Description

Cigarette packet combined detection device

Technical Field

The invention relates to the technical field of tobacco electric automatic detection, in particular to a tobacco packet combined detection device.

Background

In the prior art, a cigarette packet visual appearance detection device is usually adopted to detect the quality of cigarette packets, as shown in fig. 1, the cigarette packet quality detection device in the prior art comprises the cigarette packet visual appearance detection device, the cigarette packet visual appearance detection device is arranged at the downstream of a cigarette packaging machine, and a conveying channel is arranged between the cigarette packet visual appearance detection device and the cigarette packaging machine. The cigarette packet output by the cigarette packaging machine is directly input to the cigarette packet visual appearance detection device through the conveying channel. In addition, if the cigarette packet connection appears in front of the inlet of the cigarette packet visual appearance detection device, a cigarette packet separation device is generally added.

However, the existing cigarette packet quality detection device has obvious defects, and the defects are as follows: the quality detection requirements of the existing cigarette packets cannot be met. The existing cigarette packet quality detection device cannot effectively detect and reject ultra-wide cigarette packets. In the detection process, part of ultra-wide cigarette packets often block in the cigarette packet appearance visual detection unit, so that abnormal cigarette packets cannot be detected and removed continuously. And part of ultra-wide cigarette packets can smoothly enter downstream equipment through appearance detection, so that blockage and stop can easily occur, and the equipment mechanism is displaced, deformed and even broken and damaged. And a part of ultra-wide cigarette packets flow into a finished product warehouse, so that the product quality is seriously influenced.

The ultra-wide cigarette packet is defined as follows: in the production process of the cigarette packaging machine, if the conditions of cigarette wrinkle resistance, wrinkle resistance of inner and outer packing paper, scattering of outer packing paper, breakage of packing paper and the like occur, the cigarette packet can become wide. If the cigarette packet is beyond the range of the process standard requirement, the cigarette packet is called as an ultra-wide cigarette packet or an ultra-wide cigarette packet.

The reason that the existing cigarette packet quality detection device cannot effectively detect and reject ultra-wide cigarette packets is that a contradiction point exists between two design requirements of a cigarette packet conveying channel, and the existing cigarette packet quality detection device is mainly embodied as follows:

the first design requirement is that the conveying channel can restrain the cigarette packet at an operation point, namely, the swing of the cigarette packet in a non-conveying direction is reduced as much as possible. The method has two points of significance for direction constraint of the non-transport direction of the cigarette packet: 1. the fluctuation of the relative position of the light source in the cigarette packet and cigarette packet visual appearance detection device is reduced, and the stability of illumination conditions is improved; 2. the fluctuation of the relative position of the camera in the cigarette packet and the visual appearance detection device of the cigarette packet is reduced, and the stability of the projection position of various detection objects on the cigarette packet on a photosensitive element of the camera is improved.

The second design requirement is: the conveying channel also needs to have the function of ensuring the smooth passing of the cigarette packets, so that the cigarette packets are not decelerated, stopped, blocked or connected in the conveying process. The speed change of the cigarette packet transportation direction is also reduced as much as possible. The cigarette packet is disconnected and the deceleration is small, which is beneficial to the following two points: 1. the cigarette packet identification device is beneficial to identifying each independent cigarette packet and avoiding the mutual shielding of the cigarette packets. The cigarette packet is not continuously wrapped, so that each independent cigarette packet can be identified by the shooting sensor group, and each independent cigarette packet can also be well identified by the removing sensor. 2. The cigarette packet shooting and removing positioning are facilitated. After the sensor detects the tobacco bale of high-speed transportation, the response time and procedure of electric system all have may be provided with the time delay, and the tobacco bale disconnected then can promote detecting system's fault-tolerant rate for the system can in time revise, reduces tobacco bale positioning error.

In order to meet the first design requirement, one of the important measures requiring a small swing during the passage of the cigarette packets is to reduce the width of the conveying channel at the operating point, and once the width of the conveying channel at the operating point is reduced, although the first design requirement is met, the second important design requirement cannot be met.

On the contrary, if the width of the conveying channel at the operation point is increased to meet the second design requirement, when the ultra-wide cigarette packet occurs, the conditions of blocking, speed reduction, cigarette packet connection and the like are less generated in the process of passing the cigarette packet, but the important first design requirement can not be met.

The width of the conveying channel is large or small, and the effects of the large or small conveying channel are mutually contradictory. Although the sub-packaging device can be arranged immediately upstream of the cigarette packet visual appearance detection device, if an ultra-wide cigarette packet exists after sub-packaging, the cigarette packet visual appearance detection device can block the continuous package again.

Therefore, the ultra-wide cigarette packet can cause downstream equipment of the cigarette packaging machine to not work normally, but the cigarette packaging machine does not have the ultra-wide cigarette packet detection function, and the currently and generally used cigarette packet visual appearance detection system can block the cigarette packet due to the ultra-wide cigarette packet and cannot reliably detect and reject the ultra-wide cigarette packet. The other part of the ultra-wide cigarette packet with the relatively small width can enter downstream equipment through a cigarette packet visual appearance detection device, and if the ultra-wide cigarette packet enters the downstream equipment, the downstream equipment is blocked and stopped, and an equipment mechanism is displaced, deformed or even broken and damaged; and part of the waste water flows into a finished product warehouse, so that the product quality is seriously influenced.

Therefore, there is an urgent need to design a cigarette packet combined detection device capable of detecting and eliminating ultra-wide cigarette packets and executing cigarette packet appearance detection.

In view of the above-mentioned drawbacks, the present inventors have finally obtained the present invention through long-term research and practice.

Example one

The embodiment of the invention provides a tobacco bale combined detection device, which comprises a tobacco bale ultra-wide detection and removal device 50, a tobacco bale visual appearance detection device 60 and a controller 40.

The cigarette packet ultra-wide detection and removal device 50 is arranged at the downstream of the cigarette packaging machine 70, and the cigarette packet ultra-wide detection and removal device 50 is arranged at the upstream of the cigarette packet visual appearance detection device 60.

The tobacco bale ultra-wide detection and removal device 50 and the tobacco bale visual appearance detection device 60 are respectively electrically connected with the controller 40.

Conveying channels are arranged between the cigarette packaging machine 70 and the cigarette packet ultra-wide detection and removal device 50, and between the cigarette packet ultra-wide detection and removal device 50 and the cigarette packet visual appearance detection device 60.

The tobacco bale is super wide to detect and reject the device 50, is used for detecting and rejecting super wide tobacco bale. The beneficial effects are that: the ultra-wide cigarette packet can be prevented from entering the cigarette packet visual appearance detection device 60 and other downstream equipment, so that the blockage is avoided.

The cigarette packet visual appearance detection device 60 is used for detecting the appearance quality of cigarette packets and rejecting unqualified cigarette packets which do not meet the appearance process quality standard.

The cigarette packet detection process comprises the following steps: firstly, a tobacco bale ultra-wide detection and removal device 50 is used for detecting whether the tobacco bale is ultra-wide or not, and then a tobacco bale visual appearance detection device 60 is used for detecting the appearance quality of the tobacco bale.

The cigarette packet combined detection device provided by the invention has the beneficial effects that:

1. the relative stability of the cigarette packet position and the camera position in the cigarette packet visual appearance detection device 60 can be improved.

Because the ultra-wide cigarette packet is detected and rejected by the cigarette packet ultra-wide detection and rejection device 50, the width of an appearance detection channel in the cigarette packet visual appearance detection device 60 is allowed to be reduced to the upper limit of the width of the qualified cigarette packet, so that the swing of the cigarette packet can be reduced. The relative stability of tobacco bale position and camera position has been guaranteed like this to improve tobacco bale visual appearance detection device 60's detection precision and detection reliable and stable. The distance and the angle between the cigarette packet and the photosensitive element of the camera affect the size of the imaging size of the cigarette packet on the photosensitive element.

2. The relative stability of the cigarette packet position and the light source position in the cigarette packet visual appearance detection device 60 can be improved.

Because the ultra-wide cigarette packet is detected and rejected by the ultra-wide cigarette packet detecting and rejecting device 50, the width of an appearance detecting channel in the cigarette packet visual appearance detecting device 60 is allowed to be reduced to the upper limit of the width of the qualified cigarette packet, so that the swing of the cigarette packet can be reduced. Thus, the relative stability of the cigarette packet position and the light source position is ensured, the illumination stability is improved, the stability of brightness or color in the image is effectively reduced, and the detection precision and the detection stability and reliability of the cigarette packet visual appearance detection device 60 are improved.

3. The ultra-wide scattered broken cigarette packets are prevented from entering the cigarette packet visual appearance detection device 60, and the interference of cigarettes, paper scraps and the like on the cigarette packet visual appearance detection device 60 is reduced.

4. The defect that the detection and elimination of the ultra-wide cigarette packet are unreliable due to blockage generated by the conventional appearance detection device is overcome.

5. The ultra-wide cigarette packet can be prevented from entering downstream equipment, so that the downstream equipment mechanism is prevented from being displaced, deformed and even broken and damaged;

6. can avoid super wide and unqualified tobacco bale to flow into market.

7. The tobacco bale ultra-wide detection and removal device 50 and the tobacco bale visual appearance detection device 60 are combined to have obvious effect and complement advantages and disadvantages.

Example two

The difference between this embodiment and the first embodiment is:

the tobacco bale ultra-wide detection and rejection device 50 provided by the embodiment of the invention comprises a conveying belt 1, a first blocking plate 20, a movable blocking plate component, a blocking sensor 15 and a rejection mechanism.

The conveyer belt 1, the first blocking plate 20 and the movable blocking plate assembly are surrounded together to form an ultra-wide blocking passage. And a rejection mechanism is arranged at the downstream of the ultra-wide blocking channel. The probe of the occlusion sensor 15 points to an ultra-wide occlusion channel.

The controller 40 is electrically connected to the blockage sensor 15 for determining whether the ultra-wide blocked channel is blocked. The controller 40 is also connected to and controls the movable barrier plate assembly, the conveyor belt 1 and the rejection mechanism, respectively.

The first blocking plate 20 is matched with the movable blocking plate component for use, and can be used for blocking the ultra-wide cigarette packet.

Under normal conditions, qualified tobacco bales can smoothly pass through the ultra-wide blocking channel, so that the tobacco bales enter downstream. However, when an ultra-wide cigarette pack is present, the ultra-wide cigarette pack may be blocked by the first barrier plate 20 and the movable barrier plate assembly. The controller can judge whether an ultra-wide cigarette packet is blocked in the ultra-wide blocking channel or not through a signal of the blocking sensor 15, and judge the blocking type, wherein the blocking type comprises cigarette packet blocking deceleration and cigarette packet blocking stop.

When the cigarette packet is blocked and decelerated, the controller 40 starts the rejecting mechanism in a delayed manner, and when the cigarette packet is blocked and stopped, the controller 40 controls the movable blocking plate component to act, so that the ultra-wide blocking channel is widened, and the ultra-wide cigarette packet can enter a working area of the rejecting mechanism at the downstream of the ultra-wide blocking channel. The controller 40 further controls the rejecting device to be started in a delayed mode so as to reject the ultra-wide cigarette packets.

The tobacco bale ultra-wide detection and removal device 50 provided by the invention has the beneficial effects that: the device can detect the ultra-wide cigarette packet and then reject the ultra-wide cigarette packet, so that the deflection, deformation and even fracture damage of a downstream packaging machine mechanism can be avoided, and meanwhile, the ultra-wide cigarette packet can be prevented from entering a conveying channel and downstream equipment. The width of the downstream equipment operation point can be reduced, and the constraint effect on the cigarette packet is improved, so that the operation precision and the operation success rate are improved. The detection and elimination process is fully automatic, and manual participation is not needed.

EXAMPLE III

The present embodiment is different from the second embodiment in that:

the upper reaches of the super-wide blocking channel are provided with a first guide rod 2 and a second guide rod 3, and the first guide rod 2 and the second guide rod 3 are respectively arranged on two sides of the conveying belt 1 at the upper reaches of the super-wide blocking channel. The conveying belt 1, the first guide rod 2 and the second guide rod 3 jointly surround to form a conveying channel, the conveying channel is communicated with the ultra-wide blocking channel, and the conveying channel is used for conveying cigarette packets.

The movable stop plate assembly comprises a stop sheet 19, a movable second stop plate and a driving device, the movable second stop plate is connected with the stop sheet 19, and the stop sheet 19 is arranged on the inner side of the movable second stop plate. The controller 40 controls the position of the movable second blocking plate by the driving means. The movable barrier plate assembly constitutes the blockage relieving unit.

In this embodiment, the second movable blocking plate is preferably a rotation blocking plate 16, and the rotation blocking plate 16 is connected to the first guide rod 2 through a hinge 11. The driving means is an electromagnet 12. The blocking piece 19 is disposed inside the rotation blocking plate 16. The rotating blocking plate 16 can rotate around a shaft, and the rotating blocking plate 16 and the blocking piece 19 move together in a direction away from the ultra-wide blocking channel by rotating, so that the ultra-wide blocking channel is widened. The widened ultra-wide blocking passage allows ultra-wide cigarette packets to pass through. The electromagnet 12 is connected with an electromagnet support 13, and the electromagnet 12 is arranged outside the rotation blocking plate 16 through the electromagnet support 13. The electromagnet 12 is also connected to a controller 40. The controller 40 is capable of controlling the operating state of the electromagnet 12. The rotation blocking plate 16 is made of magnetizable material. When the current of the electromagnet 12 is conducted, magnetic force is generated between the electromagnet 12 and the rotary blocking plate 16, and the electromagnet 12 is fixed on the electromagnet support 13, so that under the action of the magnetic force, relative motion can occur between the electromagnet 12 and the rotary blocking plate 16, the rotary blocking plate 16 can rotate outwards around the axis of the hinge 11, that is, the blocking sheet 19 can move towards the direction far away from the first blocking plate 20, and the purpose of widening an ultra-wide blocking passage is achieved.

The working process of the blockage relieving unit is as follows: during cigarette packet detection, the blocking sheet 19 and the first blocking plate 20 form a wedge-shaped channel. When the ultra-wide cigarette packet 5 enters the wedge-shaped ultra-wide blocking channel, the ultra-wide cigarette packet 5 is blocked in the ultra-wide blocking channel, when the blocking time exceeds a blocking stop time threshold value, the blocking removing unit is started immediately, the electromagnet 12 opens the rotary blocking plate 16, and the ultra-wide cigarette packet 5 which causes the ultra-wide blocking stop is unblocked and passes through the blocking channel. When no smoke pack is in front of the blockage sensor 15, the rotary blocking plate 16 is closed in a delayed mode, namely the blocking piece 19 is reset.

In addition, a limiting device is further disposed outside the rotation blocking plate 16 for limiting the rotation angle of the rotation blocking plate 16. Preferably, the limiting device in this embodiment comprises a limiting adjusting bolt 17 and a limiting bracket 18. The limit bracket 18 is arranged at the outer side of the rotary blocking plate 16, and the limit adjusting bolt 17 is arranged on the limit bracket 18. The length of the limit adjusting bolt 17 is adjustable, and the limit value of the rotation angle of the rotary blocking plate 16 changes along with the length change of the limit adjusting bolt 17. The limiting bracket 18 and the limiting adjusting bolt 17 are used for limiting and adjusting the radian of the rotating opening of the blocking sheet 19 and the rotating blocking plate 16, so that the cigarette packet can smoothly pass through the widened blocking detection channel.

The rotary blocking plate 16 is connected with one end of the blocking piece 19, and a wedge-shaped structure is formed between the rotary blocking plate 16 and the blocking piece 19. The rotation blocking plate 16 is further provided with a width adjustment means, preferably a width adjustment bolt 14. The length of the width adjusting bolt 14 is adjustable, one end of the width adjusting bolt 14 abuts against the blocking sheet 19, the blocking sheet 19 can be close to or far away from the first blocking plate 20 by adjusting the length of the width adjusting bolt 14, namely, the effective width of the ultra-wide blocking channel can be adjusted by adjusting the length of the width adjusting bolt 14, so that detection on cigarette cases with different sizes is adapted, and the compatibility of the ultra-wide cigarette case detecting and removing device 50 on cigarette cases with various sizes is improved. The minimum width of the ultra-wide blocking channel is the width at the minimum distance between the blocking plate 19 and the first blocking plate 20, which is also referred to as the blocking point or the blocking surface. When the ultra-wide blocking channel is in the minimum width, a certain residual amount is left after the width of the cigarette packet 4 is subtracted from the distance formed by the first blocking plate 20 and the blocking sheet 19 on the inner side of the rotating blocking plate 16, so that the ultra-wide cigarette packet can not pass through smoothly, and the blockage deceleration or the blockage stop can be generated only when the ultra-wide cigarette packet is close to or exceeds the maximum width allowed by the process standard. The cigarette packet which is detected by the cigarette packet ultra-wide detection and removal device is not guaranteed to be a qualified cigarette packet, and further detection such as weight detection and the like needs to be carried out by other subsequent cigarette packet quality detection devices.

The blocking sheet 19 is made of elastic materials, and the width adjusting bolt 14 is used for adjusting the shape of the blocking sheet 19 so as to realize the function of adjusting the width of the ultra-wide blocking channel, so that the tobacco bales which are not ultra-wide can smoothly pass through, and the bad tobacco bales with ultra-wide can generate blocking stop or speed reduction in the channel. In addition, since the blocking sheet 19 does not need to be elastically deformed to remove the blockage of the ultra-wide cigarette packet, the blocking sheet 19 should be selected to have sufficient rigidity, but the blocking sheet 19 still needs to have appropriate elasticity to ensure that the elastic width adjustment can be performed. The width adjustment bolt 14 is provided with a lock nut. Of course, the width adjusting bolt can be omitted, and the width adjusting bolt is directly set to be a fixed width during installation.

The blocking sensor 15 is used for detecting whether a cigarette packet exists in the ultra-wide blocking passage, namely, for detecting the passing state of the cigarette packet or the cigarette packet string. The tobacco bale ultra-wide detection and removal device is arranged close to the packing machine, tobacco bales are evenly and intermittently output by the cigarette packing machine at a certain speed, and the tobacco bales are evenly spaced and have no ultra-wide tobacco bale and are not connected. The cigarette packet combination formed by connecting the front end and the rear end of a certain cigarette packet is called a cigarette packet string and is used as cigarette packet blocking treatment. The blockage sensor 15 is used in combination with a timer in the controller 40 to obtain the time taken by the cigarette packet to pass through the ultra-wide blockage passage. The blockage sensor 15 is connected to a timer in the controller 40, and the timer counts the time from the detection of the front end signal of the cigarette packet by the blockage sensor 15 to the disappearance of the rear end signal of the cigarette packet to obtain the time used by the cigarette packet when passing through the ultra-wide blockage passage, and the timer is also called a blockage timer and can be a software or hardware timer.

The blocking sensor 15 can be a capacitive sensor, a photoelectric sensor, an optical fiber sensor, an inductive sensor, etc., as long as it can detect whether the cigarette packet exists in the ultra-wide blocking channel and has enough response speed.

The controller 40 judges whether the cigarette packet is blocked according to the signal of whether the cigarette packet is present, wherein the blocking type comprises the following steps: cigarette packet blocking deceleration and cigarette packet blocking stop. The controller 40 counts to obtain the cigarette packet passing time, and the controller 40 judges whether the cigarette packet is blocked and decelerated or stopped. When the cigarette packet is blocked and decelerated, the controller 40 controls the blockage removing unit not to be started, the cigarette packets with less ultra-wide quantity can be decelerated and passed, and the controller 40 starts the rejecting mechanism in a delayed mode. When the cigarette packet is blocked and stopped, the controller 40 controls the blockage relieving unit to be started immediately to relieve the blockage, namely the electromagnet 12 opens the rotary blocking plate 16 to enable the ultra-wide cigarette packet which is blocked and stopped to relieve the blockage to pass through the ultra-wide blocking channel. And the controller 40 controls the delayed activation rejection mechanism.

The controller 40 includes a timer and a judgment means. The timer is used for measuring the passing time of the cigarette packet; and the judging device is used for judging whether the blockage occurs or not and judging the type of the blockage, namely judging whether the tobacco bale passing time is more than or equal to the set blockage deceleration time threshold or the blockage stopping time threshold. The cigarette packet smooth passing time threshold is smaller than the blocking deceleration time threshold, and the blocking deceleration time threshold is smaller than the blocking stop time threshold.

The rejecting mechanism is arranged at the downstream of the ultra-wide blocking channel and is adjacent to the ultra-wide blocking channel and used for rejecting ultra-wide cigarette packets. The cigarette packet is rejected by starting the rejecting mechanism in a delayed mode when the cigarette packet is blocked and decelerated or is blocked and stopped. The rejecting mechanism can be a motor type rejecting mechanism, a cylinder type rejecting mechanism or an air jet type rejecting mechanism. In this embodiment, the rejecting mechanism is preferably an air-jet rejecting mechanism, and the air-jet rejecting mechanism includes an air pump, a rejecting solenoid valve 31, and a rejecting air nozzle 32. The rejection solenoid valve 31 is connected with the controller 40, the air pump and the rejection air nozzle 32 respectively. The controller 40 controls the opening and closing of the reject solenoid valve 31. When the eliminating electromagnetic valve 31 is in a conducting state, the air pump is communicated with the eliminating air nozzle 32, and the ultra-wide cigarette packet can be pushed away from the conveying belt 1 through the eliminating opening 34 by high-pressure air. After the controller 40 judges that the tobacco bale is ultra wide, a removing signal is sent to the removing electromagnetic valve 31 to remove the tobacco bale, namely, after the controller 40 judges that the tobacco bale is ultra wide, the removing electromagnetic valve is switched on and the air flow is discharged from the removing air nozzle 32, so that the tobacco bale is removed.

The third blocking plate is also provided with a width adjustment device, preferably a width adjustment bolt 14. The length of the width adjusting bolt 14 is adjustable, one end of the width adjusting bolt 14 abuts against the blocking sheet 19, the blocking sheet 19 can be close to or far away from the first blocking plate 20 by adjusting the length of the width adjusting bolt 14, namely, the effective width of the ultra-wide blocking channel can be adjusted by adjusting the length of the width adjusting bolt 14, so that detection on cigarette cases of different sizes is adapted, and the compatibility of the ultra-wide cigarette case detection and removal device 50 on cigarette cases of various sizes is improved. The minimum width of the ultra-wide blocking channel is the width at the minimum separation of the blocking plate 19 and the first blocking plate 20, which is also referred to as the blocking point or the blocking face. When the ultra-wide blocking channel is in the minimum width, a certain residual amount is left after the width of the cigarette packet 1 is subtracted from the distance formed by the first blocking plate 20 and the blocking sheet 19 on the inner side of the third blocking plate, so that the ultra-wide cigarette packet can not pass through smoothly, and the blockage deceleration or the blockage stop can be generated only when the ultra-wide cigarette packet is close to or exceeds the maximum width allowed by the process standard.
