Description

Technical Field

[0001] The invention belongs to the technical field of cigarette production, and in particular relates to a device and method for preventing a cigarette conveying channel from being blocked. Background Art

[0002] In the cigarette production process, the cigarettes rolled by the rolling machine are transported to the packaging machine through the cigarette storage and conveying system for subsequent packaging processes. In the actual production process, the packaging machine or the rolling machine will stop. In order to avoid the shutdown of the entire unit due to the shutdown, during the shutdown of the packaging machine, the cigarettes will be transported to the cigarette storage of the cigarette storage and conveying system for storage. During the shutdown of the rolling machine, the cigarette storage and conveying system will output the cigarettes in the cigarette storage and supply them to the packaging machine to ensure the normal operation of the unit. However, when the cigarette conveying channel of the cigarette storage and conveying system is blocked, the rolling machine continues to operate, causing cigarettes to accumulate at the exit of the rolling machine, which can easily block the rolling machine. Therefore, how to design an anti-blocking device and method to prevent the cigarette conveying channel from being blocked has become a technical problem that technicians in this field urgently need to solve. Summary of the invention

[0003] The purpose of the present invention is to provide a device for preventing a cigarette conveying channel from being blocked, so as to solve the above technical problems in the prior art. The purpose of the present invention is to provide a method for preventing a cigarette conveying channel from being blocked.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] A cigarette conveying channel anti-blocking device comprises a first photoelectric sensor and a second photoelectric sensor, wherein the first photoelectric sensor is arranged at the upper part of the inner rear side plate at the left end of the horizontal section of the cigarette conveying channel, and the second photoelectric sensor is arranged at the upper part of the inner rear side plate at the right end of the horizontal section of the cigarette conveying channel; the first photoelectric sensor is electrically connected to the controller of a cigarette rolling machine, and the second photoelectric sensor is electrically connected to the controller of the cigarette rolling machine and the controller of a cigarette storage and conveying system.

[0006] Preferably, the first photoelectric sensor is connected to the rear side plate via a first bracket, and the second photoelectric sensor is connected to the rear side plate via a second bracket.

[0010] Preferably, the second bracket has the same structure as the first bracket.

[0011] Preferably, the first photoelectric sensor and the second photoelectric sensor are arranged opposite to each other.

[0012] An anti-blocking method based on the above-mentioned anti-blocking device for a cigarette conveying channel comprises:

[0013] When the first photoelectric sensor senses a cigarette, the first photoelectric sensor sends a signal indicating that the cigarettes are piled too high to the controller of the cigarette maker. After receiving the signal indicating that the cigarettes are piled too high, the controller of the cigarette maker controls the running speed of the cigarette maker to decrease.

[0014] As the conveyor belt in the cigarette conveying channel runs, when the second photoelectric sensor senses a cigarette, the second photoelectric sensor sends a signal that the channel is about to be blocked to the controller of the cigarette rolling machine and the controller of the cigarette storage and conveying system, so that the controller of the cigarette rolling machine controls the cigarette rolling machine to stop, and the controller of the cigarette storage and conveying system controls the conveyor belt to stop running.

[0015] The beneficial effects of the present invention are:

[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the solution will be further described in detail below in conjunction with specific embodiments.

[0023] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides an anti-blocking device for a cigarette conveying channel, which includes a first photoelectric sensor 21 and a second photoelectric sensor 31. The first photoelectric sensor 21 is arranged on the upper part of the inner rear side plate at the left end of the horizontal section 12 of the cigarette conveying channel, and the second photoelectric sensor 31 is arranged on the upper part of the inner rear side plate at the right end of the horizontal section of the cigarette conveying channel; the first photoelectric sensor is electrically connected to the controller of the cigarette rolling machine, and the second photoelectric sensor is electrically connected to the controller of the cigarette rolling machine and the controller of the cigarette storage and conveying system.

[0024] The anti-blocking device for the cigarette conveying channel provided in the embodiment of the present invention, when in use, when the first photoelectric sensor 21 senses cigarettes, it indicates that the cigarettes in the horizontal section of the cigarette conveying channel are too piled up, and the first photoelectric sensor 21 sends a signal of excessive cigarette pile-up to the controller of the cigarette rolling machine, so that the running speed of the cigarette rolling machine is reduced, while the conveying speed of the conveyor belt in the cigarette conveying channel and the running speed of the packaging machine remain unchanged, so that the packaging machine can use up some of the excessively piled cigarettes in time, so that the stacking height of the cigarettes is reduced; as the conveyor belt continues to run, when the second photoelectric sensor 31 also senses cigarettes, it indicates that the stacking height of the cigarettes has not dropped below the set limit, and the second photoelectric sensor will send a signal that the channel is about to be blocked to the controller of the cigarette rolling machine and the controller of the cigarette storage and conveying system, so that the cigarette rolling machine is shut down and the conveyor belt stops running, thereby better avoiding the problem of the cigarette conveying channel being blocked due to the continued operation of the conveyor belt and the problem of the cigarette rolling machine being blocked due to the continued operation of the cigarette rolling machine, and thus can play a better role in preventing blockage and preventing the cigarette rolling machine from being blocked.

[0025] Further, the first photoelectric sensor 21 is connected to the rear side plate through a first bracket, and the second photoelectric sensor is connected to the rear side plate through a second bracket, so that the first photoelectric sensor is connected to the rear side plate through the first bracket, and the second photoelectric sensor is connected to the rear side plate through the second bracket.

[0026] Specifically, the first bracket includes a vertical plate 22 and a horizontal plate 23, one end of the vertical plate 22 is vertically connected to one end of the horizontal plate, and the vertical plate and the horizontal plate 23 form an L-shaped structure; the other end of the vertical plate is vertically connected to the rear side plate, and the first photoelectric sensor is arranged on the horizontal plate, so that the structure of the first bracket is relatively simple, and the connection between the first photoelectric sensor and the rear side plate can also be realized.

[0027] Preferably, the vertical plate 22 and the horizontal plate 23 are an integrated structure, so that the strength of the first bracket is greater.

[0028] Specifically, the vertical plate 22 is welded to the rear side plate 13, so that the connection between the first bracket and the rear side plate is relatively firm and reliable. In one embodiment, the vertical plate and the rear side plate can be detachably connected, so as to facilitate the replacement or maintenance of the first bracket.

[0029] Furthermore, the second bracket has the same structure as the first bracket, so that the structure of the second bracket is also relatively simple. It is understandable that the working principle of the first photoelectric sensor 21 and the working principle of the second photoelectric sensor 31 are the same as those of the photoelectric sensors in the prior art, and will not be repeated here.

[0030] Specifically, the first photoelectric sensor 21 and the second photoelectric sensor 31 are arranged opposite to each other, so that the first photoelectric sensor 21 and the second photoelectric sensor 31 are located on the same horizontal line. It can be understood that the vertical position of the first photoelectric sensor and the second photoelectric sensor on the rear side plate 13 is set according to the set limit of the cigarette stacking height; if the cigarette stacking height exceeds the set limit, it is easy to cause blockage at the corner of the cigarette conveying channel, otherwise, it is not easy to be blocked; because the first photoelectric sensor and the second photoelectric sensor are both located above the cigarette, they will not affect the conveying of the cigarette.

[0031] The embodiment of the present invention further provides an anti-blocking method based on the above-mentioned anti-blocking device for a cigarette conveying channel, which comprises:

[0032] When the first photoelectric sensor 21 senses cigarettes, the first photoelectric sensor sends a signal indicating that the cigarettes are piled too high to the controller of the cigarette maker. After receiving the signal indicating that the cigarettes are piled too high, the controller of the cigarette maker controls the running speed of the cigarette maker to decrease.

[0033] As the conveyor belt 14 in the cigarette conveying channel runs, when the second photoelectric sensor senses a cigarette, the second photoelectric sensor sends a channel blockage signal to the controller of the cigarette rolling machine and the controller of the cigarette storage and conveying system, so that the controller of the cigarette rolling machine controls the cigarette rolling machine to stop, and the controller of the cigarette storage and conveying system controls the conveyor belt to stop running. At this time, cigarettes can be supplied to the packaging machine through the cigarette storage 11, so that the packaging machine can operate normally.

[0034] It is understandable that controlling the cigarette cigarette cigar maker to stop can prevent the cigarette cigarette cigar maker from being blocked at the outlet of the cigarette cigarette cigar maker due to the continuous operation of the cigarette cigarette cigar maker, thereby avoiding damage to the cigarette cigarette cigar maker.

[0035] The specific anti-blocking method is as follows: when the first photoelectric sensor 21 does not sense cigarettes, it indicates that the stacking height of cigarettes in the cigarette conveying channel does not exceed the set limit, and the conveyor belt, the cigarette rolling machine, and the packaging machine are operating normally; when the first photoelectric sensor senses cigarettes, it indicates that the stacking height of cigarettes 41 in the cigarette conveying channel exceeds the set limit, and the first photoelectric sensor will send a cigarette stacking too high signal to the controller of the cigarette rolling machine, triggering the cigarette rolling machine to slow down, but the conveyor belt and the packaging machine still maintain the original speed, that is, the speed of the conveyor belt and the packaging machine remains unchanged, so that the packaging machine can use up or consume some of the cigarettes that are stacked too high to reduce the stacking height of the cigarettes;

[0036] As the conveyor belt continues to run, if the second photoelectric sensor 31 also senses cigarettes, indicating that the over-stacked cigarettes run with the conveyor belt 14 to the right end of the horizontal section, the stacking height of the cigarettes 41 still exceeds the set limit. In order to prevent the conveyor belt 14 from continuing to run and causing the cigarettes to be blocked at the corner 15 of the cigarette conveying channel, the second photoelectric sensor will send a channel blocking signal to the controller of the cigarette storage and conveying system, triggering the conveyor belt to stop running. At the same time, in order to prevent the cigarette maker from getting stuck, the cigarette maker will also be triggered to stop.

[0037] If the second photoelectric sensor 31 does not sense any cigarettes, it indicates that when the cigarettes piled up too high run with the conveyor belt to the right end of the horizontal section, the part of the cigarettes above the set limit have been consumed, so that the stacking height of the cigarettes is reduced to below the set limit. At this time, the conveyor belt and the packaging machine still run at the original speed, and the cigarette rolling machine still runs at the speed after the above-mentioned speed reduction. Until the first photoelectric sensor also does not sense any cigarettes, it indicates that the stacking height of the cigarettes at the first photoelectric sensor does not exceed the set limit. At this time, the conveyor belt and the packaging machine still run at the original speed, and the cigarette rolling machine runs at the speed before the speed reduction, that is, the original speed.

[0038] It can be understood that when the first photoelectric sensor and the second photoelectric sensor do not sense cigarettes or foreign objects, the cigarette rolling machine, the cigarette storage and conveying system, and the packaging machine are all operating normally.

[0039] In one embodiment, when the second photoelectric sensor senses a cigarette, the controller of the cigarette storage and conveying system can control the cigarette storage and conveying system to shut down. At this time, the rolling machine and the packaging machine can also shut down. Then the operator can eliminate the risk of blockage in the cigarette conveying channel, such as taking away some cigarettes in the cigarette conveying channel so that the stacking height of the cigarettes is below the set limit, and then restore the normal operation of the rolling machine, the cigarette storage and conveying system, and the packaging machine.

[0040] The present invention can sense excessively stacked cigarettes at an early stage through the first photoelectric sensor located at the left end of the horizontal section, and then reduce the cigarettes transported by the cigarette rolling machine to the cigarette conveying channel by reducing the running speed of the cigarette rolling machine, and keep the speeds of the conveyor belt and the packaging machine unchanged, so that the packaging machine can consume a part of the cigarettes in the cigarette conveying channel to reduce the stacking height of the cigarettes, thereby achieving the purpose of anti-blocking; when the second photoelectric sensor also senses the cigarettes, it triggers the cigarette rolling machine and the cigarette storage and conveying system to shut down. If the second photoelectric sensor does not sense the cigarettes, it does not trigger the cigarette rolling machine and the cigarette storage and conveying system to shut down, thereby better avoiding the premature shutdown from causing a great impact on the production efficiency of the unit.

[0041] The above are only preferred embodiments of the present invention. It should be pointed out that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. Moreover, after reading the contents of the present invention, relevant technical personnel in the field may make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to this application.
