[0002] During the drug production process, a clean environment of the corresponding level must be maintained to prevent drug contamination.

[0003] The sources of drug contamination include foreign matter brought by packaging materials. Foreign matter brought by packaging materials is determined by the production characteristics of packaging materials: packaging materials are mainly produced by injection blowing or extrusion blowing, and this production process inevitably brings foreign matter such as burrs, burrs and debris. Once mixed into the drugs, it affects the safety of patients' medication and also brings huge economic losses to pharmaceutical companies. Therefore, how to avoid foreign matter brought by packaging materials is very critical.

[0044] Furthermore, the filling equipment may also include an assembly component, which is connected to the feeding device and is used to assemble the bottles, stoppers or caps output by the feeding device into finished pharmaceutical products.

[0045] like Figure 1-Figure 3 As shown, the feeding device includes a material sorting component 200, a material discharging track 300 and an air suction device 100. The material sorting component 200 includes a material sorting hopper 201 and a material sorting track 202. The material sorting hopper 201 is provided with the material sorting track 202. The material sorting hopper 201 can hold packaging materials 400 and sort the packaging materials 400 into the material sorting track 202. The material discharging track 300 is connected to the material sorting track 202. The air suction device 100 includes an air suction hood 1, a mounting component 2 and a vacuum pump 3. The air suction hood 1 can The mounting assembly 2 includes a first mounting seat 21 and a second mounting seat 22, which are arranged perpendicular to the discharging direction of the packaging material 400. The first mounting seat 21 and the second mounting seat 22 are installed on opposite sides of the discharging track 300. The first mounting seat 21 and the second mounting seat 22 are both connected to the suction hood 1, and an suction compartment is formed inside for the packaging material 400 and the discharging track 300 to pass through, so as to improve the suction efficiency. The vacuum pump 3 is connected to the suction hood 1. The packaging material 400 is sorted in the sorting hopper 201 to the sorting track 202, and transported to the discharging track 300. The suction device 100 sucks the packaging material 400 in the discharging track 300 to suck away the foreign matter on the surface of the packaging material 400, and avoids the foreign matter from being mixed into the material to be filled, so as to ensure the safety of the patient's medication and the filling quality. The setting of the suction device 100 has a simple structure and is easy to install. There is no need to increase the cleanliness requirements of the purchased packaging materials 400, nor is there any need for pharmaceutical companies to purchase processing equipment to clean, dry, sterilize and other processes for the packaging materials 400. There is no need to carry out major modifications to the factory buildings and production lines. The investment cost is relatively low and the production time of the drugs will not be excessively extended.

[0046] like Figure 1 and Figure 2 As shown, the discharge track 300 includes at least two track forming members 301 , each track forming member 301 is installed outside the sorting hopper 201 , and each track forming member 301 is arranged at intervals along the circumference of the packaging material 400 to form a discharge track 300 for accommodating and transporting the packaging material 400 .

[0047] Furthermore, the extension direction of the track forming member 301 is determined by the extension direction of the discharge track 300 and can be set according to actual conditions, which is not limited in this embodiment.

[0048] In this embodiment, there are four track forming members 301, and the track forming members 301 are in a strip shape. Exemplarily, the four track forming members 301 surround a discharge track 300 with a substantially circular cross section.

[0049] Furthermore, the feeding device further comprises a fixing seat 302 , which is installed outside the material sorting hopper 201 , and each track forming member 301 is fixed outside the material sorting hopper 201 through the fixing seat 302 .

[0050] Furthermore, a fixing hole 303 is formed on the fixing seat 302 , and the track forming members 301 are all installed in the fixing hole 303 .

[0051] In this embodiment, the shape of the fixing hole 303 is not limited, and can be square, circular, etc., and can be set according to the specific number and layout of the track forming members 301, as long as it is convenient to fix each track forming member 301.

[0052] Furthermore, in order to increase the stability of the track forming member 301 , at least one fixing seat 302 may be arranged at intervals in the extension direction of the discharge track 300 , and each fixing seat 302 can fix each track forming member 301 .

[0053] like Figure 1 As shown, the suction device 100 further includes a collecting bag 4 , which is connected to the vacuum pump 3 , and is used to collect foreign matter sucked from the packaging material 400 .

[0054] Furthermore, the suction device 100 also includes a first suction pipe 5 , one end of which is connected to the suction hood 1 , and the other end of which is connected to the collection bag 4 , and the vacuum pump 3 is in communication with the first suction pipe 5 .

[0055] Furthermore, the suction device 100 further includes a second suction pipe 6, one end of which is connected to the vacuum pump 3, and the other end of which is connected to the first suction pipe 5. Under the action of the vacuum pump 3, a negative pressure state is formed in the first suction pipe 5, so as to suck out foreign matter on the packaging material 400, and most of the foreign matter will enter the collection bag 4, and may also be deposited in the first suction pipe 5. In order to improve the suction effect, the foreign matter deposited in the first suction pipe 5 can be cleaned into the collection bag 4 regularly.

[0056] Specifically, the collecting bag 4 is detachably connected to the first suction pipe 5 to facilitate replacement of the collecting bag 4 .

[0057] Furthermore, the suction device 100 further includes a one-way valve, which is disposed between the collection bag 4 and the vacuum pump 3, so that the foreign matter sucked from the packaging material 400 can enter the collection bag 4 in one direction under the action of the vacuum pump 3. The provision of the one-way valve can prevent the foreign matter from flying or flowing back. Specifically, the one-way valve can be installed in the first suction pipe 5, and is located at a section from the connection port of the collection bag 4 and the vacuum pump 3 to the collection bag 4.

[0058] like Figure 2 As shown, the mounting assembly 2 further includes a connecting column 23 , and the first mounting seat 21 and the second mounting seat 22 are connected via the connecting column 23 , and the connecting column 23 is detachably connected to the discharge track 300 .

[0059] Specifically, the connecting column 23 can be a stainless steel bolt, which is bound to the discharge track 300 through a nut, or can be directly overlapped on the discharge track 300, and can be set specifically according to actual installation requirements and installation angles.

[0060] Furthermore, the number of the connecting pillars 23 is at least one, and the connecting pillars 23 are arranged in parallel to increase the connection strength.

[0061] In this embodiment, the number of the connecting pillars 23 is two.

[0062] Furthermore, the mounting assembly 2 further includes a fastener 24 , and the connecting column 23 and the first mounting seat 21 are connected via the fastener 24 , and the connecting column 23 and the second mounting seat 22 are also connected via the fastener 24 .

[0063] like Figure 3 As shown, the feeding device further includes a feeding assembly 500, which includes a feeding hopper 501 and a feeding track 502. The feeding port of the feeding hopper 501 is connected to the feeding track 502, and the feeding track 502 is connected to the material sorting hopper 201. The packaging material 400 first enters the feeding hopper 501, and then enters the material sorting hopper 201 through the feeding track 502.

[0064] Furthermore, the middle area of ​​the bottom of the material hopper 201 protrudes toward the top of the material hopper 201, and the material track 202 is arranged on the side wall of the material hopper 201 in a spiral upward shape. After the packaging material 400 enters the material hopper 201 from the unloading assembly 500, the packaging material 400 rolls onto the circumference of the material hopper 201 due to the middle area of ​​the bottom of the material hopper 201 protruding toward the top of the material hopper 201, and with the help of external force such as a peristaltic pump, the packaging material 400 is made to enter the material track 202. In this process, the packaging material 400 is neatly arranged on the material track 202, and is transported upward in a spiral, and then transported to the discharge track 300.

[0065] The present embodiment does not limit the specific structure of the material sorting component 200 , as long as it can play the role of sorting materials so that the packaging materials 400 are arranged in sequence along the conveying direction.

[0066] Furthermore, the suction direction of the suction hood 1 is not perpendicular to the discharge direction of the packaging material 400. Such a setting promotes the suction of foreign matter on the inner surface, so that the suction hood 1 can not only suck foreign matter on the surface of the packaging material 400, but also suck foreign matter inside the packaging material 400, thereby improving the effect of the suction device 100 in sucking foreign matter.

[0067] Furthermore, the suction direction of the suction hood 1 can promote the discharge of the packaging material 400, so that the suction airflow can promote the discharge of the packaging material 400, which can prevent the packaging materials 400 arranged in sequence from being blocked during the adsorption process, and then the foreign matter inside the packaging material 400 is also sucked away, thereby improving the effect of the suction device 100 in sucking out foreign matter.

[0068] The suction direction of the suction hood 1 can promote the discharge of the packaging material 400, which means that the component of the suction direction of the suction hood 1 in the discharge direction of the packaging material 400 is in the same direction as the discharge direction of the packaging material 400, thereby achieving the effect of promoting the discharge of the packaging material 400.

[0069] In order to make the suction device 100 more effective in sucking out foreign matter, at least one group of suction devices 100 may be arranged on the discharge track 300. The suction direction of each group of suction devices 100 may have different angles with the discharge direction of the packaging material 400, so as to suck out the packaging material 400 from multiple angles, thereby sucking away more foreign matter.

[0070] In addition, since the packaging materials 400 are arranged in sequence in the discharge track 300, but the arrangement of the packaging materials 400 is not necessarily connected end to end, that is, for example, when the packaging materials 400 are bottles, the adjacent bottles may have their mouths facing each other, or their mouths facing each other, and multiple groups of suction devices 100 can also be set up to suck out foreign matter inside the packaging materials 400, wherein the suction direction of several groups of suction devices 100 can also be along the direction that hinders the discharge of the packaging materials 400, so that foreign matter inside the bottles in different directions can also be sucked out, so that the suction device 100 has a better effect of sucking out foreign matter. Of course, the suction force of the multiple groups of suction devices 100 is still along the direction that promotes the discharge of the packaging materials 400 to ensure that the packaging materials 400 are discharged smoothly.

[0071] Furthermore, the vacuum pumps 3 in each group of suction devices 100 can be shared or individually provided, and the collecting bags 4 corresponding to the vacuum pumps 3 can also be shared or individually provided, which can be set according to actual conditions.

[0072] This embodiment does not limit the angle between the suction direction of each group of suction devices 100 and the discharge direction of the packaging material 400, and can be set according to actual conditions.

[0073] like Figure 4 and Figure 5 As shown, two implementation modes are shown in which the suction direction of the suction hood 1 is non-vertically arranged to the discharge direction of the packaging material 400. Figure 4 When the discharge track 300 is arranged to be tilted downward, the suction direction of the suction hood 1 is finally converted into the vertical downward direction of the first suction pipe 5; Figure 5 When the discharge track 300 is arranged horizontally, the suction direction of the suction hood 1 is finally converted into a direction in which the first suction pipe 5 is inclined toward the downward feeding direction. Both of the above methods are for achieving a better effect of sucking out foreign matter.

[0074] The working process of the filling equipment provided in this embodiment is as follows:

[0075] The packaging material 400 first enters the discharge hopper 501 and then enters the sorting hopper 201 via the discharge track 502;

[0076] Since the middle area of ​​the bottom of the material hopper 201 protrudes toward the top of the material hopper 201, the packaging materials 400 roll onto the circumference of the material hopper 201 under the action of external force (such as a peristaltic pump) and enter the material hopper track 202. In this process, the packaging materials 400 are neatly arranged on the material hopper track 202, and are transported upward in a spiral, and then transported to the discharge track 300;

[0077] During the transportation in the discharge track 300, the suction hood 1 suctions the packaging material 400 under the action of the vacuum pump 3, so as to suck the foreign matter on the surface of the packaging material 400 into the collection bag 4. The suctioned packaging material 400 continues to be transported from the discharge track 300 to the next process, such as filling through the filling component and assembling into the final product through the assembly component.

[0078] Although the utility model has been described in detail above by means of general description, specific implementation methods and tests, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model. Therefore, these modifications or improvements made without departing from the spirit of the utility model are within the scope of protection claimed by the utility model.
