An example configuration of the ampoule cutter 3 will be described below with reference to fig. 6A to 6D. When the carrier 11 reaches the cutting station a2, the ampoule cutting device 3 cuts the neck of the ampoule.

Referring to fig. 6C, the ampoule cutting device 3 includes a cutting drive unit 31 and a cutting member 32. The cutting member 32 comprises a cutting blade 321 and is arranged to be movable in a cutting movement direction D1, the cutting blade 321 being adapted to cut the neck of the ampoule B. The ampoule cutting device 3 further comprises a base frame 30 and a cutting transmission mechanism. The cutting driving unit 31 is mounted to the base frame 30, and the cutting driving unit 31 outputs a rotational motion through an output shaft and drives the cutting member 32 to reciprocate in the cutting moving direction D1 through a cutting transmission mechanism.

In the figure, the cutting drive unit 31 is a motor, such as a stepping motor or a servo motor or the like. For the motor, the output shaft 311 of the cutting drive unit 31 is the motor shaft of the motor. The cutting drive unit 31 is mounted such that the axial direction D2 of the output shaft 311 is perpendicular to the cutting movement direction D1.

Referring to fig. 6A and 6B, the cutting transmission mechanism includes a chute member 31a and a slider 31B, and the slider 31B is inserted into the chute member 31a and is slidable in the chute member 31 a.

The slider 31b is provided on the turntable 312 and is offset from the central axis of the turntable 312, and the turntable 312 is connected to the output shaft 311 of the cutting drive unit 31, and the central axis of the turntable 312 is coaxial with the axis of the output shaft 311. Under the driving action of the cutting drive unit 31, the output shaft 311 rotates, which rotates the turntable 312 about the central axis, so that the slider 31b rotates about the central axis of the turntable, i.e., the axis of the output shaft 311. The chute member 31a is provided to the cutting member 32. The chute extending direction of the chute member 31a is different from the output axis direction D2 of the output shaft 311 and different from the cutting moving direction D1, and since the sliding member 31b is offset from the central axis of the turntable 312, i.e. from the axis of the output shaft 311, when the sliding member 31b rotates, the sliding member 31b will displace the chute member 31a in the cutting moving direction D1, so as to move the cutting member 32 in the cutting moving direction D1. In the illustrated embodiment, the extending direction of the chute member 31a is perpendicular to the axial direction D2 of the output shaft 311, and the extending direction of the chute member 31a is perpendicular to the cutting movement direction D1, that is, in fig. 6A and 6B, the chute of the chute member 31a extends in a direction perpendicular to the paper surface. Alternatively, the slide is provided on the cutting member 32 and the chute member is provided on a member connected to the second drive unit. That is, a first one of the chute member and the slider is provided to be connected to the output shaft 311 of the cutting drive unit 31, and a second one of the chute member and the slider is provided to be connected to the cutting member 32, the first one being provided at a position offset from the axis of the output shaft 311 of the cutting drive unit 31; under the driving action of the cutting driving unit 31, the first side is driven by the output shaft 311 to rotate around the axis of the output shaft 311, and the second side is driven by the first side to reciprocate along with the cutting member 32 in the cutting moving direction D1. The slider 31b may be a cylindrical body, and the outer circumferential surface of the cylindrical body is engaged with the chute member 31a, thereby reducing friction, so that the slider 31b slides more smoothly in the chute member 31 a.

As can be seen with reference to fig. 6A to 6C, the base frame 30 further has a guide rail 301 extending in the cutting movement direction D1, and the cutting member 32 is disposed on the base frame 30 via the guide rail 301. In the illustrated embodiment, the guide rail 301 is a guide rib extending in the cutting moving direction D1, and the cutting member 32 has a guide groove (not illustrated) extending in the cutting moving direction D1. Alternatively, the guide rail 301 may be a guide groove, and the cutting member 32 has a guide rib engaged therewith.

The side surface of the guide protrusion engaged with the guide groove may have a lateral concave portion depressed inward, and correspondingly, the side surface of the guide groove engaged with the guide protrusion may have a lateral convex portion protruding outward, thereby forming a hooking function, so that the guide rail 301 and the cutting member 32 are not easily separated. The guide rib may also be arranged to have a dimension at the bottom towards the guide groove that is greater than a dimension at the top away from the guide groove, thus also providing a hooking action such that the guide rail 301 is not easily disengaged from the cutting member 32.

Referring to fig. 6C and 6D, the cutting blade 321 may be a cutter wheel rotatably provided to the cutting member 32. Ampoule is glass product ratio brittleness usually, and when the cutting ampoule, ampoule rotation, the break bar also followed and changes, can reduce frictional force, is difficult to contort the break bar to increase the life of break bar, in addition, more for mitigateing with ampoule's contact, can prevent to cause other harm to ampoule.

Referring to fig. 6C, the ampoule cutting device 3 further includes a dust suction pipe 33. The suction tube 33 removes debris formed when the ampoule is cut by suction. The suction opening of the suction tube 33 is close to the cutting blade 321 and faces the junction of the body and the head of the ampoule bottle. The suction pipe 33 may be provided on the cutting member 32 to move together with the cutting member 32.

The ampoule cutting apparatus 3 further comprises a germicidal lamp 34 for sterilizing. The sterilizing range of the sterilizing lamp 34 covers the working area of the cutting blade 321, thereby sterilizing the ampoule when the ampoule is cut. The ampoule cutting apparatus 3 further includes a photoelectric sensor 333 for detecting whether the cutting unit 32 has returned to its original position after cutting the ampoule.

The cutting driving unit 31 is started, the output shaft 311 rotates around the axis thereof under the driving action of the cutting driving unit 31, the turntable 312 is driven to rotate, and the sliding member 31b arranged on the turntable 312 is driven to rotate around the axis of the output shaft 311, and the sliding groove member 31a and the cutting member 32 are driven to reciprocate in the cutting moving direction D1 along with the rotation of the sliding member 31b because the sliding member 31b deviates from the axis of the output shaft 311. Due to the limiting effect of the guide rail 301 on the cutting member 32, the cutting member 32 can only move along the cutting moving direction D1, so that the sliding piece 31b slides along the sliding groove piece 31a at this time, so to speak, the sliding groove piece 31a provided on the cutting member 32 absorbs the movement of the sliding piece 31b in the direction perpendicular to the cutting moving direction D1, so that the movement of the sliding piece 31b along the cutting moving direction D1 drives the cutting member 32 to move along the cutting moving direction D1, so that the knife edge of the cutting blade 321 contacts the neck of the ampoule bottle, specifically, the melted seal of the ampoule bottle. Therefore, when the ampoule bottle is rotated by the carrier rotating mechanism 24 described above, the cutting blade 321 of the cutting member 32 cuts along the entire circumference of the bottle neck, forming a cut mark. At the same time, the suction tube 33 and the germicidal lamp 34 act to remove debris from the cut ampoule and to sterilize the ampoule and the surrounding environment.

The ampoule cutting device 3 may be provided at the cutting station a2 as shown in fig. 1, and may be provided to be detachably included in the ampoule processing apparatus 100. That is, when the cutting operation is required, the ampoule cutting device 3 is delivered to the corresponding position of the cutting station a2 by the corresponding driving action, and when the cutting operation is not required, the ampoule cutting device 3 is removed.

The ampoule processing apparatus 100 further includes an ampoule disinfecting device 4. The ampoule disinfecting device 4 is disposed at the disinfecting station a 3. When the ampoule reaches the sterilization station A3, the ampoule sterilization device 4 sterilizes the neck of the ampoule, as described above, the sterilization station A3 being between the cutting station a2 and the bottle severing station a 4. An example configuration of the ampoule bottle sterilizing device 4 will be described below with reference to fig. 7A to 7C.

As shown in fig. 7A to 7C, the ampoule bottle sterilizing apparatus 4 includes a sterilizing string 41 (also shown in fig. 1) and a sterilizing liquid supply portion 43, the sterilizing string 41 holds a sterilizing line 48, the sterilizing line 48 is for contacting a neck of the ampoule bottle, and the sterilizing liquid supply portion 43 is for supplying a sterilizing liquid to the sterilizing line 48. The sterilization clamp 41 is movably mounted to the support housing 44 and is also removable from the support housing 44 by opening the cover 444. Fig. 1 and 7A both show another sterilization clamp 41a, which is used for sterilization of penicillin bottles and is not related to the design, and thus is not described in detail herein.

Fig. 7B to 7C show the configuration of the sterilization wire clip 41, and fig. 7B does not show the sterilization wire 48. The sterilization string clamp 41 includes a sterilization string 48, a storage case 411, a string-releasing reel 412, a string-receiving reel 413, a driving roller 414, a cycloid roller 415, a wiping guide wheel 416, a buffer spring 416a, and a transition guide wheel 417. In the illustrated embodiment, a transition roller 418 is also provided between the payout reel 412 and the drive roller 414 in the winding path of the sterilizing wire 48. The sterilization thread 48 may be cotton thread or may be selected according to the actual situation. Wherein the sterilization line segment between wiper guide 416 and transition guide 417 is the working line segment that contacts the ampoule, which is defined as the working position of sterilization line 48. The sterilization thread clamp 41 is installed such that the working thread section of the sterilization thread 48 extends in the horizontal direction, as shown in fig. 1.

The storage case 411 has a first through hole 421, a second through hole 431, a third through hole 441, and a fourth through hole 451 formed on a side surface thereof, respectively. According to the direction of fig. 7C, the first through hole 421 is close to the lower side, the second through hole 431 is close to the upper side and opposite to the first through hole 421, the third through hole 441 is close to the right side, and the fourth through hole 451 is close to the left side and opposite to the third through hole 441. The unwinding reel 412 is provided in the storage case 411 and rotates around a center axis 422 matching the first through hole 421, and the unwinding reel 412 is configured to release the sterilizing thread 48 wound around the unwinding reel 412 by rotation. The take-up reel 413 is rotated about a center axis 432 coinciding with the second through hole 431 in the storage case 411, and the take-up reel 413 is used for taking up the sterilizing thread 48 released from the thread take-up and release reel 412 by rotating. The central shaft 422 and the central shaft 432 may pass through the first through hole 421 and the second through hole 431, respectively, and the wire releasing reel 412 and the wire retrieving reel 413 are sleeved on the central shaft 422 and the central shaft 432, respectively. Similarly, the driving roller 414 is disposed in the storage box 411 and rotates around a central axis coinciding with the third through hole 441, the driving roller 414 is used for winding the disinfection line 48 released from the take-up and pay-off reel 412 by one turn (the number of turns can be adjusted according to practical conditions, but is not too large), and the driving roller 414 is also used for guiding and transmitting the wound disinfection line 48 to the wiping guide wheel 416. In the figure, the sterilizing line 48 released from the pay-off reel 412 is more stabilized by passing through the transition roller 418 and then winding around the drive roller 414. The thread take-up roller 415 rotates about a central axis coinciding with the fourth through hole 451 in the storage case 411, and feeds the sterilizing thread 48 to the thread take-up reel 413. In one embodiment, a wire adjusting wheel may be movably sleeved on the cycloid roller 415, and the wire adjusting wheel reciprocates along the extending direction of the cycloid roller 415 (the thickness direction of the storage box 411, or the direction perpendicular to the paper surface in fig. 7C) along with the rotation of the cycloid roller 415, for example, the wire adjusting wheel is sleeved on the cycloid roller 415 by a threaded engagement, similar to a lead screw nut. In this way, while the disinfection wire 48 passing through the transition guide wheel 417 is guided and conveyed to the take-up reel 413, the winding position of the disinfection wire 48 on the take-up reel 413 can be adjusted by the reciprocating movement of the wire adjusting wheel, so that the disinfection wire 48 is uniformly wound on the take-up reel 413.

Referring to fig. 7C, a wiping guide wheel 416 is disposed at a right corner position of the top of the storage box 411, the wiping guide wheel 416 is used for guiding and transmitting the sterilization line 48 released by the driving roller 414 to a transition guide wheel 417 and also used for contacting the sterilization line 48 to the medicine bottle to be sterilized, and a buffer spring 416a is further disposed between the wiping guide wheel 416 and the storage box 411, and when the sterilization line 48 contacts to the medicine bottle to be sterilized, the buffer spring 416a is used for buffering. A transition guide wheel 417 is provided at a left side corner position of the top of the storage box 411, and the transition guide wheel 417 is used for guiding and transmitting the sterilization thread 48 passing through the wiping guide wheel 416 to the cycloid roller 415. The working line segments of sterilization line 48 are supported by wiping guide 416 and transition guide 417.

The storage box 411 is further provided with a first guide groove 461 and a second guide groove 462, two ends of the first guide groove 461 respectively lead to the positions of the driving roller 414 and the wiping guide wheel 416, two ends of the second guide groove 462 respectively lead to the positions of the transition guide wheel 417 and the cycloid roller 415, and the first guide groove 461 and the second guide groove 462 are used for guiding the conveying direction of the disinfection line 48.

In this embodiment, the new disinfection line 48 is released from the pay-off reel 412, passes through the transition roller 418 to reach the driving roller 414, and is transported to the wiping guide roller 416 through the driving roller 414, after disinfection use, the used disinfection line 48 is wound on the take-up reel 413 through the transition guide roller 417 and the cycloid roller 415 to complete recycling, after all use, the used disinfection line 48 on the take-up reel 413 is taken out, and the new disinfection line 48 is wound on the pay-off reel 412 again, or the pay-off reel 412 wound with the new disinfection line can be directly replaced.

In this embodiment, the side surface of the storage box 411 is further provided with a first observation hole 471 and a second observation hole 472 respectively for observing the remaining amount or the winding condition of the disinfection thread 48 on the pay-off reel 412 and the take-up reel 413 respectively.

The ampoule disinfecting device 4 may further comprise a retraction drive unit (not shown), which may be, for example, one or more motors. In one embodiment, after the sterilization clamp 41 is fully inserted into the support housing 44, the take-up and take-up driving unit drives the take-up reel 413 and the driving roller 414 to rotate, the take-up reel 413 and the driving roller 414 can be driven to rotate simultaneously through a suitable transmission mechanism, so that the take-up and take-up linear speed of the sterilization wire 48 can be uniformly controlled, and the rotation of the take-up reel 413 can be limited by limiting the rotation of the driving roller 414. The pay-off reel 412 can be driven to rotate following the rotation of the drive roller 414 without the driving of the drive unit.

The disinfectant supplying section 43 may include a disinfectant dropper 433, a disinfectant storage bottle 432, and a disinfectant supply pump (not shown). The nozzle of the disinfectant dropper 433 is disposed at a position facing the wiping guide 416, and is used to drop disinfectant to the disinfection wire 48, so that the disinfectant wets the disinfection wire 48 at the wiping guide 416. The disinfectant liquid supply pump pumps the disinfectant liquid stored in the disinfectant liquid storage bottle 432 to the disinfectant liquid dropper 433 through the pipeline. During the retraction and extension of the disinfection line 48, the disinfection line segment that is about to reach the working position passes through the wiping guide wheel 416, so that the disinfection solution dripping from the drip nozzle is more uniformly distributed on the working line segment of the disinfection line 48 that reaches the working position.

The ampoule disinfecting device 4 further comprises a moving drive mechanism (not shown) for moving the disinfecting grip 41 (in the embodiment, in a horizontal direction) to a position where the disinfecting line 48 is aligned with the neck of the ampoule. The movement driving mechanism may include a movement driving unit such as a motor and a movement transmission mechanism, and the movement transmission mechanism may be a linearly-driven lead screw nut or the like.

Ampoule breaking device 5

The ampoule-bottle handling apparatus 100 further includes an ampoule-bottle breaking device 5. When the carrier 11 reaches the bottle breaking station a4, the ampoule bottle breaking device 5 breaks the head of the ampoule bottle. An example configuration of the ampoule bottle breaking device 5 will be described below with reference to fig. 8A to 8C.

The ampoule-breaking device 5 includes a bottle-breaking driving unit 51 and a swing arm 52. The bottle-breaking driving unit 51 outputs a rotational motion through an output shaft 51 a. The swing arm 52 is connected to an output shaft 51a of the bottle-breaking drive unit 51, and the swing arm 52 swings by the driving action of the bottle-breaking drive unit 51.

Referring to fig. 8A and 8B, the swing arm 52 includes a free end 522 for breaking off the head of the ampoule bottle and a fulcrum end 521 opposite to the free end 522. The pivot end 521 of the swing arm 52 has a hole portion 52a, the output shaft 51a of the bottle-breaking drive unit 51 passes through the hole portion 52a, the pivot end 521 branches from the hole portion 52a into two end walls 521a, 521b, and the hole portion 52a and the output shaft 51a can be clamped by a fastener such as a bolt (not shown in the figure) passing through the two end walls 521a, 521b, respectively. In the illustrated embodiment, the bottle severing drive unit 51 is a motor, the output shaft 51a is a motor shaft, and the fulcrum end of the swing arm 52 is connected to the motor shaft of the motor. The swing arm 52 may be externally fitted with a cover shell made of a soft material such as fabric, and the cover shell and the swing arm 52 may be fixed by providing hole portions in the cover shell and the swing arm 52, respectively, and then fastening members through the corresponding hole portions. The ampoule-breaking-off device 5 further includes a base frame 53, and the bottle-breaking-off driving unit 51 is mounted to the base frame 53. As shown in fig. 8C, the base frame 53 includes two standing plates 53a, 53b, and the swing arm 52 is located between the two standing plates 53a, 53 b. Each of the vertical plates is an L-shaped plate including a vertical portion and a horizontal portion protruding from an upper portion of the vertical portion toward one side of the ampoule bottle, and the bottle-breaking driving unit 51 is mounted to the horizontal portion.

The ampoule bottle breaking device 5 further comprises a bottle breaking measurement and control system, and the bottle breaking measurement and control system comprises an in-position control module, an original point detection module and an in-position detection module. The in-position control module is configured to detect whether the ampoule bottle is located at the bottle breaking position and send a bottle breaking control signal to the bottle breaking driving unit 51. The origin detection module is configured to detect whether the swing arm 52 is located at the origin position and send an origin signal to the bottle-breaking driving unit 51. The in-position detecting module is configured to detect whether the swing arm 52 is in the in-position and send an in-position signal to the bottle-breaking driving unit 51. The home position is a predetermined position of the swing arm 52 when the swing arm 52 is in the non-operating state, and the home position is a predetermined position at which the swing arm 52 does not swing any more after breaking off the head of the ampoule bottle. For example, when the swing arm 52 is located at the origin position, the swing arm 52 is in a horizontally extended state. In the illustrated embodiment, the seating control module may determine whether the carrier 11 holding the ampoule is located at the bottle breaking-off station a4 by determining the rotation angle of the turntable 21 in the station switching device 2 through the rotation driving unit 221.

Referring to fig. 8C, the ampoule breaking device 5 includes a sensor mask 57, a home sensor 58, and a position sensor 59. The sensor mask 57 is attached to the swing arm 52 and changes its position in accordance with the swing of the swing arm 52. The origin sensor 58 is mounted on the base frame 53 at a position corresponding to the origin position of the ampoule bottle, and the origin sensor 58 senses the sensor mask 57 when the swing arm 52 is located at the origin position. The seating sensor 59 is mounted on the base frame 53 at a position corresponding to the seating position of the ampoule bottle, and when the swing arm 52 is located at the seating position, the seating sensor 59 senses the sensor mask 57. The origin sensor 58 and the sensor mask 57 constitute an origin detection module, and the in-position sensor 59 and the sensor mask 57 constitute an in-position detection module.

The ampoule bottle breaking device 5 further comprises a bottle head collecting box 54, and the bottle head collecting box 54 is used for collecting broken bottle heads. After the swing arm 52 breaks the bottle heads, the bottle heads fall into the head collection box 54 in the direction indicated by the arrow C1 in fig. 8B. The stub collection box 54 may be removably mounted to the base frame 53, such as by fasteners. The tip collection box 54 may include a pull handle 543 to facilitate removal from the base 53. The head collection box 54 includes a collection port 541, and a section 541a of the collection port 541 is inclined downward toward the ampoule. The stub collection box 54 may further include a lower outlet 542 (shown in fig. 8C) at a lower portion thereof, so that the broken stubs can be easily circulated to other portions through the lower outlet 542.

Release the driving mechanism 6

Referring to fig. 3A, the ampoule handling apparatus 100 further includes a release drive mechanism 6, and when the carrier 11 reaches the release station a5, the release drive mechanism 6 causes the carrier 11 to release the ampoule. The structure of the unclamp driving mechanism 6 may be the same as that of the clamp driving mechanism 12, as shown in fig. 3B, except that the rotation direction of the output shaft of the clamp driving unit that drives the drive shaft to rotate in the unclamp driving mechanism 6 is opposite to the rotation direction of the output shaft 18a of the clamp driving unit 18 in the clamp driving mechanism 12, thereby achieving a unclamping action opposite to clamping.

Overall construction and control

The structure of each part is described above generally in conjunction with the drawings, and the overall configuration and control of the ampoule bottle handling apparatus 100 will be described next.

Referring to fig. 2A, the turntable 21 is an eight-index turntable, and eight carriers 11 are uniformly distributed. A gripper drive 12 is provided at the gripping station a1, which cooperates with the carrier 11 to grip the ampoule. At the cutting station a2, a carrier rotating mechanism 24 and an ampoule cutting device 2 (not shown in fig. 2A) are provided, which cooperate with the carrier 11, to cut the neck of the ampoule. Another carrier rotating mechanism 34 and an ampoule disinfecting device 4 (not shown in fig. 2A) cooperating with the carrier 11 are provided at the disinfecting station A3 to disinfect the neck of the ampoule, and a disinfecting station A3 is interposed between the cutting station a2 and the bottle breaking-off station a 4. An ampoule breaking device 5 (not shown in fig. 2A) cooperating with the carrier 11 is provided at the breaking station a4 to break the head of the ampoule. At the release station a5, a release drive mechanism 6 (see fig. 3A) is provided that engages the carrier 11 to cause the carrier 11 to release the ampoule. The figure also shows: station a11 between the cutting station a2 and the sanitizing station A3, station a12 between the bottle severing station a4 and the releasing station a5, and station a13 between the releasing station a5 and the gripping station a 1. Stations a11, a12 and a13 may be used for handling other vials, may be used as other handling stations for ampoules, or may be an idle station to prevent interference between devices in adjacent stations, for example, station a12 may be provided with a mechanism for detecting the state of the ampoule, station a13 may be an idle station to provide space for a mechanism for placing ampoules in the clamping station a1 and a mechanism for removing ampoules in the release station a5, or a sensor may be added at station a13 to detect whether the carrier 11 is released to the maximum. Therefore, it is not described in detail herein. The action of multiple stations on their respective vials can be performed simultaneously, thereby improving efficiency.

The following describes the operation procedure of an ampoule and a corresponding carrier 11.

An upstream placement mechanism places the ampoule on carrier 11 at clamping station a 1. The lifting driving unit 19 drives the transmission shaft 17 to move upwards to be in transmission connection with the rotating body 14 of the carrier body 11 of the carrier 11, and then the clamping driving unit 18 drives the transmission shaft 17 to drive the rotating body 14 to rotate, so that the clamping pieces 15 of the carrier 11 clamp the ampoule bottles. After the ampoule bottle is clamped, the lifting driving unit 19 drives the transmission shaft 17 to move down to the original position, and then the rotary driving mechanism 22 drives the rotary table 21 to rotate the carrier 11 mounted on the rotary table 21 to the next station, i.e. the cutting station a 2.

At the cutting station a2, the carrier 11 is engaged with the rotary guide 241 of the carrier rotating mechanism 24, and under the driving action of the rotary driving unit 242, the rotary guide 241 drives the carrier 11 to rotate relative to the turntable 21, and at this time, the cutting driving unit 31 of the ampoule bottle cutting device 3 drives the cutting component 32 to cut the bottleneck of the ampoule bottle. After the cut mark is formed, the cutter member 32 moves back to the home position, and the rotary guide 241 returns to the state of engaging with the annular guide 231. The turntable 21 rotates to bring the carrier 11 to the next station, i.e. the sterilization station a 3.

At disinfection station A3, carrier 11 block is to carrier rotary mechanism 34, and is rotatory under the drive effect of carrier rotary mechanism 34, and the disinfection line 48 that distributes the antiseptic solution contacts the bottleneck of ampoule, thus can disinfect to the whole periphery of bottleneck. After the sterilization is completed, the turntable 21 is rotated to rotate the carrier 11 to the next station, i.e., the bottle breaking-off station a4, and the moving driving mechanism returns the sterilizing clamp 41 to the origin position to wait for the next operation.

At the bottle breaking station a4, the bottle breaking driving unit 51 of the ampoule bottle breaking device 5 drives the swing arm 52 to swing so as to break the head of the ampoule bottle, and the swing arm 52 swings to the home position and thereafter swings back to the original position. After the swing is completed, the turntable 21 is rotated to rotate the carrier 11 to the next station, i.e., the release station a 5.

At release station a5, release of the drive mechanism 6 causes the carrier 11 to release the ampoule.

In addition, since the plurality of stations operate simultaneously, the rotation driving mechanism 22 drives the rotary table 21 to rotate only after the operation of each station is determined to be completed and the corresponding component returns to the original position, and the rotary table 21 rotates by a predetermined angle each time (in the illustrated embodiment, the predetermined angle is 45 degrees and is integral corresponding to eight stations).

At the clamp station a1, the clamp drive unit 18 of the clamp drive mechanism 12 may be a servo motor. This servo motor can drive holder 15 along radial movement under the torque mode thereby press from both sides tight ampoule, servo motor stops work promptly when servo motor's output torque exceeds predetermined moment of torsion, and, thereby, the number of revolutions through reading the encoder information in the servo motor obtains servo motor calculates the displacement distance who reachs holder 15, thereby whether check with ampoule when pressing from both sides that holder 15 should have the predetermined displacement distance conform and judge whether press from both sides tightly, check that information is errorless confirm promptly and press from both sides tightly, lift drive unit 19 drives transmission shaft 17 and moves down to the primary point position. If the check information is wrong, the system reports the wrong, and the ampoule bottle is not clamped or placed correctly.

At the cutting station a2, the cutting driving unit 31 of the ampoule cutting device 3 may be a servo motor, the servo motor may drive the cutting member 32 in a torque mode, when the output torque of the servo motor exceeds a predetermined torque, it is determined that the cutting member 32 abuts against the ampoule, the rotary driving unit 242 of the carrier rotating mechanism 24 drives the rotary guide 241 to rotate the carrier 11 for a predetermined number of turns and then stops at the origin, and the above description is further confirmed by the photoelectric sensor 245 as to whether the carrier 11 stops at the origin. Upon completion of the cutting action, the servomotor serving as the cutting drive unit 3 is reversed to move the cutting member 32 back to the home position, and the determination by the photoelectric sensor 333 as to whether or not to move back to the home position is made as described above.

In the disinfection station a3, the movable driving mechanism sends the disinfection clamp 41 to the ampoule bottle, in the sending process, under the driving action of the retracting and releasing driving unit, the driving roller 414 rotates, so that the disinfection wire section used in the previous operation is transferred to the wire take-up reel 413, and the new disinfection wire section is sent to the working position, and meanwhile, the disinfection liquid supply pump sends the extracted disinfection liquid to the disinfection liquid dropper 433 so as to drip on the new disinfection wire section, so that the disinfection liquid is uniformly distributed on the disinfection line 48, and after the disinfection clamp 41 reaches a predetermined position where the disinfection line 48 can contact the bottleneck of the ampoule bottle to be sent, the position sensor can be arranged, so that the disinfection clamp 41 is sensed to be moved to the position, and a stop signal is sent to the movable driving mechanism. And at this time, the carrier 11 containing the ampoule is engaged with the carrier rotating mechanism 34, and the ampoule is rotated by the driving action of the carrier rotating mechanism 34 following the carrier 11, so that the entire periphery of the bottle neck can be sterilized. After the disinfection is finished, the driving mechanism is moved to move the disinfection clamp 41 back to the original position.
