Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of cigarette packaging, and particularly relates to a cigarette packet separating device for a cigarette packet conveying channel. Background Art
[0002] Imaging detection is widely used in cigarette packaging machines. Its function is to conduct a final quality inspection on the cigarette packets that have been packaged by the main machine of the cigarette packaging machine to prevent cigarette packets with quality problems from entering the auxiliary machine of the cigarette packaging machine. The detection principle of imaging detection is to use three high-speed cameras to take pictures of the top surface, front side, rear side, left side and right side of the independent cigarette packets standing horizontally on the belt of the cigarette packet conveying channel, and then compare the feature points in the photos with the reserved points for detection to obtain comparison values. If the comparison value does not exceed the preset value, it means that no abnormality is found in the box of cigarette packets, and then it is released and passed. If the comparison value exceeds the preset value, it is determined that the box of cigarette packets is a defective product, and it needs to be removed by positive pressure blowing.
[0003] Due to the requirement of the detection principle of imaging detection, the cigarette packets passing the detection must be independent cigarette packets to ensure that all five detection surfaces of the cigarette packets are completely photographed and compared. When the cigarette packets on the belt of the cigarette packet conveying channel are tightly attached and continuously conveyed, the imaging detection will not be able to photograph all the detection surfaces of the detected cigarette packet due to the occlusion of the adjacent cigarette packet to the detected cigarette packet, thus causing the failure of the imaging detection, enabling cigarette packets with quality defects to pass through and enter the next process and flow into the market, or misjudging qualified cigarette packets as defective and being wrongly removed, resulting in a large amount of product consumption.
[0004] Patent CN220411964U discloses a conveying track cigarette packet separating device, which realizes cigarette packet separation by installing a paddle with a spring on the cigarette packet conveying channel and relying on the pressure of the paddle. Although this patent can separate most continuous cigarette packets, the separation effect on completely tightly attached continuous cigarette packets is not ideal. Because when the tightly attached cigarette packet hits the decelerating cigarette packet in front, the impact force received by the decelerating cigarette packet will increase, so that two consecutive decelerating cigarette packets will simultaneously break away from the paddle, and thus the cigarette packets entering the imaging detection are still continuous cigarette packets.
[0005] Patent CN217754244U discloses a cigarette packet separating device based on a small packet vision detection system, which realizes cigarette packet separation through a rotating pushing frame after the cigarette packets are turned. This patent requires changing the equipment structure and the cigarette packet conveying direction. It not only has a cumbersome structure and a high expected failure rate, but also affects the cigarette packet process requirements. It is only applicable to specific products and has low applicability. Summary of the Utility Model

[0018] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0019] The cigarette packet separating device for the cigarette packet conveying channel in the present utility model includes a front clamping and conveying assembly at the front side of the cigarette packet conveying channel and a rear clamping and conveying assembly at the rear side of the cigarette packet conveying channel; the front clamping and conveying assembly includes a front upper clamping conveyor belt and a front lower clamping conveyor belt which are symmetrically arranged up and down and rotate synchronously in the same direction; the rear clamping and conveying assembly is symmetrically arranged front and rear with the front clamping and conveying assembly, and includes a rear upper clamping conveyor belt and a rear lower clamping conveyor belt; the front upper clamping conveyor belt and the rear upper clamping conveyor belt rotate synchronously in opposite directions. In this way, by the cooperation of the front upper clamping conveyor belt and the rear upper clamping conveyor belt, pressure can be applied to the upper part of the cigarette packet and the upper part of the cigarette packet can be clamped, and by the cooperation of the front lower clamping conveyor belt and the rear lower clamping conveyor belt, pressure can be applied to the lower part of the cigarette packet and the lower part of the cigarette packet can be clamped. Since the running speed of the front upper clamping conveyor belt is less than the running speed of the belt of the cigarette packet conveying channel, the conveying speed of the cigarette packet can be reduced. After the cigarette packet leaves the cigarette packet separating device, it moves quickly under the drive of the belt of the cigarette packet conveying channel at the bottom of the cigarette packet, while the next cigarette packet is still moving at a low speed under the action of the cigarette packet separating device, so that two adjacent and closely attached cigarette packets are separated. Therefore, the cigarette packet separating device can effectively separate the cigarette packets that are closely and continuously conveyed on the belt of the cigarette packet conveying channel; and for soft box cigarette packets, since there are sealing labels, and the front upper clamping conveyor belt and the rear upper clamping conveyor belt cooperate to clamp the upper part of the cigarette packet, and the front lower clamping conveyor belt and the rear lower clamping conveyor belt cooperate to clamp the lower part of the cigarette packet, when the front upper clamping conveyor belt, the rear upper clamping conveyor belt, the front lower clamping conveyor belt, and the rear lower clamping conveyor belt clamp the soft box cigarette packet, they can avoid the sealing label position in the middle of the soft box cigarette packet and will not damage the sealing label of the soft box cigarette packet; in addition, since the running speed of the front upper clamping conveyor belt is greater than the cigarette output speed of the main machine of the cigarette packaging machine, the normal operation of the main machine of the cigarette packaging machine can be ensured.
[0020] In the present utility model, the front clamping and conveying assembly further includes a front conveyor belt guide plate vertically arranged in the left-right direction, and a front tensioning wheel located on the front side of the front conveyor belt guide plate. Both the front conveyor belt guide plate and the front tensioning wheel are positioned between the front driving shaft and the front driven shaft.

The rear clamping and conveying assembly further includes a rear conveyor belt guide plate and a rear tensioning wheel. In this way, through the setting of the front conveyor belt guide plate, it can play a role in guiding the front upper clamping conveyor belt and the front lower clamping conveyor belt. Since the rear clamping and conveying assembly and the front clamping and conveying assembly are symmetrically arranged front and rear, through the setting of the rear conveyor belt guide plate, it can play a role in guiding the rear upper clamping conveyor belt and the rear lower clamping conveyor belt. This can ensure that the cigarette packs entering the cigarette pack separating device are always subjected to the extrusion forces of the front upper clamping conveyor belt and the rear upper clamping conveyor belt, and are always subjected to the extrusion forces of the front lower clamping conveyor belt and the rear lower clamping conveyor belt.
[0021] In the present utility model, the cigarette pack separating device further includes a driving assembly. The driving assembly includes a motor and a speed reducer. The output shaft of the speed reducer is fixedly connected to one end of a driving gear shaft horizontally arranged in the front-back direction. A front cylindrical helical bevel gear is sleeved and fixed on the front part of the driving gear shaft, and a rear cylindrical helical bevel gear is sleeved and fixed on the rear part of the driving gear shaft.

The front driving shaft and the front driven shaft are connected through a front guide plate. The front driven shaft is adjusted in the front-back position along with the front driving shaft to realize the adjustment of the front-back horizontal distance between the front driven shaft and the rear driven shaft. After the front-back position adjustment of the front driving shaft and the front driven shaft is in place, the front guide plate is detachably connected to the front frame on the front side of the cigarette pack conveying channel. In this way, according to the thickness of the cigarette pack, by adjusting the front-back position of the front moving transmission gear relative to the front cylindrical helical bevel gear, the front-back horizontal distance between the front driving shaft and the rear driving shaft is adjusted, and further the front-back horizontal distance between the front upper driving pulley and the rear upper driving pulley and the front-back horizontal distance between the front lower driving pulley and the rear lower driving pulley are adjusted. And the front driving shaft and the front driven shaft are connected through the front guide plate, so that the front driven shaft can be adjusted in the front-back position along with the front driving shaft to realize the adjustment of the front-back horizontal distance between the front driven shaft and the rear driven shaft, and further realize the adjustment of the front-back horizontal distance between the front upper driven pulley and the rear upper driven pulley and the front-back horizontal distance between the front lower driven pulley and the rear lower driven pulley.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0029] As Figure 1 and Figure 2As shown in the figure, a cigarette pack separation device for a cigarette pack conveying channel. The cigarette packs 1 on the belt 30 of the cigarette pack conveying channel are closely attached and horizontally conveyed from left to right. The cigarette pack separation device includes a front clamping and conveying assembly located on the front side of the cigarette pack conveying channel and a rear clamping and conveying assembly located on the rear side of the cigarette pack conveying channel. The front clamping and conveying assembly includes a front upper clamping conveyor belt 2 and a front lower clamping conveyor belt 3 that are symmetrically arranged up and down and rotate synchronously in the same direction. The rear clamping and conveying assembly is symmetrically arranged with the front clamping and conveying assembly front and back, and includes a rear upper clamping conveyor belt 4 and a rear lower clamping conveyor belt 5. The front upper clamping conveyor belt 2 and the rear upper clamping conveyor belt 4 rotate synchronously in opposite directions, and the running speed of the front upper clamping conveyor belt 2 is less than the running speed of the belt of the cigarette pack conveying channel and greater than the cigarette outlet speed of the main machine of the cigarette pack 1 packing machine. The front upper clamping conveyor belt 2 and the rear upper clamping conveyor belt 4 cooperate to clamp the upper part of the cigarette pack 1, and the front lower clamping conveyor belt 3 and the rear lower clamping conveyor belt 5 cooperate to clamp the lower part of the cigarette pack 1, so as to reduce the conveying speed of the cigarette pack 1 and separate adjacent and closely attached cigarette packs 1.
[0030] In this way, the front upper clamping conveyor belt 2 and the rear upper clamping conveyor belt 4 cooperate to apply pressure to the upper part of the cigarette pack 1 and clamp the upper part of the cigarette pack 1. The front lower clamping conveyor belt 3 and the rear lower clamping conveyor belt 5 cooperate to apply pressure to the lower part of the cigarette pack 1 and clamp the lower part of the cigarette pack 1. Since the running speed of the front upper clamping conveyor belt 2 is less than the running speed of the belt of the cigarette pack conveying channel, the conveying speed of the cigarette pack 1 can be reduced. After the cigarette pack 1 leaves the cigarette pack separation device, it moves quickly under the drive of the belt 30 of the cigarette pack conveying channel at the bottom of the cigarette pack 1, while the next cigarette pack 1 still moves slowly under the action of the cigarette pack separation device, so as to separate two adjacent and closely attached cigarette packs 1. Therefore, the use of this cigarette pack separation device can effectively separate the cigarette packs 1 that are closely and continuously conveyed on the belt 30 of the cigarette pack conveying channel. Moreover, for soft-pack cigarette packs 1, because they have sealing labels, the front upper clamping conveyor belt 2 and the rear upper clamping conveyor belt 4 cooperate to clamp the upper part of the cigarette pack 1, and the front lower clamping conveyor belt 3 and the rear lower clamping conveyor belt 5 cooperate to clamp the lower part of the cigarette pack 1. In this way, the front upper clamping conveyor belt 2, the rear upper clamping conveyor belt 4, the front lower clamping conveyor belt 3 and the rear lower clamping conveyor belt 5 can avoid the sealing label position in the middle of the soft-pack cigarette pack 1 when clamping the soft-pack cigarette pack 1, and will not damage the sealing label of the soft-pack cigarette pack 1. In addition, since the running speed of the front upper clamping conveyor belt 2 is greater than the cigarette outlet speed of the main machine of the cigarette pack 1 packing machine, the normal operation of the main machine of the cigarette pack 1 packing machine can be ensured.
[0031] Among them, the front clamping and conveying assembly further includes a vertical front driving shaft 6 and a front driven shaft 7. A front upper driving pulley 8 is sleeved and fixed on the upper part of the front driving shaft 6, and a front lower driving pulley 9 is sleeved and fixed on the lower part of the front driving shaft 6. A front upper driven pulley 10 is sleeved and fixed on the upper part of the front driven shaft 7, and a front lower driven pulley 11 is sleeved and fixed on the lower part of the front driven shaft 7.

The rear clamping and conveying assembly further includes a rear driving shaft 12, a rear driven shaft, a rear upper driving pulley 13, a rear lower driving pulley 14, a rear upper driven pulley 15, and a rear lower driven pulley 16. The front-to-rear horizontal distance between the front upper driving pulley 8 and the rear upper driving pulley 13 is equal to the front-to-rear horizontal distance between the front upper driven pulley 10 and the rear upper driven pulley 15.
[0032] Among them, the front clamping and conveying assembly further includes a front conveyor belt guide plate 17 arranged vertically in the left-right direction, and a front tensioning pulley 18 located on the front side of the front conveyor belt guide plate 17. Both the front conveyor belt guide plate 17 and the front tensioning pulley 18 are located between the front driving shaft 6 and the front driven shaft 7. The upper part of the rear side of the front conveyor belt guide plate 17 is provided with an upper through slot that penetrates horizontally from left to right, and the lower part is provided with a lower through slot that penetrates horizontally from left to right. The front upper clamping conveyor belt 2 passes through the upper through slot and is tensioned on the upper part of the front tensioning pulley 18, and the outer side of the front upper clamping conveyor belt 2 protrudes outside the upper through slot. The front lower clamping conveyor belt 3 passes through the lower through slot and is tensioned on the lower part of the front tensioning pulley 18, and the outer side of the front lower clamping conveyor belt 3 protrudes outside the lower through slot. The rear clamping and conveying assembly further includes a rear conveyor belt guide plate 19 and a rear tensioning pulley 20. In this way, through the setting of the front conveyor belt guide plate 17, it can play a role in guiding the front upper clamping conveyor belt 2 and the front lower clamping conveyor belt 3. Since the rear clamping and conveying assembly and the front clamping and conveying assembly are arranged symmetrically front and rear, through the setting of the rear conveyor belt guide plate 19, it can play a role in guiding the rear upper clamping conveyor belt 4 and the rear lower clamping conveyor belt 5. In this way, it can ensure that the cigarette packet 1 entering the cigarette packet separating device is always subjected to the squeezing force of the front upper clamping conveyor belt 2 and the rear upper clamping conveyor belt 4, and is always subjected to the squeezing force of the front lower clamping conveyor belt 3 and the rear lower clamping conveyor belt 5.
