Description

Technical Field

[0001] The utility model relates to food and medicine packaging equipment, in particular to a filling machine. Background Art

[0002] In the fields of pharmaceutical manufacturing and cell diagnosis, cryotubes and screw-neck vials are both commonly used packaging materials. Usually, for different types of packaging materials, pharmaceutical factories need to use two different filling and capping machines for production (for vials and other conventional bottles, they are generally transported to the filling device without caps, or in an open state before filling, and then capped and screwed after filling; while cryotubes come with caps, so the caps need to be opened before filling and tightened again after filling, resulting in the non-universality of filling machines for these two types of packaging materials). For pharmaceutical factories that want to produce products with both types of packaging materials, they have to purchase two filling and capping machines, which will increase the costs of the factories and the floor area required. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a filling machine with a simple structure, a wide application range, which is conducive to cost savings and reduction of the floor area occupied.

[0004] To solve the above technical problem, the utility model adopts the following technical solutions:

[0005] A filling machine includes a first bottle feeding mechanism, a second bottle feeding mechanism, a transition mechanism, a bottle conveying mechanism, a first capping mechanism, a filling mechanism, a cap adding mechanism and a second capping mechanism. The transition mechanism is arranged at the bottle feeding end of the bottle conveying mechanism. Both the first bottle feeding mechanism and the second bottle feeding mechanism are docked with the transition mechanism. The bottle conveying mechanism is provided with a bottle conveying part and a cap conveying part. The first capping mechanism, the filling mechanism, the cap adding mechanism and the second capping mechanism are arranged in sequence along the conveying direction of the bottle conveying mechanism.

[0006] As a further improvement of the above technical solution: The transition mechanism includes a first bottle feeding dial and a second bottle feeding dial arranged between the first bottle feeding dial and the bottle conveying mechanism. The first bottle feeding mechanism is docked with the first bottle feeding dial, and the second bottle feeding mechanism is docked with the second bottle feeding dial.

[0007] As a further improvement of the above technical solution: An in-bottle counting sensor is arranged on the side of the second bottle feeding dial.

[0008] As a further improvement of the above technical solution: The first bottle feeding mechanism includes a first bottle arranging component and a first bottle feeding track. The first bottle feeding track is arranged between the first bottle arranging component and the first bottle feeding dial. An in-bottle empty sensor is arranged on the side of the first bottle feeding track.

[0009] As a further improvement of the above technical solution: the second bottle feeding mechanism includes a second bottle arranging component, a second bottle feeding track, and a vibrating component for driving the second bottle feeding track to vibrate, and the second bottle feeding track is arranged between the second bottle arranging component and the second bottle feeding dial.

[0010] As a further improvement of the above technical solution: a pre-filling sampling component and a pre-filling weighing component are provided upstream of the filling mechanism;

[0011] And / or, a post-filling sampling component and a post-filling weighing component are provided downstream of the filling mechanism.

[0012] As a further improvement of the above technical solution: the filling mechanism includes a filling pump and a filling component connected to the filling pump, and the post-filling weighing component is in signal connection with the filling pump.

[0013] As a further improvement of the above technical solution: a cap arranging component is provided on the side of the capping mechanism.

[0016] Compared with the prior art, the advantages of the present utility model are as follows: for the filling machine disclosed by the present utility model, different types of bottle bodies can be selected to enter the bottle through the first bottle feeding mechanism or the second bottle feeding mechanism, and finally enter the bottle conveying mechanism with the help of the transition mechanism. For the bottle bodies that need to be capped before filling, the first capping mechanism can first open the bottle cap and place it on the cap conveying part of the bottle conveying mechanism to make the bottle cap and the bottle body be transmitted synchronously. After the bottle body is filled, the second capping mechanism can re-tighten the bottle cap. For the bottle bodies that do not need to be capped before filling, the first capping mechanism does not need to act. After filling is completed, the capping mechanism feeds the bottle cap onto the bottle body, and then the second capping mechanism tightens the bottle cap. The overall structure is simple, and it can be applicable to different types of bottle bodies, thereby saving the equipment cost of the pharmaceutical factory and reducing the occupied area of the workshop.

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] Figures 1 to 2 An embodiment of the utility model is shown. The filling machine of this embodiment includes a first bottle feeding mechanism 1, a second bottle feeding mechanism 2, a transition mechanism 3, a bottle conveying mechanism 4, a first capping mechanism 5, a filling mechanism 6, a capping mechanism 7 and a second capping mechanism 8. The transition mechanism 3 is arranged at the bottle feeding end of the bottle conveying mechanism 4. The first bottle feeding mechanism 1 and the second bottle feeding mechanism 2 are both connected to the transition mechanism 3. The bottle conveying mechanism 4 is provided with a bottle conveying part 41 and a capping part 42. The first capping mechanism 5, the filling mechanism 6, the capping mechanism 7 and the second capping mechanism 8 are arranged in sequence along the conveying direction of the bottle conveying mechanism 4. For details, see Figure 2 The bottle conveying part 41 preferably adopts a clamping groove, which conveys the bottle by clamping the neck of the bottle body, has good reliability, and is convenient for connecting the bottle body with the second bottle feeding dial wheel 32 and the waste rejection dial wheel 91; the cap conveying part 42 preferably adopts a groove to facilitate the positioning of the bottle cap. Of course, in other embodiments, other forms can also be used.

[0027] In the filling machine of this embodiment, different types of bottles can be selected to enter the first bottle feeding mechanism 1 or the second bottle feeding mechanism 2, and finally enter the bottle conveying mechanism 4 with the help of the transition mechanism 3. For bottles that need to be capped before filling (such as cryopreservation tubes and similar bottles), the bottle cap can be opened by the first capping mechanism 5 and placed on the capping part 42 of the bottle conveying mechanism 4, so that the bottle cap and the bottle are transmitted synchronously. After the bottle is filled, the bottle cap is tightened again by the second capping mechanism 8; for bottles that do not need to be capped before filling (such as cillin bottles and similar bottles), the first capping mechanism 5 does not need to be operated. After the filling is completed, the capping mechanism 7 loads the bottle cap onto the bottle, and then the bottle cap is tightened by the second capping mechanism 8. The filling machine of this embodiment has a simple overall structure and can be applied to different types of bottles, thereby saving the equipment cost of the pharmaceutical factory and reducing the occupied plant area.

[0028] Furthermore, in this embodiment, the transition mechanism 3 includes a first bottle inlet dial 31 and a second bottle inlet dial 32 disposed between the first bottle inlet dial 31 and the bottle conveying mechanism 4. The first bottle inlet mechanism 1 is docked with the first bottle inlet dial 31, and the second bottle inlet mechanism 2 is docked with the second bottle inlet dial 32. During operation, the bottles of the first bottle inlet mechanism 1 can be fed into the bottle conveying mechanism 4 through the first bottle inlet dial 31 and the second bottle inlet dial 32 in sequence, and the bottles of the second bottle inlet mechanism 2 can be fed into the bottle conveying mechanism 4 through the second bottle inlet dial 32. The structure is compact, occupying less space, and the first bottle inlet mechanism 1 and the second bottle inlet mechanism 2 do not affect each other. Of course, in other embodiments, the transition mechanism 3 can also be in other forms. For example, a bottle conveying mesh belt combined with a bottle conveying auger can replace the first bottle inlet dial 31; or the first bottle inlet dial 31 and the second bottle inlet dial 32 are respectively docked with different bottle conveying parts 41 on the bottle conveying mechanism 4, etc.

[0029] Furthermore, in this embodiment, a bottle inlet counting sensor 33 is provided on the side of the second bottle inlet dial 32. The bottle inlet counting sensor 33 can be used to count the number of bottles entering the bottle conveying mechanism 4 from the first bottle inlet mechanism 1 or the second bottle inlet mechanism 2.

[0030] Furthermore, in this embodiment, the first bottle inlet mechanism 1 includes a first bottle arranging component 11 (which can be, for example, a bottle arranging tray) and a first bottle inlet track 12. The first bottle inlet track 12 is disposed between the first bottle arranging component 11 and the first bottle inlet dial 31, and a bottle inlet empty bottle sensor 13 is provided on the side of the first bottle inlet track 12. During operation, disordered multi-column bottles enter the first bottle arranging component 11 from an upstream device (such as a dryer), are arranged into a single column in the first bottle arranging component 11 and conveyed to the first bottle inlet track 12. The bottle inlet empty bottle sensor 13 is used to detect the minimum cumulative amount of bottle inlet. When the minimum cumulative amount is detected, the device will alarm and stop, reminding the upstream device to feed bottles. It has good reliability and improves the automation and intelligence of the device.

[0031] Furthermore, in this embodiment, the second bottle inlet mechanism 2 includes a second bottle arranging component 21 (which can be, for example, a bottle arranging hopper), a second bottle inlet track 22, and a vibration component 23 for driving the second bottle inlet track 22 to vibrate. The second bottle inlet track 22 is disposed between the second bottle arranging component 21 and the second bottle inlet dial 32. During operation, bagged bottles are added into the second bottle arranging component 21. The second bottle arranging component 21 arranges and outputs the bottles to the second bottle inlet track 22, and drives the vibration through the vibration component 23 to smoothly convey them to the second bottle inlet dial 32. The structure is simple and reliable, and is suitable for cryogenic storage tubes and similar bottles.

[0032] As a preferred embodiment, a pre-filling sampling component 61 and a pre-filling weighing component 62 are provided upstream of the filling mechanism 6. The pre-filling sampling component 61 can first take out the bottle body from the bottle conveying part 41 and transfer it to the pre-filling weighing component 62 for weighing the empty bottle. After weighing, the bottle body is put back into the bottle conveying part 41 for subsequent filling.

[0033] Meanwhile, a post-filling sampling component 63 and a post-filling weighing component 64 are provided downstream of the filling mechanism 6. The post-filling sampling component 63 can take out the bottle body after filling from the bottle conveying part 41 and transfer it to the post-filling weighing component 64 to weigh the total weight. The filling volume can be accurately calculated through the difference between the two weighings before and after. After weighing the filled bottle, the post-filling sampling component 63 puts the bottle body back into the bottle conveying part 41. Of course, in other embodiments, only the empty bottle or the filled bottle can be weighed.

[0034] Further, in this embodiment, the filling mechanism 6 includes a filling pump 65 and a filling component 66 (such as a filling needle, etc.) connected to the filling pump 65. The post-filling weighing component 64 is in signal connection with the filling pump 65. During operation, the filling pump 65 transports the liquid medicine to the filling component 66, and the filling component 66 fills the liquid medicine into the bottle body. If the post-filling weighing component 64 detects that the filling volume of the bottle body is different from the target value, it will feedback a signal to the filling pump 65, and the filling pump 65 adjusts the amount of liquid medicine transported to the filling component 66.

[0035] Further, in this embodiment, a cap arranging component 71 (such as a cap arranging hopper) is provided on the side of the capping mechanism 7. The cap arranging component 71 arranges the bottle caps and outputs them in an orderly manner for the capping mechanism 7 to pick up the caps.

[0036] Further, in this embodiment, a waste rejecting and bottle discharging mechanism 9 is provided at the bottle discharging end of the bottle conveying mechanism 4. The waste rejecting and bottle discharging mechanism 9 includes a waste rejecting dial 91, a bottle discharging dial 92, a waste rejecting channel 93 and a bottle discharging channel 94. The waste rejecting dial 91 is docked with the bottle conveying mechanism 4, the bottle discharging dial 92 and the waste rejecting channel 93 are docked with the waste rejecting dial 91, and the bottle discharging channel 94 is docked with the bottle discharging dial 92. A waste product counting sensor 95 is provided on the side of the waste rejecting channel 93, and a finished product counting sensor 96 is provided on the side of the bottle discharging channel 94. After the bottle body is filled and capped, the qualified products are output in sequence through the waste rejecting dial 91, the bottle discharging dial 92 and the bottle discharging channel 94, and the finished product counting sensor 96 counts the number of qualified products; the unqualified products are output in sequence through the waste rejecting dial 91 and the waste rejecting channel 93, and the waste product counting sensor 95 counts the number of unqualified products to achieve the waste rejecting function.

[0037] As a preferred embodiment, the first capping mechanism 5, the filling mechanism 6 and the second capping mechanism 8 are located on one side of the bottle conveying mechanism 4, and the capping mechanism 7 and the waste removing and bottle discharging mechanism 9 are located on the other side of the bottle conveying mechanism 4. This layout can make full use of the space on both sides of the bottle conveying mechanism 4, and at the same time avoid mutual influence during the operation of each mechanism, with a reasonable layout.
