Description

Technical Field

[0001] The invention relates to the field of tobacco packaging, and in particular to a combined cigarette conveying device and a conveying method thereof. Background Art

[0002] At present, the applicant has disclosed a cigarette conveying device in Chinese patent application No. CN201720982908.6, comprising a frame and a vacuum adsorption conveyor belt, a flat belt conveyor belt, and an output device arranged on the frame according to an assembly line, the output device comprising two output conveyor belts arranged on the frame, a conveying device arranged on the frame for conveying items on the output conveyor belts, the conveying device being arranged between the two output conveyor belts, the conveying device comprising a chain mechanism arranged on the frame, a pushing block arranged on the chain mechanism and protruding from the upper surface of the output conveyor belt, the upper surface of the output conveyor belt being lower than the upper surface of the flat belt conveyor belt, and a blocking device for blocking or releasing cigarettes is provided on the frame above the flat belt conveyor belt. Chinese patent application number: CN201821371919.1 discloses a cigarette strip counting and combined output device, including a frame and an input conveyor belt, a combined conveyor device, and an output device arranged on the frame according to an assembly line. The combined conveyor device includes two front and rear combined conveyor belts arranged on the frame and a material-blocking conveyor belt arranged between the two combined conveyor belts, and the material-blocking conveyor belt is provided with at least one baffle. It solves the problem of low working efficiency in the existing counting when the cigarette strips are combined and output. Both solutions combine the delivery of cigarette strips and then output them, so that multiple cigarette strips are formed into a combination, which is convenient for stacking and output in the subsequent packaging process.

[0003] After the cigarettes enter the output conveyor belt from the input conveyor belt, the blocking mechanism is usually used to block the cigarettes on the output conveyor belt, so as to wait for the required number of combinations to be reached. When the number is reached, the pressing mechanism is usually used to block the cigarettes to prevent the cigarettes on the input conveyor belt from entering. Then the pushing mechanism is used to push out the combination of cigarettes after the number is reached, completing a combination of cigarettes.

[0004] Since the combined conveying of cigarette strips requires a waiting time, that is, the time from when the material blocking starts after the cigarette strips are output to when the number is reached, the setting of the waiting time is the same when the combined number of cigarette strips is small and when the combined number of cigarette strips is large. In this way, when the combined number of cigarette strips is small, there will be an idle waiting time. For example, if the original maximum combined number of cigarette strips is set to 5, then the waiting time is set based on 5, set to 0.2 seconds / strip, and the waiting time is 1 second. If the combined number of cigarette strips this time is 2, then the idle waiting time is 0.6 seconds. Although the combined conveying of cigarette strips belongs to high-speed packaging, that is to say, the speed is very fast, the waiting time is actually not greater than 1 second, but for the high-speed packaging process, if it can be increased by 20%, it is also a huge improvement. How to solve the problem of this idle waiting time is also the research direction of the applicant. Summary of the invention

[0005] Therefore, in view of the above problems, the present invention proposes a combined cigarette conveying device, which solves the technical problem of idle waiting time in the existing combined cigarette conveying, and accordingly proposes a combined cigarette conveying method.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solutions: a combined cigarette conveying device, comprising a frame and an input conveyor belt and an output device arranged on the frame according to an assembly line, the output device comprising two output conveyor belts arranged on the frame at intervals, a sending device arranged on the frame for sending articles on the output conveyor belts, the sending device being arranged between the two output conveyor belts, the sending device comprising an annular conveying mechanism arranged on the frame, a pushing block arranged on the annular conveying mechanism and protruding from the upper surface of the output conveyor belt, a material blocking mechanism is arranged on the frame at the front end of the sending device and between the two output conveyor belts, the material blocking mechanism comprises a linear drive mechanism arranged on the frame, a lifting drive mechanism arranged on the linear drive mechanism, and a material blocking member arranged on the lifting drive mechanism, the frame is provided with a sensing device for detecting the number of cigarettes blocked by the front end of the material blocking member, and the material blocking member can be higher or lower than the surface of the output conveyor belt when driven by the lifting drive mechanism.

[0007] Furthermore, the sensing device is a pressure sensing device, which is arranged on the material blocking member.

[0008] Furthermore, a first infrared sensing device for sensing cigarette strips is provided on the frame between the material shifting device and the material blocking mechanism.

[0009] Furthermore, a second infrared sensing device for sensing cigarette strips is provided on the frame behind the pressing mechanism.

[0010] Furthermore, a side baffle mechanism is provided on the frame on both sides of the output device, and the side baffle mechanism includes more than two mounting columns adjustably arranged on the frame and a circular baffle rod arranged on each mounting column. The mounting columns can be close to or away from the output device by bolt locking.

[0011] Furthermore, a material pressing mechanism for limiting the transportation of cigarette strips is provided on the frame at the output end of the input conveyor belt or the input end of the output conveyor belt.

[0012] A combined cigarette conveying method based on the same inventive concept comprises the following steps:

[0013] In the first step, the system gives the linear drive mechanism a command of the number of cigarette cartons, thereby realizing the displacement of the material blocking member. When the number of cigarette cartons decreases, the material blocking member moves toward the input conveyor belt. When the number of cigarette cartons increases, the material blocking member moves toward the output direction of the output conveyor belt, and the material blocking member rises and is higher than the surface of the output conveyor belt.

[0014] In the second step, the input conveyor belt feeds cigarettes to the output conveyor belt, and the sensing device determines the cigarettes blocked by the blocking member. When the number of cigarettes given by the system is met, the pressing mechanism presses down to block the cigarettes that are about to enter the output conveyor belt;

[0015] In the third step, the material blocking member descends, allowing the cigarette strips to enter the workstation of the material-dispensing device along the output conveyor belt. After entering, the material is dispensed and discharged.

[0016] Furthermore, in the first step, when the number of cigarette cartons decreases, the smoke blocking frequency is reduced, and when the number of cigarette cartons increases, the smoke blocking frequency is increased to improve the output efficiency of cigarette cartons.

[0017] Furthermore, the frequency of smoke blocking is raised or lowered according to the number of cigarette cartons given by the system. The time it takes for a cigarette carton to move one station on the output conveyor belt is set to T, the number of cigarette cartons given by the system this time is set to N, and the time it takes for the material blocking piece to rise again after it descends is N*T*1.1~N*T*1.2.

[0018] A combined cigarette conveying device based on the same inventive concept comprises a frame and an input conveyor belt and an output device arranged on the frame according to an assembly line, the output device comprising an output conveyor belt arranged on the frame, two feeding devices arranged on the frame for feeding articles on the output conveyor belt, the two feeding devices being arranged on both sides of the output conveyor belt, the feeding device comprising an annular conveying mechanism arranged on the frame, a pushing block arranged on the annular conveying mechanism and protruding from the upper surface of the output conveyor belt, characterized in that a material blocking mechanism is provided on the frame at the front end of each feeding device and at both sides of the output conveyor belt, the material blocking mechanism comprises a linear drive mechanism arranged on the frame, a lifting drive mechanism arranged on the linear drive mechanism, and a material blocking member arranged on the lifting drive mechanism, the frame is provided with a sensing device for detecting the number of cigarettes blocked by the front end of the material blocking member, and the material blocking member can be higher or lower than the surface of the output conveyor belt under the drive of the lifting drive mechanism.

[0019] By adopting the above technical solution, the beneficial effects of the present invention are:

[0020] 1. This scheme can realize the back and forth movement of the material blocking member along the output direction of the output conveyor belt through a linear drive mechanism, so as to realize the adjustment of the material blocking position and the adjustment of the material blocking quantity. The linear drive mechanism can adopt an electric cylinder or other mechanism capable of realizing linear drive, such as a cylinder, an oil cylinder, a screw mechanism, a synchronous belt mechanism, etc. The lifting drive mechanism can realize the rise and fall of the material blocking member, so as to realize the normal transportation of the material blocking member and the output conveyor belt. The sensing device can be a counting system or a high-speed camera. This scheme adopts a pressure sensing device, which can realize the sensing of the pressure of the blocked cigarette strips and realize the accurate determination of the number of blocked cigarette strips, thereby improving the stability of the device. In this process, the counting system can also be used to accurately determine the number of cigarette strips input. However, if the counting system is relied on alone, counting errors may occur due to the high-speed state, resulting in unstable operation. The material blocking mechanism realizes the elimination of the idle waiting time, and the intuitive reaction is also the increase of its movement frequency. The corresponding pressing mechanism will also cooperate with the material blocking mechanism, and the intuitive reaction is also the increase of its movement frequency. During actual operation, a combined output device with changing motion frequency will be formed, which is commonly known as variable frequency transmission.

[0021] 2. The first infrared sensing device belongs to the counting system and is used to cooperate with the pressure sensing device to achieve material blocking. It can also detect whether there is a cigarette strip at the vertical position. If there is a cigarette strip, the material blocking mechanism will run a cigarette strip position in the conveying direction of the output conveyor belt under the drive of the linear drive mechanism, and repeat this process to achieve the purpose of effective error correction.

[0022] 3. The second infrared sensing device belongs to the detection system, which is used to detect the cigarette carton between the material blocking mechanism and the conveying device, and detect whether there is a cigarette carton. When the waiting time comes, that is, when no cigarette carton passes by, the conveying device realizes the material output.

[0023] 4. The setting of the side baffle mechanism can be easily adjusted to achieve effective lateral protection.

[0024] 5. This combined cigarette conveying method can effectively eliminate the controlled waiting time by adding a material blocking mechanism, thereby effectively improving the conveying efficiency of cigarettes, and can effectively improve the stability of conveying by setting up a sensing device to achieve accuracy during combined conveying.

[0025] 6. Moreover, on the basis of eliminating the idle waiting time, the efficiency can be further improved, that is, the frequency of cigarette blocking can be increased, that is, the frequency of falling and rising of the material blocking member can be increased. In addition to the waiting time, there is also an output time, that is, the time waiting for the cigarette carton to leave the material blocking mechanism, and the time waiting for the cigarette carton to enter the material diverting device, which can effectively avoid interference. In the existing settings, the output time is a fixed value like the waiting time, and the output time and the waiting time will also be idle. For example, after the material blocking member descends, if there are 5 cigarette carton, the material blocking member needs to wait for the delivery time of 5 cigarette carton before it can rise. If 5 cigarette carton is set as the maximum combination, even if it is 3 cigarette carton, the material blocking member also needs to wait for the delivery time of 5 cigarette carton before it can rise, thus forming an idle output time. The increase in the frequency of smoke blocking means that after the sensing device confirms the number of cigarette strips given by the system, the blocking piece descends, and the time for the cigarette strips to move one station on the output conveyor belt is set to T, and the number of cigarette strips given by the system this time is set to N. The time for the blocking piece to rise again after it descends is N*T*1.1~N*T*1.2, and the time for the blocking piece to rise again after it descends is N*T*1.1~N*T*1.2. In this way, the change in the frequency of smoke blocking can be effectively achieved, thereby effectively eliminating idle output time, thereby effectively improving work efficiency. When the number of cigarette strips is significantly reduced, since the conveying pressure of the system is not large, a certain amount of idle time is conducive to the rest of the equipment, thereby effectively ensuring the good operation of the equipment. Even when there is a gap in the incoming material, the machine can be temporarily shut down to wait for the entry of cigarette strips.

[0026] 7. This solution adopts an output conveyor belt arranged in the middle, and material blocking mechanisms and feeding devices are arranged on both sides, so that the purpose of universal material blocking and feeding can be achieved, forming a combined output device with variable motion frequency, which is commonly known as variable frequency conveying.

The material pressing mechanism includes a material pressing cylinder 51 provided on the frame 1 and a material pressing plate 52 provided on the material pressing cylinder 51. A guide feed plate 53 is also provided on the frame 1 at the front end of the material pressing cylinder 51. The material pressing mechanism in this scheme may not be provided, and the input of cigarette strips may be limited by pausing the input conveyor belt, or the input conveyor belt may be set as an adsorption conveyor belt to limit the input of cigarette strips by adsorption, or other material blocking structures such as blocking rods may be used to block cigarette strips.

The material blocking member 63 is provided with a pressure sensing device 64 for measuring the pressure of the blocked cigarette strips. The pressure sensing device 64 is a conventional pressure sensor, which is a well-known component and is not described in detail here. The material blocking member 63 can be higher than the surface of the output conveyor belt 3 or lower than the surface of the output conveyor belt 3 when driven by the lifting drive mechanism. In this solution, the linear drive mechanism 61 is an electric cylinder, and the lifting drive mechanism 62 is a pneumatic cylinder.

[0035] A first infrared sensing device 71 for sensing cigarette strips is provided on the frame 1 between the material shifting device 4 and the material blocking mechanism.

[0036] The beneficial effects of the present invention are:

[0037] 1. This scheme can realize the back and forth movement of the material blocking member along the output direction of the output conveyor belt through a linear drive mechanism, so as to realize the adjustment of the material blocking position and the adjustment of the material blocking quantity. The linear drive mechanism can adopt an electric cylinder or other mechanism capable of realizing linear drive, such as a cylinder, an oil cylinder, a screw mechanism, a synchronous belt mechanism, etc. The lifting drive mechanism can realize the rise and fall of the material blocking member, so as to realize the normal transportation of the material blocking member and the output conveyor belt. The pressure sensing device can sense the pressure of the blocked cigarette strips and accurately determine the number of blocked cigarette strips, thereby improving the stability of the device. In this process, the counting system can also be used to accurately determine the number of cigarette strips input. However, if the counting system is relied on alone, it is easy to make counting errors due to the high-speed state, resulting in unstable operation. The material blocking mechanism eliminates the idle waiting time, and the intuitive reaction is also the increase of its movement frequency. The corresponding material pressing mechanism will also cooperate with the material blocking mechanism, and the intuitive reaction is also the increase of its movement frequency. In actual operation, a combined output device with a changing movement frequency will be formed, which is commonly known as variable frequency transmission.

[0038] 2. The first infrared sensing device belongs to the counting system and is used to cooperate with the pressure sensing device to achieve material blocking. It can also detect whether there is a cigarette strip at the vertical position. If there is a cigarette strip, the material blocking mechanism will run a cigarette strip position in the conveying direction of the output conveyor belt under the drive of the linear drive mechanism, and repeat this process to achieve the purpose of effective error correction.

[0039] 3. The second infrared sensing device belongs to the detection system, which is used to detect the cigarette carton between the material blocking mechanism and the conveying device, and detect whether there is a cigarette carton. When the waiting time comes, that is, when no cigarette carton passes by, the conveying device realizes the material output.

[0040] 4. The setting of the side baffle mechanism can be easily adjusted to achieve effective lateral protection.

[0041] A method for conveying combined cigarette cartons based on the combined cigarette cartons output device comprises the following steps:

[0042] In the first step, the system gives the linear drive mechanism a command of the number of cigarette cartons, thereby realizing the displacement of the material blocking member. When the number of cigarette cartons decreases, the material blocking member moves toward the input conveyor belt, and when the number of cigarette cartons increases, the material blocking member moves toward the output direction of the output conveyor belt, and the material blocking member rises and is higher than the surface of the output conveyor belt. When the number of cigarette cartons decreases, the frequency of cigarette blocking increases, and when the number of cigarette cartons increases, the frequency of cigarette blocking decreases, so as to improve the output efficiency of cigarette cartons;

[0043] In the second step, the input conveyor belt feeds cigarettes to the output conveyor belt, and the sensing device determines the cigarettes blocked by the blocking member. When the number of cigarettes given by the system is met, the pressing mechanism presses down to block the cigarettes that are about to enter the output conveyor belt;

[0044] In the third step, the material blocking member descends, allowing the cigarette strips to enter the workstation of the material-dispensing device along the output conveyor belt. After entering, the material is dispensed and discharged.

[0045] The frequency of smoke blocking is set according to the number of cigarettes given by the system. The time for a cigarette to move one station on the output conveyor is set to T, the number of cigarettes given by the system is set to N, and the time for the blocking member to rise again after it falls is N*T*1.1~N*T*1.2. Similarly, the pressing mechanism moves basically synchronously with the blocking member. When the blocking member rises, the pressing mechanism rises. When the blocking member falls, the pressing mechanism falls.

[0046] The combined conveying method of cigarette cartons can effectively eliminate the controlled waiting time by adding a material blocking mechanism, thereby effectively improving the conveying efficiency of cigarette cartons, and can effectively improve the stability of conveying by providing a sensing device to achieve accuracy during combined conveying.

[0047] Moreover, on the basis of eliminating the idle waiting time, the efficiency can be further improved, that is, the frequency of cigarette blocking can be increased, that is, the frequency of falling and rising of the material blocking member can be increased. In addition to the waiting time, there is also an output time, that is, the time waiting for the cigarette carton to leave the material blocking mechanism, and the time waiting for the cigarette carton to enter the material diverting device, which can effectively avoid interference. In the existing settings, the output time is a fixed value like the waiting time, and the output time and the waiting time will also be idle. For example, after the material blocking member descends, if there are 5 cigarette carton, the material blocking member needs to wait for the delivery time of 5 cigarette carton before it can rise. If 5 cigarette carton is set as the maximum combination, even if it is 3 cigarette carton, the material blocking member also needs to wait for the delivery time of 5 cigarette carton before it can rise, thus forming an idle output time. The increase in the smoke blocking frequency means that after the sensing device confirms the number of cigarettes given by the system, the blocking piece descends, and the time for the cigarette to move one station on the output conveyor belt is set to T, and the number of cigarettes given by the system this time is set to N. The time for the blocking piece to rise again after descending is N*T*1.1~N*T*1.2, and the time for the blocking piece to rise again after descending is N*T*1.1~N*T*1.2. In this way, the change in the smoke blocking frequency can be effectively realized, thereby effectively eliminating the idle output time and effectively improving work efficiency.

[0048] In this method, the pressure sensing device actually plays a relatively important role. Due to the high-speed conveying process and the variable frequency state, it is easy to make mistakes in judgment when using infrared counting and high-speed camera counting, resulting in errors in the output process. At this time, a physical measurement is required, which is also difficult. Using a pressure sensing device to sense the number of cigarettes through pressure is a relatively safe solution. And it can be combined with a counting system, such as the first infrared sensing device, to form a more accurate number sensing, so that the entire conveying method can be effectively implemented.

[0049] In terms of eliminating idle output time, the second infrared sensing device also plays a similar role as the first infrared sensing device. And the delivery device can also follow the frequency conversion to achieve the delivery and output of the cigarette carton. When the second infrared sensing device senses that the cigarette carton has entered or no longer enters, the delivery device operates and uses the push block to deliver the cigarette carton.

[0050] Refer to Figure 4, the second embodiment provides a combined cigarette conveying device based on the same inventive concept, including a frame and an input conveyor belt and an output device arranged on the frame according to the assembly line, the output device including an output conveyor belt arranged on the frame, two feeding devices arranged on the frame for feeding articles on the output conveyor belt, the two feeding devices are arranged on both sides of the output conveyor belt, the feeding device includes an annular conveying mechanism arranged on the frame, a pushing block arranged on the annular conveying mechanism and protruding from the upper surface of the output conveyor belt, a pressing mechanism for limiting the feeding of cigarettes is provided on the frame at the output end of the input conveyor belt or the input end of the output conveyor belt, a material blocking mechanism is provided on the frame at the front end of each feeding device and on both sides of the output conveyor belt, the material blocking mechanism includes a linear driving mechanism arranged on the frame, a lifting driving mechanism arranged on the linear driving mechanism, and a material blocking member arranged on the lifting driving mechanism, the material blocking member is provided with a pressure sensing device for measuring the pressure of the blocked cigarettes, and the material blocking member can be higher or lower than the surface of the output conveyor belt when driven by the lifting driving mechanism.

[0051] This solution adopts an output conveyor belt 3' in the middle, and a material blocking mechanism 6' and a feeding device 4' are set on both sides, so that the purpose of general material blocking and feeding can be achieved, forming a combined output device with variable motion frequency, which is usually called variable frequency transmission.

If the length is longer, it is more advantageous.
