Description

Technical Field

[0001] The present application relates to the technical field of cigarette pack conveying, and in particular to a cigarette pack stopping device for a conveying channel of an HNB packaging device. Background Art

[0002] During the production process, cigarette factories need to use packaging equipment to package cigarette packs. At present, HNB packaging equipment is usually used for packaging heat-not-burn cigarettes. HNB packaging equipment is a transformation packaging equipment. The packaging equipment was originally used for packaging equipment in the paper towel, food and other industries. After the transformation to the packaging of heat-not-burn cigarette products, there are certain connection problems. The HNB packaging equipment includes a small box liner packaging machine and a two-in-one label paper packaging machine. A longitudinal conveyor belt and a transverse conveyor belt are arranged between the small box liner packaging machine and the two-in-one label paper packaging machine. The cigarette packs processed by the small box liner packaging machine are conveyed to the longitudinal conveyor belt, and the longitudinal conveyor belt is used for packaging heat-not-burn cigarettes. A first cylinder is provided at the end of the conveyor belt, which pushes the cigarette packs on the longitudinal conveyor belt one by one onto the transverse conveyor belt. A second cylinder is provided along the transverse conveyor belt, which pushes the cigarette packs on the transverse conveyor belt in groups of two to the two-in-one trademark paper packaging machine for processing. It was found during the production process that when the two-in-one trademark paper packaging machine fails, the second cylinder will stop pushing cigarette packs to the two-in-one trademark paper packaging machine, while the intersection of the longitudinal and transverse conveyor belts and the upstream continue to work, which may easily cause extrusion and deformation of the cigarette packs. If the intersection and the upstream are also shut down, it will affect the continuity of the main machine production, which is not conducive to the control and improvement of the production progress.

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0027] like Figure 1-Figure 3As shown, the embodiment of the present application provides a cigarette pack stopping device for a conveying channel of an HNB packaging device, which is applied to the packaging process of cigarette packs. The HNB packaging device performs a packaging process for heat-not-burn cigarette products. The HNB packaging device includes a small box liner packaging machine and a two-in-one label paper packaging machine, and the cigarette packs are conveyed between the small box liner packaging machine and the two-in-one label paper packaging machine through two conveyor belts. The two conveyor belts are perpendicular to each other, and the end of the front conveyor belt is near the rear conveyor belt. A first pushing cylinder is arranged on the rear conveyor belt near the end of the front conveyor belt. The first pushing cylinder pushes the cigarette packs on the front conveyor belt onto the rear conveyor belt. A second pushing cylinder is also arranged on the rear conveyor belt. The second pushing cylinder pushes the cigarette packs on the rear conveyor belt onto the two-in-one label paper packaging machine. The packaging process is carried out at the label paper packaging machine. During this process, if a fault occurs at the two-in-one label paper packaging machine, the second push cylinder will stop pushing the cigarette packs on the rear conveyor belt to the two-in-one label paper packaging machine, while the small box liner packaging machine will continue to convey the cigarette packs to the front conveyor belt, and the first push cylinder will also continue to push the cigarette packs to the rear conveyor belt, so the cigarette packs will be piled up and squeezed. If the operation of the first push cylinder and the small box liner packaging machine is stopped, the upstream equipment will also be shut down. In this way, the continuity of the main machine production will be affected, which is not conducive to the control and improvement of the production progress and affects the production efficiency. The stopping device of the present application is intended to avoid the shutdown of the entire HNB packaging equipment when a fault occurs in the two-in-one label paper packaging machine, so as to improve the overall effective operating efficiency.

[0028] The cigarette pack stopping device for the conveying channel of the HNB packaging equipment comprises a first conveying channel 100, a second conveying channel 200, a limiting component 300, a first monitoring device 41, a second monitoring device 42, a rejecting component 500 and a controller. The first conveying channel 100 conveys cigarette packs along a first direction. The first conveying channel 100 can be a first conveyor belt. The first conveying channel 100 has a feeding end and a discharging end. The small box liner packaging machine transfers the processed cigarette packs to the first conveying channel 100 via the feeding end of the first conveying channel 100. The second conveying channel 200 conveys the cigarette packs along the second direction. The discharging end of the first conveying channel 100 is arranged close to the second conveying channel 200 so that the cigarette packs on the first conveying channel 100 are transferred to the first conveying channel 100 via the feeding end of the first conveying channel 100. The discharge end of the channel 100 is transferred to the second conveying channel 200. The limiting component 300 is arranged at the discharge end of the first conveying channel 100, and is used to block the cigarette package on the first conveying channel 100 from transferring to the second conveying channel 200. The limiting component 300 can block the cigarette package from transferring from the first conveying channel 100 to the second conveying channel 200. The limiting component 300 can also release the cigarette package so that the cigarette package on the first conveying channel 100 is smoothly transferred to the second conveying channel 200. The first monitoring device 41 is arranged at the second conveying channel 200. The first monitoring device 41 is used to monitor the residence time of the cigarette package on the second conveying channel 200. The second monitoring device 42 is arranged at the first conveying channel 100. The second monitoring device 42 is used to monitor The residence time of the cigarette pack on the first conveying channel 100 is measured, and the rejection component 500 is arranged at the first conveying channel 100. The rejection component 500 is used to reject the cigarette pack on the first conveying channel 100. The first monitoring device 41 is electrically connected to the controller, the second monitoring device 42 is electrically connected to the controller, the limit component 300 is electrically connected to the controller, and the rejection component 500 is electrically connected to the controller. In the working state, when the first monitoring device 41 detects that the residence time of the cigarette pack on the second conveying channel 200 exceeds the first preset value, the limit component 300 blocks the cigarette pack on the first conveying channel 100 from being conveyed to the second conveying channel 200. At this time, when the second monitoring device 42 detects that the residence time of the cigarette pack on the first conveying channel 100 exceeds the second preset value, the limit component 300 blocks the cigarette pack on the first conveying channel 100 from being conveyed to the second conveying channel 200. When the value is reached, the rejecting component 500 rejects the cigarette pack at the corresponding position from the first conveying channel 100, that is, the cigarette pack packed by the small box liner packaging machine is first conveyed to the first conveying channel 100, and then the cigarette pack is transferred from the first conveying channel 100 to the second conveying channel 200, and then the cigarette pack is transferred from the second conveying channel 200 to the two-in-one trademark paper packaging machine. When the two-in-one packaging machine fails, the second pushing cylinder stops pushing the cigarette pack to the two-in-one trademark paper packaging machine, while the small box liner packaging machine continues to convey the cigarette pack to the first conveying channel 100, and the first pushing cylinder continues to push the cigarette pack on the first conveying channel 100 to the second conveying channel 200, so that the cigarette packs are continuously accumulated on the second conveying channel 200. When there are too many cigarette packs,The cigarette packs on the second conveying channel 200 will stop running. At this time, when the first monitoring device 41 detects that the residence time of the cigarette packs on the second conveying channel 200 exceeds two seconds, the first monitoring device 41 transmits a signal to the controller, which controls the limit component 300 to operate. The limit component 300 blocks the cigarette packs at the end of the first conveying channel 100 to prevent the first conveying channel 100 from continuing to convey the cigarette packs to the second conveying channel 200, thereby avoiding the accumulation of cigarette packs on the second conveying channel 200. Then, under the action of the limit component 300, the cigarette packs continue to accumulate on the first conveying channel 100, and the number of blocked cigarette packs gradually increases. When the range of the cigarette packs that stop moving gradually expands, when the cigarette packs that stop moving gradually expand, When the moving cigarette packs extend to the second monitoring device 42 and the second monitoring device 42 detects that the cigarette packs stay there for more than three seconds, the second monitoring device 42 transmits a signal to the controller, and the controller starts the rejection component 500. Along the conveying direction of the first conveying channel 100, the rejection component 500 is located upstream of the second monitoring device 42. The rejection component 500 rejects the cigarette packs that are continuously conveyed upstream from the first conveying channel 100 and collects them in a centralized manner. Therefore, the cigarette packs are stopped and the accumulation of cigarette packs on the first conveying channel 100 and the second conveying channel 200 can be prevented. The shutdown of other parts of the equipment can also be avoided, which is conducive to maintaining the overall effective operation rate and improving the overall production progress.

[0029] Preferably, the limiting assembly 300 includes a mounting frame, on which a pressing plate 301 is movably provided. When the pressing plate 301 is movable, it can press the cigarette packs on the first conveying channel 100 or release the cigarette packs on the first conveying channel 100. In this embodiment, a stop cylinder 302 is provided on the mounting frame, and the pressing plate 301 is connected to the output end of the stop cylinder 302. When the stop cylinder 302 is actuated, it can drive the pressing plate 301 to rise and fall. When the pressing plate 301 is lowered, it presses the cigarette packs on the first conveying channel 100 to limit As the cigarette pack continues to move forward, the pressing plate 301 rises to release the cigarette pack on the first conveying channel 100, so that the cigarette pack can be smoothly moved from the first conveying channel 100 to the second conveying channel 200. More preferably, the output end of the stop cylinder 302 is connected to the pressing plate 301 through a threaded rod 303. The position of the pressing plate 301 can be adjusted by screwing and adjusting, thereby adjusting the pressure of the pressing plate 301 on the cigarette pack, and can be adaptively adjusted according to the size of the conveyed cigarette pack, thereby improving the applicability of the equipment.

[0030] More preferably, the mounting frame includes a crossbeam 304, and a column 305 is provided at each end of the crossbeam 304, so that the mounting frame as a whole forms a door shape and can span across the first conveying channel 100. The stop cylinder 302 is arranged on the crossbeam 304 to facilitate the squeezing and stopping of the cigarette pack. In this embodiment, the crossbeam 304 is arranged horizontally, and a mounting seat 306 is arranged on the crossbeam 304. The mounting seat 306 extends along the horizontal direction on one side of the crossbeam 304. In this embodiment, the first direction and the second direction are perpendicular to each other. The extension direction of the mounting seat 306 corresponds to the downstream direction of the first conveying channel 100, which makes it more convenient to adjust the installation position of the stop cylinder 302 and improve the effect of stopping the cigarette pack. In this embodiment, the column 305 is vertically arranged, the column 305 and the beam 304 are perpendicular to each other, the beam 304 is arranged in a long plate shape as a whole, and the mounting seat 306 is also arranged in a plate shape and extends horizontally on one side of the middle part of the beam 304. The mounting seat 306 and the beam 304 can be integrally formed, so that the processing and forming of the components are convenient.

[0031] Preferably, the rejection component 500 includes a nozzle, which can spray airflow to blow the cigarette packs on the first conveying channel 100 out of the first conveying channel 100. In this embodiment, a blower can also be provided, and the blower is electrically connected to the controller. The nozzle is connected to the blower through an air pipe. The controller can control the airflow blown by the nozzle by controlling the blower, and then control whether to blow the cigarette packs on the first conveying channel 100. When it is necessary to reject the cigarette packs on the first conveying channel 100, the controller starts the blower, so that the nozzle sprays airflow to blow the cigarette packs on the first conveying channel 100 out of the first conveying channel 100.

[0032] In this embodiment, the first monitoring device 41 and / or the second monitoring device 42 are photoelectric detection devices. Preferably, the first monitoring device 41 and the second monitoring device 42 are both photoelectric detection devices. The residence time of the cigarette pack is monitored by the photoelectric detection device. The photoelectric detection signal has high accuracy, which improves the accuracy of the stopping process. The controller is preferably a PLC controller.

[0033] An embodiment is used for explanation. The controller is a PLC controller, and the specific model is Panasonic FP-XHC14T. When the two-in-one trademark paper packaging machine fails, the first monitoring device 41 detects that the residence time of the cigarette pack on the second conveying channel 200 exceeds two seconds. After receiving the signal, the controller starts the stop cylinder 302. The stop cylinder 302 is actuated to cause the pressing plate 301 to descend. The pressing plate 301 presses the cigarette pack at the end of the first conveying channel 100 to limit the cigarette pack from continuing to be conveyed to the second conveying channel 200. At the same time, the cigarette pack on the first conveying channel 100 gradually stops. When the second monitoring device 42 detects that the stop time of the cigarette pack on the second conveying channel 200 exceeds three seconds, the controller starts the blower and sprays air through the nozzle to blow the cigarette pack that continues to be conveyed upstream out of the first conveying channel 100, and the blown cigarette packs are centrally processed, which can avoid the shutdown of the entire equipment and the accumulation, extrusion and deformation of the cigarette packs, which is beneficial to maintaining and improving the overall production progress of the equipment.
