Description

Technical Field

[0001] The present invention relates to the technical field of automatic packaging equipment for medicine bottles, and particularly relates to an automatic packaging device and packaging method for cefamandole nafate for injection medicine bottles. Background Art

[0002] Cefamandole nafate for injection is mainly used for the treatment of diseases such as pulmonary infections, urinary tract infections, biliary tract infections, skin and soft tissue infections, bone and joint infections, septicemia, and abdominal infections caused by sensitive bacteria. When using it, it needs to be used strictly according to the dosage.

[0003] After the cefamandole nafate for injection powder is produced, it needs to be filled into vials of different specifications and packaged. Currently, there are mainly two model specifications of cefamandole nafate for injection, which are 0.5g and 1g respectively, and the sizes of the corresponding vials used are different. During production, usually two automated production lines are set up to produce cefamandole nafate for injection of 0.5g and 1g specifications respectively. In this way, on the one hand, when setting up the production line, two or even more complete production lines are required, increasing the cost of setting up the production line and also increasing the occupied area; on the other hand, when it is necessary to produce cefamandole nafate for injection of other specifications, it is also difficult to modify the existing production line, and adding new production lines also leads to an increase in cost, so there is a need for improvement. Summary of the Invention

[0004] The first object of the present invention is to provide an automatic packaging device for cefamandole nafate for injection medicine bottles, and its advantage is that it can meet the production requirements of cefamandole nafate for injection of different specifications, reduce the cost of setting up the production line, and reduce the occupied area.

[0005] The above technical object of the present invention is achieved through the following technical solutions: an automatic packaging device for cefamandole nafate for injection medicine bottles, including a medicine bottle filling device for automatically filling cefamandole nafate for injection powder into vials and sealing them, and the medicine bottle filling device is provided with an output assembly line; several groups of the medicine bottle filling devices are arranged in parallel to produce cefamandole nafate for injection of different specifications, and the output assembly lines of several groups of the medicine bottle filling devices converge at a medicine bottle convergence assembly line. At the end of the medicine bottle convergence assembly line far from the medicine bottle filling device, several medicine bottle screening lines are arranged in a stepped manner along the vertical direction to screen out medicine bottles in descending order. At the output end of the medicine bottle screening line, a medicine bottle rotating and conveying device and a medicine bottle packing device are fixedly provided. The medicine bottle rotating and conveying device is rotationally connected with several medicine bottle conveying disks coaxially along the vertical direction.

When the sorting motor drives the abutting plates to rotate to a parallel position, the distance between the abutting plates is equal to the diameter of the concave groove of the corresponding-sized vial, and at the same time, it is greater than the maximum diameter of the body of a smaller-sized medicine bottle.

[0008] The present invention is further configured such that: the sorting plate is arranged obliquely downward along the conveying direction of the medicine bottle screening line, and a pressure sensor for sensing the total weight of the medicine bottles on the sorting plate is fixedly provided at one end of the abutting plate close to the rotating portion.

[0009] The present invention is further configured such that: the diameter of the medicine bottle conveying disk gradually decreases from top to bottom in the vertical direction. A rotating hole is provided at the center position of the medicine bottle conveying disk, and at the same time, a pin slot is provided in the rotating hole. The number of the pin slots corresponds to the medicine bottle sorting assembly one by one. At the same time, a plurality of positioning columns are evenly and fixedly provided around the rotating hole at both ends of the medicine bottle conveying disk. The driving assembly includes a fixedly provided driving motor. A hollow rotating column is coaxially and fixedly provided on the rotating shaft of the driving motor. The diameter of the hollow rotating column is smaller than the diameter of the rotating hole. A plurality of groups of backing plates are detachably and fixedly provided on the hollow rotating column. The medicine bottle conveying disk is rotatably connected between the backing plates of the same group along the central axis of the hollow rotating column. An arc-shaped positioning slot for accommodating the positioning column is provided on the backing plate. At the same time, a control assembly for controlling the independent rotation of the medicine bottle conveying disk is provided in the hollow rotating column.

[0010] The present invention is further configured such that: the control assembly includes an elastic pin assembly fixedly provided on the hollow rotating column for engaging with the pin slot to enable the hollow rotating column to drive the corresponding medicine bottle conveying disk to rotate. The elastic pin assembly includes a pin slidably connected to the side wall of the hollow rotating column. The pin is connected to the hollow rotating column based on a spring. An abutting assembly for abutting against the pin to drive the pin to protrude and extend into the pin slot is fixedly provided on the driving motor.

[0011] The present invention is further configured that: the abutting component includes a control lead screw coaxially and rotatably connected inside the hollow rotating column, a sliding block that is connected in cooperation with the control lead screw and is slidably connected inside the hollow rotating column and is used to abut the latch, a control motor for driving the control lead screw to rotate is fixedly arranged on the driving motor, the abutting block is spherical, and the part of the latch located inside the hollow rotating column is also spherical.

[0012] The present invention is further configured that: the medicine bottle packing device includes a plurality of medicine bottle conveying belts arranged along the vertical direction and corresponding to the medicine bottle conveying trays one by one. The starting end of the conveying belt is externally connected to a bottle tray conveying line for conveying medicine bottle trays. A rectifying component is fixedly arranged on the medicine bottle conveying belt, and the end of the medicine bottle conveying belt is fixedly provided with a medicine box expanding rod for positioning the four right-angled sides of the medicine box to open the medicine box.

[0013] The second object of the present invention is to provide a packaging method for cefamandole nafate for injection medicine bottles, and its advantage is that it can meet the production requirements of different specifications of cefamandole nafate for injection, reduce the cost of setting up the production line, and reduce the floor area.

[0014] The above technical object of the present invention is achieved through the following technical solutions: A packaging method for cefamandole nafate for injection medicine bottles, which applies an automatic packaging device for cefamandole nafate for injection medicine bottles as described in any of the above technical solutions, includes:

[0015] Step 1: The medicine bottle filling device automatically fills the cefamandole nafate for injection powder into the vial and seals it. A number of preliminarily packaged medicine bottles of different specifications are output from the output production line and then converge into the medicine bottle confluence production line for mixing;

[0016] Step 2: The medicine bottles of different specifications enter the medicine bottle screening line for screening. At the output end of the medicine bottle screening line at the same height, the large medicine bottles are hung on the medicine bottle sorting components arranged on the medicine bottle conveying trays, and the small medicine bottles cannot be hung on the corresponding medicine bottle sorting components and continue to move downward along the medicine bottle screening line until they are hung on the corresponding medicine bottle sorting components;

[0017] Step 3: When the medicine bottle sorting components on a certain medicine bottle conveying tray are filled with medicine bottles, the driving component drives the corresponding medicine bottle conveying tray to rotate by a certain angle to convey the filled medicine bottle sorting components to the medicine bottle packing device for packing. At the same time, the medicine bottle conveying tray will rotate the empty medicine bottle sorting components along the rotation direction to the output end of the medicine bottle screening line for subsequent medicine bottle sorting;

[0018] Step 4: The medicine bottles conveyed to the medicine bottle packing device are rectified and then packed.

[0019] In summary, the present invention has the following beneficial effects:

[0020] 1. A medicine bottle rotary conveying device is provided, which consists of several medicine bottle conveying disks arranged coaxially along the vertical direction. A number of medicine bottle sorting components are evenly arranged on the medicine bottle conveying disks and inclined downward along the vertical direction. A driving component is provided to drive the medicine bottle conveying disks to rotate independently. When the mixed medicine bottles pass through the first medicine bottle screening line, the largest-sized medicine bottles cannot pass through the spacing between the abutting plates of the medicine bottle sorting component arranged at the top, so that the concave grooves on the medicine bottles can be clamped between the two abutting plates, while the smaller-sized medicine bottles can smoothly pass between the two abutting plates and enter the next medicine bottle screening line and repeat this step. When the pressure sensor in the topmost medicine bottle sorting component senses that the number of medicine bottles on the medicine bottle sorting component is sufficient, the driving component drives the topmost medicine bottle conveying disk to rotate by a certain angle and conveys it to the medicine bottle packing device for packing the medicine bottles. At the same time, the other medicine bottle conveying disks at the bottom will not rotate. Thus, when producing cefamandole nafate for injection of different specifications, only the medicine bottle filling device arranged at the front needs to be set separately. The produced medicine bottles directly enter the medicine bottle confluence assembly line for mixing, pass through the medicine bottle screening line for screening, and then are conveyed to the corresponding medicine bottle packing device for packing through the medicine bottle rotary conveying device. This reduces the cost of setting up the production line, reduces the floor area, and at the same time enables the enterprise to adapt to the production requirements of cefamandole nafate for injection of different specifications. And when changing the production specification of cefamandole nafate for injection, it is also more convenient to modify, and the modification cost is lower;

[0021] 2. By setting several groups of pads for placing the medicine bottle conveying disks on the hollow rotating column, and respectively setting arc-shaped positioning grooves and positioning columns on the pads and on the medicine bottle conveying disks, while ensuring the rotational concentricity between the medicine bottle conveying disk and the hollow rotating column, it also ensures that they can move automatically. At the same time, a detent is set on the hollow rotating column based on a spring, and a contact block is arranged in the hollow rotating column that can slide along the vertical direction to abut against the detent protruding from the side wall of the hollow rotating column. When the pressure sensor in the medicine bottle sorting component senses that the number of medicine bottles on the medicine bottle sorting component is sufficient, first, the contact block moves to the height of the corresponding medicine bottle conveying disk to abut against the detent protruding from the hollow rotating column and extends into the detent groove in the medicine bottle rotating disk. At this time, the medicine bottle conveying disk and the hollow rotating column are relatively fixed. When the driving motor drives the hollow rotating column to rotate, it will also drive this medicine bottle conveying disk to rotate, so as to move the filled medicine bottle sorting component to the medicine bottle packing device for packing, and at the same time move the empty medicine bottle sorting component to the corresponding medicine bottle screening line for screening of the medicine bottles. With a simple structure and a low-cost structure, the independent rotation of multiple medicine bottle conveying disks is realized. Description of the Drawings

[0030] The present invention will be further described in detail below with reference to the accompanying drawings.

[0031] Embodiment 1:

[0032] Refer to Figures 1 to 3, An automatic packaging device for cefamandole nafate injection vials, including a vial filling device 1 for automatically filling cefamandole nafate injection powder into vials and sealing them. Along the conveying direction of the vials, the vial filling device 1 includes a vial conveying line, a cefamandole nafate injection powder filling device, a rubber stopper installer, and an aluminum-plastic cover installer. The vial conveying line is used to convey vials of different specifications and sizes. The cefamandole nafate injection powder filling device is used to fill a set weight of cefamandole nafate injection powder into the vials. The rubber stopper installer is used to automatically install rubber stoppers on the vials. The aluminum-plastic cover installer is used to install an aluminum-plastic cover at the mouth of the vial to fix the rubber stopper. At the same time, an output conveyor line 11 for outputting the vials already filled with cefamandole nafate injection powder is also provided at the outlet of the vial filling device 1. A number of groups of vial filling devices 1 are arranged in parallel to produce cefamandole nafate injection of different specifications. The output conveyor lines 11 of several groups of vial filling devices 1 converge at the vial confluence conveyor line 2 to mix vials of different specifications. At the end of the vial confluence conveyor line 2 far from the vial filling device 1, there are several sets arranged in a stepped manner along the vertical direction, and a vial screening line 3 for screening out vials in the order from largest to smallest. At the same time, at the output end of the vial screening line 3, there is a vial packing device 5 for packing the vials and a vial rotary conveying device 4 for conveying the packed vials to the vial packing device 5 for packing in a certain quantity. The width of the vial confluence conveyor line 2 gradually decreases along the conveying direction of the vials until it decreases to be equal to the diameter of the largest specification vial. The width of the vial screening line 3 gradually decreases from top to bottom to be equal to the diameter of the smallest specification vial. In this embodiment, the vials are divided into 3 grades, from largest to smallest are large vials, medium vials, and small vials. The vials are divided into a vial body, a vial neck, and a vial cap. The vial neck is designed with an inner concave. The diameters of the vial body and the vial cap are close. The diameter of the vial neck of a high-specification vial is larger than the diameter of the vial body of a smaller specification. At the same time, there are also 3 sets of vial screening lines 3 arranged along the vertical direction, which are used in sequence to screen out large vials, medium vials, and small vials respectively.

[0033] Reference Figure 4 and Figure 6, Specifically, the medicine bottle rotary conveying device 4 is rotationally connected with a plurality of medicine bottle conveying discs 41 along the vertical direction coaxially. The medicine bottle conveying discs 41 are evenly provided with a plurality of medicine bottle sorting components 42 along the circumferential direction for separating medicine bottles of corresponding specifications from the corresponding medicine bottle screening line 3. One of the medicine bottle sorting components 42 is arranged at the output end of the medicine bottle screening line 3, and a driving component 43 capable of driving the plurality of medicine bottle conveying discs 41 to rotate independently is also provided. In this embodiment, there are 3 groups of medicine bottle conveying discs 41 arranged along the vertical direction, and 2 medicine bottle sorting components 42 are symmetrically arranged on each medicine bottle conveying disc 41. The connecting line of the two medicine bottle sorting components 42 passes through the center point of the medicine bottle conveying disc 41. However, it is not limited to only being able to set two medicine bottle sorting components 42. The number of medicine bottle sorting components 42 can be increased to improve the screening and packing efficiency. Similarly, when more specifications of cefamandole nafate for injection need to be produced, the number of medicine bottle conveying discs 41 can also be increased.

[0034] Reference Figure 1 and Figure 3 , Specifically, the medicine bottle sorting component 42 includes a group of sorting plates 421 rotationally connected coaxially on the medicine bottle conveying disc 41 and a sorting motor 422 for driving a group of sorting plates 421 to rotate in opposite directions towards each other. The sorting plate 421 includes a rotating part 423 rotationally connected to the medicine bottle conveying disc 41 and a contact plate 424 fixedly connected to the rotating part 423 for abutting against the concave groove on the vial. When the sorting motor 422 drives the contact plates 424 to rotate to a parallel position, the distance between the contact plates 424 is equal to the diameter of the concave groove of the vial of the corresponding specification, that is, the diameter of the bottleneck, and is simultaneously larger than the maximum diameter of the bottle body of smaller-sized medicine bottles. At the same time, a pressure sensor 425 for sensing the total weight of the medicine bottles on the sorting plate 421 is fixedly provided at one end of the contact plate 424 close to the rotating part 423. To prevent the medicine bottles from falling off the sorting plate 421 during the rotation of the medicine bottle conveying disc 41, the sorting plate 421 is arranged obliquely downward along the conveying direction of the medicine bottle screening line 3, so that the medicine bottles are placed in a slightly inclined direction. Similarly, a recoverable bayonet can be provided at the end of the sorting plate 421 far from the rotation center, so that the medicine bottles can freely enter but cannot slide out. Only when the sorting plate 421 opens can the medicine bottles break away from between the sorting plates 421. When the pressure sensor 425 in the medicine bottle sorting component 42 senses that the number of medicine bottles on the medicine bottle sorting component 42 is sufficient, the driving component 43 drives the corresponding medicine bottle conveying disc 41 to rotate by a certain angle and transports it to the medicine bottle packing device 5 for packing the medicine bottles. At the same time, the sorting plate 421 has a certain magnetism and can adsorb on the medicine bottle screening line 3. Only when the driving force for driving the medicine bottle conveying disc 41 reaches the standard can the driving of the medicine bottle conveying disc 41 for rotation be realized.

[0035] Reference Figures 4 to 7, Specifically, the medicine bottle conveying disk 41 gradually decreases in diameter from top to bottom along the vertical direction. A rotating hole 411 is provided at the central position of the medicine bottle conveying disk 41. At the same time, a pin slot 412 is provided in the rotating hole 411. The number of pin slots 412 corresponds one-to-one with the medicine bottle sorting assembly 42. At the same time, a number of positioning posts 413 are evenly fixed around the rotating hole 411 at both ends of the medicine bottle conveying disk 41. Specifically, the driving assembly 43 includes a fixedly arranged driving motor 431. A hollow rotating column 432 arranged along the vertical direction is coaxially fixed on the rotating shaft of the driving motor 431. The diameter of the hollow rotating column 432 is smaller than the diameter of the rotating hole 411. At the same time, a number of groups of backing plates 433 are detachably fixed on the hollow rotating column 432. The medicine bottle conveying disk 41 is rotatably connected between the backing plates 433 of the same group along the central axis of the hollow rotating column 432. An arc-shaped positioning slot 434 for accommodating the positioning post 413 is provided on the backing plate 433. By providing a number of groups of backing plates 433 for placing the medicine bottle conveying disk 41 on the hollow rotating column 432, and respectively providing an arc-shaped positioning slot 434 and a positioning post 413 on the backing plate 433 and the medicine bottle conveying disk 41, the arc-shaped positioning slot 434 coincides with the axis of the medicine bottle conveying disk 41. The positioning post 413 can slide along the circumferential direction in the arc-shaped positioning slot 434. At the same time, in order to ensure that there are always two positioning posts 413 in the arc-shaped positioning slot 434 to ensure the rotational concentricity between the bottle conveying disk 41 and the hollow rotating column 432, the positioning post 413 is provided with no less than 3 and the sum of the central angles of the arc-shaped positioning slot 434 is not less than 270 degrees, so as to ensure the rotational concentricity between the medicine bottle conveying disk 41 and the hollow rotating column 432 while ensuring that they can move automatically. That is, under normal circumstances, when the driving motor 431 drives the hollow rotating column 432 to rotate, the medicine bottle conveying disk 41 arranged on the hollow rotating column 432 is in a separated state, resulting in the hollow rotating column 432 being unable to drive the medicine bottle conveying disk 41 to rotate. At the same time, a control assembly 436 for controlling the independent rotation of the medicine bottle conveying disk 41 is provided in the hollow rotating column 432.

[0036] Reference Figures 4 to 7 , Specifically, the control assembly 436 includes an elastic pin assembly 437 fixedly arranged on the hollow rotating column 432 for clamping the pin slot 412 to realize the rotation of the corresponding medicine bottle conveying disk 41 driven by the hollow rotating column 432. The elastic pin assembly 437 includes a pin 4371 slidably connected to the side wall of the hollow rotating column 432. The pin 4371 is connected to the hollow rotating column 432 based on a spring 4372. An abutting assembly 438 for abutting against the pin 4371 to drive the pin 4371 to protrude into the pin slot 412 is fixedly arranged on the driving motor 431.

[0037] Reference Figures 4 to 7, specifically, the abutting component 438 includes a control lead screw 4381 coaxially and rotatably connected inside the hollow rotating column 432. A sliding connection block 4382 that is slidably connected inside the hollow rotating column 432 and used to abut against the latch pin 4371 is fitted and connected to the control lead screw 4381. A control motor 4383 for driving the rotation of the control lead screw 4381 is fixedly provided on the driving motor 431. The abutting block 4382 is spherical in shape, and the part of the latch pin 4371 located inside the hollow rotating column 432 is also spherical in shape. When the pressure sensor 425 in the medicine bottle sorting component 42 senses that the number of medicine bottles on the medicine bottle sorting component 42 is sufficient, first, the abutting block 4382 moves to the height of the corresponding medicine bottle conveying tray 41 to abut against the latch pin 4371 provided there, protruding from the hollow rotating column 432 and thus extending into the latch slot 412 in the medicine bottle rotating tray. At this time, the relative position between the medicine bottle conveying tray 41 and the hollow rotating column 432 is fixed. When the driving motor 431 drives the rotation of the hollow rotating column 432, it will also drive the rotation of this medicine bottle conveying tray 41, so as to move the filled medicine bottle sorting component 42 to the medicine bottle packing device 5 for packing, and at the same time move the empty medicine bottle sorting component 42 to the corresponding medicine bottle screening line 3 for screening medicine bottles.

[0038] Reference Figure 1 and Figure 7 , specifically, the medicine bottle packing device 5 includes a number of medicine bottle conveying belts 51 arranged along the vertical direction and corresponding to the medicine bottle conveying trays 41 one by one. At the starting end of the medicine bottle conveying belt 51, a bottle holder conveying line for conveying the medicine bottle holder is externally connected. At the same time, a rectifying component 52 is fixedly provided on the medicine bottle conveying belt 51. At the end of the medicine bottle conveying belt 51, a medicine box expansion rod 53 for positioning the four right-angle sides of the medicine box to realize the opening of the medicine box is fixedly provided. When performing medicine bottle packaging, first, the medicine box is opened and placed on the medicine box expansion rod 53. When the medicine bottle holder enters the medicine bottle conveying belt 51 from the medicine bottle conveying line, the rectifying component 52 performs rectification. Subsequently, the medicine bottle rotating and conveying device 4 conveys a number of medicine bottles to directly above the medicine bottle holder. Subsequently, the sorting motor 422 rotates to drive the two sorting blocks to open, and the medicine bottles enter the medicine bottle holder and are then conveyed into the medicine box, and the worker performs manual packing.

A number of preliminarily packaged medicine bottles of different specifications are output from the output assembly line 11 and then converge into the medicine bottle converging assembly line 2 for mixing;

[0042] Step 2: Vials of different specifications enter the vial screening line 3 for screening. At the output end of the vial screening line 3 at the same height, the large vials are mounted on the vial sorting component 42 provided on the vial conveying tray 41, and the small vials cannot be mounted on the corresponding vial sorting component 42 and continue to move downward along the vial screening line 3 until they are mounted on the corresponding vial sorting component 42;

[0043] Step 3: When the vial sorting component 42 on a certain vial conveying tray 41 is filled with vials, the driving component 43 drives the corresponding vial conveying tray 41 to rotate by a certain angle to convey the filled vial sorting component 42 to the vial packing device 5 for packing. At the same time, the vial conveying tray 41 will rotate the empty vial sorting component 42 to the output end of the vial screening line 3 along the

[0044] rotation direction for subsequent vial sorting;

[0045] Step 4: The vials conveyed to the vial packing device 5 are rectified and then packed;

[0046] Step 4.1: The worker opens the medicine box and places it on the medicine box expansion rod 53;

[0047] Step 4.2: After the vial holder enters the vial conveying belt 51 from the vial conveying line, the rectifying component 52 rectifies the vial holder;

[0048] Step 4.3: The vial rotary conveying device 4 conveys a certain number of vials of a certain specification above the vial holder. The sorting motor 422 rotates to drive the two sorting blocks to open, and the vials enter the vial holder;

[0049] Step 4.4: The vial conveying belt 51 conveys the vial holder and several vials into the medicine box together, and the worker performs manual packing.

[0050] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. Those skilled in the art can make creative contributions to this embodiment according to their needs after reading this specification, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
