movement of a pair of clamping blocks 3 in the direction of separation or combination. Relative to the sliding connection of the slide rail slider, it has the advantage of good load-bearing performance to improve the service life. In this embodiment, the spring 52 is a tension spring, which is used to apply elastic force to the clamping block 3 to move in the direction of separation, the pair of slide rails 411 are in an eight-shaped shape, and the transmission roller 38 is a rolling bearing. In this embodiment, the driver 42 is a telescopic cylinder, and a limiting convex portion 412 is provided at the end of the slide rail 411. When driving a pair of clamping blocks 3 to separate, the limiting convex portion 412 is used to limit the movement of the air cavity 31 to limit the stroke of the driver 42. The limiting convex portion 412 can ensure that the clamping block 3 does not move over when moving away from each other. The limiting convex portion 412 limits the moving stroke of the driver 42, which has the advantages of simple control and cost saving compared to the in-position detection by the sensor. In this embodiment, the driving 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.

[0060] The existing capping medicine bottle clamp also has the disadvantage that the medicine bottle cannot be guaranteed to be centered relative to the clamps on both sides before the clamps on both sides move together, which may affect the sealing after the clamps are combined.

[0061] 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 adapted to the upper end of the cover body 92;

[0062] The mounting frame 1 is driven to move by a moving device (not shown);

[0063] Before the pair of clamping blocks 3 are combined, move the mounting bracket 1 from top to bottom to sleeved the circular cavity 20 on the upper end of the cover body 92;

[0064] It further includes a sensor for detecting the displacement change amount of the pressure cap 2 relative to the mounting bracket 1 during the process of sleeving the circular cavity 20 on the cover body 92.

[0065] Based on the above device, its principle is: by moving the mounting bracket 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 pressure cap 2 is floatingly mounted on the mounting bracket 1 through the extension rod 21, if the position of the medicine bottle 91 deviates, it will cause that during the process of moving the mounting bracket 1 to sleeve the circular cavity 20 on the upper end of the cover body 92, the cover body 92 abuts against the outer edge of the circular cavity 20, causing the pressure cap 2 to be 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 pressure cap 2 relative to the mounting bracket 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.

[0066] Combined with Figure 2 and Figure 5 As shown, in this embodiment, a mounting table 13 is provided on the mounting bracket 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 abuts between the mounting table 13 and the pressure cap 2. The compression spring 53 is sleeved on the extension rod 21. Before the pressure cap 2 abuts against the cover body 92, the limit baffle 22 longitudinally abuts against the mounting table 13 to limit the downward movement of the pressure cap 2. Before the clamping blocks 3 are combined. Based on the above device, during the process of moving the mounting bracket 1 until the pressure cap 2 longitudinally abuts against the cover body 92, the pressure cap 2 is lifted by a preset height h to make room for the downward displacement of the pressure cap 2 during the combination of the clamping blocks 3. If the height that the sensor detects the pressure cap 2 is lifted is greater than h, it indicates 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.

[0067] Combined with Figure 2 As shown, in this embodiment, the sensor includes a Hall sensor 61 and a magnetic block 62 facing longitudinally. 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 photoelectric distance measuring sensor. In this embodiment, a limit groove 132 is provided on the mounting table 13. The extension rod 21 passes through 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.

[0068] Combined withFigure 3 , Figure 6 and Figure 8 As shown in ,

[0069] , in this embodiment, the clamping block 3 includes:

[0069] A housing 35, inside which a transverse partition 351 is provided. The 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;

[0070] 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;

[0071] A chuck 37, 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 abutting 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 respectively, an air outlet cavity 312 located inside the gas guiding portion 372, and an air guiding groove 313 provided on the inner wall of the clamping portion 371. The air 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.

[0072] Combined with Figure 4 As shown, 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.

[0073] Combined with Figure 9 As shown, in this embodiment, a first annular flange 23 and a second annular flange 24 are provided at the bottom of the pressure cap 2. 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 pressure 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 cap body 92 and the mouth of the medicine bottle 91 fit tightly at the inner and outer diameter positions to improve the sealing performance.

[0074] In other embodiments, it is necessary to press-fit a sealing sleeve 93 on the cap body 92. The sleeve cavity of the sealing sleeve 93 is adapted to the shape of the upper end of the cap body 92. After the sealing sleeve 93 is covered on the cap body 92, the first annular flange 23 and the second annular flange 24 can press the sealing sleeve 93 on the cap body 92.

[0075] Embodiment 2

[0076] On the basis of Embodiment 1, in this embodiment, in combination with Figure 9 As shown, a suction cup 25 is provided on the press 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 through the press 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 body 92, and then the clamping block 3 is driven to move to fit together, and the envelope 93 is tightly pressed on the cover body 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 capping type medicine bottle gripper can also transfer the envelope 93 and press the envelope 93 on the cover body 92, having the advantage of high integration. Its usage method includes the following steps:

[0077] S1: A 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 the envelope 93 is sucked by the suction cup 25;

[0078] S2: In combination with Figure 10 As shown in the left to middle figures 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 body 92 enters the sleeve cavity of the envelope 93. During this process, the press 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 body 92, and avoid the longitudinal non-tight fitting of the envelope 93 and the cover body 92 caused by the friction between the side surfaces of the envelope 93 and the cover body 92;

[0079] S3: The sensor detects whether the press cap 2 rises a preset height h relative to the mounting bracket 1 in step S2. If the rising height of the press 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 press cap 2 is equal to h, step S4 is executed;

[0080] S4: In combination with Figure 10 As shown in the right figure of, the driving assembly 4 drives a pair of clamping blocks 3 to move to a fitting state. At this time, the medicine bottle 91 is clamped, and the envelope 93 is tightly pressed on the cover body 92;
