Description

Technical Field

[0001] The utility model relates to the technical field of cigarette sorting and conveying, and particularly relates to a conveying device for assisting cigarette sorting. Background Technique

[0002] Cigarette sorting machines are relatively popular cigarette sorting equipment in China at present. In commercial tobacco distribution centers, cigarettes of different specifications are cached in each cigarette sorting channel of the cigarette sorting machine. According to different customer requirements, the cigarette pickers operate the cigarette sorting machine to take out cigarettes of different specifications and quantities from each cigarette sorting channel, and then convey them to the packing line through the conveying device for film covering and packaging.

[0003] At present, the existing conveying devices are generally belt conveyors or plate conveyors, which are arranged in a cross manner with the cigarette sorting machine, that is, the conveying device is installed on one side of the output port of the cigarette sorting machine, and the conveying direction of the conveying device is perpendicular to the cigarette output direction of the cigarette sorting machine, so as to ensure that the cigarettes in each cigarette sorting channel on the cigarette sorting machine can enter the conveying device and remain in a horizontal state on the conveying device, so as to be easily conveyed to the packing line for film covering and packaging. For example, the cigarette confirmation control device in the cigarette sorting system disclosed in the authorized publication number CN203392306U has a cigarette conveyor belt installed on one side of the sorting rack, and the conveying direction of the cigarette conveyor belt is perpendicular to the cigarette output direction of the sorting rack. After the cigarettes in the sorting rack are output, they enter the cigarette conveyor belt horizontally and are conveyed through the cigarette conveyor belt.

[0004] However, this conveying method also has certain drawbacks. When the cigarettes are pushed out by the sorting rack, the cigarettes will enter the conveying device under the action of inertial force. Due to the differences in the packaging specifications and weights of cigarettes of different brands, and the different stacking quantities of cigarettes in each cigarette sorting channel, the cigarettes with more stacking quantities will form a certain extrusion force downward, resulting in different impact forces when the cigarettes enter the conveying device. When the impact force of the cigarettes is too large, they will collide with the edge of the conveying device and rebound, easily causing the cigarettes to be placed in an incorrect position and skewed after falling on the conveying device, resulting in uneven stacking of the cigarettes in the subsequent packing and film covering processes. Summary of the Utility Model

[0005] In view of this, it is necessary to provide a conveying device for assisting cigarette sorting to solve the technical problem that the cigarettes collide and rebound with the edge of the conveying device in the prior art, resulting in incorrect placement of the cigarettes on the conveying device.

[0010] Preferably, the buffer stop curtain is made of canvas or flexible rubber sheet.

[0011] Preferably, the side wall of the buffer stop curtain facing the cigarette carton sorting machine is a smooth surface.

[0012] Preferably, a secondary conveying device is further provided on the side wall of the conveying rack close to the cigarette sorting machine. The secondary conveying device is vertically arranged, and the conveying surface of the secondary conveying device is perpendicular to the conveying surface of the main conveyor belt and faces the buffer stop curtain. The secondary conveying device and the buffer stop curtain form a channel for auxiliary cigarette conveying on both sides of the conveying surface of the main conveyor belt, and operate synchronously, in the same direction, and at the same speed as the main conveyor belt to assist in conveying the cigarettes falling onto the main conveyor belt.

Specific embodiments

[0020] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following will briefly introduce the drawings required for the embodiments. Obviously, the drawings in the following description are some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained based on these drawings.

[0021] Please refer to Figure 1 and Figure 2 , the embodiments of the present invention provide a conveying device for assisting cigarette-strip sorting. The conveying device for assisting cigarette-strip sorting is arranged at the output port of the cigarette-strip sorting channel 11 of the cigarette-strip sorting machine 10. The cigarette-strip sorting machine 10 is a vertical cigarette-strip sorting machine, and a plurality of vertically arranged cigarette-strip sorting channels 11 are arranged in parallel on its body. A pushing mechanism 12 is arranged at the lower end of each cigarette-strip sorting channel 11. The pushing mechanism 12 is used to push the cigarette strips out of the cigarette-strip sorting channel 11. The conveying device for assisting cigarette-strip sorting is used to receive and assist in transporting the cigarette strips output from the cigarette-strip sorting channel 11. The conveying device for assisting cigarette-strip sorting includes a main conveying device 20 and a buffer stopper 30. The main conveying device 20 is arranged in parallel on one side of the cigarette-strip sorting machine 10 at the output port of the cigarette-strip sorting channel 11. The conveying direction of the main conveying device 20 is perpendicular to the output direction of the cigarette-strip sorting channel 11, and the conveying surface of the main conveying device 20 is lower than the output port of the cigarette-strip sorting channel 11. The buffer stopper 30 is arranged in parallel on the side of the main conveying device 20 away from the cigarette-strip sorting machine 10 and is located above the inner side of the conveying surface of the main conveying device 20 and is directly opposite to the output port of the cigarette-strip sorting channel 11 of the cigarette-strip sorting machine 10 to stop the cigarette strips output from the cigarette-strip sorting channel 11 and make the cigarette strips stably fall onto the conveying surface of the main conveying device 20.

[0022] Specifically, the main conveyor device 20 includes a conveyor frame 21, a main conveyor belt 22, and a main drive motor 23. The conveyor frame 21 is arranged in parallel on one side of the cigarette sorting machine 10 at the output port of the cigarette sorting channel 11. At both ends of the conveyor frame 21, main drive rollers 24 are arranged in parallel. The main conveyor belt 22 is sleeved annularly on the two main drive rollers 24. The main drive motor 23 is arranged at one end of the conveyor frame 21 and is axially connected to one of the main drive rollers 24 to drive the main conveyor belt 22 to run along the conveyor frame 21. The running direction of the main conveyor belt 22 is perpendicular to the output direction of the cigarette sorting channel 11, and the conveying surface of the main conveyor belt 22 is lower than the output port of the cigarette sorting channel 11. The buffer stop member 30 includes a support frame 31 and a buffer stop curtain 32. The support frame 31 is arranged on the edge of the conveyor frame 21 on the side away from the cigarette sorting machine 10, parallel to the conveyor frame 21. The lower end of the support frame 31 is fixedly connected to the conveyor frame 21, and the upper end of the support frame 31 extends above the conveyor frame 21, higher than the output port of the cigarette sorting channel 11. The buffer stop curtain 32 is arranged at the upper end of the support frame 31. The upper end of the support frame 31 bends towards the side opposite to the conveyor frame 21, that is, the direction of the cigarette sorting machine 10. The upper end of the buffer stop curtain 32 is fixedly installed with the upper end of the support frame 31. The lower end of the buffer stop curtain 32 is a free end. The buffer stop curtain 32 is suspended above the inner side of the conveying surface of the main conveyor belt 22 through the support frame 31. This free end is close to the conveying surface of the main conveyor belt 22, does not contact the conveying surface of the main conveyor belt 22, and can swing freely. The side wall of the buffer stop curtain 32 facing the cigarette sorting machine 10 is directly opposite to the output port of the cigarette sorting channel 11 of the cigarette sorting machine 10. The buffer stop curtain 32 is made of canvas or flexible rubber plate. During the sorting process, when the cigarette is pushed out from the cigarette sorting channel 11 by the pushing mechanism 12, it will hit the buffer stop curtain 32. After the buffer stop curtain 32 is hit by the cigarette, its free end will swing adaptively to buffer the impact force of the cigarette. After the cigarette hits the buffer stop curtain 32, it falls onto the main conveyor belt 22 under the action of gravity. The buffer stop curtain 32 has the function of absorbing energy. By using the buffer stop curtain 32 to stop the cigarettes output from the cigarette sorting channel 11, it can prevent the cigarettes from rebounding, and thus enable the cigarettes to stably fall onto the conveying surface of the main conveyor belt 22. The side wall of the buffer stop curtain 32 facing the cigarette sorting machine 10 is a smooth surface, and the friction coefficient with the cigarette is small.

[0023] Please refer to Figure 1 and Figure 3, Further, a secondary conveyor device 40 is also provided on the side wall of the conveyor frame 21 close to the side of the cigarette sorting machine 10. The secondary conveyor device 40 includes a secondary conveyor belt 41, secondary drive rollers 42 and a secondary drive motor 43. There are two secondary drive rollers 42, which are longitudinally arranged on the side wall of the conveyor frame 21 facing the cigarette sorting machine 10, and are respectively close to both ends of the conveyor frame 21. The secondary conveyor belt 41 is annularly sleeved on the two secondary drive rollers 42. The conveying surface of the secondary conveyor belt 41 is in a vertical state, perpendicular to the conveying surface of the main conveyor belt 22, close to the edge of the main conveyor belt 22, and higher than the conveying surface of the main conveyor belt 22, and is directly opposite to the buffer stop curtain 32. The width between the secondary conveyor belt 41 and the buffer stop curtain 32 is greater than the length of the cigarette. The secondary drive motor 43 is arranged on the conveyor frame 21 and is axially connected to one of the secondary drive rollers 42. The secondary drive motor 43 axially drives the secondary conveyor belt 41 through the secondary drive roller 42, so that the secondary conveyor belt 41 and the main conveyor belt 22 operate synchronously, in the same direction and at the same speed, so as to assist in conveying the cigarettes falling on the main conveyor belt 22. The secondary conveyor belt 41 plays a role of stopping and synchronous conveying at the edge of the main conveyor belt 22. When the main conveyor belt 22 conveys the cigarettes, if the cigarettes come into contact with the side wall of the conveyor frame 21 on the side of the main conveyor belt 22, the side wall of the conveyor frame 21 will form a frictional force on the cigarettes, which will cause the cigarettes to skew on the main conveyor belt 22. By setting the secondary conveyor belt 41 as the side wall of the conveyor frame 21, the secondary conveyor belt 41 and the main conveyor belt 22 operate synchronously, in the same direction and at the same speed. When the cigarettes come into contact with the secondary conveyor belt 41, the secondary conveyor belt 41 can play a role in assisting synchronous conveying of the cigarettes, enabling the cigarettes to be stably conveyed on the main conveyor belt 22 and avoiding the situation of the cigarettes skewing during the conveying process.

[0024] The conveying device for assisting cigarette sorting utilizes a buffer stop member 30 provided on one side of the conveyor frame 21 facing the output port of the cigarette sorting channel 11. During the output process of cigarette sorting, the buffer stop member 30 can buffer the impact force of the cigarettes, avoiding the hard contact between the cigarettes and the side wall of the main conveyor device 20 when entering the main conveyor device 20 and causing the rebound phenomenon. The impact force of the cigarettes is buffered by the flexible acting force of the buffer stop member 30 to prevent the cigarettes from rebounding, and then the cigarettes can fall onto the main conveyor device 20 correctly and stably, avoiding the situation of the cigarettes skewing due to hard contact and rebound during the process of entering the main conveyor device 20, and thus solving the problem of uneven stacking of cigarettes in the subsequent packing and film covering processes.

[0025] The above-disclosed are only the preferred embodiments of the present invention. Of course, the scope of the rights of the present invention cannot be limited thereby. Those of ordinary skill in the art can understand all or part of the processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
