Description

Technical Field

[0001] The present invention relates to the field of medicine and food packaging, and in particular to an air supply and plugging device and an air supply and plugging method. Background Art

[0002] In the field of pharmaceutical, food, and cosmetic packaging machinery, in order to ensure that the material is filled into the bottle and prolong its shelf life, it is usually filled with inert gas to reduce the oxygen content in the bottle. In this machinery field, there are usually two types of equipment: continuous stoppering and intermittent stoppering. Continuous filling generally adopts the following two inert gas filling (hereinafter referred to as filling) sealing methods:

[0003] Method 1 is a continuous vacuum, nitrogen filling and stoppering method. Its application principle requires that the material bottle be sealed with a mechanical structure first, and then the air in the material bottle is extracted and filled with inert gas, and finally the bottle is stoppered. This device can effectively reduce the residual oxygen content after stoppering to extend the shelf life of the material. However, this method sets the steps of removing the stopper, sealing, vacuuming and nitrogen filling, and stoppering as one workstation, so as to complete the stoppering of the material bottle at one workstation. However, this method will inevitably lead to a long operating cycle of the workstation, and the corresponding time will also increase accordingly, which cannot meet the needs of high-speed filling. In addition, vacuum, nitrogen filling and stoppering require a vacuum system to complete the work. Since the pipeline system formed by the vacuum system also needs to be sterilized, the implementation device is relatively complex and the cost is relatively high.

[0004] Method 2, stoppering under nitrogen protection, involves filling the empty bottle with inert gas before stoppering. A device such as an inflatable plate forms an air curtain to infuse the bottle with inert gas, while also forming a curtain wall at the bottle mouth to prevent air from entering. Finally, stoppering is performed. To increase the filling rate, this method eliminates the need for vacuuming the bottle. Instead, inert gas is injected directly to eliminate the internal gas before stoppering. However, because the bottle and the inflatable plate are in relative motion, a continuous, high-volume gas supply is required to ensure adequate gas entry. Furthermore, gas backflow into the bottle is unavoidable during the idle time between the bottle and the air outlet. This results in a residual oxygen content of 3% to 5% in the bottle after stoppering, failing to meet high-end requirements. Furthermore, existing technologies lack an effective method for supplying gas during the idle time between the stopper and the bottle, which inevitably leads to gas backflow into the bottle during this period.

[0005] Therefore, a plugging device and a method of using the same are needed to solve the above problems. Summary of the Invention

[0006] The purpose of the present invention is to provide a gas supply and plugging device and a gas supply and plugging method to reduce the use of nitrogen and reduce the residual oxygen content inside the material bottle after plugging, and to combine plugging with continuous gas supply to effectively improve the plugging rate of the material bottle.

[0007] In order to solve the above technical problems, the present invention provides an air supply and plugging device, comprising a base plate, a plugging arrangement mechanism, an air supply mechanism, a plugging air blowing mechanism, and a lifting and rotating bottle supporting mechanism;

[0008] The plug sorting mechanism is arranged on one side of the substrate;

[0009] The gas supply mechanism is arranged on the substrate;

[0010] The plug supply and blowing mechanism is arranged on the base plate and can rotate relative to the air supply mechanism, and has vertical blowing holes and inclined blowing holes;

[0011] When the plug supply and blowing mechanism rotates, the air outlet end of the air supply mechanism selectively communicates with the vertical blowing hole or the inclined blowing hole;

[0012] The vertical air blowing hole is also provided with a receiving groove for extracting the bottle stoppers on the stopper sorting mechanism;

[0013] The lifting and rotating bottle supporting mechanism is arranged on the base plate and can rotate synchronously with the plug supply and blowing mechanism. During the rotation process, the bottle body on the lifting and rotating bottle supporting mechanism can rise or fall.

[0014] The air supply mechanism includes an intermediate sleeve and an air chamber cavity;

[0015] One end of the intermediate sleeve passes through the base plate, and the other end is connected to the air chamber cavity;

[0016] The upper surface of the air chamber cavity has two arc-shaped air channels, which are respectively connected to the vertical blowing hole and the inclined blowing hole;

[0017] The two arc-shaped air passages are concentrically arranged with different arc radii and are staggered so that the air chamber cavity is selectively connected to the vertical blowing hole or the inclined blowing hole.

[0018] Furthermore, the plug supply and air blowing mechanism includes a first sleeve, a conveying wheel and an air supply plug receiving disc;

[0019] The first sleeve is rotatably mounted on the outside of the middle sleeve;

[0020] The conveying wheel is fixedly mounted on the outer wall of the first sleeve and has a plurality of notches for synchronously driving the bottle body to rotate;

[0021] The air supply plug disc is fixedly mounted on the top of the first sleeve, and the lower surface thereof is in contact with the air chamber cavity;

[0022] The vertical air blowing holes and the inclined air blowing holes are both arranged inside the air supply plug disc and are located in the same horizontal plane;

[0023] When the first sleeve rotates, the vertical blowing hole and the inclined blowing hole are switchedly connected to one of the arc-shaped air channels;

[0024] The accommodating groove is arranged at the edge of the lower surface of the air supply plug plate, and one side is set as an opening and corresponds to the notch one by one.

[0025] Furthermore, the lifting and rotating bottle supporting mechanism includes a second sleeve, a fixing ring and a plurality of lifting brackets;

[0026] The second sleeve is arranged on the outer wall of the first sleeve and is used to drive the first sleeve to rotate synchronously;

[0027] The fixing ring is fixedly mounted on the outer wall of the second sleeve;

[0028] The plurality of lifting brackets are slidably installed inside the fixing ring along a vertical direction.

[0029] Furthermore, a fixed gear ring is provided on the outside of the second sleeve to be connected to an external driving device to control the rotation of the second sleeve.

[0030] Furthermore, a supporting component is fixedly mounted on the base plate, and the supporting component overlaps with the bottom ends of the plurality of lifting brackets;

[0031] When the lifting brackets are rotated by the rotational power of the second sleeve, the plurality of lifting brackets rise or fall periodically under the action of the supporting component.

[0032] Furthermore, the supporting component includes a third sleeve and a boss;

[0033] The third sleeve is fixedly mounted on the base plate and sleeved on the outside of the second sleeve;

[0034] The boss is fixedly mounted on the outer wall of the third sleeve, and the upper surface is configured as an annular closed curved surface formed by a first rising section, a descending buffer section, a second rising section, and a descending smooth section.

[0035] Furthermore, when the bottom end of the lifting bracket is placed at the lowest point of the descending buffer section, the air outlet end of the air supply mechanism is just switched to be connected with the inclined blowing hole, and the receiving groove corresponding to the lifting bracket also just extracts the bottle stopper on the stopper sorting mechanism.

[0036] Furthermore, when the bottom end of the lifting bracket is placed in the first ascending section, the lifting bracket gradually moves in a direction close to the vertical blowing hole, so that the inert gas is blown into the bottle body through the vertical blowing hole;

[0037] When the bottom end of the lifting bracket is placed on the descending buffer section, the lifting bracket gradually moves away from the vertical blowing hole;

[0038] When the bottom end of the lifting bracket is placed in the second ascending section, the inclined blowing hole always blows air to the junction of the bottle body and the bottle stopper until the lifting bracket pulls the bottle body to be combined with the bottle stopper placed in the receiving groove;

[0039] When the bottom end of the lifting bracket is placed on the descending smooth section, the bottle body carrying the bottle plug in the receiving groove is separated from the receiving groove.

[0040] In another aspect, the present invention further provides a gas supply plugging method, which is applied to any of the gas supply plugging devices described above, comprising the following steps:

[0041] Control the lifting and rotating bottle supporting mechanism and the plug supply and blowing mechanism to rotate synchronously, drive the bottle body located at the initial station to rotate and transport, and make the bottle body experience at least two rises and falls during the rotation process;

[0042] During the first gradual ascent and descent of the bottle body, the vertical air blowing hole is controlled to be in communication with the air outlet end of the air supply mechanism so as to always inject inert gas into the interior of the bottle body;

[0043] When the bottle body descends to the bottom for the first time, the plug supply and blowing mechanism is controlled to extract the bottle plugs in the plug sorting mechanism into the receiving groove corresponding to the bottle body, and at the same time, the inclined blowing hole is switched to be connected to the air outlet end of the air supply mechanism;

[0044] During the second ascent of the bottle body, the inclined blowing hole is controlled to always inject inert gas into the joint position between the bottle body and the bottle stopper in the receiving groove until the bottle body and the bottle stopper are combined;

[0045] During the second descent of the bottle body, the interaction force formed by the combination of the bottle body and the bottle stopper is used to overcome the friction between the inner wall of the receiving groove and the bottle stopper, so that the stoppered bottle body is separated from the receiving groove, and the stoppering is completed.

[0046] Compared with the prior art, the present invention has at least the following beneficial effects:

[0047] By utilizing the lifting and rotating bottle supporting mechanism to drive the bottle body to rise or fall when rotating, and the vertical blowing hole and the inclined blowing hole of the plug supply and blowing mechanism are selectively connected with the air outlet end of the air supply mechanism, before the bottle body is combined with the bottle stopper, the vertical blowing hole can continue to blow air into the bottle body to reduce the oxygen content inside the bottle body. Then, when the inclined blowing hole is switched to be connected with the air outlet end of the air supply mechanism, the receiving groove provided on the plug supply and blowing mechanism can just extract the bottle stopper in the plug sorting mechanism, so that the bottle stopper is located just above the bottle body. At this time, the inclined blowing hole always blows air into the combination position of the bottle stopper and the bottle body until the bottle body rises to be combined with the bottle stopper under the power action of the lifting and rotating bottle supporting mechanism. That is, in the process of the bottle body and the bottle stopper being combined, the bottle body is always injected with inert gas, and the oxygen content in the bottle body will not be too high due to the idle period, so as to achieve the purpose of reducing nitrogen use and reducing the residual oxygen content in the bottle body after stoppering. The stoppering and continuous air supply are combined to effectively improve the stoppering rate of the bottle. BRIEF DESCRIPTION OF THE DRAWINGS

[0063] The following is a more detailed description of the gas supply plugging device and gas supply plugging method of the present invention, with reference to schematic diagrams. Preferred embodiments of the present invention are shown, and it should be understood that those skilled in the art may modify the present invention described herein while still achieving the advantageous effects of the present invention. Therefore, the following description should be understood as a general guide for those skilled in the art and not as a limitation of the present invention.

[0064] The following paragraphs describe the present invention in more detail by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the drawings are greatly simplified and not to exact scale, and are provided solely for the purpose of assisting in the description of the embodiments of the present invention.

[0065] Example 1

[0066] like Figure 1 and Figure 2 As shown, an embodiment of the present invention proposes an air supply plugging device and an air supply plugging method, including a substrate 1, a plugging arrangement mechanism 2, an air supply mechanism 3, a plugging blowing mechanism 4, and a lifting and rotating bottle supporting mechanism 5.

[0067] The plug sorting mechanism 2 is arranged on one side of the substrate 1. In this embodiment, the plug sorting mechanism 2 can be set as a vibrating plug sorter in the prior art.

[0068] The gas supply mechanism 3 is provided on the substrate 1 and is used to provide inert gas to cooperate with the subsequent plug blowing mechanism 4 to reduce the oxygen content inside the bottle body.

[0069] The stopper supply and blowing mechanism 4 is arranged on the substrate 1 and can rotate relative to the air supply mechanism 3, and has a vertical blowing hole 431 and an inclined blowing hole 432. The stopper is driven to rotate by rotation to complete the stopper removal function, and the vertical blowing hole 431 and the inclined blowing hole 432 are used to inject inert gas into the bottle body in two states (such as before and after combination with the stopper) to avoid a window period, which causes external oxygen to flow back into the bottle body, thereby increasing the oxygen content of the bottle body.

[0070] In addition, when the stopper air supply mechanism 4 rotates, the air outlet end of the air supply mechanism 3 is selectively connected to the vertical air blowing hole 431 or the inclined air blowing hole 432, that is, when the stopper air supply mechanism 4 rotates, the air supply mechanism 3 is only connected to one of the vertical air blowing hole 431 and the inclined air blowing hole 432, thereby avoiding waste of inert gas and preventing interference with the extraction of the cork.

[0071] Specifically, the vertical blowing hole 431 is also provided with a receiving groove 433 for extracting the bottle cork on the cork sorting mechanism 2, that is, when the bottle cork is taken out, the vertical blowing hole 431 can be disconnected from the gas outlet end of the gas supply mechanism 3 to avoid direct blowing of gas causing the bottle cork to separate from the receiving groove 433.

[0072] It should be noted that the accommodating groove 433 and the bottle stopper should be completed by interference fit, and the stopper sorting mechanism 2 and the stopper supply and blowing mechanism 4 can use the form of a track to supply the bottle stopper to the stopper supply and blowing mechanism 4 to achieve uninterrupted supply of bottle stoppers.

[0073] The lifting and rotating bottle supporting mechanism 5 is provided on the base plate 1 and is capable of rotating synchronously with the stopper supply and air blowing mechanism 4. During the rotation, the bottle on the lifting and rotating bottle supporting mechanism 5 can be raised or lowered. In other words, the lifting and rotating bottle supporting mechanism 5 is provided as the main power source to drive the stopper supply and air blowing mechanism 4 to rotate, thereby achieving synchronous rotation of the stopper and the bottle body, facilitating docking. Moreover, during the rotation, the movement of the bottle body can be controlled to achieve the connection between the bottle body and the stopper, completing the stoppering and air injection function.

[0074] The device utilizes the lifting and rotating bottle supporting mechanism 5 to drive the bottle body to rise or fall when rotating, and the vertical blowing hole 431 and the inclined blowing hole 432 of the plug supply and blowing mechanism 4 are selectively connected with the air outlet end of the air supply mechanism 3, so that before the bottle body is combined with the bottle stopper, the vertical blowing hole 431 can blow air into the inside of the bottle body to reduce the oxygen content inside the bottle body, and then when the inclined blowing hole 432 is switched to be connected with the air outlet end of the air supply mechanism 3, the accommodating groove 433 provided on the plug supply and blowing mechanism 4 can just extract the oxygen in the plug sorting mechanism 2. The bottle stopper is placed right above the bottle body, and the inclined blowing hole 432 is always blowing air to the joint position between the bottle stopper and the bottle body until the bottle body rises to be combined with the bottle stopper under the power of the lifting and rotating bottle supporting mechanism 5. That is, in the process of the bottle body and the bottle stopper being combined, the bottle body is always injected with inert gas, and the oxygen content in the bottle body will not be too high due to the idle period, so as to achieve the purpose of reducing nitrogen usage and reducing the residual oxygen content in the bottle body after stoppering, and combining the stoppering with the continuous gas supply can effectively improve the bottle stoppering rate.

[0075] like Figure 2 and Figure 3 As shown, in this embodiment, a specific gas supply mechanism 3 is provided to better provide inert gas.

[0076] Specifically, the air supply mechanism 3 includes a middle sleeve 31 and an air chamber cavity 32 .

[0077] One end of the intermediate sleeve 31 passes through the substrate 1 , and the other end is connected to the air chamber cavity 32 .

[0078] The upper surface of the air chamber cavity 32 has two arc-shaped air channels 321 to communicate with the vertical blowing hole 431 and the inclined blowing hole 432 respectively.

[0079] It should be noted that the two arc-shaped air channels 321 are concentrically arranged with different arc radii and are staggered so that the air chamber cavity 32 can selectively communicate with the vertical air blowing hole 431 or the inclined air blowing hole 432. That is, when the plug supply and blowing mechanism 4 is driven by the lifting and rotating bottle supporting mechanism 5 to rotate relative to the air supply mechanism 3, the vertical air blowing hole 431 in the plug supply and blowing mechanism 4 can only communicate with the outermost arc-shaped air channel 321 or the inclined air blowing hole 432 with the inner arc-shaped air channel 321. This can achieve the function of the air outlet end of the air chamber cavity 32 communicating with only one of the vertical air blowing hole 431 and the inclined air blowing hole 432, that is, alternatingly blowing air into the bottle body.

[0080] It should be noted that the two arc-shaped air passages 321 are designed to be continuous, ensuring that no window period is formed during alternation, thereby ensuring the blowing effect on the bottle body.

[0081] like Figure 4 and Figure 5 As shown, in a further embodiment, a specific stopper blowing mechanism 4 is proposed to further limit the positions of the vertical blowing holes 431, the inclined blowing holes 432 and the accommodating grooves 433, so that the bottle body and the stopper can be combined more accurately and the air supply effect can be better.

[0082] The plug supply and air blowing mechanism 4 includes a first sleeve 41 , a conveying wheel 42 and an air supply and plug connection plate 43 .

[0083] The first sleeve 41 is rotatably mounted on the outside of the middle sleeve 31 , that is, the first sleeve 41 rotates relative to the middle sleeve 31 without interfering with the middle sleeve 31 .

[0084] The conveying wheel 42 is fixedly mounted on the outer wall of the first sleeve 41 and has a plurality of notches for synchronously driving the bottle body to rotate, so as to position the bottle body.

[0085] It should be noted that if Figure 1 As shown, a railing is further provided on the outside of the conveying wheel 42 to limit the position of the bottle.

[0086] The air supply plug disc 43 is fixedly mounted on the top of the first sleeve 41 , and its lower surface is in contact with the air chamber cavity 32 , ensuring that the inert gas in the air chamber cavity 32 does not escape.

[0087] The vertical air blowing holes 431 and the inclined air blowing holes 432 are both arranged inside the air supply plug plate 43 and located in the same horizontal plane to cooperate with the two arc-shaped air channels 321 to quickly switch the air paths.

[0088] Specifically, when the first sleeve 41 rotates, the vertical blowing holes 431 and the inclined blowing holes 432 are switchedly connected to one of the arc-shaped air channels 321 .

[0089] like Figure 5 As shown, in addition, the accommodating groove 433 is arranged at the edge of the lower surface of the air supply plug plate 43, and one side is set to be open and corresponds one-to-one with the notch, that is, a single bottle body corresponds to a bottle plug, ensuring the accuracy when the two are subsequently combined.

[0090] It should be noted that the inner diameter of the receiving groove 433 decreases from the outside to the inside, so that when the bottle stopper receiving mechanism 2 and the track running power are placed deep inside the receiving groove 433, they can be engaged inside the receiving groove 433 by interference.

[0091] like Figure 6 As shown, in other embodiments, a specific lifting and rotating bottle supporting mechanism 5 is also proposed to drive the bottle body to rotate and control the docking of the bottle body and the bottle stopper.

[0092] Specifically, the lifting and rotating bottle supporting mechanism 5 includes a second sleeve 51 , a fixing ring 52 and a plurality of lifting brackets 53 .

[0093] The second sleeve 51 is disposed on the outer wall of the first sleeve 41 and is used to drive the first sleeve 41 to rotate synchronously, such as by using a keyway engagement method to complete the synchronous rotation of the second sleeve 51 and the first sleeve 41.

[0094] The fixing ring 52 is fixedly mounted on the outer wall of the second sleeve 51 and is used to position and support the lifting bracket 53 .

[0095] The plurality of lifting brackets 53 are slidably installed in the fixing ring 52 along the vertical direction, and are used to drive the bottle body to rise and fall in the vertical direction.

[0096] In addition, a fixed gear ring 511 is provided on the outside of the second sleeve 51 to connect with an external driving device to control the rotation of the second sleeve 51 .

[0097] It should also be noted that in order to enable the present device to be suitable for use with bottles of different heights, the first sleeve 41 and the second sleeve 51 are enabled to move relative to each other in the vertical direction, thereby changing the distance between the air supply plugging plate 43 and the lifting bracket 53, thereby meeting the application requirements of plugging bottles of different heights.

[0098] It should be noted that when adjusting the height of the first sleeve 41, the intermediate sleeve 31 should be moved synchronously to ensure that the air chamber cavity 32 is always in contact with the gas supply plug disk 43 to ensure the normal supply and output of the inert gas. The specific adjustment method can be used to cooperate and constrain components such as the screw in the existing technology, so it will not be elaborated here.

[0099] like Figure 1 、 Figure 7 、 Figure 8 as well as Figure 9 As shown, in this embodiment, a support member 6 is further provided to cooperate with the lifting bracket 53 to complete the height adjustment of the bottle body. The support member 6 is fixedly mounted on the base plate 1 and overlapped with the bottom ends of the plurality of lifting brackets 53.

[0100] When the lifting brackets 53 are rotated by the rotational force of the second sleeve 51 , the plurality of lifting brackets 53 are periodically raised or lowered under the action of the supporting component 6 .

[0101] Specifically, the supporting component 6 includes a third sleeve 61 and a boss 62 .

[0102] The third sleeve 61 is fixedly mounted on the substrate 1 and sleeved on the outside of the second sleeve 51 .

[0103] The boss 62 is fixedly mounted on the outer wall of the third sleeve 61 , and the upper surface is configured as an annular closed curved surface formed by a first rising section 621 , a descending buffer section 622 , a second rising section 623 and a descending smooth section 624 .

[0104] It should be noted that when the bottom end of the lifting bracket 53 is placed at the lowest point of the descending buffer section 622, the air outlet end of the air supply mechanism 3 is just switched to be connected with the inclined blowing hole 432, and the receiving groove 433 corresponding to the lifting bracket 53 also just extracts the bottle stopper on the plug sorting mechanism 2.

[0105] like Figure 9 As shown in the left figure, when the bottom end of the lifting bracket 53 is placed on the first ascending section 621, the lifting bracket 53 gradually moves in a direction close to the vertical blowing hole 431, so that the inert gas is blown into the bottle body through the vertical blowing hole 431.

[0106] And when the bottom end of the lifting bracket 53 is placed on the descending buffer section 622, the lifting bracket 53 gradually moves away from the vertical blowing hole 431 to wait for the subsequent combination with the bottle stopper.

[0107] like Figure 9 As shown in the right figure, when the bottom end of the lifting bracket 53 is placed on the second rising section 623, the inclined blowing hole 432 always blows air to the junction between the bottle body and the cork until the lifting bracket 53 pulls the bottle body to combine with the cork placed in the receiving groove 433.

[0108] Then, when the bottom end of the lifting bracket 53 is placed on the descending smooth section 624 , the bottle body carrying the bottle plug in the receiving groove 433 is separated from the receiving groove 433 .

[0109] Example 2

[0110] like Figure 10 As shown, on the other hand, the present invention also proposes a gas supply and plugging method to reduce the oxygen content in the bottle and improve the processing rate.

[0111] A gas supply plugging method specifically comprises the following steps:

[0112] The lifting and rotating bottle supporting mechanism 5 is controlled to rotate synchronously with the stopper supply and blowing mechanism 4, driving the bottle body located at the initial work station to rotate and transport, and making the bottle body experience at least two rises and falls during the rotation process, so as to respectively complete the direct blowing of the inert gas into the inside of the bottle body and the blowing of the inert gas to the joint position of the bottle body and the stopper.

[0113] During the first gradual ascent and descent of the bottle body, the vertical blowing hole 431 is controlled to be connected to the gas outlet of the gas supply mechanism 3 so as to always inject inert gas into the bottle body, thus completing the initial blowing of the bottle body.

[0114] When the bottle body drops to the bottom for the first time, the plug supply and blowing mechanism 4 is controlled to extract the bottle plug in the plug sorting mechanism 2 into the receiving groove 433 corresponding to the bottle body, and at the same time, the inclined blowing hole 432 is switched to be connected to the air outlet end of the air supply mechanism 3, completing the switching of the air path and the extraction of the bottle plug, waiting for the subsequent docking of the bottle body and the bottle plug.

[0115] During the second rising process of the bottle body, the inclined blowing hole 432 is controlled to always inject inert gas into the joint position between the bottle body and the bottle stopper in the receiving groove 433 until the bottle body and the bottle stopper are combined.

[0116] During the second descent of the bottle body, the interaction force formed by the combination of the bottle body and the bottle stopper is used to overcome the friction between the inner wall of the receiving groove 433 and the bottle stopper, so that the stoppered bottle body is separated from the receiving groove 433, and the stoppering is completed.

[0117] Through the above steps, air can be continuously supplied to the bottle and the bottle mouth on a one-to-one basis, and air can be continuously supplied to the junction of the bottle body and the stopper, which can effectively reduce the use of inert gas and reduce the residual oxygen content in the bottle body after stoppering. Combining stoppering with continuous air supply can effectively increase the bottle stoppering rate.

[0118] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
