In the related art, a glue supply device for supplying lap glue to a cigarette making machine comprises a glue barrel and a gas source, wherein the glue barrel is connected with the gas source and a glue spraying nozzle of the cigarette making machine, and glue solution is directly filled in the glue barrel. In the working process, high-pressure gas is introduced into the glue barrel from the gas source to drive the glue solution in the glue barrel to flow to the glue spraying nozzle, the glue spraying nozzle is used for gluing the lap opening of the cigarette paper wrapping the cigarette tows, the lap opening is closed to form longer cigarette strips, and then the cigarette strips are cut to form shorter cigarettes.
Under the above conditions, the glue solution directly contacts with the air, especially directly contacts with the high-pressure gas supplied by the gas source for a long time, the moisture in the glue solution evaporates faster, and is easy to dry or agglomerate, so that deterioration occurs, on one hand, the deteriorated glue solution easily affects the bonding effect of the lap joint, causes the problems of cigarette bursting and strip running failure of cigarette equipment, and causes serious product quality problems, on the other hand, the glue block easily blocks the pipeline or the glue nozzle in the process of flowing through the pipeline and entering the glue nozzle, so that the glue discharging is not smooth, the smoothness of the production process is affected, and the product quality is also easily affected, on the other hand, the glue agglomerates on the wall of the glue barrel, and the glue barrel needs to be frequently cleaned, not only after a period of equipment production cycle, the glue barrel needs to be cleaned, and when the equipment stops production in a workshop, the glue barrel also needs to be cleaned when the equipment is stopped for a long time, which not only increases the maintenance cost of the equipment, meanwhile, the residual glue solution in the glue barrel must be poured out in the cleaning process of the glue barrel and then cleaned by a large amount of clear water, so that waste of the glue solution, water resources and human resources is caused, and the pollution of the glue solution to the environment is also caused.
In addition, in the above related art, when the glue solution in the glue barrel is insufficient and needs to be added, after the air source is cut off, the worker pulls out the air pipe connector at the edge of the barrel cover, releases the residual high-pressure air in the glue barrel, opens the barrel cover, pours the glue into the glue barrel to complete the glue adding task, and in the glue adding process, the worker needs to control the liquid level of the glue solution, the process is complex, and the efficiency is low.
Therefore, based on the related technology, the glue solution is easy to go dry or agglomerate and other deterioration problems, so that the smoothness of the production process is affected, the cost of equipment maintenance is increased, the waste of resources is caused, meanwhile, the quality of cigarette products is also affected, the automatic exhaust and automatic glue adding functions cannot be realized, the glue adding efficiency is lower, and the operation safety is poorer.
In view of this, the invention provides a glue storage device and a glue conveying system comprising the same, which reduce the deterioration risk of glue solution, improve the glue adding efficiency and enhance the safety of glue adding operation by improving the glue solution storage device and the like.
Fig. 1-2 illustrate one embodiment of a glue delivery system of the present invention.
Referring to fig. 1-2, in some embodiments of the present invention, the glue conveying system includes a glue storage device, an air source 4, a glue adding device, and the like, and both the glue storage device and the glue adding device are connected to the air source 4, so that under the action of the same air source 4, the glue conveying system can not only achieve an automatic glue supplying function of automatically supplying glue to a glue spraying nozzle 5 of a cigarette making machine, but also achieve an automatic glue adding function of automatically adding glue to the glue storage device.
As shown in fig. 1, the glue storage device includes a first glue barrel 1 and a glue bag 2. The first glue barrel 1 is provided with an air inlet 11, and the air inlet 11 is connected with an air source 4 through a first air pipe 81. The glue bag 2 is arranged in the first glue barrel 1 and used for storing glue solution (i.e. lap glue), and the bag opening 21 of the glue bag is connected with the glue nozzle 5 through a first glue tube 82. Specifically, the first glue barrel 1 may be slidably disposed on the base, for example, so that the worker may push and pull the first glue barrel 1 to separate the first glue barrel 1 from the base or reset the first glue barrel. The glue bag 2 may be made of transparent PVC plastic, for example, and the bag opening 21 may extend from the glue outlet 12 of the first glue barrel 1 and be connected to the first glue tube 82. More specifically, the air inlet 11 and the glue outlet 12 may be located at the top and bottom of the first glue barrel 1, respectively. The top of the barrel is also provided with a barrel cover.
Based on the above arrangement, in the glue supplying process, the air source 4 can supply air to the first glue barrel 1 through the first air pipe 81, the high-pressure gas flowing into the first glue barrel 1 extrudes the glue bag 2, so that the glue solution in the glue bag 2 flows out from the glue bag 2, flows to the glue spraying nozzle 5 through the first glue pipe 82, is sprayed out to the lap of the cigarette paper wrapping the cigarette bundle by the glue spraying nozzle 5, and is bonded to the lap.
In the above glue supplying process, the glue bag 2 can play a role in sealing and isolation, so that the glue solution can realize a pneumatic glue supplying function without directly contacting with high-pressure gas supplied by the gas source 4, and meanwhile, in a non-glue supplying process, for example, in a storage process of stopping production in a workshop and the like for a long time, the glue bag 2 can also play a role in sealing and isolation, so that the glue solution cannot be directly exposed in the air, therefore, the evaporation of water in the glue solution can be effectively slowed down, the risk of deterioration problems such as drying or caking of the glue solution and the like is reduced, the storage time of the glue solution is prolonged, the blockage of a pipeline, a glue spraying nozzle 5 and the like can be reduced, the occurrence of unqualified products such as a sudden opening or a strip is reduced, the smoothness of the production process is guaranteed, and the quality of finished products is improved.
Meanwhile, under the sealing and isolating action of the rubber bag 2, the rubber solution is not in direct contact with the first rubber barrel 1 any more, and the evaporation speed of water in the rubber solution is obviously slowed down, so that the rubber solution can be prevented from being fixedly connected to the inner wall of the first rubber barrel 1, the cleaning and maintenance frequency of the first rubber barrel 1 is favorably reduced, and the maintenance-free and cleaning-free operation of the first rubber barrel 1 is particularly favorably realized under the condition that the equipment is shut down for a long time, so that the water resource, the human resource and the rubber resource are effectively saved, the waste is reduced, the cost is saved, and the pollution to the environment is reduced.
Obviously, the glue solution is stored by additionally arranging the independent glue bag 2 in the first glue barrel 1, so that the glue storage device can realize the closed storage of the glue solution by utilizing the sealing and isolating effect of the glue bag 2, the glue solution is prevented from being directly exposed in air or high-pressure gas provided by the gas source 4, the water evaporation of the glue solution is slowed down, the risk of drying or caking of the glue solution is reduced, the storage time of the glue solution is prolonged, the cleaning and maintenance frequency of equipment is reduced, and the resource waste and the environmental pollution are reduced.
The gas source 4 is typically a long-pass gas source, i.e. it is always working in a normal state. In the illustrated embodiment, the air source 4 is connected to both the glue storage device and the glue adding device, so that the air source 4 becomes a power source of the whole glue conveying system, and the air source, together with the glue storage device and the like, forms a glue supply system to be used as a power source of the glue supply system, and also, together with the glue adding device and the like, forms a glue adding system to be used as a power source of the glue adding system.
Wherein, the air source 4 is connected with the glue storage device in a break-make way. Specifically, as shown in fig. 1, a first control valve 91 is disposed on the first air pipe 81, and the first control valve 91 is used for controlling the on/off of the first air pipe 81. The first control valve 91 may be, for example, a two-position three-way control valve, but this does not limit the first control valve 91, and for example, the first control valve 91 may also be a manual control valve, an electric control valve, or a hydraulic control valve. Based on the arranged first control valve 91, in the glue supplying process, the first control valve 91 can control the first air pipe 81 to be communicated, so that the air source 4 can smoothly supply air to the glue storage device and provide driving force for the glue solution to flow; in the other non-glue-supplying processes such as glue adding or production stopping, the first control valve 91 can control the first air pipe 81 to be disconnected, so that the air source 4 stops supplying air to the glue storage device, on one hand, the potential safety hazard caused by continuous ventilation to the first glue barrel 1 in the non-glue-supplying process can be avoided, and the safety of the non-glue-supplying process is enhanced, on the other hand, the influence of high-pressure air in the first glue barrel 1 on the glue adding process is also convenient to reduce, and the point is described by combining the introduction of the glue supplying device.
As shown in fig. 2, in some embodiments of the present invention, the glue applying device is disposed on the moving carriage 7 and includes a second glue barrel 61, a pneumatic pump 62, and the like. The second glue barrel 61 is used for storing glue solution. The pneumatic pump 62 is connected to the second glue barrel 61 and the bag opening 21, and is used for driving the glue solution to flow from the second glue barrel 61 to the glue bag 2. The pneumatic pump 62 can be connected with the bag opening 21 through a second rubber tube 84, and is connected with the second rubber barrel 61 through a third rubber tube 88. The travelling carriage 7 may be a trolley or may be an autonomous travelling carriage. Specifically, as shown in fig. 1, the second hose 84 may be connected to the first hose 82 through a three-way joint 87, so as to connect to the bag 2.
When the glue solution in the glue storage device is insufficient, the glue adding device can be transported to the position near the glue storage device by using the movable trolley 7, the pneumatic pump 62 is started, and the glue solution in the second glue barrel 61 is pressed into the glue bag 2 by using the pneumatic pump 62 to supplement the glue solution for the glue storage device.
It can be seen that, under the effect of pneumatic pump 62 and second gluey bucket 61, it is automatic to add the mucilage binding and puts to add the mucilage binding, can realize adding the gluey function automatically, and under the effect of travelling car 7, it is portable to add the mucilage binding and puts to add the mucilage binding, uses the flexibility higher.
The pneumatic pump 62 is used as a driving device, and plays a role in driving glue liquid to flow in the glue adding process. The pneumatic pump 62 uses compressed air as a power source, can deliver various liquids such as corrosive liquids, liquids with particles, highly viscous, volatile, flammable or highly toxic liquids, and the like, and has various advantages of high energy utilization rate, low leakage risk, and the like.
As previously mentioned, in the illustrated embodiment, the gas that drives the operation of the pneumatic pump 62 is derived from the gas source 4. Specifically, the pneumatic pump 62 is connected to the gas source 4 through a second gas pipe 83. Thus, when glue needs to be added, the air source 4 can supply air for the pneumatic pump 62, and the automatic glue adding process is smoothly realized. Because the glue adding device and the glue storage device use the same air source 4 as a power source, the structure is simpler, and the cost is lower.
Of course, in the embodiment not shown, the pneumatic pump 62 may be additionally provided with a special air source; even, the driving device may also adopt other conveying apparatuses than the pneumatic pump 62, such as an electric pump or a magnetic force driven pump, and the power source of the driving device is no longer an air source, but may be other power apparatuses such as an electric motor.
When the same air source 4 is used for supplying air to the glue storage device and the glue adding device, as shown in fig. 1, a pressure regulating valve 93 can be arranged on a connecting pipeline (namely, the second air pipe 83) between the air source 4 and the pneumatic pump 62 to regulate the pressure of the air flowing from the air source 4 to the pneumatic pump 62, so that the air pressure provided by the air source 4 for the pneumatic pump 62 better meets the requirements of the pneumatic pump 62, and the air source 4 is convenient to meet the different air pressure requirements of the glue storage device and the glue adding device.
In order to control the air supply 4 to supply air to the glue adding device when the glue solution in the glue storage device is insufficient, as shown in fig. 1, the glue conveying system further comprises a glue level detection device 3 for detecting the liquid level of the glue solution in the glue bag 2 and a second control valve 94 for controlling the on-off of the second air pipe 83.
Specifically, as can be seen from fig. 1, the glue level detecting device 3 is a glue level detector, which is disposed in the first glue barrel 1 and located outside the glue bag 2, and detects the liquid level of the glue solution in the glue bag 2 by detecting the height of the top end of the glue bag 2. Therefore, the glue level detection device 3 realizes indirect detection of the liquid level of the glue solution by detecting the height of the glue bag 2. Because the glue level detection device 3 can detect the liquid level of the glue solution in the glue bag 2 in real time, the remaining situation of the glue solution can be known more conveniently, timely and accurately without manually exploring the remaining situation of the glue solution in the glue storage device, and meanwhile, the glue level detection device can be matched with the second control valve 94 to implement automatic glue adding work more timely. Moreover, the glue position detection device 3 can realize the glue position detection function without extending into the glue bag 2, so that the integrity and the tightness of the glue bag 2 can be kept without damaging the structure of the glue bag 2, the glue bag 2 can better play a role in sealing and isolating, and the dryness or caking of glue solution can be effectively reduced.
The second control valve 94 is disposed on the second air tube 83, electrically connected to the glue level detection device 3, and configured to control the second air tube 83 to communicate when the glue level detection device 3 detects that the liquid level of the glue solution in the glue bag 2 is lower than a preset value. The second control valve 94 may be, for example, a two-position, three-way solenoid valve. The broken line in fig. 1 indicates the electrical connection relationship between the glue level detecting device 3 and the second control valve 94.
Based on the above arrangement, when the glue level detection device 3 detects that the liquid level of the glue solution in the glue bag 2 is higher than the preset value, it indicates that the glue solution in the glue storage device still meets the requirement, and the glue solution does not need to be filled into the glue storage device, therefore, the second control valve 94 controls the second air pipe 83 to be disconnected, so that the air source 4 cannot supply air to the pneumatic pump 62, the pneumatic pump 62 does not work, and the glue filling device does not perform a glue filling task; when the glue level detection device 3 detects that the liquid level of the glue solution in the glue bag 2 is lower than the preset value, it indicates that the glue solution in the glue storage device is too low, and the glue solution needs to be supplemented to the glue bag 2, at this time, the second control valve 94 can control the second air pipe 83 to be communicated according to the detection result of the glue level detection device 3, so that the air source 4 can supply air to the pneumatic pump 62, the pneumatic pump 62 is started, and the glue adding task is started; meanwhile, in the glue adding process, the glue position detection device 3 can also monitor the glue position in real time, and when the glue position reaches the preset value again, the second control valve 94 can be informed to cut off the second air pipe 83 to stop the pneumatic pump 62, so that excessive glue adding is avoided.
It can be seen that under the cooperation of the glue position detection device 3 and the second control valve 94, the glue conveying system can realize automatic detection of the glue position in the glue bag 2, automatic control of whether the gas supply of the glue adding device is available, and automatic control of start and stop of the glue adding process. Because whether glue needs to be added or whether glue needs to be stopped is not judged manually, and glue liquid does not need to be poured into the glue storage device manually, the glue adding process can be realized more timely and efficiently.
In the glue adding process, if there are more high-pressure gases in the first glue barrel 1, the glue adding difficulty is increased, and even the glue adding failure is caused to solve the problem, on one hand, the first control valve 91 can be utilized to cut off the gas path between the gas source 4 and the first glue barrel 1 as described above, so that no new high-pressure gas is introduced into the first glue barrel 1, and the high-pressure gas is prevented from being accumulated continuously, and the glue adding smoothness is influenced, on the other hand, the first gas pipe 81 can be further provided with an exhaust device as shown in fig. 1, and the exhaust device is used for automatically exhausting the gas in the first glue barrel 1, so that the influence of the high-pressure gas in the first glue barrel 1 on the glue adding process is reduced through exhaust. Like this, can trigger first control valve 91 earlier and stop the air feed of air supply 4 to first gluey bucket 1 before adding glue to utilize exhaust apparatus with the first interior remaining high-pressure gas of gluing bucket 1 discharge, with the high-pressure gas influence that prevents in the first bucket 1 of gluing add the normal implementation of gluey process, reduce and add the gluey degree of difficulty, improve and add gluey smooth and easy nature. Moreover, the exhaust device can realize the automatic control of the exhaust process, and the exhaust start and stop are not required to be controlled by manually plugging the air pipe, so that the exhaust operation is simpler, the risk that workers are injured by high-pressure gas in the exhaust process is reduced, and the personal safety of the workers is improved.
As shown in fig. 1, the exhaust means may include, for example, a quick exhaust valve 92 provided on the first air pipe 81.
The quick exhaust valve 92 is a valve capable of realizing quick exhaust of gas, and the hydraulic principle thereof is as shown in fig. 3, the gas inlet P, the working gas inlet a and the exhaust port T are respectively connected with a gas supply source, an actuator and the atmosphere, and the working gas inlet a is switchably communicated with the gas inlet P and the exhaust port T according to whether the gas inlet P is filled with compressed air or not, wherein, when the gas inlet P is filled with compressed gas, the working gas inlet a is communicated with the gas inlet P and disconnected with the exhaust port T, so that external gas can enter the actuator through the gas inlet P and the working gas inlet a, but gas in the actuator cannot flow out to the atmosphere through the exhaust port T, at this time, the quick exhaust valve 92 is at a first valve position, and can realize a normal ventilation function to the actuator, and when the gas inlet P is not filled with compressed gas, the working gas inlet a is communicated with the exhaust port T and disconnected with the gas inlet P, so that the external air can not enter the actuator any more, but the air in the actuator is rapidly exhausted through the working air port a and the exhaust port T, and at this time, the rapid exhaust valve 92 is in the second valve position, thereby realizing the rapid exhaust function. Based on this, as can be seen from fig. 1, in the present invention, the inlet P of the quick exhaust valve 92 is connected to the air source 4, the working inlet a of the quick exhaust valve 92 communicates with the inlet 11, and the outlet T of the quick exhaust valve 92 communicates with the atmosphere.
Based on the above setting, in the normal glue supply process, because air supply 4 keeps for first gluey bucket 1 air feed, quick vent valve 92's income gas port P has compressed air to let in all the time, therefore, quick vent valve 92 keeps in first valve position, it can normally communicate air supply 4 and first gluey bucket 1, guarantee that high-pressure gas gets into first gluey bucket 1 in, drive glue solution flow direction spouts gluey mouth 5, and need to add gluey or under the non-glue supply circumstances such as long-time stop production, because air supply 4 stops to first gluey bucket 1 air feed, quick vent valve 92's income gas port P no longer has compressed air, consequently, quick vent valve 92 automatic switch to second valve position, with the automatic atmospheric air of remaining high-pressure gas in the first gluey bucket 1 of discharging.
It can be seen that quick exhaust valve 92 can control and realize the automatic exhaust function according to whether air supply 4 supplies air for first gluey bucket 1, neither influence normal confession gluey process, can conveniently add implementation of gluey work again.
Specifically, as shown in fig. 1, the quick exhaust valve 92 may be disposed between the first control valve 91 and the air inlet 11, so that the quick exhaust valve 4 may determine whether the air source 4 supplies air to the first glue barrel 1 according to on-off control of the first control valve 91 on the first air pipe 81, and then conveniently control whether to execute an automatic exhaust task.
